NORTHERN GREAT BASIN. 130KT JET STREAK NOTED WITHIN THE BASE OF THIS
TROUGH ALONG WITH TIGHT 700MB BAROCLINIC ZONE LOCATED ACROSS
NORTHERN NV. ASSOCIATED SURFACE FRONT IS LOCATED FROM NEAR JEROME ID
BACK THROUGH BATTLE MOUNTAIN NV. IR IMAGERY DEPICTS REGION OF STRONG
UPPER LEVEL DIFFLUENCE ALONG THIS BOUNDARY WITHIN EXIT REGION OF
JET STREAK ALOFT...WHICH IS SUPPORTING CLUSTER OF THUNDERSTORMS NEAR
WILDHORSE RESERVOIR NV. AHEAD OF THIS FRONT...700-500MB COLD
ADVECTION HAS SPREAD EAST ACROSS NORTHERN UT...WITH 88-D IMAGERY
BEGINNING TO DETECT LIGHT RETURNS ACROSS FAR NORTHERN UT. EXPECT

FLOORS BY MIDNIGHT. AS 700MB COLD POOL SPREADS ACROSS NORTHERN UT
700MB-LAKE TEMP DIFFERENTIAL APPROACHES 16C LATE TONIGHT...WHICH
WILL BE MARGINALLY SUFFICIENT TO SUPPORT DEVELOPMENT OF LAKE-INDUCED

HOURS. STRONG DRYING NOTED IN WV IMAGERY ALONG WITH TIGHT BAROCLINIC
STRUCTURE OF APPROACHING SYSTEM SUGGESTS WIND GUSTS WELL IN EXCESS

OPTED TO UPGRADE SNOW/BLOWING SNOW ADVISORY TO A WINTER STORM
WARNING FOR SOUTHERN WASATCH FRONT FOR THIS EVENING THROUGH SUNDAY
MORNING.

FINALLY...HAVE ISSUED A WIND ADVISORY FOR UTAHS DIXIE REGION FOR
LATE TONIGHT THROUGH SUNDAY MORNING. EXPECT STRONG GUSTY WINDS TO
ACCOMPANY FRONT LATE TONIGHT. 700MB COLD ADVECTION ALONG WITH

FORECAST AREA. MID LEVEL RIDGE EXPECTED TO AMPLIFY ACROSS THE REGION
FOR THE UPCOMING WEEK. HAVE LEANED TOWARDS EC/GEM SOLUTION WHICH
