AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1026 PM PDT THU JUL 10 2025
KEY MESSAGES
* HOT AND DRY CONDITIONS WILL LIKELY CONTINUE THROUGH THE WEEKEND
AND INTO EARLY NEXT WEEK AS RIDGING PERSISTS ACROSS THE REGION.
DISCUSSION
THIS AFTERNOON THROUGH THE MIDDLE OF NEXT WEEK.
BROAD RIDGING WILL REMAIN OVER THE FORECAST AREA INTO NEXT WEEK,
ALTHOUGH THE EXACT PLACEMENT AND INTENSITY OF THE RIDGE WILL VARY AT
TIMES. THROUGH THE WEEKEND, LONG-RANGE ENSEMBLES ARE IN AGREEMENT
THAT THE AREA OF HIGH PRESSURE WILL REMAIN CENTERED OVER SOUTHERN
CALIFORNIA, MAINTAINING SLIGHTLY ABOVE-NORMAL HEIGHT ANOMALIES
THROUGH SATURDAY. THIS WILL RESULT IN TEMPERATURES REMAINING ABOVE
NORMAL, ALONG WITH KEEPING LIGHT WINDS AND MAINLY CLEAR SKIES. BY
LATE IN THE WEEKEND AND EARLY NEXT WEEK, MODEL ENSEMBLES INDICATE
THAT THE RIDGE WILL SHIFT EASTWARD, WHICH IS EXPECTED TO INCREASE
TEMPERATURES BY A FEW DEGREES. PATCHY AREAS OF MAJOR HEATRISK LEVELS
RETURN SUNDAY AND MONDAY ACROSS THE MOJAVE DESERT, AND TO A LESSER
EXTENT IN THE COLORADO RIVER VALLEY. STARTING FROM TUESDAY ON,
HEIGHTS BEGIN TO FALL AS AN EASTERLY WAVE MOVING INTO EASTERN MEXICO
PUSHES THE RIDGE TO THE WEST. THIS WAVE MAY ALSO INTRODUCE SOME
MOISTURE IN THE AREA BY THE SECOND HALF OF THE WEEK, WHICH WOULD
ALSO HELP TO KEEP READINGS DOWN. THERE IS ALSO A LOW CHANCE FOR
PRECIPITATION ON WEDNESDAY ACROSS NORTHWEST ARIZONA, BUT CONFIDENCE
IS LOW ON IF AND WHERE RAIN MAY OCCUR.
