venture 06-13-2014, 03:03 AM Slight Risk tomorrow over the NW 1/3rd of Oklahoma. NW OK is under a 15% hatched area.
...TX/OK PANHANDLES INTO WRN OK...
STRONG HEATING WILL OCCUR NEAR THE DRYLINE...WITH FAVORABLE
CONFLUENT LOW-LEVEL FLOW. CAPPING WILL BE ERASED DURING THE PEAK
HEATING HOURS WITH AT LEAST ISOLATED THUNDERSTORMS DEVELOPING.
VEERING WIND PROFILES WITH HEIGHT WILL FAVOR SOMEWHAT
HIGH-BASED...SLOW-MOVING SUPERCELLS CAPABLE OF LARGE HAIL AND
LOCALLY DAMAGING OUTFLOW. THE STRONGEST CELLS MAY PERSIST INTO THE
EVENING EVEN AS CAPPING INCREASES...AIDED BY THE INTENSE LOW-LEVEL
JET.
venture 06-14-2014, 01:09 AM Slight Risk today is roughly west of a line from Ponca City - Weatherford - Altus. Area includes 5% tornado area, 15% wind, and 15% hail area - far NW OK is also hatched for very large hail.
...WRN KS THROUGH WRN OK AND WRN TX...
THE ATMOSPHERE IS EXPECTED TO BECOME STRONGLY UNSTABLE IN THIS
REGION AS VERY STEEP LAPSE RATES OVERSPREAD MOIST AXIS. WIDELY
SCATTERED STORMS ARE EXPECTED TO DEVELOP BY MID-LATE AFTERNOON
WITHIN ZONE OF DEEP MIXING ALONG THE DRYLINE. WIND PROFILES WILL
STRENGTHEN AHEAD OF A SHORTWAVE TROUGH WITH EFFECTIVE SHEAR FROM
40-45 KT LIKELY. SUPERCELLS CAPABLE OF VERY LARGE HAIL WILL BE THE
MAIN THREAT...THOUGH ISOLATED TORNADOES WILL ALSO BE
POSSIBLE...ESPECIALLY ACROSS WRN KS.
venture 06-14-2014, 01:37 PM Threat remains today. Big hail, damaging winds and a couple tornadoes possibles.
...WRN PARTS OF OK/TX THIS AFTERNOON/EVENING...
STRENGTHENING DRYLINE CIRCULATIONS OWING TO STRONG HEATING WITHIN
THE DRY AIR WILL BE THE PRIMARY FORCING MECHANISM THROUGH THE PEAK
OF THE DIURNAL HEATING CYCLE. AND LATEST MODEL GUIDANCE SUGGESTS
THAT THIS SHOULD BE SUFFICIENT TO INITIATE ISOLATED STORMS BY LATE
AFTERNOON OR EARLY EVENING WITHIN AN ENVIRONMENT CHARACTERIZED BY
MLCAPE OF 2000-3000 J/KG AND 30-40 KT OF DEEP-LAYER SHEAR. AS
SUCH...SUPERCELLS APPEAR LIKELY GIVEN STORM INITIATION WITH A RISK
FOR VERY LARGE HAIL...LOCALLY DAMAGING WINDS...AND PERHAPS A TORNADO
OR TWO.
Slight risk tomorrow expanded through W OK.
...SOUTH-CENTRAL PLAINS/SOUTHERN HIGH PLAINS...
WHILE THE EXTENT OF DEEP CONVECTIVE DEVELOPMENT IS UNCERTAIN IN THE
PRESENCE OF MODEST LARGE-SCALE INFLUENCES...IT APPEARS THAT A LEAST
A CONDITIONAL SURFACE-BASED SEVERE RISK WILL BE POSSIBLE ACROSS THE
SOUTH-CENTRAL PLAINS SUNDAY LATE AFTERNOON INTO EVENING. THIS WILL
MAINLY BE IN VICINITY OF THE WEAKENING FRONTAL SEGMENT THAT WILL
GENERALLY STALL IN A SOUTHWEST-NORTHEAST ORIENTATION EARLY IN THE
DAY. ESPECIALLY GIVEN STRONG HEATING NEAR/WEST OF A WEAK SURFACE
LOW/DRYLINE...THE RELATIVELY GREATEST /ALBEIT STILL UNCERTAIN/
POTENTIAL FOR DEEP CONVECTIVE INITIATION MAY BE NEAR A SURFACE
TRIPLE POINT ACROSS THE TX PANHANDLE INTO WESTERN OK. AMPLE
INSTABILITY WILL BE IN PLACE WITHIN THE NEARBY WARM SECTOR WITH
UPWARDS OF 3500-4000 J/KG OF MLCAPE POSSIBLE BY PEAK HEATING...WITH
SUFFICIENT DEEP-LAYER SHEAR OF 35-40 KT /MAXIMIZED NEAR THE FRONTAL
ZONE/ FOR A FEW SUPERCELLS...PROVIDED THE DEVELOPMENT/SUSTENANCE OF
THUNDERSTORMS.
FARTHER SOUTHWEST...OTHER STRONG/POSSIBLY SEVERE TSTMS MAY BE
POSSIBLE ACROSS OTHER PARTS OF WEST/SOUTHWEST TX WITHIN A MODERATELY
UNSTABLE BUT MODESTLY FORCED/WEAKLY SHEARED REGIME.
venture 06-14-2014, 08:30 PM Most of the development in the PH has collapsed so far.

PROBABILITY OF WATCH ISSUANCE...60 PERCENT
SUMMARY...SEVERAL STRONG TO SEVERE THUNDERSTORMS CAPABLE OF ISOLATED
LARGE HAIL AND SEVERE WIND GUSTS MAY DEVELOP THIS EVENING OVER
W-CNTRL AND SWRN KS. A CONDITIONAL SEVERE THREAT...ALBEIT LOWER
PROBABILITY...EXISTS OVER NWRN PORTIONS OF OK AND THE NERN TX

DISCUSSION...RADAR MOSAIC AND SATELLITE IMAGERY SHOW MID-LEVEL
CONVECTION OVER SERN CO INTO FAR NERN NM WHICH IS LIKELY ASSOCIATED
WITH THE LEADING EDGE TO A BAND OF MID-LEVEL ASCENT VIA THE CO
SHORTWAVE TROUGH. THE MID-LEVEL ASCENT/CONVECTION IS LOCATED
OVERTOP A VERY DRY LOW-LEVEL AIRMASS TO THE W OF A RETREATING
DRYLINE EXTENDING FROM HUTCHINSON COUNTY TX NWD AND EQUIDISTANT
BETWEEN GCK AND DDC. AS THE CO SHORTWAVE TROUGH EJECTS EWD INTO THE
CNTRL HIGH PLAINS THIS EVENING...EXPECTING THE LOBE OF ASCENT/ONSET
OF MID-LEVEL HEIGHT FALLS TO OVERTAKE THE DRYLINE IN THE 02-03Z
PERIOD. ONCE THIS OCCURS...STORM DEVELOPMENT WILL PROBABLY OCCUR ON
AT LEAST AN ISOLATED BASIS AND FAVORABLY TIME WITH A RAPID INCREASE
IN A SLY LLJ /50+ KT/ INTO W-CNTRL AND SWRN KS BY MID-EVENING.
THOUGH STORM DEVELOPMENT IS THE PRIMARY UNCERTAINTY...AN ATTENDANT
LARGE TO VERY LARGE HAIL THREAT AND ACCOMPANYING SEVERE WIND GUST
RISK WOULD ENSUE IF STORMS MATURE AND ARE SUSTAINED.

GIVEN THE TENDENCY FOR MIDLEVEL HEIGHT RISES AND THE WEAKENING
SYNOPTIC FRONT...SURFACE-BASED STORM INITIATION AND SUSTENANCE
REMAINS HIGHLY UNCERTAIN THROUGH THE DAYLIGHT HOURS. LATEST MODEL
GUIDANCE SUGGESTS THE MOST PROBABLE LOCATION FOR LATE

Dessert Fox 06-15-2014, 05:17 PM I saw that next week we might be seeing a tropical-like system, is this still the case?

Putting in some overtime at work as well right now to help pay the bills. Lol. You are welcome of course.
Slight risk today for central to northeast Oklahoma. Main risks big hail and wind... If anything forms. 5% tornado area as well north of I 40 but nothing significant.
Bunty 06-15-2014, 11:12 PM I saw that next week we might be seeing a tropical-like system, is this still the case?
Probably so, but not real heavy. The Norwegian Meteorological Institute has Oklahoma City forecast to get 1.31" of rain Thursday night and Friday morning.

venture 06-16-2014, 03:05 AM I saw that next week we might be seeing a tropical-like system, is this still the case?
It appears most models have backed away from any tropical systems developing this week. The NAVGEM is one of the hold outs of a weak low developing in the Eastern Gulf and then just meander around in the Central Gulf.
Rain chances on Thurs/Fri still are there but aren't tropical related.
Anonymous. 06-16-2014, 09:02 AM Wed-Fri this week looks interesting. Mostly Thurs. and Fri. for main body of OK.
Looking long-range into the following week. Looks like we may slip into another pattern of MCS's and good rain chances.

I'm perfectly fine with a down year for tornados here in Oklahoma. Crazy that north central California has seen more warnings than our whole state!

venture 06-17-2014, 05:26 PM Looking at through the rest of the month on the GFS a nice sight...no death ridge setting up. Fairly active pattern will remain with isolated changes of storms every so often and the occasional storm complex marching through. Might have a ridge build in by the first week of July, but even then it doesn't look to be substantial yet.
Hard to pin point exact storm chances per day since there will be a lot of people in one area staying sunny and dry while another area will be dodging golf balls from the sky. Instability really doesn't look like an issue at all either...it'll come down to have the proper triggers and place and breaking the cap. Next Tuesday could be interesting and then maybe some heavy rain next Thurs/Friday (not this week).
venture 06-18-2014, 03:09 AM Day 1 has a slight risk today over Western OK for very large hail.
...WRN KS SWD THROUGH OK/TX PANHANDLES AND WEST/SOUTHWEST TX...
MODERATE TO VERY STRONG INSTABILITY IS EXPECTED INVOF THE DRY LINE
EXTENDING SWD FROM WRN KS THROUGH THE OK/TX PANHANDLES...WEST TX TO
THE TX BIG BEND REGION. THIS COMBINED WITH PW VALUES INCREASING TO
1.25-1.5 INCHES AND STEEP MIDLEVEL LAPSE RATES WILL SUPPORT MODERATE
TO VERY STRONG INSTABILITY THIS AFTERNOON. EFFECTIVE BULK SHEAR
SHOULD GENERALLY RANGE FROM 30-40 KT...THOUGH VALUES UP TO 45 KT
WILL BE POSSIBLE FROM THE TX PANHANDLE INTO WEST TX. ASCENT ALONG
THE DRY LINE AND A MIDLEVEL IMPULSE MOVING ACROSS THIS REGION DURING
PEAK HEATING SUGGEST TSTMS SHOULD DEVELOP FORM WRN KS SWD THROUGH
WEST AND SOUTHWEST TX. VERY LARGE HAIL WILL BE POSSIBLE WITH SOME
OF THE STORMS IN ADDITION TO A THREAT FOR DAMAGING WIND GUSTS.
Day 2 Slight Risk in NW OK
...KS SWD INTO WRN TX...
A WEAK BOUNDARY IS EXPECTED TO MIX OUT DURING THE DAY ACROSS KS WITH
A DRYLINE INTO WRN TX. HEATING AND SELY SURFACE WINDS WILL MAINTAIN
MODERATE INSTABILITY LEVELS WITH LOW TO MID 60S F DEWPOINTS.
THERMODYNAMIC PROFILES WILL FAVOR ROBUST UPDRAFTS CAPABLE OF LARGE
HAIL AND WEAKLY VEERING WINDS WITH HEIGHT MAY SUPPORT A FEW
SUPERCELLS ESPECIALLY OVER KS. SHEAR DECREASES WITH SWD EXTENT INTO

SUMMARY...CONVECTIVE INITIATION IS EXPECTED WITHIN THE NEXT HOUR OR
TWO ACROSS THE SRN HIGH PLAINS. SCATTERED STRONG TO SVR TSTMS ARE
EXPECTED WITH ONE OR MORE WATCHES POSSIBLY NEEDED TO COVER THE
THREAT. PRIMARY SVR THREAT WILL LIKELY BE SVR HAIL WITH A SECONDARY
THREAT OF DAMAGING WINDS.
DISCUSSION...VISIBLE SATELLITE IMAGERY SHOWS INCREASED CU ACROSS SW
KS AND ALONG THE TX/NM BORDER E OF CVS. MID/UPPER LEVEL CLOUDINESS
MAY BE OBSCURING SOME CU AROUND AMA AS WELL. DIURNAL HEATING
CONTINUES TO DESTABILIZE AN ENVIRONMENT CHARACTERIZED BY DEWPOINTS
IN THE LOW TO MID 60S AND STEEP MID-LEVEL LAPSE RATES. SURFACE
ANALYSIS REVEALS A DUAL DRYLINE STRUCTURE WITH THE LEADING DRYLINE
EXTENDING FROM SW KS SSWWD ACROSS THE OK AND TX PANHANDLES AND TX S
PLAINS. THE SECONDARY DRYLINE EXTENDS SWD FROM A LOW IN SE CO ACROSS
FAR WRN NM. TSTM DEVELOPMENT IS MOST LIKELY ALONG THE LEADING
DRYLINE BUT SOME ADDITIONAL DEVELOPMENT IS POSSIBLE ALONG THE
SECONDARY DRYLINE. SATELLITE IMAGERY ALSO REVEALS A SHORTWAVE TROUGH
OVER NE NM MOVING INTO SW KS.
OBJECTIVE ANALYSIS ESTIMATES MLCAPE FROM 1500 TO 2500 J PER KG ALONG
AND AHEAD OF THE LEADING DRYLINE. LOW-LEVEL SWLY FLOW IS GENERALLY
AROUND 10 TO 15 KT WITH REGIONAL VAD WIND PROFILES SUGGESTING
MID-LEVEL SWLY FLOW AROUND 20 KT. THE RESULT IS A WEAKLY SHEARED
PROFILE. HOWEVER...BULK SHEAR WILL GRADUALLY INCREASE THROUGHOUT THE
AFTERNOON AND INTO THE EVENING WITH STORMS EXPECTED TO GRADUALLY
INTENSIFY AS THEY MOVE EWD.
SCATTERED STRONG TO SEVERE TSTMS ARE EXPECTED WITH THE PRIMARY
THREAT OF SEVERE HAIL. SOME DAMAGING WINDS ARE ALSO POSSIBLE. ONE OR
MORE WATCHES MAY BE NEEDED TO ADDRESS THIS SVR THREAT.

THE NORTHERN PLAINS AND CENTRAL CANADIAN/U.S. BORDER AREA. TO THE
EAST AND SOUTH OF THIS INCREASINGLY NEGATIVE TILTED FEATURE...MODEST
CYCLONIC MID/UPPER FLOW WILL OVERSPREAD MUCH OF THE LOWER NORTHERN

TROUGHING ACROSS PARTS OF THE EASTERN DAKOTAS...AS WELL AS ACROSS
PARTS OF THE CENTRAL PLAINS INTO SOUTHERN HIGH PLAINS.
ACROSS PARTS OF THE MID MISSOURI INTO UPPER MISSISSIPPI VALLEY...
THE SURFACE TROUGH LIKELY WILL BE PRECEDED BY CONSIDERABLE EARLY
PERIOD CONVECTION...AND REMNANT OUTFLOW WILL CONTRIBUTE TO
UNCERTAINTY WITH REGARD TO SUBSEQUENT DESTABILIZATION AND FOCUS FOR
AFTERNOON EVENING STORM DEVELOPMENT. FURTHER COMPLICATING SEVERE
WEATHER POTENTIAL...MODELS SUGGEST THAT STRONGER SOUTHERLY 850 MB
FLOW /ON THE 30 KT/ AHEAD OF THE SURFACE TROUGH AT THE OUTSET OF THE
PERIOD WILL GENERALLY WEAKEN DURING THE DAY SOUTH OF THE
INTERNATIONAL BORDER AREA. AND MID-LEVEL LAPSE RATES ARE IN THE

NORTHEASTWARD INTO WESTERN AND CENTRAL IOWA BY EARLY AFTERNOON...AND
IN A CORRIDOR ACROSS EASTERN NORTH DAKOTA AND ADJACENT SOUTH
DAKOTA/MINNESOTA BY LATE THIS AFTERNOON OR EARLY EVENING. THIS

Were you not around here in summer of 2012 when everyone got their ridge of death? The most I want is a standard Oklahoma summer. So far, so good, since the 100s haven't returned already too soon and it's not bone dry. But wait for the 4th of July.
venture 06-22-2014, 10:22 AM Slight Risk through tonight for the NW 1/4th of Oklahoma.
...PLAINS AREA THROUGH EARLY TONIGHT...
A SURFACE COLD FRONT FROM NW MN TO NE CO THIS MORNING WILL MOVE
SWD/SEWD THROUGH THE AFTERNOON IN ASSOCIATION WITH SUBTLE SPEED
MAXIMA PROGRESSING EWD FROM THE CENTRAL ROCKIES...AND WILL PROVIDE A
FOCUS FOR STRONG/SEVERE THUNDERSTORM DEVELOPMENT. IN THE WAKE OF
THE MORNING MCS OVER THE MID MO VALLEY...MODERATE-STRONG BUOYANCY
WILL DEVELOP BY AFTERNOON FROM CENTRAL NEB SWWD ACROSS KS TO THE TX
PANHANDLE. WLY MID-UPPER FLOW AND WEAK BUT VEERING WINDS WITH
HEIGHT IN THE LOW LEVELS WILL RESULT IN EFFECTIVE BULK SHEAR OF
30-35 KT...WHICH WILL FAVOR ORGANIZED CLUSTERS AND SOME SUPERCELL
STRUCTURES. MLCAPE OF 2000-3000 J/KG AND MIDLEVEL LAPSE RATES OF
7-8 C/KM WILL FAVOR LARGE HAIL PRODUCTION WITH ANY
SUPERCELLS...WHILE CELL MERGERS ALONG THE FRONT WILL LEAD TO UPSCALE
GROWTH INTO CLUSTERS BY THIS EVENING. THE MOST CONCENTRATED RISK
AREA FOR DAMAGING WINDS WILL BE THIS EVENING INVOF SW KS...WHILE
SOME RISK WILL PERSIST INTO EARLY TONIGHT ACROSS CENTRAL KS/NW OK.

Don't say that in a bar in the country that is frequently visited by farmers. They probably don't take to kindly to drought lovers. lol

I suspect he's just trying to get our dander up, but what a seriously stupid thing to say.
bchris02 06-22-2014, 03:32 PM I hope this summer is like last year where there is ample rainfall to keep things green all summer long without a real "ridge of death."

Too dry...south central/southeast TX was great last week. Around Lagrange and points south. 90 degrees by around 10 am, then on the coast, about 88-ish, with 60+ humidity.
We were working for an afternoon to restore an old family cemetery that dates from the 1870s in SE TX and it was almost "fainting hot".
Gulf waters were around 87 degrees. Nothing at all bad about any of that except I wasn't retired and living near the beach. :) I've been down there before when the waters were around 91 and that was almost too hot to swim in. Almost. ;)

AREAS AFFECTED...SWRN/S CNTRL KANSAS...NWRN OK...THE TEXAS
PANHANDLE...NERN NEW MEXICO
CONCERNING...SEVERE THUNDERSTORM WATCH 346 (http://www.spc.noaa.gov/products/watch/ww0346.html)...347 (http://www.spc.noaa.gov/products/watch/ww0347.html)...
VALID 230119Z - 230245Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
346...347...CONTINUES.
SUMMARY...POTENTIAL EXISTS FOR THE CONTINUED EVOLUTION OF AN
INCREASINGLY ORGANIZED MESOSCALE CONVECTIVE SYSTEM ACCOMPANIED BY
THE RISK FOR STRONG/DAMAGING WIND GUSTS ACROSS THE SOUTH CENTRAL
HIGH PLAINS THROUGH 03-06Z. A NEW WW WILL LIKELY BE ISSUED BY THE
CURRENTLY SCHEDULED 03Z EXPIRATION OF WWS 346 AND 347.
DISCUSSION...MERGING CONVECTIVE OUTFLOWS HAVE CONTRIBUTED TO NEW
INTENSE CONVECTIVE DEVELOPMENT NEAR GARDEN CITY...SOUTHWARD TOWARD
THE ELKHART AREA. STRONGEST ACTIVITY IS BECOMING INCREASINGLY
FOCUSED ALONG THE GUST FRONT ASSOCIATED WITH THE MORE PROMINENT COLD
POOL SURGING OUT OF THE COLORADO HIGH PLAINS. ADDITIONAL STRONG TO
SEVERE STORM DEVELOPMENT IS EXPECTED INTO THE 03-06Z TIME FRAME...AS
IT CONTINUES SOUTHEASTWARD/SOUTHWARD ACROSS THE PANHANDLE REGION AND
NORTHEAST NEW MEXICO.
OTHERWISE...CONTINUED UPSCALE CONVECTIVE GROWTH APPEARS LIKELY
DURING THE NEXT SEVERAL HOURS...AS THE PRE-CONVECTIVE ENVIRONMENT
REMAINS MODERATELY UNSTABLE IN THE PRESENCE OF SUFFICIENT VERTICAL
SHEAR. THIS PROCESS MAY BE AIDED BY SOUTHERLY LOW-LEVEL JET
INTENSIFICATION ABOVE THE DECOUPLING BOUNDARY LAYER...WHICH MAY
FOCUS THE MOST VIGOROUS CONVECTION AND HIGHEST PROBABILITIES FOR
STRONG...POTENTIALLY DAMAGING...WIND GUSTS ACROSS THE EASTERN TEXAS
PANHANDLE INTO WESTERN OKLAHOMA.

Bobby821 06-23-2014, 08:41 AM What do our rain chances look like for the rest of this week? any more good soaking rains like we had last night?

That's stupid.
ou48A 06-23-2014, 09:06 AM Hope we get more rain…..
Once again Norman missed out compared to OKC.
At 6.9 inches of rain Norman’s 90 day rain total is significantly behind most of the OKC which is 11.8 to 14.6…….
Norman did get .58 and that was enough rain to water in my fertilizer.
