Winter Storm in Utah, March 1 to 2, 2003

UTAH AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
255 AM MST SAT MAR 1 2003

.SYNOPSIS...A WEAK WINTER STORM WILL MOVE ACROSS THE AREA TODAY.
HIGH PRESSURE WILL PUSH INTO THE AREA SUNDAY AND REMAIN FOR MONDAY.

.DISCUSSION...DISORGANIZED STORM SYSTEM SLOWLY SPREADING INTO THE
AREA AND WILL LINGER THROUGH MUCH OF THE DAY ESPECIALLY OVER THE
SOUTH.  HOWEVER BECAUSE OF THE POOR ORGANIZATION WITH THE SYSTEM IT
LOOKS LIKE SNOWFALL AMOUNTS WILL BE ON THE LIGHT SIDE.  MODEL QPF
CONTINUES TO DECREASE WITH EACH RUN.  INSTABILITY OVER SOUTHWEST UT
BY MIDDAY WILL HELP A BIT THERE BUT IT STILL LOOKS UNLIKELY THAT WE
WILL GET ANY WIDESPREAD ADVISORY LEVEL ACCUMULATIONS.  SO PLAN TO
CANCEL THE ADVISORIES BUT STILL KEEP PROBABILITIES IN THE LIKELY
CATEGORY WITH GENERALLY 1-2 INCHES IN THE WESTERN VALLEYS AND 4 OR
LESS IN THE SOUTHERN MOUNTAINS.  ALL OF THIS DECREASES SLOWLY
FROM THE NORTH THIS AFTERNOON WITH ONLY SCATTERED ACTIVITY LEFT BY
EVENING AND THAT MAINLY IN THE SOUTH.

STILL HAVE A RIDGE TRYING TO BUILD INTO THE AREA SUNDAY BUT IT IS A
LITTLE SLOWER AND THE WARMING AT 700 MB IS SIGNIFICANTLY SLOWER
SPREADING ACROSS THE AREA. SO WILL GO A BIT COOLER IN THE SOUTH AND
THE MOUNTAINS SUNDAY THEN GENERALLY ABOUT 5 DEGREES WARMER MONDAY.

THE EXTENDED GETS A LITTLE MESSY.  TUESDAY HAS A TROF THAT HAS BEEN
SHEARING AS IT APPROACHES SLIDE ACROSS THE AREA WITH A NORTHWEST
FLOW.  NOT SURE WE WILL REALLY SEE MUCH MORE THAN CLOUDS WITH THIS
BUT THE AREAS OVER AND NEAR THE NORTHERN MOUNTAINS COULD GET A LIGHT
SNOW EVENT.  THEN BY WEDNESDAY THE FLOW TURNS MORE WESTERLY AS
ANOTHER TROF SETTLES SOUTHWARD ALONG THE BRITISH COLUMBIA COAST.
THAT FIRST BRINGS A LITTLE WARMER AIR INTO THE AREA WEDNESDAY WITH
SOMEWHAT LIMITED MOISTURE THEN STARTS PUSHING A SERIES OF IMPULSES
AND INCREASED MOISTURE EAST ACROSS THE AREA AS YET ANOTHER
SHORTWAVE...THIS ONE A MORE POLAR TYPE...PUSHES OFFSHORE ALONG THE
BC COAST. SO THURSDAY AND FRIDAY STILL LOOK QUITE UNSETTLED BUT
WITHOUT THE STRONG COOLING THAT HAD EARLIER BEEN INDICATED FOR
FRIDAY.

SLC 720 CDC 830 SANDERS

.SLC...SNOW ADVISORIES CANCELED.
