NWS Salt Lake City, UT wrote its last area forecast discussion before the first event at Nov 14, 4:35 PM MST, 25 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE SALT LAKE CITY UT 435 PM MST SUN NOV 14 2010 UPDATED AVIATION SECTION .SYNOPSIS...A COOL AND MOIST NORTHWESTERLY FLOW ALOFT WILL REMAIN OVER THE GREAT BASIN THROUGH TUESDAY. A SERIES OF WEATHER DISTURBANCES EMBEDDED IN THIS NORTHWEST FLOW WILL CROSS THE REGION THROUGH THAT TIME. HIGH PRESSURE ALOFT WILL DEVELOP OVER THE REGION ON WEDNESDAY. && .DISCUSSION...SHALLOW MOIST NORTHWEST FLOW WILL CONTINUE ACROSS THE REGION TONIGHT WITH THE FIRST OF SEVERAL EMBEDDED WEAK DISTURBANCES MOVING THROUGH THIS EVENING. THE 12Z NAM FORECAST SOUNDING PROFILE INDICATED THAT THE PRECIPITATION WOULD REMAIN IN THE FORM OF FREEZING DRIZZLE OR MIST THROUGH MID EVENING BEFORE COOLING ENOUGH AT CLOUD TOPS TO CREATE ICE NUCLEATION AND THEREFORE CHANGE PRECIP TO SNOW. HOWEVER...LATEST 18Z NAM SHOWS THAT THIS MAY NOT OCCUR UNTIL AFTER MIDNIGHT. THEREFORE SNOW ACCUMULATIONS HAVE BEEN KEPT TO LOWER AMOUNTS DUE TO MORE PRECIP IN THE FORM OF LIQUID THEN SNOW. NORTHERN VALLEYS SHOULD SEE TEMPERATURES REMAINING IN THE MID TO UPPER 30S TONIGHT SO THE THREAT OF SNOW IS UNLIKELY...AND NO ACCUMULATING SNOW IS EXPECTED BELOW 5500 FT. ANOTHER WEAK DISTURBANCE MOVES THROUGH MONDAY IN ASSOCIATION WITH THE JET MOVE MOVING OVERHEAD SO FIGURE THERE SHOULD SOME ENHANCED LIFT TO BRING ANOTHER THREAT OF PRECIPITATION...MAINLY NORTHERN MOUNTAINS. THE NAM AND GFS SHOW ANOTHER WAVE TO MOVE THROUGH AT MID LEVELS BETWEEN 06Z TUESDAY AND 18Z TUESDAY. THIS IS THE LAST OF THE DISTURBANCES TO MOVE OVER THE RIDGE AND WILL LIKELY BE A LITTLE STRONGER...ESPECIALLY OVER NORTHERN UTAH. THIS FEATURE SHOWS SIGNS OF HAVING BOTH SPEED AND CURVATURE CONVERGENCE AT 700 MB ALONG WITH A THERMAL GRADIENT. TEMPERATURES WILL REMAIN MILD ENOUGH BELOW ABOUT 6000 FT FOR RAIN WHILE ABOVE 6000 FT SNOW IS EXPECTED. THE RIDGE OF HIGH PRESSURE WILL THEN BUILD OVER THE ENTIRE REGION FOR WEDNESDAY INTO FRIDAY. A LARGE TROUGH MOVES INTO THE WEST COAST AND NORTHERN GREAT BASIN THIS WEEKEND. THINGS SHOULD GET QUITE INTERESTING SATURDAY AFTERNOON AND BEYOND AS THE SURFACE COLD FRONT APPEARS TO MOVE INTO CENTRAL UTAH WHILE A STRONG SOUTHWEST JET ALOFT MOVES OVERHEAD SETTING UP THE POSSIBILITY OF CONDITIONAL SLANTWISE INSTABILITY. TEMPERATURES WILL BE COLD ENOUGH FOR VALLEY SNOW FROM CEDAR CITY NORTHWARD OVER THE WESTERN VALLEYS. BOTH THE EC AND NAM ARE IN PRETTY CLOSE AGREEMENT ON THIS. THE UPPER LEVEL TROUGH DOES NOT MOVE ACROSS UTAH UNTIL MONDAY SO THERE COULD BE ABOUT 36 TO 48 HOURS OF THIS MOIST SOUTHWEST FLOW OVER A COLD LOW LEVEL NORTHERLY FLOW. && .AVIATION...MVFR CEILINGS ARE EXPECTED TO REMAIN AT KSLC THROUGH AT LEAST MIDDAY MONDAY. THERE IS A 30 PERCENT CHANCE OF CEILINGS BRIEFLY LIFTING ABOVE 3000FT FROM TIME TO TIME. SOUTHEAST WINDS ARE EXPECTED TO CONTINUE THROUGH THE NIGHT AND MONDAY MORNING. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...NONE.
