AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
300 PM CDT THU SEP 15 2005

.SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT
COLD FRONT HAS MADE IT INTO THE AREA BUT IS DISINTEGRATING INTO
OUTFLOW BOUNDARIES FROM CONVECTION WHICH SHOULD SLOWLY MOVE TO THE
SOUTH TONIGHT INTO FRIDAY. RAIN HAS ABOUT ENDED IN THE NORTHWEST
WITH SCATTERED CONVECTION BREAKING OUT ALONG AND AHEAD OF THE
OUTFLOW BOUNDARY AND AN AREA OF SHOWERS AND THUNDERSTORMS MOVING
INTO CENTRAL AND SOUTHWESTERN SECTIONS FROM OKLAHOMA. EXPECT MOST
OF THE ACTION THE REST OF TODAY INTO THIS EVENING TO BE IN THE
SOUTHERN HALF OF THE CWA WITH THE PRECIPITATION SLOWLY SHIFTING TO
THE SOUTHEAST...POSSIBLY TAKING UNTIL EARLY FRIDAY TO COMPLETELY
LEAVE THE AREA. WENT WITH CHANCE POPS IN CENTRAL AND SOUTHERN AREAS
FOR EARLY TONIGHT AND SLIGHT CHANCE POPS IN THE NORTHWEST WITH POPS
DECREASING LATER TONIGHT. CONTINUED SMALL POPS IN THE SOUTHEAST
EARLY FRIDAY THEN WENT DRY THROUGH THE WEEKEND AS AN UPPER RIDGE
REBUILDS (RELOADS??) ACROSS THE AREA. A SHORT WAVE ROTATES AROUND
THE RIDGE BY LATE SUNDAY BUT LOOKS LIKE ITS EFFECTS WILL STAY NORTH
OF THE CWA RIGHT NOW. WENT CLOSE TO MAV MOS ON TEMPS BUT WENT NEAR
OR A LITTEL BELOW ON MINS FRIDAY NIGHT WHEN STRONG RADIATIONAL
COOLING SHOULD BE IN PLACE.

.LONG TERM...MONDAY THROUGH THURSDAY
HIGH PRESSURE WILL HOLD STRONG OVER THE MID SOUTH EARLY NEXT
WEEK...WITH DRY CONDITIONS CONTINUING. NEW MODEL RUNS ARE
INCONSISTENT WITH PLACEMENT OF COLD FRONT TO THE NORTH OF ARKANSAS.
