DISCUSSION
THROUGH SUNDAY.
UNSETTLED BUT FAIRLY LOW/NO-IMPACT CONDITIONS CONTINUE AS AN AREA OF
LOW PRESSURE SITS OFF THE CA COAST. A BREEZY AFTERNOON WITH GUSTS OF
15-25 MPH IS EXPECTED TODAY, FOLLOWED BY LIGHTER WINDS TUESDAY AND
WEDNESDAY. ISOLATED SHOWERS ARE POSSIBLE (~20%) THROUGH WEDNESDAY,
WITH BEST CHANCES ALONG AND SOUTH OF I-15 AS THE LOW PASSES TO OUR
SOUTH. ANOTHER SYSTEM MOVES IN ON THURSDAY, THIS TIME TRAVELING
SOUTHEAST FROM THE PACNW. THIS TRAJECTORY ISN'T THE MOST FAVORABLE
FOR WIDESPREAD NOR HEAVY PRECIPITATION, BUT THERE IS A SMATTERING OF
15-50% POPS ON THURSDAY, PRIMARILY ACROSS SOUTHEAST NV AND NORTHWEST
AZ. ANY PRECIPITATION THAT FALLS WILL LIKELY BE LIGHT, AS CHANCES
FOR MORE THAN 0.25" ARE LESS THAN 25% ACROSS THE AREA. THE BIGGEST
CONCERN WITH THURSDAY'S SYSTEM WILL BE THE NORTHWEST WINDS. AS
EXPECTED, CHANCES FOR IMPACTFUL WINDS HAVE INCREASED, NOW 30-60%
ACROSS MOST OF THE CWA. IF TRENDS CONTINUE, WIND HEADLINES WILL BE
NEEDED.
AS THE TROUGH PULLS AWAY ON FRIDAY, WE'LL BE LEFT UNDER DRY NORTH-
NORTHWESTERLY FLOW. THIS WILL KEEP NORTHERLY WINDS ELEVATED BUT SHUT
OFF ANY PRECIPITATION CHANCES. IT'LL ALSO USHER IN COLDER AIR,
PERHAPS THE COLDEST WE'VE SEEN THIS SEASON. IF WINDS SUBSIDE
OVERNIGHT, THE OUTSKIRTS OF THE LAS VEGAS VALLEY (PARTICULARLY THE
EAST SIDE) AND THE BARSTOW AREA MAY FLIRT WITH FREEZING SATURDAY
MORNING. CHANCES OF REACHING 32F CURRENTLY STAND AT 20-30%.
LOOKING BEYOND, GLOBAL ENSEMBLES SHOW A RIDGE BUILDING OVER THE
WESTERN US THIS WEEKEND, WHICH SHOULD CAUSE TEMPERATURES TO WARM
SUNDAY INTO NEXT WEEK.
