AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1053 AM PDT SAT APR 4 2026
KEY MESSAGES
* GUSTY CONDITIONS WILL LINGER IN THE LOWER COLORADO RIVER VALLEY
TODAY.
* WARMER AND CALMER CONDITIONS DEVELOP OVER THE NEXT SEVERAL DAYS
BEFORE A MID-WEEK SYSTEM BRINGS ANOTHER SHOT OF GUSTY WINDS AND
COOLER TEMPERATURES.
DISCUSSION
TODAY THROUGH THURSDAY.
THE SYSTEM THAT BROUGHT THE COOLER TEMPERATURES AND GUSTY NORTH
WINDS WILL CONTINUE TO EXIT THE AREA AS HIGH PRESSURE BUILDS OVER
THE WESTERN US. MOST OF THE REGION WILL SEE LIGHTER WINDS ALONG WITH
TEMPERATURES INCREASING AROUND 5 TO 10 DEGREES. THERE WILL BE ENOUGH
OF A SURFACE GRADIENT REMAINING DOWN THE LOWER COLORADO RIVER VALLEY
TO KEEP SOME ENHANCED NORTHERLY WINDS THROUGH MUCH OF THE DAY. NORTH
WINDS 10 TO 20 MPH WILL BE COMMON WITH GUSTS TO AROUND 35 MPH
GENERALLY SOUTH OF LAKE MOHAVE. WINDS WILL BE STRONGEST THROUGH NOON
BEFORE TAPERING OFF DURING THE AFTERNOON. A LAKE WIND ADVISORY WILL
BE IN EFFECT THROUGH 5PM TODAY WITH THE POTENTIAL OF SEEING WAVE
HEIGHTS OF 1 TO 3 FEET. AGAIN, MAIN CONCERNS DURING THIS TIME PERIOD
ARE HAZARDOUS BOATING CONDITIONS. BY SUNDAY, THE RISK OF ANY WIND
IMPACTS ACROSS THE REGION IS MINIMAL.
HIGH PRESSURE WILL REMAIN IN PLACE INTO EARLY NEXT WEEK WITH
TEMPERATURES CLIMBING EACH DAY. HIGH TEMPERATURES BY TUESDAY ARE
EXPECTED TO BE AROUND 10 DEGREES ABOVE NORMAL. THE ONE WRINKLE IN
THE FORECAST DURING THIS TIME IS A WEAK DISTURBANCE THAT MODELS SHOW
SNEAKING UNDER THE RIDGE ON MONDAY. WHILE WEAK, GUIDANCE SUGGESTS IT
WILL HAVE ANOMALOUS MOISTURE TO WORK WITH, ENOUGH SUCH THAT THE NBM
HAS 10-20% POPS OVER NW ARIZONA. BEST CHANCES REMAIN OVER
CENTRAL/EASTERN ARIZONA, BUT CANNOT RULE OUT A FEW SHOWERS IN
EASTERN MOHAVE COUNTY MONDAY AFTERNOON.
AS WE MOVE TOWARD THE END OF THE NEXT WEEK, THE LATEST GUIDANCE HAS
BEEN FAIRLY CONSISTENT IN SHOWING A MORE ROBUST AND COMPLICATED
SYSTEM(S) MOVING INTO THE WESTERN US. DETAILS REMAIN FUZZY AT THIS
TIME, BUT ANOTHER SHOT OF GUSTY WINDS AND COOLER TEMPERATURES
APPEARS LIKELY AT THIS TIME, WITH PRECIPITATION CHANCES MORE
QUESTIONABLE.
