AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
305 AM MDT MON JUL 31 2007

.SYNOPSIS...ABUNDANT MOISTURE OVER SOUTHWEST UTAH WILL SPREAD
NORTHWARD ACROSS THE REGION TODAY. THIS MOISTURE WILL REMAIN IN
PLACE THROUGH THE END OF THE WEEK...RESULTING IN NUMEROUS SHOWERS
AND THUNDERSTORMS EACH DAY.

&&

.DISCUSSION...EARLY MORNING WATER VAPOR IMAGERY AND OBJECTIVE
ANALYSIS INDICATES MID LEVEL RIDGE AXIS HAS SHIFTED INTO EASTERN
UTAH. THIS IS ALLOWING ABUNDANT MOISTURE...WHICH HAS RESIDED ACROSS
THE DESERT SOUTHWEST OVER THE PAST FEW DAYS...TO BEGIN SURGING
NORTHWARD. GOES PW IMAGERY SUGGESTS AXIS OF 1 INCH PLUS PW VALUES
HAS SPREAD NORTHWARD ACROSS NORTHERN UT...AND THIS IS SUPPORTED BY
LOCAL IPW SENSOR LOCATED AT THE SLC FORECAST OFFICE. AREA OF WEAK
SHOWERS CURRENTLY ACROSS NORTHWEST UT LIKELY ASSOCIATED WITH
ISENTROPIC LIFT ASSOCIATED WITH LEADING EDGE OF MOISTURE SURGE.
MEANWHILE A LARGER AREA OF SHOWERS AND ISOLATED THUNDERSTORMS
CONTINUES ACROSS NORTHERN AZ/SOUTHERN NV AND FAR SOUTHERN UT. THIS
APPEARS TO BE DRIVEN BY WEAK CONVECTIVELY INDUCED VORT MAX ROTATING
AROUND PERIPHERY OF MID LEVEL RIDGE.

WITH ABUNDANT MOISTURE AND GENERALLY WEAK DEEP LAYER FLOW IN PLACE
CERTAINLY THE BIGGEST CONCERN FOR TODAY IS POTENTIAL FOR FLASH
FLOODING ACROSS SOUTHERN UT. HOWEVER SEVERAL LIMITING FACTORS
CONTINUE TO RAISE CONSIDERABLE UNCERTAINTY WITH RESPECT TO
CONVECTIVE INITIATION AND SUBSEQUENT COVERAGE ACROSS SOUTHERN UT
THIS AFTERNOON. ABUNDANT CLOUD COVER IN ASSOCIATION WITH ONGOING
CONVECTION CONTINUES TO SPREAD INTO SOUTHERN UT AT THIS HOUR. THIS
CLOUD COVER WOULD GREATLY REDUCE SURFACE HEATING/DESTABILIZATION
THIS AFTERNOON...AND THUS AT LEAST DELAY INITIATION...IF NOT GREATLY
LIMIT AREAL COVERAGE. IN ADDITION...ASSUMING WEAK VORT MAX ACROSS
NORTHERN AZ IS ABLE TO SUSTAIN ITSELF...WAKE SUBSIDENCE MAY ALSO
LIMIT INITIATION AND COVERAGE THIS AFTERNOON. HAVE OPTED TO MAINTAIN
A HIGH FLASH FLOOD POTENTIAL FOR TODAY ACROSS SOUTHWEST AND SOUTH
CENTRAL UT TO HEIGHTEN AWARENESS...HOWEVER WILL HOLD OFF ON ISSUANCE
OF WATCH UNTIL SITUATION BECOMES A BIT MORE CERTAIN.

MEANWHILE FURTHER NORTH INCREASED MOISTURE SHOULD ALLOW FOR
SCATTERED CONVECTION ACROSS THE REMAINDER OF THE FORECAST AREA THIS
AFTERNOON AND EVENING. ANY CONVECTION WHICH DOES FORM WOULD
CERTAINLY HAVE THE POTENTIAL TO PRODUCE LOCALLY HEAVY RAINFALL.

LITTLE CHANGE IN THE OVERALL PATTERN IS EXPECTED THROUGH THE
REMAINDER OF THE WEEK...AS A VERY MOIST AIRMASS WILL RESIDE ACROSS
THE REGION. THIS SHOULD ALLOW FOR FAIRLY WIDESPREAD SHOWERS AND
THUNDERSTORMS EACH DAY...WITH THE POTENTIAL FOR LOCALLY HEAVY
RAINFALL AND POSSIBLE FLASH FLOODING IN FAVORED AREAS. PRECIPITATION
AND CLOUD COVER SHOULD ALSO ALLOW FOR A SLIGHT COOLING TREND THROUGH
THE PERIOD.

UNCERTAINLY INCREASES BY THE UPCOMING WEEKEND...AS MODEL SOLUTIONS
DIVERGE IN HANDLING OF SHORTWAVE TROUGH FORECAST TO DIG INTO THE
PACIFIC NORTHWEST. ECMWF HAS SHOWN BETTER RUN TO RUN CONSISTENCY
MOVING THIS TROUGH EASTWARD ACROSS THE NORTHERN ROCKIES...WHICH
WOULD LIKELY PUSH MOISTURE AXIS OUT OF NORTHERN UT. HAVE TRENDED IN
THIS DIRECTION...ALTHOUGH WILL MAINTAIN LOW POPS ACROSS NORTHERN UT
THROUGH SUNDAY.

&&

.AVIATION...SOUTHEASTERLY WINDS WILL PREVAIL OVERNIGHT AND THIS
MORNING AT THE SLC TERMINAL. THE WIND SHIFT TO THE NORTHWESTERLY
LAKE BREEZE IS EXPECTED AT AROUND 19Z...CLOSE TO THE USUAL TIME.
OUTFLOW FROM NEARBY THUNDERSTORMS WILL LIKELY PRODUCE PERIODS OF
GUSTY WINDS WITH ERRATIC DIRECTIONS...PRIMARILY LATE THIS AFTERNOON
AND EARLY THIS EVENING. THERE IS A 30 PERCENT CHANCE THAT A
THUNDERSTORM WILL DIRECTLY IMPACT THE TERMINAL LATER TODAY.

&&

.FIRE WEATHER...MOISTURE WILL CONTINUE TO INCREASE AND SPREAD
NORTHWARD...ALLOWING FOR INCREASED COVERAGE OF SHOWERS AND
THUNDERSTORMS THIS AFTERNOON. THE STORMS SHOULD BE WET...BUT A FEW
DRY LIGHTNING STRIKES CANNOT BE RULED OUT OVER NORTHERN UTAH AWAY
FROM THUNDERSTORM CORES. ALSO...SOME STORMS MAY PRODUCE PERIODS OF
GUSTY WINDS. THUNDERSTORMS WILL CONTINUE THROUGH THE REST OF THE
WEEK AS AMPLE MOISTURE WILL REMAIN IN PLACE.

&&

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