CURRENT INFRARED AND WATER VAPOR SATELLITE IMAGERY SHOWS RIDGING
OVER SOUTHERN NEVADA, SOUTHEASTERN CALIFORNIA, AND NORTHWESTERN
ARIZONA WITH A WEAK DISTURBANCE OFF THE COAST OF SOUTHERN
CALIFORNIA. THIS RIDGE IS RESPONSIBLE FOR THE DRY AND WARM WEATHER
OF THE PAST FEW DAYS, WHICH WILL CONTINUE THROUGH FRIDAY. CLOUD
COVER WILL INCREASE ACROSS THE REGION AS THE AFOREMENTIONED
DISTURBANCE OFF THE COAST OF SOUTHERN CALIFORNIA WEAKENS AND DRIFTS
THROUGH THE SOUTHWESTERN US. THESE CLOUDS WILL BE THE ONLY NOTICABLE
IMPACT FROM THIS DISTURBANCE DRIFTING OVERHEAD, WITH CLOUD COVER
DECREASING ON FRIDAY.
TEMPERATURES WILL COOL DOWN OVER THE WEEKEND, DECREASING AROUND 5 TO
10 DEGREES FROM FRIDAY TO SUNDAY WITH ADDITIONAL COOLING EXPECTED
EARLY NEXT WEEK. THIS WEEKEND COOLDOWN IS A RESULT OF A SHORTWAVE
ROLLING THROUGH THE NORTHWESTERN US, WHICH WILL KNOCK DOWN 500 MB
HEIGHTS OVER OUR FORECAST AREA. GIVEN THE DRY INLAND TRACK OF THIS
SYSTEM, PRECIPITATION CHANCES ARE LIMITED TO THE PANHANDLE OF
LINCOLN COUNTY WHERE THERE IS AROUND A 20% CHANCE OF PRECIPITATION.
AS THIS SHORTWAVE EJECTS INTO THE PLAINS, WE WILL FIND OURSELVES
UNDER NORTHWESTERLY FLOW ALOFT. THIS NORTHWESTERLY FLOW WILL LEAVE
THE DOOR OPEN FOR ADDITIONAL SYSTEMS TO DROP INTO THE AREA EARLY
NEXT WEEK, WHICH WILL RESULT IN ADDITIONAL COOLING AND THE POTENTIAL
FOR SOME BREEZIER WINDS.
