KEY MESSAGES
* WITH A FEW EXCEPTIONS, DRY CONDITIONS ALONG WITH SEASONAL
TEMPERATURES WILL CONTINUE INTO NEXT WEEK FOR MOST OF THE REGION.
DISCUSSION
THROUGH MONDAY.
MUCH OF THE REGION WILL CONTINUE TO SEE DRY CONDITIONS ALONG WITH
SEASONABLE TEMPERATURES INTO THE WEEKEND AS DRY, SOUTHWESTERLY FLOW
ALOFT REMAINS IN PLACE. THERE CONTINUE TO BE A FEW EXCEPTIONS TO
THIS, THE FIRST OF WHICH IS ALONG THE SIERRA IN THE NORTHERN HALF OF
INYO COUNTY. MODEST MOISTURE IN PLACE ALONG THE CREST, ALONG WITH
UPSLOPE FLOW THIS AFTERNOON AND EVENING, WILL RESULT IN A FEW
ISOLATED THUNDERSTORMS DEVELOPING. THIS ACTIVITY SHOULD REMAIN
ANCHORED ALONG THE CREST, AND NO STORMS ARE EXPECTED DOWN IN THE
OWENS VALLEY. SIMILAR ACTIVITY IS EXPECTED TOMORROW AFTERNOON
BEFORE DRIER AIR MOVES IN FOR THE REMAINDER OF THE WEEK. LATER IN
THE WEEK, MONSOONAL MOISTURE OVER ARIZONA WILL SHIFT A BIT FURTHER
WEST. PWATS OVER FAR SOUTHERN AND EASTERN MOHAVE COUNTY INCREASE TO
AROUND .75" BY FRIDAY AFTERNOON, LEADING TO A 10 TO 20% CHANCE OF
AFTERNOON STORMS. HOWEVER, THIS SLIGHT INCREASE IN POPS WILL BE
SHORT-LIVED AS THE DRY SOUTHWESTERLY FLOW SCOURS OUT THE MOISTURE BY
THE WEEKEND.
FIRE WEATHER
SOUTHERLY WINDS ACROSS NORTHERN AND EASTERN PORTIONS
OF LINCOLN COUNTY WILL APPROACH RED FLAG CRITERIA TOMORROW
AFTERNOON. RH VALUES WILL FALL TO AROUND 10% DURING THE AFTERNOON,
BUT GIVEN THE MARGINAL WINDS EXPECTED AND LIMITED COVERAGE, I HAVE
ELECTED NOT TO ISSUE A RED FLAG WARNING AT THIS TIME. BORDERLINE
CONDITIONS WILL CONTINUE INTO THURSDAY, BUT ONCE AGAIN, NO PRODUCTS
ARE ANTICIPATED AT THIS TIME. MODEST RH RECOVERY CAN BE EXPECTED
OVERNIGHT, WITH VALUES INCREASING TO 15 TO 20%. WHILE NO PRODUCTS
HAVE BEEN ISSUED, ELEVATED FIRE CONDITIONS WILL EXIST, AND EXTREME
CAUTION IS ADVISED.
