High Wind in Utah, April 2, 2003

UTAH AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
241 AM MST WED APR 2 2003

CORRECTION TO ADD SNOW ADVISORY INFORMATION

.SYNOPSIS...STRONG SOUTHWEST FLOW EARLY TODAY WILL GIVE WAY TO A
COLD FRONT WHICH WILL MOVE ACROSS THE AREA TODAY.  UNSEASONABLY COOL
AND UNSETTLED WEATHER BEHIND THE FRONT WILL CONTINUE THROUGH THE
WEEKEND.

.DISCUSSION...OVERALL NOT A BIG CHANGE IN THINKING.  BIGGEST CHANGE
IS THAT THE GFS NOW PUSHES THE COLD FRONT INTO SOUTHERN UT NEAR OR
SLIGHTLY AHEAD OF THE MOVEMENT ACROSS THE NORTH.  GIVEN THE DEPTH OF
THE TROF ALONG THE COAST AND THE SHORTWAVE EJECTING EAST THROUGH THE
BOTTOM OF THE TROF THIS IS ENTIRELY REASONABLE AND WILL BE
ACCEPTED.  THE MAIN DIFFERENCE FOR THE FORECASTS IS THAT THE STRONG
WINDS WILL DECREASE IN THE SOUTHWEST VALLEYS BY AFTERNOON JUST LIKE
THE IN NORTHWEST.  SO WILL BE ADJUSTING THE WIND ADVISORY TIMING FOR
THE SOUTHWEST TO END AT MIDDAY.  MOUNTAIN WINDS HAVE NOT BEEN
TERRIBLY IMPRESSIVE SO FAR BUT AS THE JET SHIFTS INTO WESTERN UT
THIS MORNING AND THE FRONT APPROACHES ITS HARD TO BELIEVE THAT AT
LEAST THE RIDGES WONT GET VERY WINDY TOO.  SO WILL LEAVE THE
MOUNTAIN WARNINGS ABOUT AS THEY ARE EXCEPT TO KEEP THE WESTERN
UINTAS AND WASATCH PLATEAU GOING INTO THE AFTERNOON.

AS FAR AS PRECIP GOES IT VERY HARD TO SEE WHERE THE SOUTH CAN GET
MUCH MOISTURE.  WILL DROP MENTION OF PRECIP IN THE CDC AND KANAB
ZONES AND LOWER THE SEVIER VALLEY A BIT FOR TONIGHT BUT OTHERWISE
THE AFTERNOON PACKAGE LOOKS FINE. WILL DO A SNOW ADVISORY FOR THE
WASATCH RANGE FOR THIS AFTERNOON AND TONIGHT.

A SECONDARY SHORTWAVE MOVING PAST EARLY THURSDAY SHOULD KEEP SHOWERS
OVER THE NORTH THEN IT LOOKS LIKE QUITE A BIT OF A BREAK LATE
THURSDAY TO FRIDAY EVENING.  THE NEXT WELL ORGANIZED IMPULSE MOVES
ACROSS FRIDAY NIGHT/EARLY SATURDAY AND COULD SPREAD PRECIP SOUTH TO
CDC.  THEN COLD AND UNSETTLED THROUGH SUNDAY BEFORE A SHORTWAVE
RIDGE TAKES CONTROL MONDAY THROUGH WEDNESDAY.
