AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
955 AM MST MON FEB 12 2007

.SYNOPSIS...HIGH PRESSURE WILL BRIEFLY BUILD ACROSS THE REGION
TODAY...BEFORE A STORM SYSTEM IMPACTS PRIMARILY CENTRAL AND SOUTHERN
UTAH TONIGHT THROUGH TUESDAY.

&&

.DISCUSSION...QUICK LOOK AT 12Z GFS AND NAM INDICATE DISORGANIZED
TROUGH ALONG CA COAST THIS MORNING WILL MOVE INLAND AND GENERATE A
CONVERGENCE ZONE ACROSS CENTRAL NV EXTENDING EAST INTO CENTRAL UT
TONIGHT AND TUESDAY. PRECIP IN THIS ZONE LIKELY TO BEGIN OVERNIGHT.
SEEMS LIKELY CENTRAL UT MOUNTAINS WILL SEE ADVISORY AMOUNTS OF SNOW
TONIGHT AND TUESDAY. LESS CERTAIN ABOUT NORTHWARD EXTENT OF
PRECIP...MAY BE UTAH COUNTY AND PERHAPS SL COUNTY...BUT PROBABLY NOT
TOO MUCH FURTHER NORTH. SNOW LEVELS ACROSS THE CENTRAL VALLEYS
SHOULD BE NEAR 4500 FEET.

SOME CONCERN THAT DETAILS OF THE OFFSHORE TROUGH ARE NOT WELL
HANDLED IN THIS MORNINGS 12Z ANALYSIS. WV SAT IMAGERY DOES NOT MATCH
UP WITH MODEL VORTICITY FEATURES AS WELL AS ONE WOULD LIKE. THIS
MAKES MODEL DETAILS A BIT HARD TO TAKE AT FACE VALUE...AND NAM HAS
EXTREME PRECIP BOMB NEAR ELY BETWEEN 0-6Z IN THE MIDDLE OF THE
AFOREMENTIONED CONVERGENCE ZONE AND THIS HIGH PRECIP AREA THEN
SPREADS EASTWARD INTO UT...IDEA MIGHT BE OK...BUT 1.74 INCH BULLSEYE
IN 6 HOURS LOOKS SPURRIOUS.

NO CHANGES TO FORECAST AT THIS TIME.

.AVIATION...SEE SLCTAFSLC.
