.SYNOPSIS...HIGH PRESSURE ACROSS THE REGION TONIGHT WILL YIELD TO A
WEAK COLD FRONT CROSSING NORTHERN UTAH WEDNESDAY. MONSOONAL MOISTURE
WILL RETURN TO THE REGION LATE IN THE WEEK.

&&

.DISCUSSION...WHAT FEW SHOWERS AND THUNDERSTORMS THAT DEVELOPED OVER
THE FORECAST AREA TODAY HAVE MOSTLY DISSIPATED WITH THE LOSS OF
DAYTIME HEATING. A POCKET OF MOISTURE REMAINS IN PLACE ACROSS
NORTHERN UTAH WHILE SOUTHERN UTAH IS ON THE DRIER SIDE.
HOWEVER...THE MOISTURE ACROSS THE NORTH AND ITS PROXIMITY TO AN
UPPER JET NOSING INTO FAR NORTHWEST UTAH LATER TONIGHT IN ADVANCE OF
AN UPSTREAM TROUGH MAKES THE FAR NORTHWEST CORNER STILL SUSCEPTIBLE
TO A FEW ADDITIONAL SHOWERS TONIGHT. OTHERWISE...MID AND HIGH CLOUDS
AHEAD OF SAID TROUGH HAVE INFILTRATED MUCH OF UTAH THIS EVENING.

THE TROUGH...WHICH IS CURRENTLY OVER NORTHERN CALIFORNIA...WILL
CROSS NORTHERN UTAH TOMORROW. THIS WILL BRING A COLD FRONT AND
PRECIPITATION TO NORTHERN UTAH WHILE SOUTHERN UTAH REMAINS DRY.

MADE MINOR UPDATES TO REDUCE POPS AND ADJUST SKY FOR THE REST OF THE
NIGHT.

&&

.AVIATION...WINDS AT THE SLC TERMINAL ARE EXPECTED TO REMAIN
SOUTHERLY THROUGH THE NIGHT...THEN INCREASE IN SPEED TOWARDS
SUNRISE. CLOUDS WILL INCREASE TONIGHT...BUT CEILINGS SHOULD REMAIN
WELL ABOVE 7000FT THROUGH AT LEAST 12Z WEDNESDAY.

&&

.FIRE WEATHER...A COLD FRONT WILL CROSS THE NORTHERN PORTIONS OF THE
DISTRICT DURING THE DAY WEDNESDAY. LOCAL GUSTY SOUTH WINDS WILL
DEVELOP THROUGH THE WESTERN VALLEYS AHEAD OF THIS FRONT WITH WINDS
SHIFTING TO NORTHWEST BEHIND IT. ISOLATED SHOWERS AND THUNDERSTORMS
WILL ALSO DEVELOP OVER THE NORTH ALONG THIS FRONT TOMORROW BUT
CENTRAL AND SOUTHERN UTAH WILL BE DRIER AND STORMS ARE NOT EXPECTED.
HIGH PRESSURE RETURNS BRIEFLY FOR THURSDAY ALTHOUGH MOISTURE WILL
START TO SPREAD INTO SOUTHWESTERN UTAH FROM THE SOUTH DURING THE
AFTERNOON. THIS WILL BRING AN INCREASING CHANCE OF SHOWERS AND
THUNDERSTORMS TO THE DISTRICT THURSDAY NIGHT THROUGH FRIDAY.
