DISCUSSION
THROUGH FRIDAY.
DANGEROUS HEAT WILL PERSIST ACROSS THE MOJAVE DESERT INTO NEXT WEEK
AS RIDGING REMAINS IN PLACE. WIDESPREAD MAJOR HEATRISK (LEVEL 3 OF
4) WILL CONTINUE ACROSS THE MOJAVE DESERT THROUGH MONDAY WITH
POCKETS OF EXTREME HEATRISK (LEVEL 4 OF 4) IN LOWER ELEVATIONS.

NORMAL, WITH LITTLE OVERNIGHT RELIEF IN PLACES LIKE DEATH VALLEY AND
LAS VEGAS WHERE OVERNIGHT LOW TEMPERATURES WILL BE 100+ AND 90+
DEGREES RESPECTIVELY. TEMPERATURES WILL DECREASE A FEW DEGREES EARLY
NEXT WEEK AS THE RIDGE SHIFTS OFF TO OUR EAST, BUT WILL QUICKLY
REBOUND AS THE RIDGE RETROGRADES BACK WEST, EVENTUALLY MOVING
DIRECTLY OVERHEAD LATE NEXT WEEK.
MOISTURE WILL DECREASE SLIGHTLY OVER THE WEEKEND AS WE FIND
OURSELVES UNDER MORE SOUTHWESTERLY FLOW ALOFT. THIS RELATIVE
DECREASE IN MOISTURE COMBINED WITH A LACK OF LIFTING OUTSIDE OF
DAYTIME HEATING WILL RESULT IN LULL IN CONVECTIVE ACTIVITY THE
REGION OVER THE WEEKEND. THE EXCEPTION IS FAR EASTERN MOHAVE COUNTY,
WHERE THERE IS A 10 TO 15% CHANCE OF AFTERNOON STORMS OVER THE
WEEKEND.

MAY PUSH SMOKE INTO KBIH, PRODUCING REDUCED VISIBILITIES AND LOWER
CIGS AT TIMES. CONVECTION ON SATURDAY WILL BE MUCH MORE ISOLATED AND
LESS IMPACTFUL COMPARED TO THE PAST FEW DAYS WITH THE HIGHEST
