AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
234 AM MDT MON SEP 1 2014

.SYNOPSIS...HIGH PRESSURE WILL BUILD OVER THE REGION THROUGH
MIDWEEK ALLOWING FOR A WARMING TREND. A MILD SOUTHWESTERLY FLOW
WILL FOLLOW FOR THE LATTER HALF OF THE WEEK INTO NEXT WEEKEND.

&&

.DISCUSSION...A WEST-NORTHWESTERLY FLOW ALOFT PREVAILS ACROSS THE
INTERMOUNTAIN WEST EARLY THIS MORNING. A SURFACE COLD FRONT WHICH
PUSHED THROUGH NORTHERN AND CENTRAL UT DURING THE DAY SUNDAY
REMAINS STALLED ACROSS SOUTHERN UT...AND WILL EFFECTIVELY DISSIPATE
OVER THE NEXT DAY OR SO AS THE AIRMASS IN THE WAKE OF THIS FRONT
GRADUALLY MODIFIES. AS SUCH HAVE MAINTAINED A WARMING TREND ACROSS
NORTHERN AND CENTRAL UT THROUGH TUESDAY WITH LITTLE CHANGE IN DAY
TO DAY TEMPERATURES EXPECTED ACROSS THE SOUTH.

THE FLOW ALOFT IS FORECAST TO BACK TO SOUTHWESTERLY DURING THE
LATTER HALF OF THE WEEK...AS AN UPPER TROUGH DEVELOPS ALONG THE
PACIFIC COAST. MID AND HIGH LEVEL MOISTURE EMBEDDED WITHIN THIS
FLOW IS EXPECTED TO WORK ACROSS THE AREA THURSDAY INTO
FRIDAY...AND AS SUCH HAVE MAINTAINED SLIGHT CHANCE POPS MAINLY
ACROSS THE HIGHER TERRAIN. THE GFS CONTINUES TO SUGGEST TROPICAL
MOISTURE EVENTUALLY WORKS ITS WAY INTO THE DESERT SOUTHWEST OVER
THE WEEKEND...AND ALTHOUGH THIS WOULD BE AN INTERESTING
SCENARIO...THE ECMWF HAS NOT CLIMBED ON BOARD WITH THIS IDEA. AS
SUCH HAVE LEFT ONLY TOKEN SLIGHT CHANCE POPS IN THE FORECAST FOR
NEXT WEEKEND.

&&

.AVIATION...SOUTHEAST WINDS ARE EXPECTED TO SWITCH TO THE
NORTHWEST BETWEEN 17Z AND 19Z AT THE SLC TERMINAL. OTHERWISE EXPECT
VFR CONDITIONS UNDER MOSTLY CLEAR SKIES.

&&

.FIRE WEATHER...COOLER WITH A DRY AND STABLE AIRMASS TODAY...THUS
EXPECT BELOW NORMAL TEMPERATURES ACROSS MUCH OF THE STATE. A
WARMING TREND WILL BEGIN TUESDAY AS HIGH PRESSURE ALOFT REBOUNDS.
TEMPERATURES ARE EXPECTED TO RETURN TO NEAR OR SLIGHTLY ABOVE
SEASONAL NORMS MIDWEEK. INCREASING SOUTHERLY WINDS ACROSS NORTHERN
AND WESTERN UTAH ARE ANTICIPATED AHEAD OF THE NEXT PACIFIC STORM
SYSTEM. THIS STORM SYSTEM COULD DRAW MOISTURE NORTH INTO SOUTHERN
UTAH FOR WEDNESDAY INTO THURSDAY. IF THIS OCCURS...ISOLATED
CONVECTION WILL FORM OVER THE HIGHER TERRAIN BY LATE WEDNESDAY
AFTERNOON...WITH A SLIGHTLY BETTER CHANCE OF ADDITIONAL SHOWERS
AND THUNDERSTORMS ON THURSDAY.
