AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
916 PM MDT MON OCT 12 2009

.SYNOPSIS...A SERIES OF MOIST PACIFIC WEATHER DISTURBANCES WILL
RACE THROUGH THE AREA TONIGHT THROUGH WEDNESDAY. HIGH PRESSURE
WILL RETURN AND STRENGTHEN ACROSS THE REGION FOR THE REMAINDER OF
THE WEEK.

&&

.DISCUSSION...THE TROF IN THE ERN PAC CONTINUES TO DEEPEN THIS EVE
AS IT PHASES WITH THE LOW SLIDING WEST FROM SWRN CANADA. A LEADING
SHORT WAVE IS EJECTING OUT OF THIS TROF AND IS ENTERING THE GREAT
BASIN THIS EVE. THIS FEATURE WILL BE MINORING OUT AS IT LIFTS
NEWD THRU UT AND ERN NV TONIGHT BUT IT DOES SPREAD SUFFICIENT
MOISTURE AND LIFT INTO THE AREA TO GENERATE SCATTERED SHOWERS AS
IT PASSES.

SHOWERS HAVE ALREADY DEVELOPED ACROSS SWRN UT AND EXPECT THESE TO
KEEP FORMING AND SPREADING NORTHEASTWARD UNTIL THE TROF AXIS
PASSES LATER TONIGHT. THE BEST COVERAGE AS DEPICTED BY GUIDANCE
SHOULD BE OVER THE NRN MTNS AFTER MIDNIGHT AND THIS IS REASONABLE.

EXPECT A LULL IN THE SHOWER ACTIVITY FROM ABOUT MID MORNING
THROUGH LATE AFTERNOON TOMORROW AS THIS WAVE EXITS THE AREA.

THE NEXT STRONGER TROF EJECTS INLAND TUE NIGHT THRU MIDDAY WED.
HOWEVER...THE PHASED PARENT LOW REMAINS OUT IN THE ERN PAC SO THIS
WAVE WILL ALSO BE MINORING OUT AS IT MOVES INLAND BUT IT WILL
HAVE FAIR JET SUPPORT AND ABUNDANT MOISTURE AND SHOULD BRING
WIDESPREAD PRECIP ANYWAY.

WITH THE PARENT LOW STAYING OUT AT 140W...RIDGING WILL BUILD INTO
THE GREAT BASIN RAPIDLY BEHIND THE EJECTING WAVE AND THE
INCREASING STABILITY WILL SHUT DOWN THE PRECIP FAIRLY QUICKLY
LATE WED AND WED NIGHT IN SPITE OF THE LINGERING MOISTURE.

HAVE UPDATED FORECASTS EARLIER TO INCREASE CLOUD COVER TONIGHT
AND THE OVERNIGHT DISTRIBUTION OF POPS...AND TO CHANGE PRECIP
WORDING FROM UNCERTAINTY TO COVERAGE. NO FURTHER UPDATES PLANNED AT
THIS TIME.

&&

.AVIATION...SOUTH WINDS WILL CONTINUE AT THE SLC TERMINAL THROUGH
THE OVERNIGHT HOURS...AND COULD BE GUSTY AT TIMES IN THE VICINITY
OF SHOWERS AFTER ABOUT 06Z. CEILINGS WILL LOWER THROUGH THE
NIGHT...WITH A 60 PERCENT CHANCE OF CIGS BELOW 7000FT AGL BETWEEN
06Z AND 14Z. THERE IS ALSO A 10 PERCENT CHANCE OF MVFR CIGS IN
RAIN SHOWERS DURING THIS SAME TIME.

&&

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