AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
201 AM PDT TUE SEP 2 2014

.SYNOPSIS...
DRY CONDITIONS WILL CONTINUE THE NEXT SEVERAL DAYS. VERY WARM
TEMPERATURES TODAY WILL COOL A FEW DEGREES FOR MID WEEK AS LOW
PRESSURE MOVES INTO THE PACIFIC NORTHWEST.

&&

.SHORT TERM...

NO MAJOR CHANGES TO THE FORECAST. AFTERNOON HIGHS FOR TODAY WILL
WARM INTO THE LOW TO MID 90S ACROSS THE WESTERN NEVADA VALLEYS
WITH 80S FOR THE SIERRA. WINDS WILL INCREASE THIS AFTERNOON WITH
THE TYPICAL 20-30 MPH GUSTS OFF THE SIERRA INTO THIS EVENING.

LOW PRESSURE WILL MOVE THROUGH THE PACIFIC NORTHWEST AND NORTHERN
ROCKIES TUESDAY NIGHT AND WEDNESDAY. THIS WILL PROVIDE A FEW
DEGREES OF COOLING WITH AFTERNOON HIGHS IN THE 80S FOR THE LOWER
VALLEYS WITH 70S ACROSS THE SIERRA. OVERNIGHT LOWS WILL ALSO DIP
CLOSE TO FREEZING IN THE SIERRA VALLEYS. WINDS WILL SHIFT TO THE
NORTH AND NORTHEAST FOR TUESDAY NIGHT AND WEDNESDAY BUT REMAIN
LIGHT FOR WESTERN NEVADA STANDARDS.

SOME HAZE FROM THE NORTHERN CALIFORNIA WILDFIRES MAY WORK INTO
THE NORTHERN SIERRA AND NORTHWEST NEVADA FOR TUESDAY AND
WEDNESDAY. HOWEVER DO NOT THINK THE SMOKE WILL PRODUCE ANY
SIGNIFICANT REDUCTIONS TO AIR QUALITY AND VISIBILITY. BRONG

.LONG TERM...FRIDAY THROUGH TUESDAY...

THE UPPER TROUGH THAT DROPS THROUGH THE PACIFIC NORTHWEST MID-WEEK
WILL SPLIT OFF SOME ENERGY NEAR THE NORTHERN CALIFORNIA COAST THAT
WILL REMAIN OVER THE REGION INTO EARLY NEXT WEEK. THIS LOW PRESSURE
WILL KEEP TEMPERATURES NEAR OR SLIGHTLY ABOVE SEASONAL THROUGH THE
EXTENDED.

THERE STILL REMAINS A BIT OF UNCERTAINTY BEYOND FRIDAY, AS MODELS
YESTERDAY WERE SHOWING THE JET FURTHER SOUTH IN SOUTHERN CA/NV AND
BUILDING CONVECTION INTO THE SIERRA BY THE WEEKEND. LATEST GFS/ECMWF
RUNS HAVE BACKED OFF ON THE PRECIP CHANCES, BUT ARE NOW TRENDING THE
JET FURTHER NORTH AGAIN OVER RENO-TAHOE WITH DRY SOUTHWEST FLOW OVER
OUR FORECAST AREA. ENSEMBLES STILL SHOW QUITE A BIT OF SPREAD IN THE
HEIGHTS OVER CA/NV THIS WEEKEND AS WELL. WE INCREASED THE WINDS IN
THE EXTENDED TO MATCH LATEST DETERMINISTIC MODEL TRENDS. FOR NOW,
CHANCES FOR PRECIPITATION WILL REMAIN NEAR ZERO THROUGH EARLY NEXT
WEEK, BUT THIS WILL DEPEND HIGHLY ON WHERE THE LOW PRESSURE ENDS UP
THIS WEEKEND. HOON

&&

.AVIATION...
VFR CONDITIONS EXPECTED THROUGH TODAY WITH HIGH PRESSURE OVERHEAD. A
LIGHT HAZE IS POSSIBLE FROM WILDFIRE SMOKE IN NORTHERN CALIFORNIA
AND OREGON WITH MINIMAL REDUCTIONS IN VISIBILITY. WINDS THIS
AFTERNOON WILL INCREASE FROM THE WEST WITH GUSTS UP TO 20-25KTS
THROUGH THIS EVENING. A WEAK FRONT ON WEDNESDAY WILL SHIFT THE WINDS
FROM THE NORTH TO NORTHEAST. HOON

&&

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