DISCUSSION
SMOKE FROM THE GARNET FIRE CONTINUES TO FILTER OVER THE SIERRA PER
LATEST SATELLITE OBS, WHICH IS PRODUCING SOME HAZY SKIES ACROSS MONO
COUNTY. SMOKE WILL LIKELY LINGER INTO THE EVENING BUT SHOULD
DISPERSE ON TUESDAY. TRANSIENT HIGH PRESSURE ALOFT WILL SUPPORT WARM
AND DRY WEATHER ACROSS THE REGION THROUGH MIDWEEK. DAYTIME HIGHS
WILL BE IN THE 70S AND 80S EACH DAY THROUGH WEDNESDAY WITH LOWEST
VALLEYS FLIRTING WITH 90F.
SHOWER AND THUNDERSTORM ACTIVITY LIKELY INCREASES THURSDAY AND OVER
THE WEEK AS LOW PRESSURE IN THE EASTERN PACIFIC DRAWS RICH MOISTURE
INTO THE REGION. CHANCES BEGIN TO INCREASE THURSDAY IN RESPONSE TO
MOISTURE FILTERING INTO THE REGION FROM THE SOUTH. THUS, BEST ODDS
OF AFTERNOON SHOWERS AND STORMS THURSDAY WILL EXIST SOUTH OF US-50
WITH GREATER UNCERTAINTY FARTHER NORTH. THERE IS ALSO THE POTENTIAL
FOR NOCTURNAL THUNDERSTORMS THURSDAY NIGHT INTO FRIDAY MORNING. ODDS
AND COVERAGE OF THUNDERSTORMS REMAIN FAVORED TO PEAK ON FRIDAY AND
SATURDAY BEFORE WANING SUNDAY INTO EARLY NEXT WEEK. THERE IS STILL
MUCH UNCERTAINTY IN THE EXACT DETAILS (E.G, TIMING, MAIN HAZARDS,
ETC) SO BE SURE TO STAY UP TO DATE WITH THE LATEST FORECAST!
