DISCUSSION
THE LATEST RAP ANALYSIS OF THE UPPER AIR PATTERN SHOWS A WEST-
NORTHWESTERLY FLOW OVER THE CWA THIS MORNING AS AN UPPER LOW MOVES
INTO MT. GOING THROUGH TODAY AND TOMORROW, MODELS SHOW A
WESTERLY, ZONAL FLOW OVER THE CWA AS THE DEPARTING LOW MOVES
FURTHER EAST. DRY CONDITIONS ARE TO BE EXPECTED WITH THIS PATTERN
ALOFT TODAY AND FRIDAY. DAYTIME HIGH TEMPERATURES FOR THE AREA
WILL COOL A FEW DEGREES EACH DAY, BUT ARE FORECAST IN THE 70S AND
80S, WHICH IS STILL AROUND 5-10 DEGREES ABOVE SEASONAL NORMALS.
LIGHTER WINDS COMPARED TO THOSE EXPERIENCED ON WEDNESDAY ARE
FORECAST WITH TYPICAL AFTERNOON BREEZES.
OVER THE WEEKEND, MODEL GUIDANCE PROJECTS AN UPPER TROUGH MOVING
IN THE NW CONUS ON SATURDAY AND DEEPENING OVER THE GREAT BASIN ON
SUNDAY. THIS PATTERN WILL CAUSE A SERIES OF COLD FRONTS TO PASS
THROUGH THE REGION, WHICH WILL COOL TEMPERATURES AND ENHANCE WINDS.
DAYTIME HIGHS FOR THE REGION LOOK TO BE IN THE 60S AND 70S ON
SATURDAY BEFORE DROPPING DOWN TO THE 50S AND 60S ON SUNDAY (WHICH
IS AROUND 5-15 DEGREES BELOW NORMAL FOR THIS TIME OF THE YEAR).
NE CA AND W NV VALLEYS WILL SEE LOW TEMPERATURES IN THE MIDDLE
30S TO LOWER 40S RANGE ON SATURDAY NIGHT FOLLOWED BY THE LOWER TO
UPPER 30S RANGE ON SUNDAY NIGHT. OVERNIGHT LOW TEMPERATURES FOR
SIERRA COMMUNITIES ARE FORECAST IN THE UPPER 20S TO LOWER 30S ON
SATURDAY AND LOWER 20S TO LOWER 30S ON SUNDAY. AS FOR THE WINDS
INCREASING, THERE IS STILL SOME UNCERTAINTY BETWEEN MODELS IN
TIMING OF FRONTAL PASSAGES WHICH WOULD AFFECT SOME OF THE WIND
DETAILS. HOWEVER, THESE WINDS WILL BE OUT OF THE NORTH ON BOTH
DAYS AND HAVE POTENTIAL FOR GUSTS TO EXCEED 30 MPH (PARTICULARLY
ON SUNDAY). THIS COULD CAUSE TRAVEL AND MARITIME IMPACTS WITHIN
THE AREA, SO PLEASE WATCH FOR FURTHER UPDATES IN CASE A PRODUCT
SUCH AS A LAKE WIND ADVISORY NEEDS TO BE ISSUED FOR THE WEEKEND.
WHILE MOSTLY DRY CONDITIONS ARE ANTICIPATED ON SATURDAY AND
SUNDAY, THERE IS A LOW CHANCE (<15%) FOR A SHOWER OR TWO IN
EASTERN PERSHING AND CHURCHILL COUNTIES EARLY SUNDAY.
ON MONDAY AND GOING INTO THE MIDDLE OF NEXT WEEK, FORECAST
GUIDANCE HAS THE TROUGH MAKING ITS WAY FARTHER EAST WITH AN UPPER
RIDGE TRAILING IT. THIS WILL ALLOW FOR MORE DRY CONDITIONS AND A
WARMING TREND TO START. AREA HIGH TEMPERATURES CURRENTLY ARE
FORECAST TO RETURN TO THE 70S AND 80S BY AT LEAST WEDNESDAY. -078
AVIATION
VFR CONDITIONS ARE ANTICIPATED FOR ALL AREA TAF SITES TODAY AND
TONIGHT. DRY CONDITIONS ARE IN THE FORECAST AND AFTERNOON WINDS MAY
GUST UP AROUND 20-25 KTS. SIMILAR CONDITIONS ARE EXPECTED ON FRIDAY,
FOLLOWED BY INCREASING WINDS OVER THE WEEKEND DUE WITH A SERIES OF
COLD FRONT PASSAGES. -078
