DISCUSSION
KEY MESSAGE 1: INCREASED FIRE WEATHER CONCERNS PERSIST AND
COOLER WEATHER WILL OCCUR THROUGH MIDWEEK BEFORE THE NEXT WARM
UP.
WINDS SHOULD DECREASE OVERNIGHT AND OVERNIGHT LOWS SHOULD FALL
INTO THE 40S WHICH IS MUCH COOLER THAN WE'VE SEEN OVER THE PAST
SEVERAL DAYS. DRY HIGH PRESSURE OVERSPREADS THE AREA AND SHOULD
REMAIN IN PLACE MUCH OF THE UPCOMING WEEK. AFTER A FEW DAYS OF
NEAR NORMAL TEMPERATURES, VALUES WILL AGAIN PUSH ABOVE NORMAL
INTO THE MID 80S WEDNESDAY AND UPPER 80S POSSIBLE THURSDAY AND
FRIDAY. WE MAINTAIN AN ELEVATED FIRE WEATHER RISK THIS WEEK
DESPITE WEAK WINDS OVERALL. MIN RH VALUES WILL BE NEAR CRITICAL
VALUES EACH DAY, GENERALLY IN THE LOW TO MID 20S. NOT TO GET TOO
EXCITED JUST YET, BUT THERE REMAINS A SIGNAL FOR A WETTER
PATTERN BEGINNING AT THE VERY END OF THIS PERIOD AND TOWARDS THE
BEGINNING OF MAY.
AVIATION /00Z MONDAY THROUGH FRIDAY/
VFR CONDITIONS EXPECTED THROUGH THE TAF PERIOD.
THE LAST OF THE MID TO HIGH LEVEL CLOUD SHIELD IS MOVING THROUGH
THE FORECAST AREA THIS EVENING. ONCE THESE CLOUDS MOVE OUT,
EXPECT MAINLY CLEAR SKIES THROUGH MUCH OF THE TAF PERIOD. WINDS
ARE EXPECTED TO BE LIGHT AND VARIABLE TO CALM THROUGH THE
OVERNIGHT HOURS. WINDS PICK UP AGAIN TO 5-10 KTS FROM THE W TO
NW AFTER ABOUT 15Z OR 16Z, WITH SOME GUSTS AROUND 15 KTS AT
TIMES.
