AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
950 PM MST WED FEB 14 2007

.SYNOPSIS...A SERIES OF WEAK BUT MOIST SYSTEMS IN NORTHWESTERLY
FLOW WILL CROSS NORTHERN UTAH THURSDAY THROUGH FRIDAY. A RIDGE OF
HIGH PRESSURE WILL BUILD INTO THE REGION FOR THE WEEKEND.

&&

.DISCUSSION...STRATOCUMULUS CLOUDS SHIELD REMAINS FAIRLY EXTENSIVE
ALONG AND WEST OF THE MOUNTAIN SPINE OF UTAH ALL THE WAY SOUTH TO
MILFORD. RADAR AND CAMERAS ALSO SHOW POCKETS OF LIGHT SNOW CONTINUE
OVER THE NRN MTNS. THE CLOUDS SHOULD DISSIPATE SOMEWHAT AND THE
SNOW TAPERS OFF AFTER MIDNIGHT...BUT THE NEXT SURGE OF MOISTURE
TOPPING THE RIDGE ARRIVES ON THE NOSE OF A NORTHERLY JET TOMORROW
MORNING WITH A WARM ADVECTION STRONG NORTHWEST FLOW AT 700MB
BRINGING SOME OROGRAPHIC SUPPORT FOR PRECIP. NEW 00Z RUNS MOISTEN UP
THE AIRMASS BY MID MORNING AND EXPECT AT LEAST A CHANCE OF PRECIP
AS FAR SOUTH AS PROVO BEFORE NOON...WITH A BETTER CHANCE AS THE DAY
GOES ON. THE SOUTHERN EXTENT OF THE PRECIP WILL PROBABLY BE ABOUT
CENTRAL UT BUT CLOUDS WILL PROBABLY REACH CEDAR CITY.

THIS BASIC PATTERN LASTS INTO FRIDAY WHEN A STRONGER SHORT WAVE
RIPPLING PAST INTO THE NRN PLAINS SENDS A LOW LEVEL COLD FRONT INTO
UTAH...BRINGING A MORE STABLE AIRMASS.

RIDGING THIS WEEKEND IS SHORT LIVED IN THE LATEST GFS...ONLY SAT
AFTERNOON AND EVE...WITH MOISTURE SPREADING BACK INTO THE STATE ON A
STRONG SOUTHWEST FLOW ON SUN. THE UPSTREAM TROF CLOSES OFF INTO AN
UPPER LOW OVER CA MON THEN DROPS SEWD AND CROSSES AZ TUE. THIS WILL
RESULT IN A DISORGANIZED EVENT FOR UT WITH THE BEST THREAT OF
PRECIP DOWN SOUTH.

UPDATED FORECASTS TO BRING PRECIP IN SOONER TOMORROW AND BOOST POPS
SOMEWHAT OVER NRN AND CENTRAL UT. ALSO INCREASED CLOUD COVER SAME
AREA. REST OF FORECAST LEFT UNCHANGED.

&&

.AVIATION...CEILINGS ARE EXPECTED TO REMAIN AT OR ABOVE 7000FT AGL
THROUGH 10-12Z. THERE IS ALSO A 40 PERCENT CHANCE DRAINAGE WINDS
WILL FAIL TO DEVELOP TONIGHT. WITH THE NEXT DISTURBANCE MOVING
EASTWARD...THERE IS A 20 PERCENT CHANCE LIGHT PRECIPITATION WILL
DEVELOP BETWEEN 08-11Z. IF THIS DOES OCCUR...A BRIEF PERIOD OF SNOW
WITH IFR CONDITIONS IS POSSIBLE BEFORE THE CHANGEOVER TO RAIN.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...NONE.
WY...NONE.
