Thread: Oklahoma Weather Discussion - January/February 2012

  1. Default Re: Oklahoma Weather Discussion - January/February 2012

    Sorry new work schedule has things messed up for me. Should be settling down a bit now. Tornado Watches through most of Central KS now just across the border. Might see this extend south into Oklahoma, but it looks to be mostly Eastern OK at this point. Also don't confuse severe weather chances with your typical understanding of weather probabilities. There can still be significant severe weather in "slight" risks.

    Also I'll get the March severe weather thread remade here in a minute to make sure we have appropriate information in the initial post.

    Things are starting to pop in Woods County. Could go severe soon. We'll need to wait and see if the line zips south now or waits. HRRR indicates things will hold off until it gets east of I-35 and then develop south.

    AREAS AFFECTED...S-CNTRL/SERN KS...N-CNTRL OK

    CONCERNING...TORNADO WATCH 40...

    VALID 290116Z - 290245Z

    THE SEVERE WEATHER THREAT FOR TORNADO WATCH 40 CONTINUES.

    INITIAL DISCRETE SUPERCELL WITH A HISTORY OF PERIODIC BRIEF TORNADO
    TOUCHDOWNS WILL BE THE PRIMARY NEAR-TERM SEVERE THREAT INVOF
    RENO/HARVEY/MCPHERSON COUNTIES KS. ADDITIONAL TSTM DEVELOPMENT
    APPEARS TO BE UNDERWAY AS COLD FRONT HAS OVERTAKEN THE DRYLINE INTO
    NWRN OK. ALTHOUGH CONVECTION SHOULD TRANSITION TO A LARGELY LINEAR
    MODE...VERY STRONG SHEAR WILL BE FAVORABLE FOR AN INCREASING RISK OF
    DAMAGING WINDS...WITH PERHAPS AN ADDITIONAL TORNADO OR TWO. A NEW WW
    MAY BE NEEDED FOR PARTS OF OK.

    01Z SURFACE ANALYSIS INDICATES THE PACIFIC COLD FRONT HAS OVERTAKEN
    THE DRYLINE ACROSS CNTRL KS INTO FAR NWRN OK...RESULTING IN A
    SUBSTANTIAL INCREASE IN CONVERGENCE. THIS HAS YIELDED A RAPID
    INCREASE IN TSTM COVERAGE ALONG THE BOUNDARY. MEANWHILE...A COUPLE
    OF DISCRETE STORMS HAVE PERSISTED AHEAD OF THE DRYLINE INVOF HUT.
    ALTHOUGH THE 00Z OUN RAOB WAS QUITE CAPPED...MODIFIED TOP RAOB
    SUGGESTS INSTABILITY IS WEAK /MLCAPE NEAR 500 J/KG/ BUT SUFFICIENT
    FOR TORNADO AND DAMAGING WIND THREATS GIVEN PRESENCE OF EFFECTIVE
    SRH AOA 400 M2/S2. CONTINUED BOUNDARY LAYER MOIST ADVECTION SHOULD
    SUPPORT THESE RISKS WITHIN ONE OR MORE PROBABLE LINE-SEGMENTS
    PROPAGATING QUICKLY E/SEWD THIS EVENING.

    This includes the North and East metro areas. Could argue the watch polygon does cover the northern half of Oklahoma County, but doesn't matter...in and close to the watch area and all that jazz. Based on the counties added it seems that the general feeling is storms will develop south the more east they get.



    URGENT - IMMEDIATE BROADCAST REQUESTED
    TORNADO WATCH NUMBER 41
    NWS STORM PREDICTION CENTER NORMAN OK
    810 PM CST TUE FEB 28 2012

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

    EASTERN KANSAS
    NORTH CENTRAL AND NORTHEAST OKLAHOMA

    EFFECTIVE THIS TUESDAY NIGHT AND WEDNESDAY MORNING FROM 810 PM
    UNTIL 100 AM CST.

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

    THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 70 STATUTE
    MILES EAST AND WEST OF A LINE FROM 55 MILES NORTH NORTHWEST OF
    TOPEKA KANSAS TO 15 MILES SOUTHEAST OF CHANDLER OKLAHOMA. FOR A
    COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE
    UPDATE (WOUS64 KWNS WOU1).

    REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
    TORNADOES AND 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.

    OTHER WATCH INFORMATION...THIS TORNADO WATCH REPLACES TORNADO
    WATCH NUMBER 40. WATCH NUMBER 40 WILL NOT BE IN EFFECT AFTER 810
    PM CST. CONTINUE...WW 39...

    DISCUSSION...THE EARLIER DRYLINE SUPERCELLS IN S CENTRAL KS ARE NOW
    APPROACHING NE KS...AND MAY PERSIST FOR ANOTHER COUPLE OF HOURS AS
    THE LOW LEVELS MOISTEN FROM S TO N. FARTHER W/SW...CONVECTION
    CONTINUES TO INCREASE/BACKBUILD AS THE COLD FRONT OVERTAKES THE
    DRYLINE AND THE MIDLEVEL TROUGH EJECTS ENEWD OVER KS. ADDITIONAL
    LOW-LEVEL MOISTENING ACROSS OK/SE KS WILL SUPPORT CONVECTION ROOTED
    AT OR VERY NEAR THE SURFACE...IN AN ENVIRONMENT WITH EFFECTIVE SRH
    OF 400-700 M2/S2. THE QUASI-LINEAR CONVECTIVE MODE AND MODEST
    INSTABILITY SUGGEST THAT THE HAIL RISK WILL BE TEMPERED
    SOMEWHAT...BUT SEMI-DISCRETE CELLS IN THE LINE WILL POSE A RISK FOR
    DAMAGING GUSTS AND PERHAPS A COUPLE OF TORNADOES.

    AVIATION...TORNADOES AND 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 27040.

    Development seems to be building further south. Looks as though we will be getting it here in Tulsa.

  8. Default Re: Oklahoma Weather Discussion - January/February 2012

    Line of storms starting to reach Logan County. Additional development signs all the way south through northern Grady County in the West Metro. Severe weather risk is increasing for points along and east of I-35.

    Looks like the tail end may or may not get to Oklahoma City, more likely Stillwater. Whatever, it's such a narrow, rather fast moving line, it probably won't be able to dump much rain.

    SPECIAL WEATHER STATEMENT:

    This significant weather advisory is for kay...logan...noble and payne counties. At 918 pm cst...a line of strong thunderstorms was located from 6 miles east of hardy...to ponca city...near perry...to 7 miles northwest of orlando...moving southeast at 40 mph. Hazards include...
    Hail up to the size of nickels...
    Wind gusts to 50 mph...

  11. Default Re: Oklahoma Weather Discussion - January/February 2012

    Development is now increasing pretty rapidly south to the Red River just to the east of I-44. Southern Grady, East Comanche, McClain, and Stephens counties could get in on the fun here quickly.

    This appears HRRR is going to be almost dead on with the line popping just SE of downtown OKC.

    NWS STORM PREDICTION CENTER NORMAN OK

    AREAS AFFECTED...ERN KS...WRN MO...CNTRL/ERN OK

    CONCERNING...TORNADO WATCH 41...

    VALID 290347Z - 290445Z

    THE SEVERE WEATHER THREAT FOR TORNADO WATCH 41 CONTINUES.

    PRIMARILY A DAMAGING WIND THREAT PERSISTS WITH QLCS EXTENDING FROM
    ERN KS INTO N-CNTRL OK...WITH A HISTORY OF MEASURED SEVERE WIND
    GUSTS ACROSS S-CNTRL KS/N-CNTRL OK. A MORE ISOLATED DAMAGING WIND
    RISK AND PERHAPS A BRIEF TORNADO MAY DEVELOP INTO PORTIONS OF WRN MO
    ALONG THE NRN PORTION OF THE LINE...AND SWWD OF THE LINE ACROSS
    CNTRL OK. AREAS DOWNSTREAM OF WW 41 ARE BEING MONITORED FOR POSSIBLE
    WW ISSUANCE OR LOCAL WFO EXTENSIONS.

    NRN PORTION OF QLCS HAS ESSENTIALLY OVERTAKEN AND PINCHED OFF THE
    RICHER WARM SECTOR...WITH SURFACE DEW POINTS AOA THE UPPER 50S
    REMAINING RELEGATED FROM SERN KS ON SWD. DESPITE THE PRESENCE OF
    60-70 KT SWLYS AROUND 1 KM AGL PER AREA VWP AND PROFILER DATA...A
    MEAGERLY BUOYANT DOWNSTREAM AIR MASS ACROSS MOST OF W-CNTRL/NWRN MO
    SHOULD MITIGATE POTENTIAL FOR DAMAGING WINDS/TORNADOES BEYOND A
    LOCALIZED/BRIEF THREAT.

    FARTHER SW ACROSS SERN KS INTO NERN OK...A BROADER WARM SECTOR AND
    STRONGER SURFACE PRESSURE RISE/FALL COUPLET WILL REMAIN CONDUCIVE TO
    SCATTERED SEVERE WIND GUSTS AND POTENTIALLY A TORNADO OR TWO.

    ADDITIONAL CU/SMALL CB DEVELOPMENT IS APPARENT DOWN TO THE RED
    RIVER. ALTHOUGH REMOVED FROM THE LARGER INFLUENCE OF THE CNTRL
    PLAINS SHORT WAVE TROUGH...70-80 KT EFFECTIVE SHEAR WOULD SUPPORT A
    RISK FOR DAMAGING WINDS/BRIEF TORNADOES SHOULD TSTM DEVELOPMENT
    BECOME SUSTAINED.
