DISCUSSION
AREAS OF PATCHY FOG ARE EXPECTED AGAIN THIS MORNING ACROSS THE
MARTIS VALLEY/TRUCKEE AREA THROUGH ABOUT SUNRISE BEFORE QUICKLY
DISSIPATING AS CONDITIONS CONTINUE TO TREND DRIER TODAY. ASIDE
FROM SHALLOW AFTERNOON CUMULUS DEVELOPMENT, MOSTLY SUNNY
CONDITIONS WILL PREVAIL TODAY WITH LIGHTER WINDS AREAWIDE.
AS AN AREA OF LOW PRESSURE BUILDS OFF THE PACIFIC NORTHWEST, A
BREEZY PATTERN WILL BEGIN TO DEVELOP FOR MUCH OF THE UPCOMING WEEK
WITH TYPICAL AFTERNOON BREEZES MONDAY PROGRESSING TO GUSTY
CONDITIONS BY TUESDAY. DRY CONDITIONS COMBINED WITH SW GUSTS UP
TO 30-40 MPH MAY YIELD CRITICAL FIRE WEATHER CONDITIONS FOR
PORTIONS OF NE CALIFORNIA AND NW NEVADA. IN ADDITION, AVIATION
IMPACTS FROM INCREASED TURBULENCE/WIND SHEAR AND OUTDOOR
RECREATIONAL IMPACTS FROM CHOPPY LAKE WATERS ARE POSSIBLE.
COOLER CONDITIONS WILL ALSO PREVAIL BY MID-WEEK WITH ABOUT 10
DEGREES OF COOLING FROM MONDAY TO WEDNESDAY WITH HIGHS ONLY
REACHING INTO THE UPPER 70S MID-WEEK. CONDITIONS WILL REMAIN
BREEZY FROM MID-WEEK THROUGH THE WEEKEND BUT FIRE WEATHER IMPACTS
MAY BEGIN TO BE MITIGATED AS MOISTURE BEGINS TO FILTER INTO THE
REGION. OVERALL SHOWER CHANCES WILL INCREASE ACROSS FAR NE
CALIFORNIA AND NW NEVADA BY THURSDAY WITH 15-30% CHANCES FOR
LIGHT SHOWERS INTO THE START OF THE WEEKEND. FUENTES
AVIATION
VFR CONDITIONS WILL PREVAIL FOR W.NEVADA AND E.SIERRA TERMINALS
OUTSIDE OF AREAS OF PATCHY FOG AT KTRK THOUGH 15Z THIS MORNING.
WINDS WILL BE LIGHTER THIS AFTERNOON WITH AFTERNOON GUSTS OF
AROUND 15 KNOTS. TYPICAL AFTERNOON GUSTS OF 20-25 KTS RETURN BY
MONDAY, BUT INCREASING CHANCES FOR GUSTY WINDS, MOUNTAIN WAVE
TURBULENCE, AND LLWS IS EXPECTED ON TUESDAY AS A LOW PRESSURE
APPROACHES THE REGION. FUENTES
FIRE WEATHER
ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS RETURN EARLY THIS
WEEK AS WINDS START TO SLOWLY INCREASE WITH THE APPROACH OF
ANOTHER UPPER LEVEL TROUGH.
ON MONDAY, POOR RH RECOVERY IS EXPECTED ACROSS PORTIONS OF THE
W.NEVADA BASIN AND RANGE WITH ELEVATED TO NEAR CRITICAL CONDITIONS
EXPECTED FOR PORTIONS OF NORTHERN WASHOE, THE SURPRISE VALLEY AND
EASTERN LASSEN COUNTY AS RH DROPS INTO THE TEENS WHILE AFTERNOON
WINDS GUST TO 20-30 MPH.
TUESDAY WILL SEE THE BEST POTENTIAL FOR WIDESPREAD CRITICAL FIRE
WEATHER CONCERNS AS CONDITIONS DETERIORATE IN MUCH OF THE SAME
REGION, BUT ALSO EXTENDING SOUTHWARD INTO THE SIERRA FRONT.
SOUTHWESTERLY WIND GUSTS IN THE AFTERNOON COULD SEE GUSTS OF 30-40
MPH WITH MIN RH GENERALLY IN THE 10-20% RANGE FOR MOST AREAS
ACROSS W.NEVADA AND NE CALIFORNIA.
BY WEDNESDAY, WINDS ONLY DIMINISH SLIGHTLY BUT MIN RH CONTINUES
TO INCREASE, REDUCING OUR RISK FOR CRITICAL CONDITIONS. BREEZY
CONDITIONS PERSIST THROUGH THE REST OF THE WEEK, BUT WE WILL HAVE
INCREASING RH WITH SHOWER CHANCES WHICH MAY HELP TO FURTHER LIMIT
FIRE RISK. HC/FUENTES
