Flash Flood Warning 6, NWS Salt Lake City, UT

AREA FORECAST DISCUSSION...CORRECTED HEADLINES
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
230 PM MDT THU APR 8 2004

.SYNOPSIS...A MOIST AND UNSTABLE AIRMASS WILL REMAIN OVER THE AREA
THIS EVENING. THE AIRMASS WILL BEGIN TO DRY FROM THE NORTHWEST
AFTER MIDNIGHT. COLDER AIR AND SOME PRECIPITATION WILL MOVE IN FROM
THE NORTH BEGINNING TOMORROW AFTERNOON WHEN A WEATHER SYSTEM
SLIDES ACROSS EASTERN UTAH.
&&

.DISCUSSION...SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE THIS
AFTERNOON AND EVENING AS A SHORT WAVE CONTINUES TO MOVE SOUTH.
PARTIAL CLEARING WILL OCCUR AFTER MIDNIGHT BETWEEN THIS WAVE AND THE
NEXT ONE WHICH IS EXPECTED TO MOVE ACROSS MAINLY EASTERN UTAH FRIDAY
AFTERNOON. THE FLASH FLOOD WATCHES FOR SANTAQUIN...SPRINGVILLE AND
THE FARMINGTON BURN AREAS WILL BE CONTINUED UNTIL MIDNIGHT THIS
EVENING AS SHOWERS AND THUNDERSTORMS CONTINUE TO DEVELOP ALONG AND
AHEAD OF THE SHORT WAVE. BAND OF MOISTURE THAT MOVED THROUGH THE
NORTHERN WASATCH FRONT THIS MORNING HAS SPREAD SOUTHWARD AND WILL
SETTLE OVER THE CENTRAL AND SOUTHERN PORTION OF THE STATE THROUGH
THIS EVENING. RAISED POPS OVER THE SOUTHERN MOUNTAINS AS CONVECTION
WILL PROBABLY PERSIST THROUGH THE MORNING HOURS IN THAT AREA.

THE NEXT SHORTWAVE WITH COOLER AIR WILL DROP INTO UTAH FROM THE NORTH
ON TOMORROW AFTERNOON. NEW MODELS AGREE THAT THIS SYSTEM WILL AFFECT
MAINLY THE EASTERN PORTION OF THE STATE AND THE MOUNTAINS. THE ETA
STILL LAGS THE GFS BY A FEW HOURS...ALTHOUGH THIS SHOULD NOT
INTERFERE TOO MUCH WITH TIMING. I THINK THAT THE MODELS HINT THAT
PRECIPITATION WILL EXTEND A LITTLE FARTHER WEST FOR TOMORROW AND HAVE
RAISED POPS A BIT FOR SALT LAKE CITY FOR TOMORROW AFTERNOON AND
EVENING. MOISTURE THEN SPREADS SOUTHWARD ACROSS MUCH OFF SOUTHERN
UTAH THROUGH SATURDAY MORNING. RAISED POPS OVER THE SOUTH FOR FRIDAY
NIGHT AND OVER THE SOUTHWEST SATURDAY MORNING. DRYING WILL START
SATURDAY AFTERNOON AND CONTINUE INTO SUNDAY WITH ANY SHOWERS CONFINED
TO THE EASTERN MOUNTAINS. WINDS WILL REMAIN NORTHERLY THROUGH SUNDAY
WITH AN EASTERLY COMPONENT SETTING UP OVER THE NORTHERN MOUNTAINS
SATURDAY MORNING. SPEEDS WILL NOT BE GREAT ENOUGH TO CAUSE ANYTHING
OTHER THAN SOME SLIGHTLY ENHANCED CANYON WINDS.

DRY NORTHWEST FLOW WILL THEN TAKE OVER ACROSS THE AREA AS STRONG
RIDGE BEGINS TO MOVE INTO THE GREAT BASIN FOR THE REST OF SUNDAY
AND INTO NEXT WEEK. THIS STRONG DRY RIDGE WILL REMAIN OVER UTAH
THROUGH MUCH OF THE WEEK. SOUTHWEST WINDS WILL BEGIN TO INCREASE AS
RIDGE AXIS MOVES EAST OF THE STATE ON WEDNESDAY AND NEXT SYSTEM MOVES
INLAND. MODELS HINT AT MOISTURE BEGINNING TO INCREASE THURSDAY OVER
THE NORTH AND HAVE TRENDED THAT DIRECTION.
