.DISCUSSION...

A WEAK COOL FRONT WILL MOVE THROUGH THE AREA AFTER 0400 SHIFTING WINDS INTO
THE NORTHEAST...THEN BACK INTO THE NORTH. THE COOLER AIR WILL LIMIT SMOKE
DISPERSION TO POOR TO FAIR UNTIL ABOUT 1000 TO 1100 AS WINDS TEND TO TRAP THE
SMOKE AGAINST THE MOUNTAINS. WINDS WILL SHIFT INTO THE NORTHEAST AS ANOTHER SURGE
OF COOLER AIR PUSHES INTO THE AREA AROUND 0800 TO 0900...WITH SOME GUSTS TO 18
TO 22 MPH FOR AN HOUR OR SO. INCREASING MOISTURE AND DAYTIME HEATING WILL
ALLOW ISOLATED THUNDERSTORMS TO DEVELOP OVER THE MOUNTAINS AND MOVE OFF TO
THE EAST DURING THE AFTERNOON.
