HYDROMETEOROLOGICAL DISCUSSION
NATIONAL WEATHER SERVICE / CALIFORNIA NEVADA RFC / SACRAMENTO CA
740 AM PST FRI MAR 6 2015

...DRY UNTIL NEXT MID-WEEK WITH LIGHT PRECIP NORTH OF I-80...

.24 HOUR PRECIPITATION TOTALS (ENDING MAR 6 AT 400 AM PST)...

HIGH PRESSURE OVER THE REGION RESULTED IN DRY CONDITIONS YESTERDAY.


.METEOROLOGICAL CONDITIONS (FRI AM - THU AM)...

UPR RIDGE IS CENTERED OVER NORTHERN CA...WHILE A VERY WEAK UPR LOW
IS DRIFTING EAST ACROSS NORTHERN BAJA THIS MORNING. THROUGH THE
WEEKEND...THE UPR RIDGE WILL MEANDER OVER THE AREA AND DRIFT
SLIGHTLY TOWARD THE WEST AND JUST OFFSHORE. EXPECT DRY AND WARM
CONDITIONS INTO EARLY NEXT WEEK.

FOR THE MIDDLE OF NEXT WEEK...AN UPR LOW CURRENTLY SPINNING OVER THE
EAST-CENTRAL PACIFIC (40N/150W) WILL EJECT A S/WV TROF TOWARD THE
PACNW AND NORTHERN CA. THE MODELS ARE SHOWING SOME DIFFERENCES WITH
THE HANDLING AND STRENGTH OF THIS SYSTEM. THE 06/00Z GEM IS THE
QUICKEST/STRONGEST/WETTEST...WHILE THE TREND OF THE GFS AND EC HAS
BEEN SLOWER/WEAKER/DRIER. FOR NOW...FOLLOWED CLOSER TO THE DRIER
SOLUTIONS. UNFORTUNATELY IT APPEARS THE HIGH PRESSURE WILL HOLD ON
STRONG ENOUGH TO ONLY BRING LIGHT PRECIP.


.HYDROLOGICAL CONDITIONS...

WITH VERY LITTLE PRECIPITATION IN THE FORECAST, MOST RIVER LOCATIONS
ARE EXPECTED TO SLOWLY RECEDE OVER THE NEXT FEW DAYS.  SOME VERY
SMALL RISES ARE EXPECTED IN HIGH ELEVATION WATERSHEDS DUE TO
SNOWMELT.

ALL FORECAST POINTS ARE EXPECTED TO REMAIN BELOW MONITOR STAGE FOR
THE NEXT FIVE DAYS.
