AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 1156 PM CDT SAT APR 4 2009 .UPDATE... QUICK UPDATE TO INCREASE POPS IN SE OK NOW THAT THUNDERSTORMS HAVE DEVELOPED. TAYLOR && .PREV DISCUSSION... /ISSUED 934 PM CDT SAT APR 4 2009/ UPDATE... WE COMPARED SOME OF THE LATEST MODEL DATA WITH THE CURRENT POSITION OF THE COLD FRONT...AND SOME SLIGHT CHANGES WERE MADE TO THE WIND SPEED AND DIRECTION FORECASTS FOR TONIGHT. HOURLY TEMPERATURE GRIDS WERE UPDATED TO MORE ACCURATELY REFLECT FROPA DURING THE NEXT SEVERAL HOURS. ALSO...PRECIP CHANCES WERE EXTENDED UNTIL THE COLD FRONT EXITS THE CWA AT AROUND 09Z. MOISTURE IS ON THE MODEST SIDE...BUT THE POSSIBILITY EXISTS FOR SOME ISOLATED THUNDERSTORMS IN OUR SOUTHEAST COUNTIES AS THE FRONT MOVES THROUGH. SHORT TERM MODELS HAVE CAUGHT ON TO THIS AS WELL. TAYLOR PREV DISCUSSION... /ISSUED 620 PM CDT SAT APR 4 2009/ AVIATION... STRONG SURFACE LOW WILL CONTINUE TO MOVE EWD ACROSS KANSAS THIS EVENING. DRYLINE HAS PUSHED EAST OF TAF SITES ENDING ANY THREAT OF TSTMS AND COLD FRONT WHICH PUSHED INTO NW OK THIS AFTN WILL CONTINUE SEWD THROUGH THE AREA TONIGHT. EXPECT FRONT TO CLEAR SRN TAF SITES BY 06Z. MVFR CIGS EXPECTED TO MOVE INTO NRN AND EVEN CNTRL OK LATER TONIGHT AS CLOUDS WRAP AROUND BACK SIDE OF THE LOW. CIGS WILL LIKELY CONTINUE FOR MUCH OF THE DAY SUNDAY AT PNC AND PSBLY OKC. PREV DISCUSSION... /ISSUED 321 PM CDT SAT APR 4 2009 DISCUSSION... DEEP SURFACE AND UPPER LEVEL LOW OVER NORTHWEST KANSAS WILL MOVE EAST ACROSS KANSAS AND MISSOURI TONIGHT. VERY WARM TEMPERATURES OVER WESTERN OKLAHOMA HAS RESULTED IN DEEP MIXING TO NEAR 700 MB WHERE WINDS WERE ESTIMATED TO BE NEAR 60 KTS. THIS FACTOR... COMBINED WITH A TIGHTER SURFACE PRESSURE GRADIENT ACROSS NORTHERN OKLAHOMA... HAS RESULTED IN WIND GUSTS 50 TO 60 MPH OVER PARTS OF NORTHWEST OKLAHOMA. WE EXPECT TO SEE THE EXCESSIVE WIND SPEEDS SUBSIDE SOMEWHAT LATER THIS AFTERNOON. A COLD FRONT MOVING INTO THE FAR NORTHWEST BODY OF OKLAHOMA THIS AFTERNOON... WILL TRACK ACROSS THE REMAINDER OF THE AREA BY LATE TONIGHT. WINDS WILL SHIFT TO THE NORTHWEST BEHIND THE FRONT... AND WHILE SPEEDS WILL REMAIN BRISK... THE GUSTS WILL BE MUCH LESS... AVERAGING CLOSER TO 30-35 MPH. MEANWHILE... WILL LEAVE IN SOME LOW POPS ACROSS THE SOUTHEAST PART OF THE CWA FOR THIS EVENING. SOME DEWPOINT RECOVERY HAS OCCURRED IN THESE AREAS DURING THE AFTERNOON... AND MAY SEE SUFFICIENT INSTABILITY FOR A FEW STORMS TO DEVELOP ALONG/AHEAD OF THE DRYLINE/COLD FRONT. COOLER TEMPERATURES IN STORE FOR SUNDAY AS BRISK NORTH WINDS CONTINUE BEHIND THE FRONT. MODEL GUIDANCE IS GENERATING SOME LOW POPS ACROSS NORTHERN OKLAHOMA ON SUNDAY AS ANOTHER SPEED MAX ROTATES THROUGH THE BASE OF THE UPPER TROUGH. HOWEVER... WILL OPT TO KEEP THE FORECAST DRY AS VERTICAL MOISTURE AND STABILITY PROFILES ARE LESS THAN OPTIMAL. EVEN THOUGH THE NAM MOISTENS UP THE LAYER BETWEEN 800-900 MB IN THE MORNING... THIS MOISTURE REMAINS CAPPED BEFORE THINNING OUT DURING THE AFTERNOON. NEAR FREEZING TEMPERATURES ARE EXPECTED TO REACH CENTRAL OKLAHOMA SUNDAY NIGHT... WITH LOWER VALUES TO THE WEST AND NORTH. IT CURRENTLY APPEARS THAT THE WINDS SUNDAY NIGHT WILL HOLD TEMPERATURES A LITTLE HIGHER THAN MIGHT OTHERWISE OCCUR BY DISRUPTING THE FORMATION OF A STRONG SURFACE INVERSION. COLDER TEMPERATURES ARE EXPECTED FOR MONDAY NIGHT AS THE SURFACE RIDGE AXIS WILL BE OVER THE AREA BY THAT TIME. IN THE LONGER TERM... DRY AND COOLER WEATHER IS EXPECTED THROUGH THE FIRST PART OF NEXT WEEK... WITH THE NEXT CHANCE FOR PRECIPITATION OCCURRING LATE WEDNESDAY AND AGAIN NEXT WEEKEND. && .PRELIMINARY POINT TEMPS/POPS...
