AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1113 AM MDT SUN OCT 27 2013

.SYNOPSIS...HIGH PRESSURE OVER THE AREA WILL SHIFT EAST TODAY AHEAD
OF A STORM SYSTEM DROPPING SOUTH INTO THE WESTERN GREAT BASIN. THIS
SYSTEM WILL SLOWLY CROSS THE GREAT BASIN MONDAY THROUGH WEDNESDAY.
HIGH PRESSURE WILL RETURN FOR THE END OF THE WEEK.

&&

.DISCUSSION...A VIGOROUS SHORTWAVE TROUGH/CLOSED LOW CURRENTLY
DROPPING SOUTH THROUGH THE PACIFIC NORTHWEST WILL CONTINUE TO
DEEPEN AS IT CONTINUES ON THIS TRAJECTORY THROUGH THIS
EVENING...BEFORE EVENTUALLY STALLING ACROSS THE WESTERN GREAT
BASIN OVERNIGHT. MID AND HIGH LEVEL CLOUD COVER IS EXPECTED TO
INCREASE CONSIDERABLY THIS AFTERNOON AS LARGE SCALE ASCENT
STRENGTHENS IN RESPONSE TO THIS APPROACHING TROUGH.
ADDITIONALLY...INCREASING PRESSURE FALLS IN RESPONSE TO DEEPENING
SURFACE LOW SHOULD ALLOW SOUTHERLY WINDS TO INCREASE DURING THE
AFTERNOON AND EVENING HOURS...AND ATTENDANT MIXING SHOULD ALLOW
TEMPERATURES TO REACH THE LOW 70S ALONG MUCH OF THE WASATCH FRONT.

AS THIS UPPER LOW SLOWLY SHIFTS EAST DURING THE DAY MONDAY THE
ASSOCIATED SURFACE LOW IS FORECAST TO ROTATE NORTHEASTWARD ACROSS
NORTHEAST NV DURING THE DAY. THIS GRADIENT WILL RESULT IN STRONG
WINDS ACROSS MOST CENTRAL AND SOUTHERN VALLEYS MONDAY MORNING INTO
THE AFTERNOON...AND WILL LIKELY NEED TO HOIST A WIND ADVISORY WITH
THE AFTERNOON PACKAGE.

A VORTICITY LOBE ROTATING AROUND THIS LOW IS FORECAST TO LIFT
NORTHEAST ACROSS THE FORECAST AREA MONDAY AFTERNOON AND
EVENING...USHERING MUCH COOLER AIR INTO THE FORECAST AREA.
PRECIPITATION WILL ACCOMPANY THIS FEATURE AS IT LIFTS ACROSS THE
FORECAST AREA...WITH SNOW LEVELS FALLING TO NEAR 6000 FEET BY
MID EVENING. AM A BIT CONCERNED THE DURATION OF PRECIPITATION
ACROSS THE NORTH MAY BE SOMEWHAT SHORT GIVEN THE RAPID PROGRESSION
OF THIS WAVE...BUT MAY LINGER ACROSS THE CENTRAL AND SOUTHERN
MOUNTAINS THROUGH THE EVENING AND OVERNIGHT HOURS.

THE UPPER LOW WILL GRADUALLY PROGRESS EAST ACROSS THE FORECAST
AREA WITH PRECIPITATION BECOMING MORE CONVECTIVE IN NATURE. 700MB
TEMPS AT OR BELOW -6C COMBINED WITH THE SHOWERY NATURE OF
PRECIPITATION WILL LIKELY ALLOW SNOW TO MIX IN DOWN TO THE VALLEY
FLOORS.

THE 12Z GFS HAS CONTINUED ITS RECENT TREND OF SWINGING ANOTHER
WAVE SOUTH INTO NORTHERN UT TUESDAY NIGHT INTO WEDNESDAY MORNING
BRINGING ANOTHER ROUND OF STRATIFORM PRECIPITATION...WITH SNOW
LEVELS LIKELY FALLING NEAR THE VALLEY FLOORS WEDNESDAY MORNING.
THE 00Z EC DOES NOT YET SUPPORT THIS IDEA NOR DOES THE 12Z NAM.

&&

.AVIATION...THE SLC TERMINAL WILL SEE VFR CONDITIONS THROUGHOUT THE
DAY WITH INCREASING HIGH CLOUDS. SOUTHERLY WINDS ARE EXPECTED
THROUGH THE DAYTIME HOURS...BECOMING GUSTY THIS AFTERNOON. THERE IS
A 20 PERCENT CHANCE OF A LATE WIND SHIFT TO THE NORTHWEST...BETWEEN
21Z AND 23Z.

&&

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