WEAK SHORTWAVE, A REMNANT MID-LEVEL FEATURE OF FORMER TROPICAL
STORM SARA, WILL LIFT NE OUT OF THE GULF OF MEXICO BY LATE
TUESDAY. AT THE SURFACE, A DEVELOPING STORM SYSTEM OVER N TX WILL
LIFT NNE TO N MN. A COLD FRONT WILL APPROACH THE AREA FROM THE NW
TONIGHT, WITH WIDESPREAD SHOWERS SPREADING INTO THE AREA FROM THE
W LATE TONIGHT AND EARLY TUESDAY MORNING. FORCING FROM THE
PRIMARY SHORTWAVE WILL WEAKEN AS THE STORM SYSTEM MOVES INTO THE
AREA, WITH ADDITIONAL SUPPORT FOR SHOWER ACTIVITY ACROSS THE S
ASSOCIATED WITH THE SARA REMNANT. AS A RESULT, THE HEAVIEST RAIN
TOTALS ARE EXPECTED ACROSS THE SW PORTION OF THE AREA, WHERE 1.5
TO 2" OF RAIN ARE POSSIBLE. RAINFALL TOTALS OVER THE E PORTION OF
THE AREA WILL BE CLOSER TO .25-.5". LITTLE IN THE WAY OF
THUNDERSTORM ACTIVITY IS ANTICIPATED. HOWEVER, A FEW STORMS ARE
POSSIBLE IN THE NW ON TUESDAY BEFORE DYNAMIC ENERGY WANES.

MOUNTAINS TO THE MID 70S ACROSS THE S HALF OF THE AREA. LOW
TEMPERATURES TONIGHT WILL RANGE FROM THE UPPER 40S IN THE NE
MOUNTAINS TO THE UPPER 50S IN THE SW. DUE TO CLOUD COVER AND

WEDNESDAY NIGHT AND INTO FRIDAY. THE HIGHS GUSTS WILL LIKELY OCCUR
OVER THE HIGHER ELEVATIONS OF NORTHERN GA WHERE GUSTS UP TO 30MPH
WILL BE POSSIBLE. A WIND ADVISORY MAY BE NEEDED AS WE MOVE INTO THE

ACCUMULATION IS EXPECTED.
A THE UPPER LEVELS, THE FLOW FLATTENS OUT AND WE GO ZONAL FOR THE
REMAINDER OF THE FORECAST AS HIGH PRESSURE BUILDS BACK IN. WHICH
MEANS THAT WE'RE NOT EXPECTING ANY ADDITIONAL PRECIP AS WE GO INTO
