AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
951 AM MDT TUE APR 15 2014

.SYNOPSIS...A COLD FRONT WILL CROSS NORTHERN UTAH THIS
AFTERNOON...THEN CONTINUE SOUTH THROUGH THE REMAINDER OF THE
STATE OVERNIGHT. A PAIR OF WEAK WEATHER SYSTEMS WILL FOLLOW FOR
WEDNESDAY AND FRIDAY NIGHT/SATURDAY.


&&

.DISCUSSION...THE RIDGE OVER THE FORECAST AREA HAS FLATTENED THIS
MORNING IN RESPONSE TO AN APPROACHING TROUGH. THIS SYSTEM WILL
GRAZE NORTHERN UTAH TODAY AND TONIGHT...BRINGING A MOSTLY DRY
FRONT INTO THE STATE. IT WILL MOVE INTO NORTHERN UTAH THIS
AFTERNOON BEFORE CONTINUING SOUTHWARD OVERNIGHT. MAXES TODAY ARE
EXPECTED TO BE IN EXCESS OF 5F ABOVE SEASONAL NORMS BUT BY
TOMORROW THEY SHOULD BE ABOUT 10F COOLER THAN TODAY...OR ABOUT 5F
BELOW CLIMO.

THE SYSTEM MAY BRING A FEW SHOWERS TO THE NORTHERN MOUNTAINS
TODAY BUT ANYTHING SHOULD BE GENERALLY LIGHT. A BIGGER CONCERN ARE
WINDS AHEAD AND PARTICULARLY BEHIND THE FRONT. MODELS INDICATE 700
MB FLOW UP TO 35 KTS...HOWEVER...AND THE PRESSURE GRADIENT IS NOT
OVERLY FAVORABLE SO DO NOT THINK ANY WIND HEADLINES ARE WARRANTED.

A SECOND WAVE IS PROGGED TO CROSS THE FORECAST AREA TOMORROW. THE
WAVE IS A BIT MORE OF A DIRECT HIT AND HAS SOME JET SUPPORT BUT IS
WEAK OVERALL. CURRENT THINKING IS THAT ANYTHING THAT DEVELOPS WILL
BE SCATTERED AT BEST. BEHIND THAT SYSTEM...HIGH PRESSURE IS
EXPECTED TO REDEVELOP FOR THURSDAY AND FRIDAY BEFORE ANOTHER
SYSTEM MOVES THROUGH FRIDAY NIGHT AND SATURDAY.

NO UPDATES EXPECTED TO THE FORECAST THIS MORNING.

&&

.AVIATION...WINDS AT THE SLC TERMINAL WILL INCREASE FROM THE SOUTH
THROUGH THE MORNING AHEAD OF AN APPROACHING COLD FRONT. WINDS WILL
SHIFT TO THE NORTHWEST BETWEEN 20Z AND 22Z...BECOMING MORE NORTHERLY
BETWEEN 2Z AND 4Z. VFR CONDITIONS WILL PREVAIL WITH CIGS ABOVE
6000FT.

&&

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