MEANWHILE...SCATTERED SHOWERS/THUNDERSTORMS WORKING NORTHWARD
FROM LOUISIANA. WILL KEEP CHANCE FOR PRECIPITATION THIS
EVENING IN NORTHERN COUNTIES AND ALSO IN SOUTH. ONLY

PRECIPITATION PRETTY MUCH GONE BY MIDNIGHT.

WEAK AREA OF LOW PRESSURE/SHEAR AXIS WILL CONTINUE FROM

.LONG TERM...SUNDAY NIGHT THROUGH THURSDAY
SEE NO REASON TO MAKE ANY MAJOR CHANGES TO THE EXTENDED FORECAST

THE PERIOD. SOUTHWESTERLY/SOUTHERLY FLOW WILL BE NOTED AT THE

OF A LARGE SCALE FOCUSING MECHANISM...ANY CONVECTION WILL BE
ISOLATED AND DIURNAL IN NATURE.

BY WEDNESDAY...UPPER RIDGE WILL SINK SOUTHWARD AND MAY EVEN SHOW A
LITTLE RETROGRESSION. NORTHWESTERLY FLOW WILL SET UP ACROSS
NORTHERN ARKANSAS. THIS WILL ALLOW SEVERAL IMPULSES TO MOVE DOWN IN
THE MEAN FLOW...KEEPING A CONTINUED CHANCE OF AFTERNOON AND EVENING
SHOWERS AND THUNDERSTORMS IN THE FORECAST.

BY THURSDAY...NORTHWESTERLY FLOW AT THE UPPER LEVELS MAY ALLOW A
SURFACE FRONT TO PUSH INTO THE AREA. HOWEVER...SOLUTIONS ARE ALWAYS
A BIT IFFY THIS FAR OUT. WITH PERSISTENT SUMMERTIME PATTERN FOR MUCH
OF THE PERIOD...WILL CONTINUE CURRENT POP AND SENSIBLE WEATHER
TRENDS OF DIURNAL ACTIVITY. MADE VERY LITTLE CHANGES TO
TEMPERATURES. (57)
