DISCUSSION
TODAY THROUGH MONDAY.
A CLOSED AREA OF LOW PRESSURE AND ASSOCIATED COLD FRONT WILL
CONTINUE TO PUSH SOUTHEASTWARD THROUGH OUR FORECAST AREA TODAY
BEFORE IT LIFTS EASTWARD OVER THE NEXT FEW DAYS. AS A RESULT,
EXPECT LIGHT SHOWER ACTIVITY, PARTICULARLY ACROSS SOUTHERN
NEVADA AND NORTHWESTERN ARIZONA. NOT EXPECTING MUCH IN THE WAY OF
MEASURABLE RAINFALL, BUT CAN'T RULE OUT A FEW HUNDRETHS WITH
SHOWER ACTIVITY OVER THE HIGHER TERRAIN. ALONG WITH THIS LIGHT
PRECIPITATION, MUCH COOLER TEMPERATURES USHERED INTO THE REGION
THIS MORNING. PIOCHE, NEVADA IN LINCOLN COUNTY AND TONOPAH, NEVADA
IN NYE COUNTY RECEIVED SOME LIGHT SNOWFALL THIS MORNING AS A
RESULT. OTHERWISE, THE REGION CAN EXPECT HIGH TEMPERATURES TODAY
BETWEEN 15 AND 20 DEGREES BELOW SEASONAL NORMALS. THE DAILY RECORD
COOL HIGH FOR LAS VEGAS IS IN JEOPARDY THIS AFTERNOON, WITH A
FORECAST HIGH OF 65 AND A STANDING RECORD COOL HIGH OF 66 DEGREES
OBSERVED IN 1981. GOLDFIELD, NEVADA OBSERVED A LOW TEMPERATURE OF
30 DEGREES THIS MORNING BEFORE WARMING UP ABOVE FREEZING AROUND 8
AM. AS A RESULT, THE FREEZE WARNING FOR ESMERALDA AND CENTRAL NYE
COUNTIES HAS BEEN ALLOWED TO EXPIRE ON TIME. TONIGHT INTO
WEDNESDAY MORNING, THERE IS A FREEZE WARNING FOR THE NORTHERN
OWENS VALLEY INCLUDING BISHOP AS WELL AS FOR LINCOLN COUNTY
INCLUDING PIOCHE AND CALIENTE.
AS THE AFOREMENTIONED CLOSED LOW PUSHES EASTWARD, IT WILL LEAVE
THE DESERT SOUTHWEST UNDERNEATH A NORTHWESTERLY FLOW ALOFT. A
VORTICITY LOBE WILL RIDE SOUTHEASTWARD ALONG THIS FLOW BEFORE
ULTIMATELY CLOSING OFF OVER NORTHERN BAJA / SOUTHEASTERN
CALIFORNIA / SOUTHWESTERN ARIZONA LATE-WEEK. THIS WILL RETURN
GUSTY NORTH WINDS TO THE REGION ON THURSDAY, WITH GUST SPEEDS
BETWEEN 30 AND 40 MPH AND LOCALLY HIGHER SPEEDS IN THE HIGHER
TERRAIN. THIS CLOSED LOW WILL REMAIN IN PLACE THROUGH THE WEEKEND
BEFORE WEAKENING AND PUSHING EASTWARD FOR THE START OF THE WORK
WEEK. THERE IS LOW CONFIDENCE AT THE MOMENT, BUT ENSEMBLE MEANS
SUGGEST THAT THE PLACEMENT OF THIS LOW WILL HELP TO USHER TROPICAL
MOISTURE INTO THE MOJAVE DESERT FROM HURRICANE SIMON (CURRENTLY
PROGGED TO TRAVEL UP THE GULF OF CALIFORNIA), WHICH WILL INTERACT
WITH AN ADDITIONAL INCOMING LONG-WAVE TROUGH EARLY NEXT WEEK. AS A
RESULT, THERE ARE CURRENTLY WIDESPREAD PRECIPITATION CHANCES
EARLY NEXT WEEK. STAY TUNED AS THIS FORECAST DEVELOPS AND
CONFIDENCE INCREASES THROUGH THE WEEK.
