.DISCUSSION...

STRONG SOUTHERLY WINDS ARE EXPECTED AGAIN THIS AFTERNOON AS TIGHT
PRESSURE GRADIENT FORMS AS A RESULT OF A DEVELOPING SURFACE LOW
PRESSURE TO THE WEST OF ARKANSAS. EXPECT WINDS OF 15 TO 20
MPH..WITH GUSTS OF 25 TO 30 MPH. MIN RH VALUES SHOULD REMAIN
AROUND 40 TO 50 PERCENT SINCE GULF MOISTURE HAS BEEN STREAMING
NORTHWARD THE PAST COUPLE DAYS. THERE IS A SLIGHT CHANCE FOR
SHOWERS AND THUNDERSTORMS TODAY...MAINLY ACROSS WESTERN PORTIONS
OF THE STATE. SOUTHWEST FLOW ALOFT COMBINED WITH AN APPROACHING
FRONT FROM THE NORTH WILL BRING BETTER CHANCES FOR SHOWERS AND
THUNDERSTORMS ACROSS MOST OF THE STATE STARTING SUNDAY INTO
MONDAY. THIS FRONT WILL THEN STALL ACROSS THE REGION TUESDAY...AND
WITH SEVERAL IMPULSES OF UPPER LEVEL ENERGY STREAMING ACROSS THE
SOUTHERN AND CENTRAL PLAINS DURING THE WEEK...EXPECT CONTINUING
UNSETTLED WEATHER THROUGH MUCH OF NEXT WEEK.
