SHORT TERM...TODAY THROUGH THURSDAY NIGHT

NO SIGNIFICANT CHANGES HAVE BEEN MADE TO THE SHORT TERM FORECAST
THIS AFTERNOON. REGIONAL RADAR IMAGERY SHOWS A VERY NARROW E-W
ORIENTED BAND OF SHOWERS EDGING THEIR WAY EASTWARD FROM OKLAHOMA
INTO NORTHWEST ARKANSAS. THIS AREA OF SHOWERS IS TRACKING NICELY
WITH A WEAK DISTURBANCE IN THE UPPER LEVELS...WHICH IS FORECAST TO
START DIVING SOUTH THROUGH WESTERN ARKANSAS THIS AFTERNOON AND
EVENING. LEFT A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS IN THE
WEST AND SOUTHWEST THIS AFTERNOON THROUGH ROUGHLY MIDNIGHT TO
ACCOUNT FOR THIS POSSIBILITY.

OTHERWISE THE SHORT TERM WILL BE DRY AND COOLER THAN SEASONAL
NORMS. A HIGH AMPLITUDE UPPER PATTERN IS CURRENTLY EVOLVING AND
WILL FEATURE A TROUGH OVER THE GREAT LAKES AND EASTERN CONUS...AND
A LARGE RIDGE OVER THE FOUR CORNERS REGION. THIS WILL MAINTAIN
NORTHERLY UPPER AND LOW LEVEL FLOW ACROSS ARKANSAS...KEEPING
TEMPERATURES DOWN BELOW NORMAL BUT JUST AS IMPORTANTLY KEEPING
THE HUMIDITY LEVELS DOWN AS WELL. THIS PATTERN WILL LAST THROUGH
THE END OF THE SHORT TERM PERIOD.

LONG TERM...FRIDAY THROUGH MONDAY NIGHT

A FRONTAL BOUNDARY WILL BE APPROACHING THE FA BY THE START OF THE
LONG TERM. MINIMAL POPS NOTED OVER THE FAR NORTHERN COUNTIES WITH
FRONT EXPECTED TO WASH OUT OVER THE STATE THIS WEEKEND. MOST OF THE
MOISTURE WILL BE ABSORBED INTO THE REMNANTS OF DANNY AS IT MAKES
LANDFALL IN FLORIDA AND MOVES UP THE ATLANTIC COAST. TEMPS WILL
REBOUND BACK INTO THE UPPER 80S TO LOWER 90S WITH LOWS IN THE 60S
FOR THE WEEKEND.
