SYNOPSIS
 
 
A DRY COLD FRONT WILL PUSH THROUGH THE REGION TONIGHT INTO FRIDAY  
BRINGING BELOW NORMAL TEMPERATURES AND BREEZY NORTHERLY WINDS.  
RIDGING WILL START TO BUILD IN FOR THE WEEKEND INTO NEXT WEEK  
BRINGING WARMER AND DRY CONDITIONS. A FEW WEAK SYSTEMS MAY PASS TO  
THE NORTH, BRINGING A BIT OF COOLING AND PERIODS OF LIGHT BREEZES,  
BEFORE THE RIDGE REALLY STRENGTHENS OVER THE AREA THE MIDDLE OF  
NEXT WEEK.  
 

 
   
SHORT TERM...THROUGH SUNDAY NIGHT
 
 
A DRY COLD FRONT WILL DROP FROM THE NORTH TO SOUTHWEST THROUGH  
THE REGION TONIGHT INTO FRIDAY BRINGING SEVERAL DEGREES OF COOLING  
AND NORTH TO NORTHEASTERLY WINDS. THE INCREASING GRADIENT ACROSS  
SIERRA RIDGES FRIDAY AFTERNOON AND EVENING WILL LEAD TO STRONGER  
WINDS ACROSS SIERRA RIDGELINES, ESPECIALLY INTO ALPINE AND MONO  
COUNTIES. MOISTURE REMAINS IN EASTERN NEVADA WITH A CLEARLY  
DEFINED DRY SLOT PUSHING ACROSS THE SIERRA AND NORTHWEST NEVADA,  
SO NO PRECIPITATION IS EXPECTED FOR THE LOCAL REGION.  
 
FOR THE REMAINDER OF THE WEEKEND THE EASTERN PACIFIC RIDGE BUILDS  
IN ALONG THE WEST COAST, BUT NEVER FULLY SHIFTS INLAND IN THE  
SHORT TERM PERIOD. THIS WILL LEAD TO WARMER AND DRIER CONDITIONS  
ALONG WITH GENERALLY LIGHT WINDS. SATURDAY'S HIGH TEMPERATURES  
WILL BE TAPERED BY THE LOW LEVEL EASTERLY FLOW, BUT WITH WINDS  
TURNING MORE WESTERLY ON SUNDAY, HIGHS WILL CLIMB TO ABOUT 10  
DEGREES ABOVE NORMAL. -DAWN  
   
LONG TERM...MONDAY THROUGH THURSDAY
 
 
 
NO APPRECIABLE CHANGES WERE MADE TO THE LONG TERM FORECAST. A  
BACKDOOR COLD FRONT WILL BRING A BRIEF COOL-DOWN MON-TUES WITH  
INCREASED NORTHERLY FLOW. THEN, EASTERN PACIFIC RIDGING WILL BUILD  
BACK IN ALLOWING FOR A SIGNIFICANT WARMING TREND MID-TO-LATE WEEK TO  
AROUND 80 DEGREES FOR WESTERN NEVADA BY THURSDAY AFTERNOON. EXPECT  
RIVER FLOWS TO INCREASE REGION-WIDE, BUT ESPECIALLY ON THE CARSON  
AND WALKER RIVER SYSTEMS. IT WILL BE BEST TO STAY AWAY FROM THE  
RIVERBANKS THROUGH THE NEXT COUPLE OF MONTHS.  
 
OTHERWISE, THERE ARE INDICATIONS THAT A STRONGER WAVE WILL FLATTEN  
THE RIDGE BY THE END OF NEXT WEEK. THIS COULD OCCUR AS EARLY AS  
THURSDAY AFTERNOON, BUT HAVE KEPT MENTION OF PRECIPITATION OUT OF  
THE FORECAST UNTIL THERE IS BETTER RUN-TO-RUN MODEL CONSISTENCY.

AVIATION
 
 
LIGHTER WINDS ARE EXPECTED TODAY FROM THE NW WITH PEAK GUSTS TO  
25 KTS, STRONGEST NEAR KHTH, KNFL AND KLOL. PEAK SPEEDS WILL  
CONTINUE THROUGH 02Z TODAY BEFORE BECOMING LIGHT. LIMITED AREAS OF  
MTN WAVE TURBULENCE WITH IT BEING MODERATE AT BEST. THERE ARE  
SOME INDICATIONS THAT LOW-LEVEL MOISTURE MAY THICKEN INTO A THIN  
STRATUS DECK OVER TVL AND TRK EARLY FRIDAY MORNING.  
 
WINDS WILL BECOME MORE NORTHERLY ON FRIDAY AT SIMILAR SPEED, BUT VFR  
CONDITIONS AND LIGHT WINDS ARE EXPECTED THIS WEEKEND.
