AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1005 AM MST THU FEB 5 2009

.SYNOPSIS...SOUTHERLY FLOW WILL INCREASE ACROSS THE REGION TODAY.
A PACIFIC STORM SYSTEM WILL MOVE ACROSS THE AREA TONIGHT AND
FRIDAY. ADDITIONAL SYSTEMS WILL CROSS THE REGION OVER THE WEEKEND
AND INTO NEXT WEEK.

&&

.DISCUSSION...DESPITE THE LOW PRESSURE SYSTEM STILL OFF THE
SOUTHERN CALIFORNIA COAST HIGH LEVEL MOISTURE HAS SPREAD RAPIDLY
ACROSS THE REGION MAKING SKIES CLOUDY OR MOSTLY CLOUDY ALREADY.
THERE ARE SOME BREAKS OVER SOUTHERN CALIFORNIA AND ARIZONA SO HAVE
UPDATED THE FORECAST TO ALLOW THE EAST AND SOUTH CENTRAL TO REMAIN
PARTLY CLOUDY THROUGH TODAY. ELSEWHERE MODELS INDICATE THAT MOSTLY
CLOUDY CONDITIONS SHOULD PREVAIL. THIS CLOUD COVER WILL HAVE AN
IMPACT ON MAXIMUM TEMPERATURES AS AREAS BELOW THE INVERSION MAY
END UP BEING COOLER THAN YESTERDAY WHILE ON THE OTHER HAND AREAS
ABOVE THE INVERSION SHOULD MIX WELL AND SEE MILD TEMPERATURES ONCE
AGAIN. THE CURRENT FORECAST LOOKS ON TRACK WITH THIS SCENARIO SO
HAVE NOT MADE ANY CHANGES.

THE GFS AND NAM BOTH SHOW THAT PRECIPITATION IS NOT LIKELY TO
OCCUR UNTIL AFTER MIDNIGHT WHICH IS MUCH LATER THAN THE EARLIER
FORECAST HAD. HAVE UPDATED THE POPS AND WEATHER FOR THE EVENING
PORTION OF THE NIGHT TO DELAY IT UNTIL AFTER MIDNIGHT.

AS THIS SYSTEM GETS KICKED NORTHEAST IT WILL HAVE ENOUGH COLD AIR
WITH IT ON FRIDAY TO ERODE THE VALLEY INVERSIONS. ALTHOUGH THERE
IS A WEAK COOL FRONT ASSOCIATED WITH THIS SYSTEM PRECIPITATION IS
EXPECTED TO BE SPOTTY AND LIGHT IN THE VALLEYS WITH MORE
SIGNIFICANT PRECIP LIKELY IN THE MOUNTAINS. LEANING TOWARDS SOME
WINTER STORM HIGHLIGHTS IN THE AFTERNOON PACKAGE THAT COULD GO
THROUGH MONDAY OR TUESDAY.

&&

.AVIATION...LIGHT NORTHERLY SURFACE WINDS ARE EXPECTED TO CONTINUE
AT THE SLC TERMINAL WITH A 30 PERCENT CHANCE THAT WINDS WILL RETURN
TO SOUTHERLY THROUGH 21Z. WINDS ABOVE THE SURFACE WILL REMAIN OUT OF
THE SOUTH-SOUTHWEST AND INCREASE THROUGHOUT THE DAY. CEILINGS
WILL REMAIN ABOVE 7000FT AGL UNTIL AT LEAST 06Z.
