FRONT WILL DIMINISH AS IT PUSHES THROUGH THE REST OF THE STATE LATE
TONIGHT AND EARLY FRIDAY.

WINDS THROUGH THE EVENING WILL BE OUT OF THE SOUTHWEST, AND GENERALLY
LESS THAN 8 MPH. THE CHANCE FOR A SHOWER IS LESS THAN 30 PERCENT, AND
THE CHANCE FOR A THUNDERSTORM IS LESS THAN 20 PERCENT. FRIDAY LOOKS DRY
WITH NORTHWEST WINDS BEHIND THE FRONT.
