AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
403 AM PDT FRI JUL 3 2026
KEY MESSAGES
* DRY CONDITIONS, BREEZY AFTERNOONS, AND GRADUALLY WARMING
TEMPERATURES ARE EXPECTED THROUGH LATE NEXT WEEK.
DISCUSSION
THROUGH NEXT THURSDAY.
LATEST WATER VAPOR IMAGERY AND 500 HPA RUC ANALYSIS INDICATES THE
SEEMINGLY EVER-PRESENT TROUGH THAT HAS LARGELY LIMITED OUR
TEMPERATURES OVER THE PAST WEEK HAS WEAKENED FURTHER DUE TO THE
INFLUENCE OF A WESTWARD-BUILDING RIDGE OVER THE SOUTHERN CONUS.
ENSEMBLES REMAIN IN GOOD AGREEMENT THAT RIDGING WILL CONTINUE TO
REASSERT ITSELF OVER THE DESERT SOUTHWEST AND SOUTHERN ROCKIES INTO
NEXT WEEK, YIELDING A CONTINUATION OF OUR STEADY WARMING TREND. THIS
GRADUAL INCREASE IN TEMPERATURES THROUGH NEXT WEEK WILL RESULT IN
WIDESPREAD MODERATE HEATRISK (LEVEL 2 OF 4) BY MONDAY AND TUESDAY,
WITH POCKETS OF MAJOR HEATRISK (LEVEL 3 OF 4) DEVELOPING WEDNESDAY
AND THURSDAY. IN ADDITION TO THE WARMING TEMPERATURES, AFTERNOON
BREEZES TO AROUND 15 TO 25 MPH WILL DEVELOP EACH DAY, MAINTAINING
HEIGHTENED FIRE DANGER. CONCERNS WILL BE ELEVATED OVER THE
INDEPENDENCE DAY WEEKEND, SO FOR THOSE WHO WILL BE OUTDOORS, IN
ADDITION TO STAYING AS COOL AND HYDRATED AS POSSIBLE, ENSURE
SPECIAL CARE IS TAKEN WHEN GRILLING OR USING SAFE-AND-SANE
FIREWORKS, AS ANY SPARK WILL BE A RISK FOR WILDFIRE. THE FORECAST
THROUGH LATE NEXT WEEK REMAINS DRY, HOWEVER LONG-RANGE ENSEMBLE
GUIDANCE INDICATES AN INFLUX OF MONSOONAL MOISTURE LATE NEXT WEEK
AND BEYOND, SO STAY TUNED.
