COOLING AND BREEZY WINDS SAT-SUN WITH A WEAK FRONT.

WEEK WITH CONTINUED DRY CONDITIONS.

DISCUSSION
UNSEASONABLE WARMTH AND DRY CONDITIONS WILL BE THE MAIN STORY FOR
AT LEAST THE NEXT WEEK AS A SERIES OF PROGRESSIVELY STRONGER HIGH
PRESSURE SYSTEMS BUILD ACROSS THE WEST.
TEMPERATURES WILL WARM NEARLY 15F ABOVE AVERAGE TODAY-FRIDAY,
WITH MID-70S ACROSS W.NEVADA AND LOW/MID 60S FOR SIERRA VALLEYS.
THEN A MOSTLY DRY FRONT WILL BRUSH BY THE NEVADA-OREGON BORDER
RESULTING IN 3-6 DEGREES OF COOLING SATURDAY-SUNDAY.
BREEZY NORTHWEST WINDS WILL ACCOMPANY THE FRONT WITH GUSTS OF
20-30 MPH MAINLY NORTHWARD OF I-80 SATURDAY AFTERNOON BEFORE
WEAKENING AND BECOMING NORTHEAST TO EAST BY SUNDAY. ONLY A 15%
CHANCE FOR A LIGHT SHOWER IN E.MODOC CO SATURDAY AFTERNOON.
THEN AN UNSEASONBLY STRONG UPPER RIDGE WILL BEGIN TO BUILD NEXT
WEEK WHICH WILL LIKELY DELIVER RECORD MARCH TEMPERATURES. W.NEVADA
VALLEYS WILL WARM INTO THE LOW-MID 80S WITH SIERRA VALLEYS
SEEING LOW-MID 70S. THESE HIGH TEMPERATURES ARE MORE TYPICAL OF
EARLY TO MID JUNE OR ABOUT 20-25F ABOVE AVERAGE FOR MID-MARCH.
DAILY HIGH TEMPERATURES WILL LIKELY BE BROKEN DURING THE MONDAY-
FRIDAY TIMEFRAME NEXT WEEK WITH TUESDAY BEING TARGETED AS THE
WARMEST DAY OF THE WEEK. OUR CURRENT FORECASTED HIGH TEMPERATURE
ON TUESDAY FOR RENO (84F) WOULD SET AN ALL-TIME RECORD FOR THE
WARMEST MARCH DAY ON RECORD WHICH IS CURRENTLY 83F WHICH WAS SET
ON MARCH 31, 1966. WE'VE ALSO NEVER RECORDED 3 CONSECUTIVE DAYS IN
ROW WITH HIGH TEMPERATURES IN THE 80S IN RENO, BUT THAT RECORD
MAY BE IN PLAY AS WELL. ASIDE FROM THE WARMTH, THERE ARE NO REAL
PROSPECTS FOR PRECIPITATION IN THE NEXT 7-10 DAYS. FUENTES
AVIATION
VFR CONDITIONS PREVAIL THROUGH THE UPCOMING WEEK WITH AFTERNOON
WEST BREEZES WITH GUSTS 15-20 KT THURS-FRI. WINDS MAY THEN EDGE
UPWARD A BIT FOR SATURDAY WITH W-NW GUSTS AROUND 20 KT.
FOR NEXT WEEK, PREPARE FOR RISING DENSITY ALTITUDES AS AFTERNOON
HIGHS EXCEED 80 DEGREES AT WESTERN NV TERMINALS STARTING MONDAY.

HYDROLOGY
UNSEASONABLY MILD TEMPERATURES THROUGH THIS WEEKEND, FOLLOWED BY
LIKELY RECORD WARMTH NEXT WEEK WILL ACCELERATE SNOW MELT NEXT
WEEK. WHILE RIVERS WILL RUN FAST AND COLD, THEY ARE EXPECTED TO
REMAIN WELL BELOW FLOOD LEVELS. HOWEVER, THIS PREMATURE RUNOFF
WILL GREATLY REDUCE LATE SPRING TO EARLY SUMMER WATER SUPPLY
CONDITIONS. BARDSLEY/FUENTES
