AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
945 PM MDT MON MAR 23 2015

.SYNOPSIS...THE NEXT STORM SYSTEM WILL CROSS MAINLY NORTHERN UTAH
AND SOUTHWEST WYOMING ON TUESDAY. STRONG HIGH PRESSURE ALOFT WILL
RETURN FOR THE LATTER HALF OF THE WEEK.

&&

.DISCUSSION...THE SHORTWAVE TROUGH ASSOCIATED WITH THE LATEST ROUND
OF WEATHER IS STILL SITUATED OVER NORTHERN UTAH...BUT IS QUICKLY
EXITING WITH THE TROUGH AXIS PROGGED TO BE EAST OF THE AREA SHORTLY
AFTER MIDNIGHT. MEANWHILE...THE SURFACE COLD FRONT IS CURRENTLY
DRAPED FROM JUST SOUTH OF MILFORD TO AROUND HANKSVILLE. THE FRONT IS
EXPECTED TO SAG A BIT FARTHER SOUTH BEFORE WEAKENING OVERNIGHT.

SUBSIDENCE AND WARMING TEMPERATURES ALOFT BEHIND THE TROUGH AXIS IS
ALREADY BRINGING AN END TO THE SHOWERS ACROSS WESTERN UTAH...ALONG
WITH CLEARING SKIES. EXPECT A FEW LINGERING SHOWERS FOR A FEW MORE
HOURS ACROSS THE NORTHEASTERN ZONES AND NEAR THE FRONTAL BOUNDARY.
STILL SEEING LOCALLY GUSTY WINDS ON BOTH SIDES OF THE FRONT BUT
THESE WINDS ARE EXPECTED TO WEAKEN THROUGH THE NIGHT.

OVERNIGHT TEMPERATURES WILL BE COOLER TONIGHT ACROSS MANY AREAS
COMPARED TO THE LAST FEW DAYS DUE TO THE COOLER AIRMASS AND A WINDOW
OF MOSTLY CLEAR SKIES. CLOUDS SHOULD FILL IN AGAIN AT LEAST ACROSS
THE NORTH LATE TONIGHT AS H7 WARM ADVECTION STRENGTHENS.
PRECIPITATION WILL THEN BEGIN TO FILL IN NEAR THE IDAHO BORDER
BEFORE THE NEXT COLD FRONT PUSHES THROUGH THE STATE TOMORROW
AFTERNOON AND EVENING. FAIRLY DECENT COLD ADVECTION WILL EXIST TO
SUPPORT A PERIOD OF PRECIPITATION...BUT THE BULK OF THE UPPER
SUPPORT WILL REMAIN NORTH OF THE AREA WHICH WILL SERVE TO LIMIT
PRECIPITATION TO ALONG THE FRONTAL BOUNDARY ACROSS NORTHERN UTAH.

THE FORECAST WAS UPDATED EARLIER TO ADJUST EARLY EVENING WINDS AND
SKY COVER. HAVE NOW MADE ADDITIONAL UPDATES TO MANY AREAS TO REFLECT
DECREASING TREND IN POP AND SKY AS WELL AS TO TWEAK WINDS AND
TEMPERATURES FOR THE REST OF THE NIGHT.

&&

.AVIATION...A CLEARING TREND CAN BE EXPECTED AT THE SLC TERMINAL
THROUGH LATE TONIGHT. MID AND HIGH CLOUDS WILL BEGIN TO INCREASE
OVER THE AREA AGAIN AFTER 09Z. WINDS WILL PREDOMINANTLY REMAIN OUT
OF THE SOUTHEAST FOR THE REMAINDER OF THE NIGHT...ALTHOUGH LIGHT AND
VARIABLE OR LIGHT NORTH WINDS MAY OCCUR AT TIMES THROUGH 06Z.

&&

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