DISCUSSION
THROUGH THE WEEKEND.
OVERNIGHT SATELLITE IMAGERY SHOWS A LOW PRESSURE SYSTEM CHURNING
OVER THE GREAT BASIN WITH ISOLATED CONVECTION ACROSS THE
SOUTHEASTERN GREAT BASIN AND NORTHWESTERN ARIZONA. ISOLATED SHOWERS
AND THUNDERSTORMS WILL CONTINUE ACROSS THE EASTERN HALF OF OUR
FORECAST AREA TODAY, DRIVEN BY THE COLD FRONT ASSOCIATED WITH THE
AFOREMENTIONED LOW. LIGHT-TO-MODERATE RAIN, LIGHTNING, GRAUPEL, AND
ERRATIC WINDS WILL BE POSSIBLE WITH STORMS TODAY. IN ADDITION TO
SHOWERS AND THUNDERSTORMS, THIS COLD FRONT WILL ALSO BRING COOLER
THAN NORMAL TEMPERATURES TO THE REGION WITH THE FIRST FREEZES OF THE
SEASON EXPECTED IN THE SOUTHWESTERN GREAT BASIN EARLY THIS MORNING.
THE NORTHERN OWENS VALLEY WILL HAVE THEIR SHOT AT THEIR FIRST FREEZE
OF THE SEASON EARLY TOMORROW MORNING, AS LIGHTER WINDS AND CLEAR
SKIES ALLOW FOR STRONGER RADIATIONAL COOLING OVERNIGHT. GUSTY
NORTHWESTERLY WINDS WILL ALSO ACCOMPANY THIS FRONT. THE INYO,
ESMERALDA, AND CENTRAL NYE COUNTIES WILL SEE PEAK WIND GUSTS IN THE
30 TO 40 MPH RANGE WITH ISOLATED WIND GUSTS IN EXCESS OF 40 MPH
POSSIBLE IN AREAS OF HIGHER TERRAIN. ELSEWHERE, GUSTS WILL PEAK IN
THE 25 TO 35 MPH BEHIND THE COLD FRONT.
ON WEDNESDAY, THE AFOREMENTIONED LOW PRESSURE SYSTEM WILL MOVE OFF
TO OUR EAST, WITH BREEZY NORTH WINDS LINGERING DOWN THE COLORADO
RIVER VALLEY AND TEMPERATURES ACROSS THE REGION BEGINNING TO
GRADUALLY WARM BACK UP. A DISTURBANCE WILL SNEAK IN BEHIND THE
EXITING LOW ON THURSDAY, BRINGING ANOTHER ROUND OF GUSTY NORTH WINDS
TO THE REGION THURSDAY AFTERNOON THROUGH FRIDAY. THE STRONGEST OF
THESE WINDS ARE EXPECTED IN THE LOWER COLORADO RIVER VALLEY, WHERE
THE NBM BOASTS AN 80+ PERCENT CHANCE OF PEAK WIND GUSTS IN EXCESS
OF 40 MPH LATER THIS WEEK. WINDS WILL RELAX ON SATURDAY AND
SUNDAY, WITH TEMPERATURES RETURNING TO NEAR NORMAL OVER THE
WEEKEND.
