* DRY AND MILD WEATHER IS FAVORED THROUGH THE WEEKEND, BUT A

DISCUSSION
THE HEAT IS ON IT'S WAY, AS A STRENGTHENING RIDGE OF HIGH PRESSURE
DRAWS NEARER. THE CENTER OF THE RIDGE CIRCULATION WILL MIGRATE
OVERHEAD OF THE SOUTHWESTERN REGION STARTING TUESDAY, WHICH WILL
SIGNAL THE BEGINNING OF 80S IN WESTERN NEVADA VALLEYS AND 70S FOR
SIERRA COMMUNITIES. BY THE END OF THE WEEK, UPPER 80S ARE EXPECTED
FOR WESTERN NEVADA, WITH LOWER VALLEYS ACROSS THE BASIN AND RANGE
FLIRTING WITH LOW 90S. UPPER 70S TO LOW 80S WILL BE FOUND IN
SIERRA VALLEYS ALONG US-395 IN ALPINE AND MONO COUNTIES FOR
THURSDAY AND FRIDAY. WE ARE ANTICIPATING RECORD HIGH TEMPERATURES
BEING CHALLENGED OR SET THIS WEEK, BEFORE THE RIDGE NUDGES
EASTWARD OVER THE FOLLOWING WEEKEND. OUR CHANCES FOR RECORD
BREAKING HIGH TEMPERATURES IS NEARING 100% FROM TUESDAY THROUGH
FRIDAY. NEXT WEEKEND WE WILL SEE THE WINDS PICK UP ALONG RIDGES AS
TEMPERATURES HOLD AROUND 15 DEGREES ABOVE SEASONAL AVERAGES.
OUR MAIN IMPACTS FROM THIS STRONG WARMING WILL BE A CONTINUED
REDUCTION IN SNOWPACK ACROSS THE SIERRA, WHICH WILL KEEP LOCAL
RIVERS AND STREAMS RUNNING COLD AND FAST. WHILE IT MIGHT BE TEMPTING
IN THIS HEAT TO COOL OFF IN THE RUSHING WATERS, WE ADVISE STEERING
CLEAR OF AREA RIVERS AND STREAMS. THE WATER WILL BE COLD ENOUGH TO
INDUCE SHOCK, AND FAST ENOUGH TO OVERWHELM EVEN A STRONG SWIMMER, SO
STAYING AWAY FROM RIVER BANKS IS ADVISED TO KEEP SAFE. WHILE THE
RIVERS AND STREAMS WILL BE RUNNING HIGH, NO FLOODING IS EXPECTED
AT THIS TIME.
ONCE THE RIDGE MOVES ON NEXT WEEKEND, OUR CHANCES FOR WINDY OR WET
WEATHER SHIFTS CLOSER TO THE REGION INTO NEXT WEEK. TEMPERATURES ARE
LOOKING TO STAY ABOVE AVERAGE (~10 DEGREES ABOVE AVERAGE), SO WE
DON'T EXPECT MUCH IN THE WAY OF WINTRY CONDITIONS RETURNING ANY
TIME SOON. HRICH
AVIATION
* LIGHT WINDS AND VFR CONDITIONS TODAY THROUGH THE WEEK. STRONG
WARMING WILL BRING DENSITY ALTITUDE CONCERNS TO THE REGION.
INVERSIONS IN VALLEYS WILL BRING REDUCTIONS TO SLANTWISE
VISIBILITY DUE TO HAZE BUILDING OVER THIS WEEK. HRICH
