According to that map, Oklahoma is basically toast. This probably rivals the conditions on Mars.

Parts of northern OK and southern KS received over 2 inches of rain this evening as activity was much more widespread than forecast. Hoping we get some of that to the south over the next few days as the front stalls. Several days of scattered storms would help keep the heat down and put a dent in the drought.

Actually the conditions on Mars are the daytime surface temperature is about 80 F during rare summer days, to -200 F at the poles in winter. The AIR temperature, however, rarely gets much above 32 F.

Colorado Springs and Denver can get temps. in the 90's often in the summer, but the humidity is low and afternoon thunderstorms and clouds that develop over the Front Range move east and cool it off almost every day.

.DISCUSSION...

...EXCESSIVE HEAT WARNING THROUGH SUNDAY...

UNFORTUNATELY... THE UNUSUAL HAS BECOME THE USUAL WITH REGARDS TO
THE INTENSE HEAT THIS SUMMER OVER THE CWA. TEMPERATURES NEAR OR
EXCEEDING RECORD HIGH TEMPERATURES ARE EXPECTED THROUGH THE WEEKEND
INTO EARLY NEXT WEEK. MODELS STILL SHOWING A PATTERN SHIFT BEGINNING
AROUND TUESDAY AND CONTINUING THROUGH THE REST OF THE WEEK.

THE OUTFLOW/FRONTAL BOUNDARY WILL PLAY A PRETTY BIG ROLE IN THE
WEATHER THROUGH THE WEEKEND. THE STALLED BOUNDARY... WITH CLOUD
COVER FROM OVERNIGHT CONVECTION... SLOWED THE WARM UP OVER THE
NORTHERN HALF OF OKLAHOMA. HOWEVER... TEMPERATURES HAD ONCE AGAIN
EXCEEDED 100 DEGREES OVER ALL BUT OUR NORTHERN BORDER COUNTIES.
EXPECT ISOLATED THUNDERSTORMS TO DEVELOP NEAR THIS BOUNDARY LATE
THIS AFTERNOON INTO THIS EVENING. ADDITIONAL THUNDERSTORMS ARE
POSSIBLE OVER THE HIGHER TERRAIN... WHICH MAY THEN IN TURN MOVE INTO
NORTHERN OKLAHOMA OVERNIGHT.

THE BOUNDARY DOES LIFT NORTH TOMORROW INTO SATURDAY... BUT WILL
PROBABLY WAFFLE BACK AND FORTH INTO OKLAHOMA FRIDAY NIGHT AND
SATURDAY. THE PLACEMENT OF THE BOUNDARY AND ASSOCIATED CLOUD COVER
TO THE NORTH WILL DETERMINE THOSE THAT GET HOT... AND THOSE THAT GET
REALLY HOT. THE FORECAST TEMPERATURES FOR OKLAHOMA CITY COULD END
UP BEING A FEW DEGREES TOO WARM TOMORROW AND SATURDAY IF THE
BOUNDARY PUSHES FURTHER SOUTH THAN FORECAST.

THE MODELS CONTINUE TO INDICATE A PATTERN SHIFT EARLY NEXT WEEK...
WITH THE RIDGE BUILDING OVER THE WEST... AND NORTHWEST FLOW
DEVELOPING OVER THE SOUTHERN PLAINS. IF THAT DOES INDEED OCCUR...
TEMPERATURES MAY ACTUALLY APPROACH NORMAL FOR THIS TIME OF YEAR.
SOME GUIDANCE NUMBERS EVEN HAVE PARTS OF CENTRAL AND NORTHERN
OKLAHOMA A FEW DEGREES BELOW NORMAL. WE WILL NOT GET TOO CARRIED
AWAY AT THIS POINT... BUT WILL WATCH CLOSELY.

Brady Block Fest cancelled in Tulsa after storms knocked down the stage rigging and blew over tents. This was before Primus and Flaming Lips were able to play.

On the plus side there is a lot of welcome rain coming down over the central and northern half of the state. This rain alone, and any more that we get, should help keep temps. down several degrees over the next few days. Humidity will increase however..

NWS STORM PREDICTION CENTER NORMAN OK
1256 AM CDT SUN AUG 07 2011

VALID 081200Z - 091200Z

...THERE IS A SLGT RISK OF SVR TSTMS FROM A PORTION OF THE CNTRL AND
SRN PLAINS...MID-UPPER MS VALLEY AND A PORTION OF THE TN AND OH
VALLEYS...

...SYNOPSIS...

GRADUAL AMPLIFICATION OF LARGE SCALE TROUGH WILL OCCUR OVER THE ERN
HALF OF THE U.S. THROUGH MONDAY. UPPER TROUGH NOW OVER THE UPPER MS
VALLEY WILL MOVE THROUGH THE NERN STATES EARLY IN THE PERIOD
FOLLOWED BY A STRONGER SHORTWAVE TROUGH THAT WILL MOVE INTO THE
UPPER MS VALLEY MONDAY AFTERNOON. COLD FRONT WILL ADVANCE THROUGH
THE NERN STATES EARLY MONDAY IN ASSOCIATION WITH LEAD IMPULSE.
TRAILING PORTION OF THIS BOUNDARY WILL EXTEND WWD THROUGH MO AND
KS/NRN OK DURING THE LATE AFTERNOON. ANOTHER FRONT WILL MOVE INTO
THE NRN PLAINS AND UPPER MS VALLEY IN ASSOCIATION WITH UPPER MS
VALLEY IMPULSE.

...CNTRL PLAINS THROUGH MID MS VALLEY REGION...

STORMS SHOULD BE ONGOING PRIMARILY WITHIN ZONE OF WARM ADVECTION AND
ISENTROPIC ASCENT NORTH OF THE FRONT FROM PORTION OF NEB...KS INTO
MO. STORMS WILL SHIFT EWD AND MAY DECREASE DURING THE DAY AS THE LLJ
WEAKENS. THE STORMS WILL SERVE TO REINFORCE PRE-EXISTING BAROCLINIC
ZONE AS THE WARM SECTOR TO THE SOUTH DESTABILIZES WITH THE ONSET OF
DIABATIC WARMING. POTENTIAL WILL EXIST FOR STORMS TO REDEVELOP ALONG
AND NORTH OF THIS BOUNDARY FROM CNTRL/NRN OK AND KS INTO MO AS
SURFACE LAYER WARMS AND CAP WEAKENS. OTHER STORMS MAY DEVELOP OVER
WRN NEB IN THE MORE DEEPLY MIXED BOUNDARY LAYER AND ALONG TRAILING
END OF SEWD MOVING COLD FRONT. VORT MAX NOW OVER NRN CA IS FORECAST
TO ACCELERATE INTO THE CNTRL PLAINS MONDAY AFTERNOON. STRENGTHENING
HEIGHT GRADIENT WITH THIS IMPULSE AND SHORTWAVE TROUGH DROPPING INTO
THE UPPER MS VALLEY WILL CONTRIBUTE TO 40-45 KT EFFECTIVE SHEAR
SUPPORTIVE OF SUPERCELLS AND BOWING SEGMENTS OVER MUCH OF THIS
REGIONS. ACTIVITY MAY EVENTUALLY EVOLVE INTO AN MCS AS LLJ
STRENGTHENS OVERNIGHT AND CONTINUE EWD THROUGH THE TN VALLEY AND SRN
PORTIONS OF THE OH VALLEY.

A few of those lines every day for a week would probably get things closer to normal. Northern and western parts of the OKC metro up toward Stillwater and up to Tulsa received over an inch of rain yesterday. The severe weather in Tulsa that caused the music festival to be cancelled also knocked out power and tore down tree limbs in midtown.

We will just need to see much more rain out of them. Here are the current Drought Termination figures if we wanted to get out of it with in a month.

Unfortunately, we would need 18 to 24 inches of rain. Amounts differ as the time period changes. Over 3 months is 18 to 21 inches, and over 6 months is 18 to 29 inches...all these take into account "precipitation, associated probabilities, and percent of normal precipitation needed to end or ameliorate drought." These figures are for the values at the end of July...and things have gotten drier since then.

I didn't realize the SE was in such a drought. They could've really benefitted from Emily moving more northward into the Carolinas.

I still think it will take a tropical system to bring Texas and Oklahoma initially out of our drought, and for a more "normal" fall weather pattern with plenty of rain. The tropics, especially the Gulf, have been really quiet so far though.

Yeah Georgia has been hit especially hard being in an exceptional drought there for awhile. Florida has been in a drought for years. Emily would have meant a lot for them.

If it stays quiet into the first week of September, then I'll worry. August starts to up tick pretty fast in to the 2nd half of the month, for now we are still pretty close to average.

Only Perkins up toward Stillwater got over an inch of rain. In Stillwater, the rain only amounted to .10. Between Stillwater and Perkins power lines were down on highway 177 and was closed for around 2 hours. A church had part of its roof blown off due to winds of around 70mph.

August 8, 2011 August 8, 2011 August 8, 2011 August 8, 2011


Oklahoma July Warmest on Record for U.S.

Grover Cleveland was serving his second term as President in 1895. Victoria was
the Queen of England and Will Rogers was still a teenager. It is also the year
that statewide average temperature records begin for the United States. There
have been 1399 months pass by since 1895. Multiply that number by 48 and you
have 67,152 months of temperature records for the contiguous states. How hot
was it in Oklahoma last month? Of those statewide average temperature records
for the 48 states, none has been hotter than July 2011 in Oklahoma.

According to data from the Oklahoma Mesonet, the statewide average temperature
during July came in at 89.1 degrees, more than 7 degrees above normal. High
temperatures alone were nearly 9 degrees above normal at 102.9 degrees. The
National Climatic Data Center's statewide average for July stands at 88.9
degrees with data still being collected. Both values shattered the country’s
previous record of 88.1 degrees held by another legendary hot month in
Oklahoma, July 1954.

http://ticker.mesonet.org/archive/20110808/July_statewide_averages.png

The extreme heat is being fueled by one of the worst short-term droughts in
state history. The drought’s beginnings date back to August 2010 but
intensified beginning in the fall under the influence of La Niņa. That climate
phenomenon, marked by cooler than normal water temperatures in the eastern
equatorial pacific, often means drier weather for the southern United States.
The statewide average precipitation total of 16.73 inches since October 1,
2010, is the driest on record at nearly 14 inches below normal. Parts of
southwestern Oklahoma have seen less than 6 inches of rain over that 10-month
period.

The loss of soil moisture and green vegetation has combined with the summer sun
to bake the state unmercifully. July was the hottest month in Oklahoma City’s
history, dating back to 1890. At 75 days through Sunday, Grandfield is quickly
approaching the state’s all-time record for days with highs above 100 degrees.
The record is 86 days, set at Hollis in the drought-fueled summer of 1956.
Unfortunately, the heat has only intensified during the first week of August.
The Mesonet has recorded a statewide average temperature of 92.1 degrees over
the month’s first seven days with an average high of 107 degrees and an average
low of 77 degrees. The state remains on course to record its warmest summer as
well. The statewide average temperature for the summer thus far is 87 degrees,
easily outpacing the current record of 85.2 degrees from 1934.

http://ticker.mesonet.org/archive/20110808/Mesonet_days_above_100.png

Unfortunately, widespread relief has yet to appear on the horizon. The latest
seasonal drought outlook from the National Weather Service’s Climate Prediction
Center (CPC) calls for drought to persist or intensify in Oklahoma through the
end of October. Farther out, the news is just as troubling. While the La Niņa
event faded in late spring, the CPC issued a La Niņa watch last week for
possible development once again this winter. The possibility of extending the
current drought further would be very bad news for a state already hit hard by
the heat and lack of rainfall.

http://www.koco.com/news/28800818/detail.html


NORMAN, Okla. -- An entomologist at Oklahoma State University says the record-setting heat and ongoing drought in Oklahoma is causing grasshoppers to move into urban areas in search of food.

Rick Grantham, who also is a professor at OSU, told The Norman Transcript that the lack of green vegetation in more rural areas has driven the insects into cities statewide.

"They eat green things, and green things are few and far between right now," Grantham said. "Your green lawn or garden is like a flashing cafe sign to them."

The insect population statewide is down this year, Grantham said, because of the drought and extreme heat, factors that bode well for the countless grasshoppers walking, flying or hopping around the rest of the state.

"A lot of insects eat grasshopper eggs before they hatch but we're not seeing a lot of other insects because of the conditions," Grantham said. "And grasshoppers do well in these conditions, so it's no surprise to see so many of them right now."

The month of July was the hottest month ever in Oklahoma based on records dating to 1895, according to the Oklahoma Climatological Survey, with an average daily temperature of 89.1 degrees

The western two-thirds of the state is in an exceptional drought, according the U.S. Drought Monitor, while most of the eastern one-third is in extreme drought.

We lost power about 8:00pm and it came back on around 4:00am. God Bless those OG&E guys and the work they do to restore power. We had about a half inch of rain in the rain gauge this morning.

So a nice though...chance of storms over at least the next 5 days. Let it soak in. The thought...the rain will probably just run off, but it's something. LOL

Tonight we do have a slight risk of severe storms in North Central OK for a complex developing in NE & KS right now. Also some severe storms erupting out in the TX Panhandle could move into Western OK.

Wednesday looks like a more widespread severe weather day with MCS activity moving through. Could see a more widespread damaging wind event, but nothing too high end the way it appears now.

SPC Outlook for Wednesday:

...SRN PLAINS ACROSS THE MS VALLEY...
AS A STRONG SHORT WAVE TROUGH CROSSES THE UPPER GREAT LAKES REGION
TODAY...THE DEEP-LAYER FRONTAL ZONE ASSOCIATED WITH THIS SYSTEM WILL
SETTLE FARTHER SOUTH ACROSS THE PLAINS AND MIDWEST. THE FRONT IS
FORECAST TO EXTEND FROM THE OH VALLEY WWD TO KS AND ADJACENT AREAS
OF THE CNTRL HIGH PLAINS BY EARLY WEDNESDAY. LIFT ACROSS THE WRN
EXTENSION OF THE FRONT WILL BE ENHANCED/STRENGTHENED EARLY IN THE
PERIOD BY BOTH NOCTURNAL MAXIMUM IN PLAINS LLJ AND QG FORCING AIDED
BY A LOW AMPLITUDE SHORT WAVE TROUGH SPREADING EAST ACROSS THE GREAT
PLAINS.

THUS...EXPECT A CONVECTIVE COMPLEX TO BE ONGOING WITHIN THE ZONE OF
ENHANCED MASS/MOISTURE TRANSPORT AND ISENTROPIC LIFT NEAR AND NORTH
OF FRONT ACROSS KS/NEB EARLY WEDNESDAY. THIS ACTIVITY COULD SERVE TO
REINFORCE THE DEEP-LAYER FRONTAL ZONE AS STRONG WARM SECTOR
DESTABILIZATION COMMENCED WITH HEATING OF THE DAY ACROSS OK/TX/AR.

LATEST GUIDANCE SUGGESTS THAT MCS ACTIVITY WILL PERSIST THROUGH THE
DAY AS THE UPPER LEVEL WAVE AND WEAK SURFACE REFLECTION ON THE FRONT
SPREAD EAST. ADDITIONAL STORMS ARE LIKELY TO DEVELOP NEAR THE FRONT
AND WITHIN THE WARM SECTOR THROUGH THE AFTERNOON AS CONVECTIVE
INHIBITION IS OVERCOME BY HEATING/MIXING AND PERSISTENT CONVERGENCE
NEAR FRONT AND RESIDUAL OUTFLOW BOUNDARIES. EXPECT A MIXED MODE OF
STORM TYPES ACROSS THE SLGT RISK AREA. THE POTENTIAL FOR A MORE
ORGANIZED FORWARD PROPAGATING MCS CAPABLE OF DAMAGING WINDS AND HAIL
MAY EVOLVE FROM NRN OK/SERN KS EAST ACROSS THE OZARKS TOWARD WRN TN
THROUGH THE DAY/EVENING WHERE A BELT OF STRONGER MID LEVEL FLOW IS
FORECAST TO EXIST COINCIDENT WITH THE LOW AMPLITUDE SHORT WAVE
TROUGH. TO THE SOUTH OF THESE AREAS...ON THE SRN FRINGE OF STRONGER
FLOW ALOFT...WEAKER EFFECTIVE SHEAR AND INVERTED-V PROFILES IN THE
STRONGLY HEATED BOUNDARY LAYER WILL SUPPORT MORE PULSE AND
MULTICELLULAR CONVECTION POSING MAINLY A DAMAGING WIND THREAT INTO
THE EVENING.

Fast forward a bit...all of this is based on 18Z GFS today, which I normally don't like the odd hour runs, but whatever. This is just a glance of what MAY happen. So here we go. Temps will bounce around a lot going forward. If you are in mostly cloudy and rainy conditions, you may be stuck in the 80s. If you have pure sun, 95 to 105 appears to be the rule. With moisture increasing and this new pattern setting up, the 110+ should be moderated a lot.

Thursday - Scattered strong to severe storms over most of Oklahoma. A complex could develop in the late evening in TX and Western OK that could bring very heavy rain and damaging winds.

Friday - Overnight MCS could still be on going with heavy rain rough west of I-35 and south of I-40 by early afternoon. Mostly dry elsewhere except for some sporadic popups.

Saturday - Isolated/Scattered storms around.

Sunday - Appears dry.

Monday - Slight chance of storms out west, but increasing risk of a complex developing in the late evening/overnight.

Tuesday - MCS will move east into Western OK early to around I-35 by Noon before dying out. Evening storms could fire along the outflow in Central OK and a new complex develop in KS/NW OK overnight.

Wednesday - Scattered storms in the Western half of OK during the first half of the day. Slight chance North and Northeast afternoon and evening.

Thursday 8/18 - Storms appear more widespread. Could have heavy rain in NE OK, light amounts back to the west...mainly along and north of I-40 early. Chances going up along I-44 late in the evening.

Friday 8/19 - Storms scattered, some light to moderate rain almost statewide.

Saturday 8/20 - Some isolated storms, not as much.

Sunday 8/21 - Chance of storms far NW OK, dry elsewhere.

Monday 8/22 - Chance of storms statewide.

Tuesday 8/23 - Chance of storms Central & West.

Wednesday 8/24 - Storms mostly northern half with a complex moving out of KS.

Thursday 8/25 - Chance of storms statewide.

VALID 101200Z - 111200Z

...THERE IS A SLGT RISK OF SVR TSTMS FROM SERN KS/ERN OK EWD INTO
THE SRN APPALACHIANS...

...SYNOPSIS...
ONLY MINOR CHANGES EXPECTED IN THE LARGE SCALE UPPER PATTERN THIS
PERIOD...WITH A FLAT RIDGE OVER THE S CENTRAL AND SWRN STATES...VERY
WEAK TROUGHING OVER THE NW...AND TROUGHING OVER THE EAST.

AT THE SURFACE...A BAROCLINIC ZONE IS FORECAST TO LIE NNW-SSE ALONG
THE HIGH PLAINS...AND THEN MORE EWD ACROSS THE SRN PLAINS/MID LOWER
MS VALLEY AND INTO THE SOUTHEAST. THIS BOUNDARY WILL COINCIDE WITH
A ZONE OF CONVECTIVE/LOW-END SEVERE POTENTIAL THROUGH THE PERIOD.

...SERN KS/ERN OK EWD INTO THE MID MS/TN VALLEYS...
SOMEWHAT DIFFICULT FORECAST ACROSS THIS REGION IN TERMS OF
DETAILS...AS WIDESPREAD CONVECTION ONGOING FROM NEB SWD INTO OK WILL
BE SHIFTING INTO THE SLIGHT RISK AREA EARLY IN THE PERIOD.
PRESUMING AMPLE DESTABILIZATION CAN OCCUR AHEAD OF THE LINGERING
CONVECTION...STORMS SHOULD REINTENSIFY DURING THE AFTERNOON -- AIDED
BY MODERATE WLY/WNWLY FLOW ALOFT.

STORMS SHOULD SHIFT EWD/ESEWD WITH TIME...MOVING ACROSS THE
MID/LOWER MS VALLEY INTO THE TN VALLEY...BEFORE WEAKENING DURING THE
EVENING INTO THE SRN APPALACHIANS. IN THE MEAN TIME...THREATS FOR
HAIL AND LOCALLY DAMAGING WINDS CAN BE EXPECTED ACROSS THE SLIGHT
RISK AREA.

CNTRL HIGH PLAINS...

...THERE IS A SLGT RISK OF SVR TSTMS OVER A PORTION OF THE SRN
PLAINS THROUGH LOWER MS VALLEY...

..SYNOPSIS...

THE ERN U.S. UPPER TROUGH WILL DEAMPLIFY SLIGHTLY ON THURSDAY WITH A

CONTINUATION OF THE PROGRESSIVE QUASI-ZONAL FLOW REGIME. SHORTWAVE
TROUGH NOW MOVING INTO SRN BRITISH COLUMBIA WILL REACH THE NRN HIGH
PLAINS THURSDAY AFTERNOON AND EVENING ACCOMPANIED BY A COLD FRONT.
QUASI-STATIONARY BAROCLINIC ZONE WILL PERSIST FROM THE SERN STATES
INTO THE SRN PLAINS OF EXTREME NRN TX OR SRN OK.

...SRN ROCKIES...SRN PLAINS THROUGH LOWER MS VALLEY AREAS...

STORMS WILL LIKELY ONCE AGAIN DEVELOP IN VICINITY OF CONVECTIVELY
REINFORCED BAROCLINIC ZONE FROM NRN TX OR OK EWD INTO THE LOWER MS
VALLEY REGION AS WELL AS OVER THE HIGHER TERRAIN OF NM AND SRN CO.
MUCH OF THIS REGION WILL REMAIN JUST SOUTH OF THE STRONGER FLOW
ALOFT...BUT STEEP LAPSE AND INVERTED-V PROFILES WILL SUPPORT A
THREAT OF ISOLATED DOWNBURSTS. OTHER STORMS MAY DEVELOP OVERNIGHT
ACROSS OK OR KS INTO THE LOWER MS VALLEY AS THE LLJ STRENGTHENS
RESULTING IN INCREASING LIFT NORTH OF THE BOUNDARY.
