AREA FORECAST DISCUSSION

SYNOPSIS
 
 
A COLD FRONT CROSSED THE REGION EARLY THIS MORNING ACCOMPANIED  
BY SCATTERED SHOWERS. MUCH COOLER AND DRIER AIR FOLLOWS FOR  
TODAY WITH TEMPERATURES RUNNING BELOW NORMAL INTO THE FIRST  
PART OF THE WORK WEEK. FAST MOVING DISTURBANCES WILL BRING  
PERIODS OF SHOWERS MIXED WITH DRY PERIODS TUESDAY NIGHT THROUGH  
THURSDAY. TEMPERATURES WILL MODERATE TOWARDS THE SECOND HALF OF  
THE WEEK.  
 

 
   
NEAR TERM /THROUGH TODAY/
 
 
THE SECONDARY COLD FRONT AND ANY LEFTOVER SHOWERS WILL QUICKLY SWEEP  
OFFSHORE IN THE PREDAWN HOURS THIS MORNING. BEHIND IT...A GUSTY  
NORTHWEST POST-FRONTAL WIND AND MOSTLY SUNNY SKIES. TEMPERATURES  
TODAY WILL AVERAGE BELOW NORMAL WITH HIGHS RANGING FROM 55 TO  
60 ACROSS THE MOUNTAINS AND IN THE 60S ELSEWHERE. GIVEN THE  
GUSTY NORTHWEST WINDS AND TEMPERATURES IN THE 60S I'VE GONE  
AHEAD AND ISSUED AN SPS FOR INLAND COLD WATER AS WATER  
TEMPERATURES REMAIN BELOW 60 ON MOST BODIES OF WATER. A BEACH  
HAZARDS STATEMENT HAS BEEN ISSUED ALONG THE COAST.  
 

 
   
SHORT TERM /TONIGHT THROUGH 6 PM MONDAY/
 
 
A CLEAR START TONIGHT WITH DIMINISHING WIND AND A DRY AIRMASS IN  
PLACE WILL SPELL SOME SCATTERED FROST ACROSS THE NORMALLY COLDER  
INTERIOR VALLEYS. HOWEVER...THE NEXT SHORTWAVE IMPULSE AND UPPER  
TROUGH WILL BE APPROACHING OVERNIGHT BRINGING INCREASING CLOUDS.  
GIVEN THE SHORT NIGHT AND INCREASING CLOUD COVER...I'VE HELD  
OFF ON ISSUING A FROST ADVISORY SINCE SOME UNCERTAINTY REMAINS  
ON HOW WIDESPREAD THE FROST POTENTIAL WILL BE. ALONG WITH THE  
CLOUDS WILL BE THE CHANCE OF A FEW SPRINKLES OR FLURRIES ACROSS  
THE HIGHER TERRAIN LATE TONIGHT. LOWS WILL RANGE FROM THE MID  
30S TO AROUND 40...WITH SOME LOWER 30S POSSIBLE IN THE NORMALLY  
COLDER MOUNTAIN VALLEYS. ON MONDAY...PASSAGE OF THE UPPER TROUGH  
COMBINED WITH DAYTIME HEATING SHOULD PROVIDE A MIX OF CLOUDS AND  
SUNSHINE ALONG WITH THE CHANCE OF A PASSING SHOWER. HIGHS WILL  
BE IN THE 50S ACROSS THE MOUNTAINS WILL LOWER AND MID 60S  
ELSEWHERE.  
 

 
   
LONG TERM /MONDAY NIGHT THROUGH SATURDAY/
 
 
ON TUESDAY WE WILL BE IN SW FLOW ALOFT, TRANSITIONING TO WESTERLY  
FLOW WEDNESDAY INTO THURSDAY. BY FRIDAY. NEAR ZONAL FLOW WILL HAVE  
SET UP. WITHIN THESE QUICK CHANGES, SHORT WAVES IN THE FLOW WILL  
BRING SEVERAL CHANCES OF PRECIPITATION.  
 
BERMUDA HIGH WILL BE SUPPRESSED TO THE SOUTH BY MIDWEEK WTH LOW  
PRESSURE STRENGTHENING AND RETROGRADING FROM NEAR NOVA SCOTIA  
TO EASTERN QUEBEC. THE FLOW BECOMES MORE CHAOTIC AFTER THIS, AND  
AS SUCH CONFIDENCE IN ANY PARTICULAR WAVE/PRECIP EVENT WILL BE  
MODERATE AT BEST.  
 
THE BEST CHANCE FOR MEASURABLE PRECIP COMES TUESDAY NIGHT INTO  
WEDNESDAY WITH A FRONTAL SYSTEM CROSSING THE AREA. QPF LOOKS TO  
BE ON THE LIGHT SIDE. SW FLOW ALOFT/WEST SIDE OF THE UPPER LOW  
WILL PREVAIL THURSDAY INTO FRIDAY. THIS MEANS MORE CLOUD COVER  
FOR THE NORTH AND A CHANCE OF MOUNTAIN SHOWERS.  
 
AFTER A COOL START TO THE WEEK, HIGHS WARM INTO THE UPPER 60S TO  
NEAR 80. AFTER A FROPA ON THURSDAY, TEMPERATURES WILL DROP BACK DOWN  
A FEW DEGREES.
