AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
934 AM MDT MON APR 22 2013

.SYNOPSIS...A COLD FRONT WILL MOVE SOUTH ACROSS UTAH TODAY WITH A
COLD AIRMASS REMAINING IN PLACE THROUGH WEDNESDAY. A SLOW WARMING
TREND IN NORTHWEST FLOW WILL FOLLOW FOR THURSDAY THROUGH SATURDAY.

&&

.DISCUSSION...A FEW SHOWERS ARE ONGOING ACROSS PORTIONS OF
NORTHEASTERN UTAH THIS MORNING. THESE SHOWERS SHOULD CONTINUE AND
EVEN INCREASE IN COVERAGE THIS AFTERNOON AS THE COLD POOL
ASSOCIATED WITH A RELATIVELY STRONG TROUGH MOVING ACROSS THE
CENTRAL PORTION OF THE COUNTRY STARTS TO PULL AWAY FROM THE
REGION. CURRENT POPS HANDLE THIS WELL...SO NO UPDATES ARE
ANTICIPATED. EXPECT ANY ACCUMULATIONS TO REMAIN BELOW 1 INCH IN
THE MOUNTAINS.

TWO MAIN ISSUES ARE ONGOING IN THE SHORT TERM PORTION OF THE
FORECAST. FIRST...WILL BE THE POTENTIAL FOR A GAP WIND EVENT
ACROSS WASHINGTON COUNTY THIS EVENING INTO TUESDAY MORNING. A DRY
COLD FRONT WILL PUSH ACROSS THE STATE TODAY. AS THIS COLD FRONT
APPROACHES WASHINGTON COUNTY...IT WILL HELP TO INCREASE THE
PRESSURE GRADIENT ACROSS SOUTHWESTERN UTAH. LIMITING FACTORS FOR
THIS EVENT WILL BE MIDLEVEL WESTERLY FLOW AND SOMEWHAT WEAK COLD
AIR ADVECTION. WILL WAIT FOR THE REMAINDER OF THE 12Z MODELS
BEFORE MAKING ANY DECISIONS...BUT INITIAL REVIEW OF THE 12Z NAM
AND LOCAL STUDY INFORMATION LEAN TOWARD AN ADVISORY EVENT FOR THIS
AREA. WILL LIKELY ISSUE A WIND ADVISORY WITH THE AFTERNOON
PACKAGE.

THE SECOND MAIN ISSUE WILL BE THE POTENTIAL FOR HARD FREEZE
CONDITIONS ACROSS NORTHERN UTAH TONIGHT. CURRENT FORECAST CALLS
FOR TEMPERATURES NEAR TO BELOW 28F OVERNIGHT ACROSS AREAS NORTH OF
OGDEN...THE CACHE VALLEY AND OUTLYING AREAS OF THE SALT LAKE AND
UTAH VALLEYS. WILL LIKELY NEED TO ISSUE A HARD FREEZE WARNING FOR
THESE LOCATIONS WITH THE AFTERNOON PACKAGE...BARRING ANY MODEL
CHANGES. ANY SENSITIVE VEGETATION IN THESE AREAS SHOULD BE COVERED
OR BROUGHT INDOORS IF POSSIBLE TONIGHT. APRIL 23RD IS THE AVERAGE
DATE OF LAST FREEZE DURING THE SPRING FOR SALT LAKE CITY...SO
THESE COLD TEMPERATURES ARENT FAR OUTSIDE THE RANGE OF NORMAL.

NORTHWEST FLOW REMAINS IN PLACE ACROSS THE AREA THROUGH MIDWEEK.
THIS WILL KEEP TEMPERATURES BELOW NORMAL THROUGH AT LEAST
WEDNESDAY. MODEL TO MODEL AND RUN TO RUN CONSISTENCY FALL TO BELOW
NORMAL LEVELS BEYOND THIS PERIOD...WITH MODELS COMPLETELY OUT OF
PHASE BY THE END OF THE FORECAST. NEEDLESS TO SAY...CONFIDENCE IN
THE EXTENDED IS LOW.

THE REMAINDER OF THE FORECAST IS ON TRACK...SO NO UPDATES ARE
NEEDED AT THIS POINT.

&&

.AVIATION...NORTHWEST WINDS AT THE SLC TERMINAL WILL INCREASE
THROUGH MIDDAY THEN TEND TO HOLD STEADY OR GRADUALLY DECREASE
THROUGH THE AFTERNOON. THERE IS A 20 PERCENT CHANCE OF SHOWERS AT
THE SLC TERMINAL THROUGH ABOUT 20Z. CIGS SHOULD LIFT OVER 7K FT AGL
AFTER 22Z...BUT THERE IS A 30 PERCENT CHANCE THAT CIGS WILL NOT LIFT
ABOVE 7K FT AGL UNTIL AFTER 01Z.

&&

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