A STRONG COLD FRONT WILL SWEEP THROUGH THE REGION LATE TONIGHT AND
THURSDAY.  THIS FRONT WILL GENERATE NUMEROUS SHOWERS AND SOME

WIND OF THIS MAGNITUDE IS SUFFICIENT TO DOWN SOME BRANCHES...BLOW

SUDDEN CROSS GUSTS.

IN ADDITION...THIS FRONT WILL DROP TEMPERATURES DECISIVELY.

UPPER 30S FOR FRIDAY MORNING.  SOME PATCHY FROST IS POSSIBLE OVER
AREAS NORTH OF BUTLER...AND OVER THE RIDGE COUNTIES TO THE SOUTH AND
EAST OF PITTSBURGH.  ALTHOUGH GROUND TEMPERATURES ARE
WARM...RESIDENTS OF OUTLYING AREAS MAY WANT TO COVER THEIR SENSITIVE
PLANTS AND MAKE PREPARATIONS FOR PETS.
