Area forecast discussion, Mar 31, 2:38 AM CST, 1 hour 50 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 338 AM CDT SAT MAR 31 2012 .DISCUSSION... ONE SMALL AREA OF STORMS HAS DEVELOPED THIS MORNING ACROSS PORTIONS OF SOUTH CENTRAL INTO SOUTHEAST OKLAHOMA AS MID LEVEL WAVE EXITS. WILL KEEP A PRE-FIRST PERIOD WORDING TO ACCOUNT FOR THIS ACTIVITY... BUT EXPECT IT TO MOVE OUT OF THE AREA LATER THIS MORNING. REMAINDER OF THE WEEKEND SHOULD REMAIN UNDER THE INFLUENCE OF MID LEVEL RIDGING. THIS WILL KEEP THINGS DRY AND VERY WARM FOR LATE MARCH/EARLY APRIL. AFTER SOME EARLY MORNING FOG TODAY EXPECT TO SEE MOSTLY SUNNY SKIES AND RELATIVELY LIGHT SOUTH WINDS TODAY WITH WIND PICKING UP SOME ON SUNDAY. THIS WILL BE IN RESPONSE TO APPROACHING STORM SYSTEM THAT WILL IMPACT THE SOUTHERN PLAINS EARLY NEXT WEEK. NEAR RECORD TEMPS ARE FORECAST FOR SUNDAY WITH GUSTY SOUTH WINDS... COULD BE SOME ELEVATED FIRE WEATHER CONCERNS ACROSS FAR WESTERN OKLAHOMA INTO WESTERN NORTH TEXAS. HOWEVER WITH RECENT RAINS HAVE SEEN SOME GREEN-UP WITH VEGETATION EVEN OUT WEST AND DO NOT ANTICIPATE NEED FOR FIRE WEATHER WATCH/RED FLAG WARNINGS AT THIS TIME. THERE IS STILL QUITE A BIT OF UNCERTAINTY ASSOCIATED WITH THE STORM SYSTEM NEXT WEEK. MODELS DO AGREE THAT THE WAVE WILL CLOSE OFF TO OUR WEST AND HAVE TRENDED SLOWER WITH ITS EASTWARD PROGRESSION THROUGH THE AREA. THE GFS TRANSLATES THE LOW FARTHER NORTH INTO KANSAS WITH OKLAHOMA MORE UNDER THE INFLUENCE OF DRY SLOT... WHILE ECMWF BRINGS THE UPPER LOW ALMOST DIRECTLY OVERHEAD THROUGH THURSDAY KEEPING RAIN CHANCES LINGERING ACROSS THE AREA THROUGH MUCH OF NEXT WEEK. FOR NOW WILL KEEP SOME LOW POPS THROUGH TUESDAY BEFORE DRYING THINGS OUT... BUT OBVIOUSLY WILL HAVE TO CONT TO MONITOR TRENDS CLOSELY. AS FOR MONDAY... BOTH GFS AND NAM SUGGEST AN EPISODE OF STRONG TO SEVERE STORMS DEVELOPING ACROSS THE AREA ALONG AND TO THE EAST OF THE DRYLINE LATE MONDAY AFTN AND LINGERING THEM INTO MONDAY NIGHT. AT THIS POINT THIS WOULD APPEAR TO AFFECT ABOUT THE EASTERN TWO- THIRDS OF OKLAHOMA WITH MUCH OF WESTERN OKLAHOMA AND WESTERN NORTH TEXAS REMAINING DRY. AGAIN WILL NEED TO WATCH TRENDS AS MODELS ARE TRENDING SLOWER AND THIS IN TURN HAS ALLOWED PRECIP IN THE MODELS TO DEVELOP FARTHER WEST THAN EARLIER RUNS. && .PRELIMINARY POINT TEMPS/POPS...
