DISCUSSION
THROUGH NEXT WEEKEND.
THE LONG-DURATION AND RECORD-SHATTERING HEAT SPELL IS FINALLY
WINDING DOWN AS THE DOMINANT HIGH PRESSURE RIDGE ACROSS THE WEST
BEGINS TO BREAK DOWN. NONETHELESS, HIGH TEMPERATURES TODAY ARE
LIKELY AGAIN TO RIVAL DAILY RECORDS FOR MANY LOCALES. LAS VEGAS
HAS BROKEN OR TIED DAILY RECORD HIGHS FOR 11 DAYS IN A ROW NOW,
AND IF THE FORECAST PLAYS OUT AS EXPECTED, IT WILL EXTEND THE
STREAK TO 12 DAYS TODAY. SLIGHT COOLING WILL BEGIN MONDAY AS
HEIGHTS BEGIN TO DECLINE, BUT THE COOLING WILL BE SUBTLE, AND
ONLY AMOUNT TO 1-3 DEGREES COOLER THAN TODAY. MORE SUBSTANCIAL
COOLING WILL FOLLOW FOR TUESDAY ONWARD AS A COUPLE OF PACIFIC
TROUGHS TRAVERSE THE WEST AND SEND HEIGHTS BACK TO MORE
TRADITIONAL SPRINGTIME TERRITORY. IN FACT, BY FRIDAY, OUR FORECAST
HIGH FOR LAS VEGAS IS 73 WHICH, WOULD BE THE FIRST BELOW NORMAL
HIGH TEMPERATURE IN OVER 3 WEEKS.
AS THE PATTERN CHANGES AND TEMPERATURES COOL, BREEZY CONDITIONS
WILL OVERSPREAD MUCH OF THE REGION. STRONGEST WINDS ARE EXPECTED
ACROSS THE HIGHER TERRAIN AND WESTERN MOJAVE DESERT, PARTICULARLY
TUESDAY THROUGH THURSDAY AS THE STRONGER TROUGHS TRAVERSE THE
GREAT BASIN. PRECIPITATION CHANCES HAVE ALSO TICKED UPWARD ACROSS
THE SIERRA, SOUTHERN GREAT BASIN, AND NORTHWEST PLATEAU OF
NORTHERN ARIZONA AS A QUICK MOVING SHORTWAVE MOVES THROUGH THE
GREAT BASIN. MOST OF THE PRECIPITATION WILL BE INTERCEPTED BY THE
HIGHER TERRAIN, BUT EVEN PARTS OF THE NORTHERN MOJAVE DESERT MAY
SEE SOME LIGHT SHOWERS OR SPRINKLES TUESDAY NIGHT INTO WEDNESDAY.
