Oklahoma Weather Discussion - February/March 2013

[venture]

NAM this evening has a line of storms develop over the TX PH Friday evening, moving into Western OK through the overnight Saturday into Sat AM. Then it has them die out west of I-35. Some scattered light precip Sat Afternoon before refiring the line in SE OK late Saturday.

[venture]

The evening GFS run is through this time period as well and is lining up pretty close to the NAM now. So the chances for any significant, widespread heavy rain appears all but dead. Best hope now is going to be with any storms that could dump enough over a smaller area.

[Bunty]

Yeah, the yr.no forecast has the precip reduced to hardly over .10 now.

[okc_coder]

That's too bad because we need the rain

[Anonymous.]

This system is certainly taking the high road track...

Basically cross your fingers that a substantial line of showers and thunderstorms sweeps across OK and that your yard gets a lucky downpour or two.

[OKCisOK4me]

We Canton rely on models two weeks out...

Slight Risk this evening for far western OK...

DAY 1 CONVECTIVE OUTLOOK CORR 1
NWS STORM PREDICTION CENTER NORMAN OK
1046 AM CST FRI MAR 08 2013

VALID 081630Z - 091200Z

...THERE IS A SLGT RISK OF SVR TSTMS PORTIONS TX PANHANDLE/WRN OK
AND TX SOUTH-PLAINS REGIONS...

CORRECTED FOR NDFD GRID GENERATION

...SYNOPSIS...
UPPER-AIR PATTERN ACROSS CONUS IS DOMINATED BY TWO PRIMARY CYCLONES
-- ONE OVER ATLC S OF NOVA SCOTIA WITH STG VORTICITY LOBE EXTENDING
WWD OVER MID-ATLC REGION...AND ANOTHER LOCATED OVER CHANNEL ISLANDS
AREA OFFSHORE SRN CA. AS MID-ATLC PERTURBATION MOVES
OFFSHORE...SYNOPTIC-SCALE RIDGING WILL SHIFT EWD ACROSS MS VALLEY TO
UPPER GREAT LAKES...LOWER OH VALLEY AND TN VALLEY REGIONS.
MEANWHILE...MAIN PAC LOW WILL TURN EWD ACROSS SRN CA...REACHING NEAR
AZ/NM BORDER BY END OF PERIOD. BROAD BELT OF CYCLONIC FLOW --
INCLUDING ROUGHLY 120-KT 250-MB JET MAX AND ELONGATED RIBBON OF
80-90 KT 500-MB WINDS -- WILL SHIFT EWD OVER PORTIONS SRN AZ AND NRN
MEX..IN STEP WITH PROGRESS OF CA CYCLONE. SMALLER MID-UPPER LEVEL
CIRCULATION IS EVIDENT IN MOISTURE CHANNEL IMAGERY OVER WRN ORE.
THIS FEATURE WILL WEAKEN...LOSING IDENTITY WITH TIME AS ITS
VORTICITY FIELD IS ENTRAINED INTO TRAILING PORTION OF CA
PERTURBATION. WEAK SHORTWAVE TROUGH IS EVIDENT IN SATELLITE IMAGERY
AND VWP/PROFILER DATA OVER SRN HIGH PLAINS ATTM...AND IS FCST TO
DEAMPLIFY AS IT EJECTS NEWD OVER MO/AR THIS EVENING.

AT SFC...15Z CHART SHOWED CYCLONE OVER SRN PORTION KS/CO BORDER
REGION...WITH SYNOPTIC WARM FRONT ENEWD ACROSS N-CENTRAL/NERN KS AND
WELL-DEFINED LEE TROUGH SSWWD OVER ERN NM. DRYLINE SHOULD BECOME
BETTER DEFINED TODAY FROM BIG-BEND REGION GENERALLY NNEWD ACROSS WRN
TX/OK PANHANDLES...RETREATING WWD SOMEWHAT OVERNIGHT. SECONDARY SFC
LOW...INITIALLY MORE CLOSELY RELATED TO MID-UPPER CYCLONE -- WAS
EVIDENT OVER SRN NV IN DRA-LAS AREA...WITH PAC COLD FRONT ARCHING
GENERALLY SWD OVER NRN BAJA. INTERMOUNTAIN LOW AND LEE LOW SHOULD
BEGIN TO MERGE OVER ERN CO AROUND END OF PERIOD. BY THAT TIME...PAC
COLD FRONT SHOULD CATCH UP TO RETREATED DRYLINE OVER PORTIONS TX
PANHANDLE/SOUTH-PLAINS AND PERMIAN BASIN REGIONS.

...CENTRAL/SRN HIGH PLAINS...
ISOLATED TSTMS ARE POSSIBLE BEFORE DARK NEAR DRYLINE...BUT
POTENTIALLY SUPERCELLULAR IN CHARACTER. SCATTERED TSTMS SHOULD FORM
AFTER DARK...INCREASING IN COVERAGE THROUGH MUCH OF OVERNIGHT HOURS
AS PAC COLD FRONT AND LARGE-SCALE ASCENT ALOFT CATCH UP TO DRYLINE.
GREATEST UNCONDITIONAL SVR THREAT IS OVER SRN HIGH PLAINS...BUT
ISOLATED SVR DEVELOPMENT IS POSSIBLE AS FAR N AS ERN CO/WRN KS INVOF
SFC LOW AND NEAR WARM FRONT.

AS LEADING/WEAK SHORTWAVE TROUGH EJECTS AWAY FROM REGION...
1. SUBTLE SHORTWAVE RIDGING WILL OCCUR...ACTING TO TEMPORARILY
REINFORCE ELEVATED MIXED LAYER THROUGH WEAK DAVA/DVM WHILE EWD
ADVECTION OF REMAINING EML CONTINUES.
2. ASSOCIATED CLOUD COVER WILL MOVE AWAY...LEAVING BROAD GAP OF
RELATIVELY CLEAR SKIES FOR REMAINDER DAYLIGHT HOURS PRIOR TO ARRIVAL
OF NEXT UVV PLUME...NOW EVIDENT IN VIS/IR IMAGERY OVER AZ.
3. DRYLINE WILL SHARPEN FROM COMBINATION OF MOIST ADVECTION FARTHER
E AND STRENGTHENING MIXING ALONG AND W OF BOUNDARY. W TX MESONET
DATA INDICATES LOW-50S F SFC DEW POINTS HAVE REACHED AREA BETWEEN
CDS-LBB. THOUGH MOISTENING VIA ADVECTION WILL BE OFFSET SOMEWHAT BY
HEATING/MIXING...EXPECT MID-UPPER 50S DEW POINTS IN NARROW CORRIDOR
E OF DRYLINE BY 00Z...FROM ERN PANHANDLES/WRN OK SWD.

MODIFIED RAOBS AND FCST SOUNDINGS SUGGEST 500-1000 J/KG MLCAPE
POSSIBLE E OF CAPROCK OVER SRN PLAINS...SOMEWHAT LESS OVER HIGHER
TERRAIN NEARER TO DRYLINE. BUOYANCY ALSO SHOULD WEAKEN NWD OVER WRN
KS WHERE MOISTURE WILL BE LESS. ROBUST MID-UPPER LIFT IS NOT FCST
TO REACH OUTLOOK AREA UNTIL OVERNIGHT -- LIKELY AFTER 03Z. AS
SUCH...EML-RELATED CAPPING SHOULD REMAIN STG...DELAYING ONSET OF
SUBSTANTIAL CONVECTION WHILE LIMITING BOTH ITS SWD EXTENT AND
DIURNAL COVERAGE. STILL...A FEW TSTMS MAY DEVELOP BEFORE DARK INVOF
DRYLINE...IN ENVIRONMENT CHARACTERIZED BY STRENGTHENING DEEP-LAYER
AND AT LEAST ADEQUATE LOW-LEVEL SHEAR FOR SUPERCELLS. EXPECT RISK
OF DAMAGING GUSTS AND HAIL WITH ANY SUCH TSTMS...SUPPORTED BY
INITIALLY HIGH LCL AND DEEP SUBCLOUD LAYER.

LOW-LEVEL MOISTURE...DEEP SHEAR AND LOW-LEVEL SHEAR EACH SHOULD
STRENGTHEN FROM LATE AFTN THROUGH EVENING AS MOIST ADVECTION
CONTINUES E OF DRYLINE...TROUGH ALOFT APCHS...AND BROAD/45-55 KT LLJ
TAKES SHAPE FROM W TX TO SERN NEB. RELATED HODOGRAPH ENLARGEMENT
SHOULD YIELD 250-450 J/KG EFFECTIVE SRH IN SUPPORT OF STORM-SCALE
ROTATION. DAMAGING GUSTS ARE POSSIBLE...THREAT DIMINISHING AFTER
ABOUT 06Z...WITH INCREASING HAIL RISK INTO EVENING. TORNADO
POTENTIAL...WHILE NON-ZERO...IS MITIGATED BY LACK OF ROBUST
MOISTURE...AND BY LIMITED TEMPORAL WINDOW BETWEEN EVENING LOWERING
OF LCL AND LOSS OF SFC-BASED EFFECTIVE INFLOW.

HRRR run showing the line of storms tonight at Midnight.

[Anonymous.]

Good destabilization occuring in the E TX pan handle to get the storms fired up nicely.

Hopefully they will get enough steam to make it to C OK.

[ou48A]

So is the Mike Morgan arctic blast or whatever you want to call it going to materialize or not?

I am thinking about planting some of my garden.

[Anonymous.]

Not sure what MM said, but looking @ the models I don't see significant cold air anytime soon. Unless something drastic changes in the long-term I think we may be saying goodbye to winter. I would say planting vegetation is a greenlight.

Thanks…… I will be planting some cool weather vegies soon.

Yeah the big Morgan Arctic Blast was on maybe 1 or 2 model runs...10 runs ago. LOL

MESOSCALE DISCUSSION 0252
NWS STORM PREDICTION CENTER NORMAN OK
0343 PM CST FRI MAR 08 2013

AREAS AFFECTED...WRN TX THROUGH THE CNTRL AND ERN TX AND OK
PANHANDLES AND EXTREME SWRN KS

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 082143Z - 090015Z

PROBABILITY OF WATCH ISSUANCE...60 PERCENT

SUMMARY...THUNDERSTORMS ARE EXPECTED TO DEVELOP EARLY THIS EVENING
ACROSS A PORTION OF WRN TX NWD INTO THE CNTRL TX PANHANDLE AND LATER
INTO PARTS OF THE OK PANHANDLE AND EXTREME SWRN KS. TIMING IS
SOMEWHAT UNCERTAIN...BUT INITIATION POTENTIAL IS EXPECTED TO
INCREASE SUBSTANTIALLY BETWEEN 23-01Z.

DISCUSSION...DRYLINE WAS LOCATED FROM THE CNTRL TX PANHANDLE NEAR
AMARILLO SWD THROUGH WRN TX. DOWNWARD MIXING OF STRONGER SWLY WINDS
ALOFT HAS RESULTED IN THE DRYLINE SURGING EWD THROUGH NRN PARTS OF
WRN TX AND THE TX PANHANDLE. HOWEVER...THIS BOUNDARY HAS RECENTLY
BECOME NEARLY STATIONARY...AND WILL LIKELY BEGIN TO RETREAT WWD AS
MIXING DIMINISHES WITH THE ONSET OF NOCTURNAL COOLING. CHARACTER OF
CLOUDS IN VISIBLE IMAGERY AND NAM PFCS SUGGEST THE BOUNDARY LAYER IS
STILL CAPPED EAST OF DRYLINE...WHERE MOIST AXIS WITH LOW-MID 50S
DEWPOINTS CONTINUE ADVECTING NWWD BENEATH AN EML. THE ATMOSPHERE
CONTINUES TO DESTABILIZE NWD WHERE AN AXIS OF 500-1000 J/KG MLCAPE
CURRENTLY EXISTS EAST OF THE CAP ROCK.

HIGH BASED STORMS DEVELOPING WITHIN ZONE OF DEEPER ASCENT AHEAD OF A
PROGRESSIVE SHORTWAVE TROUGH WILL CONTINUE SPREADING EWD THROUGH NM
INTO THE EARLY EVENING. THIS ZONE OF ASCENT ALONG WITH A PACIFIC
FRONT WILL EVENTUALLY INTERCEPT THE RETREATING DRYLINE AND MOIST
AXIS OVER WRN TX DURING THE EARLY EVENING. THESE PROCESSES WILL
CONTRIBUTE TO A WEAKENING CAP...AND THUNDERSTORMS WILL LIKELY
DEVELOP ALONG THE DRYLINE AND SUBSEQUENTLY SPREAD NEWD. SHEAR
PROFILES WILL INCREASE TO AOA 45 KT SUPPORTING THE POTENTIAL FOR
SUPERCELLS. MAIN THREATS WILL BE LARGE HAIL AND DAMAGING WIND GUSTS.
0-1 KM HODOGRAPHS WILL INCREASE IN SIZE THIS EVENING.
HOWEVER...TENDENCY FOR THE BOUNDARY LAYER TO STABILIZE AS THE LLJ
STRENGTHENS SHOULD KEEP TORNADO WINDOW RELATIVELY SMALL.

URGENT - IMMEDIATE BROADCAST REQUESTED
SEVERE THUNDERSTORM WATCH NUMBER 48
NWS STORM PREDICTION CENTER NORMAN OK
905 PM CDT FRI MAR 8 2013

THE NWS STORM PREDICTION CENTER HAS ISSUED A
SEVERE THUNDERSTORM WATCH FOR PORTIONS OF

FAR WESTERN OKLAHOMA
TEXAS PANHANDLE AND SOUTH PLAINS

EFFECTIVE THIS FRIDAY NIGHT AND SATURDAY MORNING FROM 905 PM
UNTIL 400 AM CDT.

WIDELY SCATTERED DAMAGING WINDS
ISOLATED WIND GUSTS TO 70 MPH POSSIBLE
WIDELY SCATTERED LARGE HAIL TO 1.5 INCHES IN DIAMETER

THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 70
STATUTE MILES EAST AND WEST OF A LINE FROM 50 MILES SOUTH
SOUTHEAST OF LUBBOCK TEXAS TO 50 MILES NORTH NORTHWEST OF GAGE
OKLAHOMA. FOR A COMPLETE DEPICTION OF THE WATCH SEE THE
ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU8).

REMEMBER...A SEVERE THUNDERSTORM WATCH MEANS CONDITIONS ARE
FAVORABLE FOR SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
AND POSSIBLE WARNINGS. SEVERE THUNDERSTORMS CAN AND OCCASIONALLY
DO PRODUCE TORNADOES.

DISCUSSION...BANDS OF TSTMS ARE LIKELY TO CONTINUE TO INCREASE AND
STEADILY SPREAD EAST-NORTHEASTWARD ACROSS THE TX PANHANDLE/TX SOUTH
PLAINS AND INTO WESTERN OK THROUGH THE LATE EVENING AND OVERNIGHT
HOURS. THIS DEVELOPMENT IS TIED TO INCREASING FORCING
ASCENT/VERTICAL SHEAR UNDER THE INITIAL INFLUENCE OF A SOUTHWEST
STATES UPPER TROUGH. WHILE VERTICAL SHEAR WILL BE STRONG...THE
THERMODYNAMIC ENVIRONMENT WILL REMAIN MARGINAL WITH MLCAPE OF ONLY A
FEW HUNDRED J/KG. EVEN SO...AT LEAST A MARGINAL THREAT FOR SEVERE
HAIL/WIND GUSTS WILL EXIST.

AVIATION...A FEW SEVERE THUNDERSTORMS WITH HAIL SURFACE AND ALOFT
TO 1.5 INCHES. EXTREME TURBULENCE AND SURFACE WIND GUSTS TO 60
KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 450. MEAN STORM
MOTION VECTOR 24050.

[venture]

Slight Risk today has been expanded into Central Oklahoma. It includes all areas east of a line from near Frederick to El Reno to Guthrie...and south of a line from Guthrie and due east. Highest tornado risk today is from South Central OK from Norman south into the DFW area.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1150 PM CST FRI MAR 08 2013

VALID 091200Z - 101200Z

...THERE IS A SLGT RISK OF SVR TSTMS TODAY AND TONIGHT ACROSS PARTS
OF THE SOUTHERN PLAINS...

...SYNOPSIS...
WAVES WITHIN SPLIT MID-LATITUDE WESTERLIES EXTENDING ACROSS NORTH
AMERICA STILL APPEAR LIKELY TO REMAIN OUT OF PHASE THROUGH THIS
FORECAST PERIOD. WITHIN ONE STREAM...MODELS SUGGEST THAT FLOW WILL
BECOME LESS AMPLIFIED ACROSS WESTERN INTO CENTRAL CANADA...AS A
SHORT WAVE IMPULSE FLATTENS RIDGING ACROSS BRITISH COLUMBIA. AS
THIS OCCURS...A DOWNSTREAM SHORT WAVE TROUGH...CURRENTLY DIGGING
ACROSS ALBERTA/SASKATCHEWAN...IS EXPECTED TO TURN EASTWARD ACROSS
MANITOBA INTO ONTARIO. AN IMPULSE SPLITTING OFF THIS FEATURE MAY
DIG INTO THE CENTRAL PLAINS AND INTERACT WITH A CLOSED LOW WITHIN A
SEPARATE STREAM TO THE SOUTH...EMERGING FROM THE FOUR CORNERS
REGION...AS SHORT WAVE RIDGING BUILDS ACROSS THE EASTERN PACIFIC
INTO THE PACIFIC NORTHWEST COAST. BUT VARIABILITY LINGERS AMONG THE
MODEL DATA CONCERNING THIS DEVELOPMENT...WHICH COULD FACTOR INTO
CONVECTIVE POTENTIAL ACROSS CENTRAL PLAINS DURING THIS PERIOD.
OTHERWISE...ANOTHER SHORT WAVE IMPULSE IS EXPECTED TO CONTINUE TO
DIG WITHIN LINGERING BROADER SCALE SOUTHERN STREAM TROUGHING ACROSS
THE SOUTHERN U.S./NORTHERN MEXICAN PLATEAU...WHILE UPPER RIDGING
SHARPENS DOWNSTREAM...ACROSS MUCH OF THE ATLANTIC SEABOARD.

COOL SURFACE RIDGING ASSOCIATED WITH THIS LATTER FEATURE IS EXPECTED
TO CONTINUE TO IMPACT MUCH OF THE NORTH CENTRAL AND EASTERN GULF OF
MEXICO...BUT A SUBSTANTIVE INFLUX OF MOISTURE IS ONGOING WITHIN A
RELATIVELY NARROW CORRIDOR FROM THE SOUTHWESTERN GULF OF MEXICO INTO
THE CENTRAL PLAINS/MID MISSOURI VALLEY REGION. THIS IS EXPECTED TO
CONTRIBUTE TO SUFFICIENT DESTABILIZATION FOR CONSIDERABLE
THUNDERSTORM ACTIVITY TODAY AHEAD OF A CONSOLIDATING COLD FRONT
ACROSS THE PLAINS. ACTIVITY IS LIKELY TO BE PRIMARILY SUPPORTED BY
FORCING ASSOCIATED WITH THE SOUTHERN STREAM IMPULSE...WHICH IS
FORECAST TO BE ACCOMPANIED BY A CYCLONIC BELT OF 70-90 KT 500 MB
FLOW...PROVIDING STRONG DEEP LAYER SHEAR...AND CONTRIBUTING TO A
RISK FOR SEVERE STORMS.

...SOUTHERN PLAINS...
ON THE NORTHWESTERN FRINGE OF STRONGER CAPPING ELEVATED MIXED LAYER
AIR...STORMS ARE EXPECTED TO BE ONGOING AT 09/12Z ACROSS PARTS OF
THE EASTERN TEXAS PANHANDLE AND WESTERN OKLAHOMA THROUGH MUCH OF
CENTRAL KANSAS...BEFORE DEVELOPING NORTHEASTWARD THROUGH THE
MID/LOWER MISSOURI VALLEY DURING THE DAY. SUBSTANTIAL DAYTIME
HEATING THEN APPEARS PROBABLE ALONG A SHARPENING DRYLINE ACROSS
PARTS OF SOUTHWESTERN OKLAHOMA...SOUTHWARD INTO THE PARTS OF THE
EDWARDS PLATEAU AND HILL COUNTRY OF TEXAS...AS SOUTHERLY LOW-LEVEL
FLOW MAINTAINS NORTHWARD ADVECTION OF LOWER 60S SURFACE DEW POINTS
ACROSS CENTRAL TEXAS INTO CENTRAL OKLAHOMA. GUIDANCE INDICATES AT
LEAST A NARROW CORRIDOR OF MODEST DESTABILIZATION BY PEAK AFTERNOON
HEATING...WITH MIXED LAYER CAPE REACHING 500-1000 J/KG. THIS
APPEARS LIKELY TO OCCUR COINCIDENT WITH THE MID-LEVEL LOW ADVANCING
EAST OF THE ROCKIES...AND THE TRAILING TROUGH AXIS GRADUALLY
PIVOTING INTO THE SOUTHERN PLAINS. ASSOCIATED FORCING WILL
CONTRIBUTE TO LATE AFTERNOON STORM INITIATION...INCLUDING A FEW
SUPERCELLS....AND PERHAPS AN EVOLVING SQUALL LINE.

LARGE HAIL AND DAMAGING WIND GUSTS WILL BE POSSIBLE IN STRONGEST
ACTIVITY. TORNADIC POTENTIAL IS A BIT MORE UNCERTAIN. MODELS
INDICATE STRONGEST SOUTHERLY 850 MB FLOW /40-50+ KT/ WILL TEND TO
DEVELOP NORTHEASTWARD AWAY FROM STRONGER BOUNDARY LAYER
DESTABILIZATION DURING THE DAY. BUT THEY ARE SUGGESTIVE OF AT LEAST
SOME OVERLAP OF BOUNDARY LAYER INSTABILITY AND SIZABLE CLOCKWISE
CURVED LOW-LEVEL HODOGRAPHS ACROSS PARTS OF NORTH CENTRAL TEXAS INTO
SOUTH CENTRAL OKLAHOMA...WHERE THE RISK FOR TORNADOES MAY BE
MAXIMIZED DURING THE LATE AFTERNOON AND EARLY EVENING HOURS.

MESOSCALE DISCUSSION 0260
NWS STORM PREDICTION CENTER NORMAN OK
1239 PM CST SAT MAR 09 2013

AREAS AFFECTED...WCNTRL THROUGH NWRN TX INTO SWRN AND SCNTRL OK

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 091839Z - 092045Z

PROBABILITY OF WATCH ISSUANCE...40 PERCENT

SUMMARY...THUNDERSTORMS ARE EXPECTED TO CONTINUE A GRADUAL INCREASE
IN COVERAGE...ORGANIZATION AND INTENSITY FROM WCNTRL-NWRN TX INTO
SWRN-SCNTRL OK. MAIN THREATS SHOULD BE ISOLATED DAMAGING WIND AND
LARGE HAIL. AREA IS BEING MONITORED FOR A POSSIBLE WW.

DISCUSSION...EARLY THIS AFTERNOON THUNDERSTORMS ARE DEVELOPING AND
INCREASING IN COVERAGE AND INTENSITY ALONG A PACIFIC COLD FRONT THAT
EXTENDS FROM WRN OK SWWD THROUGH WCNTRL AND SWRN TX. THE PRE-FRONTAL
WARM SECTOR HAS CLEARED OUT IN A NARROW CORRIDOR AHEAD OF THIS
BOUNDARY ACROSS SWRN OK WITH A BROADER AREA OF CLEARING FARTHER
SOUTH INTO NWRN AND WCNTRL TX. MID-LEVEL LAPSE RATES ARE WEAK AND
WILL TEND TO MITIGATE OVERALL CAPE MAGNITUDES WITH 800-1500 J/KG
LIKELY IN WARM SECTOR THIS AFTERNOON. STORMS SHOULD INCREASE IN
OVERALL INTENSITY AS THE BOUNDARY LAYER DESTABILIZES. LLJ WILL
GRADUALLY SHIFT EWD DURING THIS AFTERNOON WITH VEERING AND WEAKENING
LOW LEVEL FLOW EXPECTED ACROSS THE MORE UNSTABLE PORTION OF THE WARM
SECTOR. HOWEVER...EFFECTIVE SHEAR FROM 40-50 KT WILL REMAIN
SUPPORTIVE OF ORGANIZED STORMS INCLUDING A FEW BOWING SEGMENTS AND
SUPERCELLS CAPABLE OF PRIMARILY ISOLATED DAMAGING WIND AND LARGE
HAIL.

[okc_coder]

Looks like the weather is going to turn nice around mid-week... time to open the windows for some fresh air in the house.

[silvergrove]

Heard mike Morgan yesterday say there was an arctic blast coming in 8 to 10 days.

¯\_(ツ)_/¯

[Anonymous.]

Quiet weather until about the end of this weekend and into next week. At this time it looks like rain.

[venture]

So forecast for late weekend and early next week has a chance of storms. Instability will start to increase over the weekend. Storms should begin to break out in the late Afternoon mainly in the area from I-35 west to about Clinton to Altus line. GFS putting CAPE values around 1000-1250 j/kg and LI values will be in the -4 to -6 range over that area. All pretty decent for this time of year to get a few strong storms. Temps look to be well into the 70s that day so heat won't be an issue. Dewpoints well into the mid to upper 50s as well, so we'll have moisture around. Upper winds look fairly linear but some twist to them (SSW at surface to WSW higher up). Severe risk right now I would say is pretty marginal to slight.

Storms increase overnight and move east. Might see some redevelopment over SW OK Monday, but it won't last. Monday looks like the main show with this system in the Plains and it will be mainly from Extreme SE OK through NE TX and back to the SE towards Austin. Pretty high instabilities down in that area and could see the first decent severe weather day for the Plains this year.

Looking farther down the road. Some storms possible Late Saturday the 23rd through Sunday the 24th. This could be a late show west, overnight central, and during the day East.

Winter precip wise...not seeing any for the rest of the month at this point. So we have probably turned the corner unless something changes quickly. Which it can.

[Plutonic Panda]

Well, this sucks! This isn't really Feb. or March related weather, but thought I'd post it anyways. Long-range forecasts predict dry, hot summer for Oklahoma | News OK

[Anonymous.]

Chances of rain this coming weekend to next week look to be diminishing somewhat on current model runs.

Long-term at this time is showing a possible return of old man winter sometime around the 24th.

[okcboomer]

Heard mike Morgan yesterday say there was an arctic blast coming in 8 to 10 days.

This is why people can't take the local weathermen seriously.
