.SHORT TERM...AS THE SURFACE WINDS DIMINISH ATTENTION NOW SHIFTS
TOWARDS THE POTENTIAL FOR RADIATIONAL COOLING TONIGHT. IR SATL
IMAGERY SHOWS ONLY SOME PATCHY CLD COVER MOVING OVER THE REGION
FROM THE WEST. DEWPOINTS AROUND THE AREA RANGE IN THE LOWER TO
MIDDLE 30S WITH TEMPS RANGING IN THE LOWER TO MIDDLE 50S WITH THE
SURFACE WINDS RANGING FROM 10 TO 15 KNOTS. ALTHOUGH THE SURFACE
WINDS WILL DIMINISH SOME THROUGHOUT THE NIGHT BELIEVE THAT THE
SURFACE WINDS WILL REMAIN STRONG ENOUGH TO LIMIT THE RADIATIONAL
EFFECTS. HOWEVER WILL LOWER TEMPS SOME AROUND THE BRO CWA AND WILL
KEEP THE COLDEST TEMPS ACROSS THE NORTHERNMOST COUNTIES WITH MID
30S EXPECTED AT BKS AND HBV. SOME ISOLATED MORNING LOWS MAY REACH
NEAR THE FREEZING MARK BRIEFLY TOMORROW MORNING ESPECIALLY IN LOW
LYING RURAL AREAS. HOWEVER AT THIS TIME WILL NOT POST ANY FREEZE
WARNING. NO MAJOR CHANGES NEEDED TO THE REST OF THE CURRENT
FORECAST WORDING.

SKIES WILL REMAIN CLEAR INTO LATER TOMORROW AFTERNOON. CLOUDS WILL

DAYTIME HEATING...SO SFC WINDS WILL BE LIGHTER THAN WINDS JUST OFF

NOTES 50KTS AT 2KFT AND 65KTS AND 4KFT. WINDS ARE FORECAST TO
DECREASE THROUGH THE NIGHT...BUT SHEAR WILL REMAIN ABOVE 20KTS
