TODAY THROUGH WEDNESDAY.
A POTENT COLD FRONT IS CURRENTLY PUSHING SOUTHWARD THROUGH
SOUTHEASTERN CALIFORNIA AND SOUTHERN NEVADA THIS MORNING. GUSTY
NORTH WINDS HAVE REACHED THE LAS VEGAS VALLEY AS OF 2 AM PST. GUSTY
NORTH-NORTHWEST WINDS WILL CONTINUE THROUGH THE DAY TODAY AREAWIDE
AS A RESULT, WITH GUST SPEEDS BETWEEN 35 AND 45 MPH AND HIGHER
SPEEDS IN THE HIGHER TERRAIN. ADDITIONALLY, TEMPERATURES WILL DROP
BY 10-12 DEGREES COMPARED TO WEDNESDAY, BRINGING US MUCH CLOSER TO
SEASONAL NORMALS. THE SYSTEM ASSOCIATED WITH THIS COLD FRONT WILL
BEGIN TO PUSH EASTWARD ON FRIDAY, RESULTING IN A SLIGHT DECREASE IN
WIND SPEEDS. THAT SAID, GUST SPEEDS WILL CONTINUE TO RANGE BETWEEN
25 AND 35 MPH AREAWIDE, WITH OCCASIONAL HIGHER VALUES, PARTICULARLY
IN THE HIGHER TERRAIN AND ALONG NORTH-SOUTH ORIENTED VALLEYS. AS
THIS WEATHER SYSTEM PUSHES EASTWARD, A NORTHWESTERLY FLOW WILL SET
UP ALOFT. A SECONDARY SHORTWAVE WILL GLIDE SOUTHWARD ALONG THIS FLOW
BEFORE ULTIMATELY CLOSING OFF OVER SOUTHERN NEVADA ON SATURDAY. AS
THIS OCCURS, A 120KT 250 MB JET WILL PUSH SOUTHWESTWARD THROUGH OUR
FORECAST AREA, RESULTING IN STRONG NORTHEASTERLY WIND GUSTS ON
SATURDAY. AS A RESULT, ALL WIND ADVISORIES HAVE BEEN EXTENDED IN
TIME THROUGH 10 PM PST / 11 PM MST SATURDAY NIGHT. GUSTY NORTHERLY
WINDS WILL LIKELY LINGER ALONG THE COLORADO RIVER VALLEY INTO
SUNDAY, BUT WILL REASSESS THE NEED FOR ANY WIND-RELATED HEADLINES AS
WE GET CLOSER. THESE SYSTEMS WILL BE DRY, OUTSIDE OF VERY SLIGHT
POTENTIAL (5-10%) FOR LIGHT RAIN IN NORTHEASTERN LINCOLN COUNTY THIS
AFTERNOON.
RIDGING RETURNS TO THE DESERT SOUTHWEST LATE-WEEKEND INTO THE START
OF NEXT WEEK THANKS TO A GROWING HIGH PRESSURE OVER THE EASTERN
PACIFIC OCEAN. THIS RIDGE WILL RESULT IN DRY CONDITIONS, MOSTLY
SUNNY SKIES, AND TEMPERATURES CLIMBING BACK TO 8 TO 10 DEGREES ABOVE
SEASONAL NORMALS.
