MPH...AND GUSTS OF 25 TO 30 MPH WILL BE POSSIBLE. SPEEDS WILL BEGIN
TO DIMINISH BY LATE AFTERNOON/EARLY EVENING. TEMPERATURES ARE
A BIT TRICKY WITH A DAYTIME PASSAGE OF THIS COLD FRONT...BUT HIGHS

BEHIND THE FRONT ARE EXPECTED TO FALL INTO THE LOWER/MID
30S...RESULTING IN MINIMUM RELATIVE HUMIDITY VALUES APPROACHING 30
