AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 118 AM CDT MON MAY 23 2005 .DISCUSSION... STORM COMPLEX NORTH OF FRONT IN KS SHOULD REINFORCE THE SURFACE FRONTAL POSITION ACROSS THE NORTHERN THIRD OF OK TODAY. THE CAP WILL REMAIN STRONG TODAY WEAKLY REINFORCE BY THE PASSAGE OF THE UPPER WAVE THROUGH THE OH VALLEY. THIS SHOULD INHIBIT STORM DEVELOPMENT MOST OF THE DAY ON THE OK PORTION OF THE FRONT. WEAK LOW PRESSURE IN THE NORTHERN TX PANHANDLE EXPECTED THIS AFTERNOON SHOULD MODESTLY ENHANCE CONVERGENCE ALONG THE NEARLY STATIONARY SURFACE FRONT, SO SHOWERS/STORMS MAY FORM DURING MAX HEATING IN NORTH CENTRAL OR NORTHWEST OK. HOWEVER, WITH A STRONGER CAP TO THE SOUTHWEST, NOT MUCH IS EXPECTED OUT OF THIS AREA, ESPECIALLY AFTER THE SUN GOES DOWN. SOUTHWEST BOUNDARY LAYER FLOW THIS AFTERNOON AROUND THE SURFACE LOW SHOULD HELP SOUTHWEST OK AND ADJACENT PARTS OF TX WARM CLOSE TO 100 AGAIN THIS AFTERNOON, WHILE NORTH CENTRAL OK SHOULD REMAIN IN THE 80S WITH 70+ DEGREE DEWPOINT AIR. THE ETA AND GFS DIFFER ON WHETHER THERE WILL BE UPSLOPE STORMS TONIGHT FROM CO INTO NM. TUESDAY NIGHT SEEMS THE MORE LIKELY NIGHT FOR STORMS MOVING OFF THE CO/NM HIGH PLAINS INTO NORTHWEST OK, ALTHOUGH VERY LOW POPS EXIST FOR TONIGHT. THIS SCENARIO WOULD ALLOW THE FRONT TO MOVE NORTH TO THE OK-KS BORDER REGION TUESDAY WITH LITTLE CHANCE FOR ANY BOUNDARY INTERACTION TUESDAY AFTERNOON IN OK. HOWEVER, WITH THE APPROACH OF A FRONT DRIVEN IN STRONGER NORTHWEST FLOW ALOFT LATE TUESDAY NIGHT, SHOWERS AND STORMS ARE A BETTER BET THAN ON MONDAY. SOME OF THESE MAY MAKE IT INTO NW OK EARLY WEDNESDAY MORNING PRECEDING THE FRONT. WEDNESDAY WILL BE THE BEST DAYTIME PERIOD FOR STORMS IN OK THIS WEEK WITH COOLER TEMPERATURES ALOFT AS AN UPPER WAVE PASSES TO THE NORTH AND A RESPECTABLE LATE-MAY SURFACE FRONT. IF THIS PANS OUT, THE FOLLOWING AIRMASS SHOULD KEEP DAYTIME TEMPERATURES IN THE 70S TO MIDDLE 80S THROUGH THE END OF THE WEEK. && .PRELIMINARY POINT TEMPS/POPS...

DISCUSSION...
A COLD FRONT LOCATED ACROSS NORTHWEST OKLAHOMA INTO SOUTHWEST
MISSOURI AT NOON WILL MOVE SLOWLY SOUTH TODAY INTO NORTHERN
OKLAHOMA. INITIALLY... AN ELEVATED WARM LAYER OF AIR IS EXPECTED TO
INHIBIT THUNDERSTORM DEVELOPMENT. HOWEVER CONVERGENCE ALONG THE
FRONT... ALONG WITH HOT AFTERNOON TEMPERATURES ARE EXPECTED TO BE
ENOUGH TO OVERCOME THIS WARM LAYER OF AIR FOR WIDELY SCATTERED
THUNDERSTORMS TO DEVELOP ACROSS NORTH CENTRAL OKLAHOMA LATE THIS
AFTERNOON. INSTABILITY AND WIND SHEAR WILL BE SUFFICIENT THAT ANY
STORM THAT DOES DEVELOP WILL HAVE THE POTENTIAL TO BECOME SEVERE
PRODUCING LARGE HAIL AND DAMAGING STRAIGHT-LINE WINDS. SOME OF THESE
THUNDERSTORMS WILL ALSO BE CAPABLE OF PRODUCING LOCALLY HEAVY
RAINFALL. THIS ACTIVITY WILL PUSH SOUTH INTO CENTRAL SECTIONS OF THE
STATE THIS EVENING AND OVERNIGHT.

EARLIER ACTIVITY WILL ACT AS FOCUSING MECHANISMS FOR THUNDERSTORM
DEVELOPMENT MONDAY AFTERNOON AND EVENING. MID LEVEL TEMPERATURES
ARE EXPECTED TO COOL ON MONDAY WITH SUFFICIENT INSTABILITY FOR ANY
