AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
1230 AM PST SUN DEC 7 2025
KEY MESSAGES
* DRY WEATHER WITH WARMER THAN NORMAL TEMPERATURES EXPECTED
THROUGHOUT THE WEEK.
* A WETTER PATTERN MAY ARRIVE AROUND AND AFTER THE MIDDLE OF
DECEMBER, BUT CONFIDENCE REMAINS LOW.
DISCUSSION
A PERSISTENT BLOCKING PATTERN WILL KEEP THE REGION DRY THROUGHOUT
THE WEEK AND INTO THE FOLLOWING WEEKEND. TEMPERATURES THIS WEEK
WILL REMAIN WARMER THAN NORMAL, BUT ADDITIONAL WARMING AFTER
MONDAY WILL YIELD DAYTIME HIGHS IN THE UPPER 50S TO MID 60S FROM
TUESDAY ONWARD -- WHICH IS ABOUT 15 TO 20 DEGREES ABOVE SEASONAL
AVERAGES. STOUT INVERSIONS WILL LIKELY RESULT IN HAZY SKIES ACROSS
LOWER VALLEYS EACH MORNING THIS WEEK, BUT HAZE SHOULD DISPERSE IN
THE AFTERNOONS.
TUESDAY INTO WEDNESDAY PRESENTS THE SOLE OPPORTUNITY FOR SHOWERS
THIS WEEK, AND EVEN THEN, CHANCES ARE ONLY UP TO 30% AND CONFINED TO
AREAS NEAREST TO THE OREGON BORDER. ENSEMBLES CONTINUE TO ADVERTISE
A SHIFT TOWARDS A WETTER PATTERN -- AT LEAST TO SOME EXTENT --
DURING THE WEEK OF DECEMBER 15TH. HOWEVER, TRENDS AREN'T INSTILLING
MUCH CONFIDENCE AS PRECIPITATION TIMING AND INTENSITY CHANGE WITH
EACH NEW ITERATION. IN OTHER WORDS, IT'S INCREASINGLY LIKELY WE'LL
FINALLY SHAKE THIS BLOCKING PATTERN AROUND MID-DECEMBER, BUT THE
STRENGTH AND TIMING OF ANY WINTER STORMS THAT FOLLOW AS A RESULT ARE
UNCERTAIN.
