AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1000 AM MDT SAT JUL 30 2005

.SYNOPSIS...HIGH PRESSURE ALOFT CENTERED OVER THE CENTRAL ROCKIES
WILL MAINTAIN A MOIST SOUTHERLY FLOW INTO UTAH THROUGH EARLY NEXT
WEEK.

&&

.DISCUSSION...HIGH PRESSURE OVER COLORADO WILL CONTINUE TO ALLOW
MOISTURE TO MOVE INTO THE AREA UNDER A SOUTH TO SOUTHWESTERLY FLOW.
MAIN MOISTURE AXIS ACROSS NORTHERN...WEST CENTRAL AND SOUTHWEST UTAH
AND SOUTHERN NEVADA. GOES-DERIVED PRECIPITABLE WATER 1 INCH OR
GREATER ALONG THIS AXIS WITH AROUND 0.75 TO 1 INCH ELSEWHERE ACROSS
THE CWA. DEWPOINTS CONTINUE TO RISE AREAWIDE...WITH READINGS IN THE
50S OVER THE WESTERN PORTIONS THIS MORNING AND AT LEAST 40 OVER THE
EAST.

QUITE A BIT OF CLOUD COVER REMAINS FROM ACTIVITY YESTERDAY EVENING
AND OVERNIGHT. CONVECTION SHOULD BE LIMITED UNTIL THESE CLOUDS
DECREASE. BY AFTERNOON...WOULD EXPECT ANOTHER ACTIVE DAY. MOST
ACTIVE AREA WILL BE IN THE WESTERN PORTIONS ALONG THE MOISTURE
AXIS...BUT WITH MOISTURE INCREASING OVER THE EAST...SHOULD SEE THAT
REGION START TO GET INTO THE ACTION TODAY. ONE FEATURE THAT COULD
ORGANIZE CONVECTION A BIT IS A SHORTWAVE DISTURBANCE CURRENTLY OVER
NORTHWEST NEVADA WHICH IS ALREADY PRODUCING THUNDERSTORMS OVER THAT
AREA. THE 12Z NAM PULLS A PORTION OF THE VORT LOBE ASSOCIATED WITH
THIS FEATURE ACROSS THE UTAH/IDAHO BORDER THIS AFTERNOON.
HOWEVER...THE 06Z GFS KEEPS THIS VORT LOBE OVER NORTHERN NEVADA
TODAY. JUST SOMETHING TO WATCH AS IT MAY IMPACT EXTREME NORTHERN
UTAH IF THE NAM IS CORRECT.

NOT A WHOLE LOT OF PRECIP REPORTED FROM YESTERDAYS STORMS...JUST
SOME ISOLATED REPORTS OF HEAVY RAIN BUT MANY WERE DRIER AND PRODUCED
GUSTY WINDS. WITH THE LOWER LEVELS BEING MORE MOIST TODAY...SHOULD
SEE THESE STORMS BECOME INCREASINGLY WET. STILL...ONLY EXPECT SPOTTY
REPORTS OF HEAVY RAIN TODAY...UNDER THE MOST INTENSE CELLS.

RIDGE STAYS PRETTY MUCH IN PLACE THROUGH THE EARLY PART OF NEXT
WEEK. AN UPPER TROUGH MOVES ACROSS THE NORTHERN INTERMOUNTAIN REGION
DURING THE MIDDLE OF THE WEEK. SHOULD SEE SOME DRYING FROM THE
NORTHWEST LATE IN THE WEEK AS THE FLOW TURNS WESTERLY TO
NORTHWESTERLY BEHIND THIS SYSTEM...BUT QUICK LOOK AT THE GFS SHOWS
THE SYSTEM BEING TOO WEAK RESULT IN MUCH DRYING ACROSS THE SOUTHERN
AND EASTERN PORTIONS.

NO UPDATES TO CURRENT PACKAGE PLANNED.

&&

.FIRE WEATHER...SCATTERED PRECIPITATION YESTERDAY HAS BROUGHT
DEWPOINTS UP INTO THE 40S AND 50S ACROSS THE AREA. WITH THE LOWER
LEVELS BECOMING INCREASINGLY MOIST...EXPECT TO SEE WETTING RAINS
BECOME MORE COMMON OVER THE NEXT COUPLE OF DAYS. HOWEVER...EASTERN
UTAH MAY STILL NEED ANOTHER DAY BEFORE WETTING RAINS PREVAIL.
ISOLATED DRY THUNDERSTORMS COULD SHOW UP OVER OUR NORTHEAST FIRE
WEATHER ZONES LATER THIS AFTERNOON/EARLY EVENING.

&&

.AVIATION...NONE. SEE SLCTAFSLC.
&&

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