TODAY'S HIGH TEMPERATURES WILL BE NUDGED DOWNWARD FROM RECENT 100S
ACROSS WESTERN NEVADA VALLEYS, WITH UPPER 90S REPLACING THE 100S FOR

THE HEAT COMES BACK IN FORCE FOR THE REMAINDER OF THE WEEK INTO NEXT
WEEKEND. TRIPLE DIGITS WILL SURGE BACK ONTO THE MAP AND REMAIN IN
PLACE AT LEAST THROUGH SATURDAY FOR THE BASIN AND RANGE AND THE
SIERRA FRONT. FOR WEDNESDAY, A HEAT ADVISORY HAS BEEN ISSUED, AND AN
EXTREME HEAT WATCH FOR THURSDAY THROUGH SUNDAY MORNING. THE
OVERNIGHT LOWS WILL RANGE BETWEEN 60 AND 70 DEGREES, WHICH WILL
OFFER LITTLE TO NO RELIEF IN OVERNIGHT COOLING. MAKE SURE TO FOLLOW
HEAT SAFETY ADVICE THIS WEEK, IT WILL BE A HOT ONE.
TYPICAL AFTERNOON BREEZES RETURN TODAY, WITH SMOKE AND HAZE LOFTING
INTO THE REGION FROM FIRES BURNING ACROSS THE INTERMOUNTAIN WEST.

RANGING 15-20 MPH THERE MAY BE PERIODS OF ELEVATED FIRE WEATHER
CONCERNS.
THE WEEKEND MAY BE OUR FIRST OPPORTUNITY TO SEE SHOWERS ARRIVING

APPEAR FOR MONO AND MINERAL COUNTIES. HRICH
