AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
910 PM PST WED FEB 4 2026
KEY MESSAGES
* SLIGHT CHANCE OF MOUNTAIN SHOWERS IN THE SOUTHERN AND WESTERN
PORTIONS OF OUR FORECAST AREA ON FRIDAY.
* WE WILL SEE A PATTERN SHIFT EARLY NEXT WEEK, WHICH WILL BRING
INCREASED CHANCES FOR PRECIPITATION, COOLER TEMPERATURES, AND
AN UPTICK IN WINDS TO THE REGION.
DISCUSSION
THE BLOCKY PATTERN OVER THE WESTERN CONUS WILL BEGIN TO BREAK DOWN
AS A PACIFIC TROUGH OF LOW PRESSURE DIGS AND COMBINES WITH THE LOW
PRESSURE SYSTEM CURRENTLY LOCATED OFF THE BAJA CALIFORNIA COAST.
THIS WILL BRING THE CHANCE FOR LIGHT PRECIPITATION, MAINLY IN THE
MOUNTAINS ABOVE 7000 FEET.
AFTER BRIEF RIDGING OVER THE WEEKEND, ANOTHER, STRONGER TROUGH MOVES
IN AND WILL BRING A BETTER CHANCE FOR PRECIPITATION, ALONG WITH
WINDIER CONDITIONS AND COOLER TEMPERATURES. THE GREATEST IMPACT FROM
PRECIPITATION WILL BE IN THE EASTERN SIERRA WHERE MOUNTAIN SNOW WILL
BE A CONCERN.
