AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
252 PM PST SAT FEB 6 2016

.SYNOPSIS...

HIGH PRESSURE WILL BUILD OVER THE GREAT BASIN, KEEPING DRY
CONDITIONS IN PLACE WITH GENERALLY LIGHT WINDS AND VALLEY
INVERSIONS. A STEADY TREND IS EXPECTED WITH DAYTIME TEMPERATURES
WARMING WELL ABOVE NORMAL THROUGH THE UPCOMING WEEK. A WEAK STORM
SYSTEM MAY BRING LIGHT RAIN AND SNOW BY NEXT WEEKEND.

&&

.SHORT TERM...

HIGH PRESSURE CONTINUES TO BUILD OVER THE REGION OVER THE NEXT FEW
DAYS WITH LIGHT WINDS AND DRY CONDITIONS. TEMPERATURES WILL
CONTINUE TO WARM, GRADUALLY RISING INTO THE UPPER 50S BY EARLY
NEXT WEEK. TEMPERATURES WILL BE ABOVE NORMAL, BUT ARE NOT EXPECTED
TO REACH RECORD HIGHS THROUGH THE SHORT TERM. MOSTLY CLEAR SKIES
TONIGHT WILL LEAD TO STRONG COOLING AND PATCHY FREEZING FOG IN THE
VALLEYS OF THE NORTHERN SIERRA TONIGHT AND INTO SUNDAY MORNING.
VALLEY INVERSIONS WILL LIMIT MIXING OVER THE NEXT COUPLE DAYS
WITH RESULTING IN POOR AIR QUALITY IN GENERAL AND POOR VENTILATION
PRESCRIBED BURNING OPERATIONS. AS TEMPERATURES CONTINUE TO
INCREASE, RUNOFF WILL INCREASE ON AREA RIVERS AND STREAMS.
A SURFACE HIGH OVER THE GREAT BASIN NEXT WEEK WILL INCREASE
EASTERLY GRADIENT WINDS OVER THE SIERRA CREST, BUT NOT EXPECTED TO
BE TOO STRONG IN THE VALLEYS. SOME RIDGE TOP GUSTS COULD APPROACH
40 MPH ESPECIALLY IN MONO COUNTY AND COULD IMPACT RECREATIONAL
OUTDOOR AND BACK COUNTRY ACTIVITIES. HOON


LONG TERM...WEDNESDAY THROUGH SATURDAY...

DRY AND MILD PATTERN WILL CONTINUE FOR THE SECOND HALF OF NEXT WEEK
WITH HIGH PRESSURE IN CONTROL OVER THE REGION. HIGH TEMPERATURES
WILL REMAIN OVER TEN DEGREES ABOVE SEASONAL AVERAGES WITH LOWER
60S EXPECTED ACROSS WESTERN NEVADA AND MID 50S FOR SIERRA VALLEYS
THROUGH FRIDAY. HIGH PRESSURE WILL ALSO KEEP WINDS LIGHT EXCEPT
FOR SOME BREEZY CONDITIONS ACROSS THE RIDGE TOPS ON WEDNESDAY AND
FRIDAY AS WEAKER SYSTEMS PASS BY TO THE NORTH. FRIDAY`S SYSTEM
LOOKS TO BE THE ONLY POTENTIAL TO SEE SOME LIGHT PRECIPITATION,
BUT AMOUNTS CONTINUE TO LOOK MEAGER AS THE BLOCKING RIDGE DEFLECTS
THE SYSTEM NORTHWARD. THE MAIN CHANGE WITH THIS SYSTEM WILL BE A
COOL DOWN OF ABOUT 5-7 DEGREES WITH MID 50S POSSIBLE FOR WESTERN
NEVADA AND UPPER 40S ACROSS THE SIERRA BY NEXT SATURDAY. FUENTES

&&

.AVIATION...

HIGH PRESSURE BUILDING INTO THE SIERRA AND NORTHWEST NEVADA WILL
BRING WIDESPREAD VFR CONDITIONS ALONG WITH LIGHT SURFACE WINDS, AND
15 TO 25 KT RIDGE LEVEL WINDS THROUGH THE WEEKEND. RIDGE LEVEL WINDS
DO INCREASE IN MONO COUNTY LATE SUNDAY INTO MONDAY WITH SOME GUSTS
AROUND 35/40 KTS. MID AND HIGH LEVEL CLOUDS WILL DECREASE
OVERNIGHT WHICH MAY ALLOW FOR FREEZING FOG FORMATION AROUND KTRK
AND THROUGH THE MARTIS AND SIERRA VALLEYS INTO SUNDAY MORNING.
