AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1018 AM MST WED DEC 19 2007

.SYNOPSIS...A MOIST PACIFIC TROUGH WILL MOVE EAST OF THE AREA TODAY.
A STRONGER AND COLDER SYSTEM WILL SPREAD INTO THE AREA LATE TONIGHT
AND LINGER INTO FRIDAY. HIGH PRESSURE WILL FOLLOW FOR SATURDAY.

&&

.DISCUSSION...ONE LAST GASP OF INSTABILITY WITH THE UPPER TROF AXIS
IS KEEPING SHOWERS GOING OVER NRN UT THIS MORNING. THESE SHOULD BE
ENDING THIS AFTERNOON AS SHORT WAVE RIDGING BUILDS IN. HAVE DROPPED
THE HIGHLIGHTS FOR THE CACHE VALLEY AS PRECIP HAS TAPERED OFF AND
ANY ADDITIONAL SHOWERS WILL BE EITHER MIXED WITH RAIN OR SNOW
MELTING AS IT FALLS WITH NO ACCUMULATION. ALSO DROPPED THE PRICE
AREA AS WESTERLY RIDGETOP WINDS HAVE SHUT OFF PRECIP THERE.
PARED DOWN THE ADVISORY FOR THE MTNS TO END AT 11AM AS ANY LINGERING
PRECIP AFTER THAT WILL BE LIGHT AT BEST.

NEXT SYSTEM SPREADS WARM FRONTAL PRECIP INTO THE AREA AFTER
MIDNIGHT TONIGHT WITH VALLEY RAIN AND MTN SNOW. WE REMAIN IN THE WARM
SECTOR TOMORROW WITH A SHARP COLD FRONT EXPECTED RIGHT ABOUT COMMUTE
TIME TOMORROW AFTN/EVE. THIS WILL CHANGE VALLEY PRECIP TO SNOW AND
IT COULD BE HEAVY UNDER GOOD DYNAMIC LIFT ALONG THE FRONT.

VERY COLD AIR SPREADS IN BEHIND THIS FRONT AND KEEPS INSTABILITY
SNOW SQUALLS GOING INTO FRI AFTERNOON BEFORE STRONG WARMING ALOFT
CAPS THE INSTABILITY. THE LAKE COULD BECOME A PLAYER IN THIS
PATTERN WITH THE BEST CHANCE FOR A LAKE BAND DEVELOPING LATE THU
NIGHT AND LASTING TIL ABOUT NOON FRI.

EXPECT THIS TO BE PRIMARILY AN ADVISORY EVENT FOR MOST AREAS ALTHO
SOME MTN LOCATIONS N OF ABOUT PROVO THAT ARE FAVORED IN SWLY FLOW
COULD REACH 12HR WARNING AMTS DURING THE DAY THU. VALLEY AMOUNTS
COULD ALSO REACH WARNING LEVELS UNDER THE LAKE BAND IF IT DEVELOPS.
THOUGHTS AT THIS TIME ARE TO RE-ISSUE AN ADVISORY THIS AFTERNOON
FOR THE NRN MTN ZONES AS IT WILL GET GOING THERE BEFORE MORNING AND
HOLD OFF ON THE REMAINDER OF THE AREA FOR NOW.

UPDATED FORECASTS EARLIER TO ADJUST HEADLINES AND LOWER MOST VALLEY
POPS FOR TODAY. WILL SEND ANOTHER BRIEF UPDATE WHEN REST OF CURRENT
HIGHLIGHTS EXPIRE.

&&

.AVIATION...CEILINGS AT THE SLC TERMINAL WILL PERIODICALLY BE 6000FT
AGL OR LOWER THROUGH EARLY AFTERNOON...THEN RISE ABOVE 6000FT AFTER
20-21Z. VFR CONDITIONS ARE EXPECTED TO PREVAIL THROUGH THE REST OF
THE DAY WITH A 20 PERCENT CHANCE OF BRIEF MVFR IN RAIN SHOWERS. A
LIGHT LAKE BREEZE WIND IS EXPECTED AT SLC THIS AFTERNOON...WITH
ONSET BETWEEN 20-22Z. HOWEVER...THERE IS A 30 PERCENT CHANCE THAT
WINDS MAY REMAIN SOUTHERLY OR BECOME LIGHT AND VARIABLE.
