INTO CANADA SO THERE'S NOT A WHOLE LOT OF HOPE TO SEE MUCH SUN.
WEST WINDS WILL INCREASE TO 15 TO 20 MPH LATE THIS MORNING AND THEN
SHIFT TO THE WEST-NORTHWEST THIS AFTERNOON AFTER A COLD FRONT MOVES
THROUGH THE AREA. THE WIND SHIFT FROM WEST TO NORTHWEST WILL BE
VERY GRADUAL...ALTHOUGH GUSTS TO 30 MPH WILL BE POSSIBLE MUCH OF THE DAY.
MINIMUM RH VALUES HAVE BEEN ADJUSTED LOWER TO REFLECT INCREASED CLOUD
COVER AND LOWER TEMPERATURES...WITH DETAILS IN TABULAR FORM BELOW.
