AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
319 AM PST THU MAR 5 2015

.SYNOPSIS...

HIGH PRESSURE WILL REMAIN OVER THE WEST INTO THE START OF NEXT
WEEK, CONTINUING THE WARMING TREND WITH VERY DRY CONDITIONS. LOW
PRESSURE MAY REACH THE CALIFORNIA COAST WITH PRECIPITATION
POSSIBLE BY THE MIDDLE OF NEXT WEEK.

&&

.SHORT TERM...

HIGH PRESSURE BUILDING OVER CALIFORNIA AND NEVADA THROUGH THE
WEEKEND WILL CONTINUE THE WARMING TREND WITH HIGHS RETURNING TO
ABOVE NORMAL TODAY, AROUND 60 DEGREES FOR LOWER ELEVATIONS AND
LOWER-MID 50S FOR SIERRA VALLEYS. BY SATURDAY, HIGHS ARE EXPECTED
TO REACH THE 60S ACROSS WESTERN NV AND IN VALLEYS NEAR THE SIERRA.

STRONG SUBSIDENCE UNDER THE RIDGE WILL CONTRIBUTE TO VERY DRY
CONDITIONS FOR THE NEXT FEW DAYS, ESPECIALLY IN HIGHER ELEVATIONS
WHERE SOME SITES HAVE ALREADY REPORTED SINGLE DIGIT HUMIDITY.
LITTLE TO NO CLOUD COVER AND LIGHT WINDS IN THIS DRY AIR MASS WILL
LEAD TO A FEW MORE COOL NIGHTS, ALTHOUGH AS EACH DAY BECOMES
WARMER, THE SUBSEQUENT NIGHTS WILL NOT BE QUITE AS CHILLY. MJD

.LONG TERM...SUNDAY THROUGH WEDNESDAY...

TEMPERATURES WILL REMAIN ABOVE NORMAL EARLY NEXT WEEK WITH HIGHS
IN THE LOWER VALLEYS OF NORTHEAST CALIFORNIA AND WESTERN NEVADA IN
THE MID 60S TO LOWER 70S SUNDAY THROUGH TUESDAY. DRY AIR WILL MAKE
FOR BIG DIURNAL SWINGS WITH COLD MORNINGS AND WARM AFTERNOONS
THROUGH TUESDAY.

ON WEDNESDAY, IT DOES LOOK LIKE MODEST MOISTURE (PWATS UP TO AROUND
ONE INCH OVER NORTHERN CALIFORNIA) GETS PULLED INTO NORTHERN CA/NV
WITH A WEAK LEAD WAVE IN ADVANCE OF AN UPPER LOW OVER THE EASTERN
PACIFIC. SINCE THE WAVE LOOKS LIKE IT WILL BE SQUEEZED/SHEARED INTO
FAST ZONAL FLOW OVER THE INTERIOR WEST, DYNAMICS MAY BE LIMITED.
HOWEVER, THE MOISTURE DEPTH/TRANSPORT CURRENTLY LOOKS SUFFICIENT TO
PUSH LIGHT PRECIPITATION OVER THE CREST, AT LEAST NORTH OF I-80.
GIVEN WEAK DYNAMICS AND THE SUBTROPICAL MOISTURE SOURCE, SNOW LEVELS
OVER NORTHEAST CALIFORNIA WEDNESDAY LOOK FAIRLY HIGH AT AROUND 7000
FEET.

BEYOND WEDNESDAY, THE AFOREMENTIONED UPPER LOW OVER THE EASTERN
PACIFIC IS PROGGED TO SLOWLY MEANDER ITS WAY TOWARDS THE COAST.
TIMING BECOMES VERY UNCERTAIN AS THE LOW GETS LOST UNDER RIDGING
OVER THE NORTHEAST PACIFIC/GULF OF ALASKA. IN ANY CASE, THE LOW
LOOKS RATHER WEAK, ALTHOUGH AT LEAST SOME PRECIPITATION IS POSSIBLE
FOR NORTHEAST CALIFORNIA AND WESTERN NEVADA. SNYDER

&&

.AVIATION...

A RIDGE OF HIGH PRESSURE DIRECTLY OVERHEAD WILL BRING LIGHT WINDS
AND VFR CONDITIONS THROUGH THE WEEKEND. SNYDER

&&

.REV WATCHES/WARNINGS/ADVISORIES...
NV...NONE.
CA...NONE.
