DISCUSSION
STRONG NORTHWEST WINDS WITH GUSTS TO AROUND 30 MPH WILL BE THE
PRIMARY CONCERN TODAY. HUMIDITY COULD DROP BELOW 40 PERCENT
DEPENDING ON THE AMOUNT OF DRY AIR THAT MIXES DOWN. WIND CHILL
VALUES WILL BE IN THE TEENS TO PERHAPS LOW 20S MUCH OF THE DAY.
AN ISOLATED SNOW SHOWER OR SOME FLURRIES ARE POSSIBLE, ESPECIALLY
THIS MORNING, WITH LITTLE TO NO ACCUMULATION EXPECTED. WINDS WILL
DIMINISH TONIGHT INTO SUNDAY AS HIGH PRESSURE BUILDS IN. IT WILL
BE VERY COLD BUT DRY.
