THE MAIN FIRE WEATHER RELATED ISSUE TODAY WILL BE THE PASSAGE OF COLD
FRONT DURING THE MIDDAY HOURS. RIGHT NOW...LOOK FOR SOUTH/SOUTHWEST

WHICH WINDS WILL SHIFT TO THE NORTH/NORTHWEST AROUND 1 PM AND INCREASE
IN SPEEDS OF 20 TO 30 MPH WITH HIGHER GUSTS. WINDS WILL REMAIN STRONG
THROUGH SUNSET...THEN DROP OFF.

RELATIVE HUMIDITIES ARE CURRENTLY FORECAST TO BOTTOM OUT IN THE 30
TO 35 PERCENT RANGE. SOME CONCERN THE AIR WITH THE FRONT MAY BE A
BIT DRIER...AND THOSE RH VALUES COULD DROP INTO THE 25 TO 30 PERCENT
RANGE. DEPENDS UPON HOW MUCH WARMING PREVAILS PRIOR TO THE FRONT...
WITH HIGH A 62 EXPECTED AROUND 2 PM...THEN TEMPERATURES LEVELING
OR SLOWLY DROPPING OFF THERE AFTER.

THERE IS NO CHANCE FOR A WETTING RAIN TODAY OR TONIGHT.
