DISCUSSION
TEMPERATURES WILL HOVER IN THE 40-45F RANGE THROUGH SUNRISE, WITH SIMILAR
WIND CHILL VALUES. BRIEF AND MOSTLY WEAK SHOWERS WILL BE POSSIBLE THROUGH
6 AM (~30% CHANCE), WITH INCREASING POTENTIAL FOR SHOWERS OR AN ISOLATED
THUNDERSTORM AFTER SUNRISE (50-65% CHANCE). EXPECT WINDS TO REMAIN VERY
LIGHT THROUGH MID TO LATE MORNING, WITH SPEEDS GENERALLY 6 MPH OR LESS.
HOWEVER, BRIEF GUSTIER WINDS WILL BE POSSIBLE IN THE VICINITY OF ANY
SHOWERS OR THUNDERSTORMS, WITH MAXIMUM GUSTS OF AROUND 25-30 MPH, ALTHOUGH
CONFIDENCE IN THIS IS LOW.
EXPECT TEMPERATURES TO CLIMB INTO THE MID 60'S THIS AFTERNOON, WITH ISOLATED
SHOWERS AND WEAK THUNDERSTORMS IN THE GENERAL AREA CONTINUING MUCH OF THE DAY.
FOR THE AFTERNOON, WINDS WILL FAVOR A WESTERLY DIRECTION, WITH PEAK GUSTS IN
