AREA WITH SOUTHWEST FLOW ALOFT INCREASING AHEAD OF THE APPROACHING
EASTERN NEVADA DISTURBANCE. OLD UPPER LOW SPINNING OVER NEW MEXICO
CREATES A DEFORMATION AXIS NOW OVER EASTERN UTAH AND KANE COUNTY.

810 PM DISCUSSION...
UPPER TROUGH AND ASSOCIATED LOW LEVEL BOUNDARY WIND
SHIFT CONTINUES TO PRESS ACROSS CENTRAL UTAH THIS EVENING. THIS
BOUNDARY PRODUCED SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS IN
NORTHEAST UTAH THIS MORNING AND TIMED WITH THE HEATING OF THE DAY
BROUGHT SCATTERED THUNDERSTORMS TO UTAH THIS AFTERNOON FROM PROVO TO
EVANSTON SOUTHWARD. NORTHWEST OF THIS LINE THE AIR MASS STABILIZED
THROUGH THE AFTERNOON DUE TO NVA DRYING AND SUBSIDENCE IN THE WAKE
OF THE UPPER TROUGH. STRONGEST STORMS ASSOCIATED WITH TERRAIN AND

ACTIVITY PERSISTING IN THE SOUTHERN PART OF UTAH. A SEPARATE SHORT
WAVE TROUGH IS OVER EASTERN NEVADA...THIS IS PROGGED TO LIFT
NORTHEAST ACROSS WESTERN UTAH LATER TONIGHT AND BACK THE MEAN FLOW
TO SOUTHWEST. THIS WILL GENERATE SCATTERED CONVECTION OVER WESTERN
UTAH THIS EVENING...WITH PRECIPITABLE WATER PLUME RETURNING BACK TO
THE IDAHO BORDER AND GSL REGION LATE TONIGHT AND MONDAY MORNING.

UPDATED EARLIER TO REMOVE WEATHER IN NORTHWEST UTAH EXCEPT NEAR THE
WYOMING AND NEVADA BORDERS. LEFT LOW CHANCES AFTER MIDNIGHT FOR THE

TONIGHT. CLOUDS AND SCATTERED PRECIPITATION WILL ADVECT ACROSS
NORTHERN UTAH WITH THIS NEXT WAVE OVERNIGHT AND MONDAY MORNING.

BROAD PACIFIC TROUGH MOVING INTO THE NORTHWEST COAST WILL DROP A
COLD FRONT ACROSS NORTHERN UTAH MONDAY NIGHT. AHEAD OF THIS...SOUTH
FLOW ALOFT WILL INCREASE ON MONDAY AND SPREAD MOISTURE BACK TO THE
IDAHO BORDER. SIMILAR AIR MASS TEMPERATURES ON MONDAY AND HEATING OF
THE DAY WILL REDEVELOP CONVECTION OVER THE SPINE OF UTAH...BUT
FASTER MORNING STORMS...ESPECIALLY NORTH AREAS. THE MORNING SHORT
WAVE TROUGH LIFTS ACROSS CENTRAL UTAH AND INTO FAR NORTHERN UTAH BY
MIDDAY. OLD LOW LEVEL BOUNDARY IN THE SOUTH PROG TO SLOWLY LIFT
NORTH INTO SOUTH CENTRAL UTAH PER 00Z NAM. MODERATE UPPER TROUGH
