.AVIATION...
12Z TAFS... VFR AND MVFR CEILINGS THROUGH TONIGHT AT MOST SITES.
SPORADIC CEILINGS OF IFR OR LOWER WILL BE POSSIBLE THIS MORNING AT
SOME SITES. RAIN AND ISOLATED THUNDERSTORMS WILL BE POSSIBLE AT
MANY SITES THROUGH TONIGHT.

&&

.PREV DISCUSSION... /ISSUED 356 AM CDT TUE MAR 20 2012/

DISCUSSION...
RAIN AND ISOLATED THUNDERSTORMS WILL CONTINUE TO AFFECT
MAINLY SE HALF OF THE FA THIS MORNING. ADDITIONAL SHOWERS/ISOLATED
STORMS ARE EXPECTED TO DEVELOP THIS AFTERNOON... ESPECIALLY IN
WESTERN/NORTHERN PORTIONS OF FA AS THE UPPER LOW CONTINUES TO SLOWLY
MOVE TOWARDS THE FA. THE CHANCE FOR THUNDERSTORMS WILL BE HIGHEST
NEAR THE COLD CORE OF THE UPPER LOW. THE ADDITIONAL RAIN OVER
ALREADY WET SOILS WILL ALSO CONTINUE THE POSSIBILITY OF SOME
FLOODING SO WILL CONTINUE WITH THE FLASH FLOOD WATCH.

MODELS SHOW THE UPPER LOW MEANDERING AROUND THE SOUTHERN/CENTRAL
PLAINS OVER THE NEXT FEW DAYS. THIS WILL LEAD TO A PERSISTENCE OF A
CHANCE OF SHOWERS AND SOME THUNDERSTORMS THROUGH THURSDAY...
ESPECIALLY ACROSS PARTS OF NORTHERN/CENTRAL OK WHICH IS EXPECTED TO
BE CLOSEST TO THE UPPER LOW CENTER. RAIN CHANCES WILL BEGIN TO END
THURSDAY AS THE UPPER LOW FINALLY BEGINS TO LIFT NORTHEAST OUT OF
THE AREA. MID AND UPPER LEVEL RIDGE WILL THEN INFLUENCE THE REGION
OVER THE WEEKEND WITH SOUTHWEST FLOW DEVELOPING EARLY NEXT WEEK AS
THE RIDGE SHIFTS EAST. THIS WILL LEAD TO WARM TEMPERATURES OVER THE
WEEKEND INTO EARLY NEXT WEEK. DISTURBANCES IN THE SOUTHWEST FLOW
COULD ALSO CAUSE SOME SHOWER AND THUNDERSTORMS BUT WITH THE
UNCERTAINTIES WILL KEEP THE FORECAST DRY EARLY NEXT WEEK.
