AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
244 PM MDT SUN JUL 30 2006

.SYNOPSIS...UPPER HIGH WILL CONTINUE TO MOVE EAST AND SETTLE OVER
THE PLAINS STATES OVER THE NEXT COUPLE OF DAYS. AIRMASS WILL REMAIN
MOIST INTO THE EARLY PART OF THE COMING WEEK. A WEAK COLD FRONT WILL
MOVE THROUGH NORTHERN UTAH EARLY TUESDAY.

&&

.DISCUSSION...SHORTWAVE OVER SOUTHERN UTAH THIS MORNING TRACKING TO
THE NORTHEAST. CONVECTION DEVELOPING ACROSS CENTRAL UTAH AND SHOULD
CONTINUE THROUGH THE EVENING HOURS. NOTHING OVER NORTHWEST UTAH AT
THIS TIME AND MAY NOT SEE MUCH AS MOST ENERGY WITH THE SHORT WAVE
REMAINS TO THE EAST OF THE WASATCH FRONT AND NORTHWEST DESERT.
LOWERED POPS OVER THE NORTHWEST THIS EVENING.

THUNDERSTORMS OVER SOUTH CENTRAL UTAH ARE MAINLY OVER THE MOUNTAINS
AND ARE DRIFTING SLOWLY TO THE NORTHEAST. POTENTIAL FOR HEAVY
RAIN IN SOME OF THESE STORMS IS PRESENT. MAIN AREA OF CONCERN IS
ALONG NORTHERN KANE COUNTY WHERE THUNDERSTORMS HAVE DEVELOPED AND
ARE MOVING VERY SLOWLY TO THE EAST. NOTHING OVER THE FAR SOUTHWEST AS
OF YET...ALTHOUGH ISOLATED THUNDERSTORMS OVER NORTHWEST ARIZONA
ARE HEADING FOR UTAH AND WILL PROBABLY CROSS INTO UTAH LATER THIS
AFTERNOON. DUE TO THE DEVELOPMENT FARTHER TO THE EAST TODAY HAVE
UPDATED THE FLASH FLOOD POTENTIAL RATING TO MODERATE OVER THE
SOUTHEAST.

UPPER TROUGH EXPECTED TO MOVE ON SHORE MONDAY AND TURN WINDS OVER
UTAH TO THE SOUTHWEST LATER MONDAY. ENOUGH MOISTURE WILL REMAIN
MONDAY FOR AFTERNOON AND EVENING CONVECTION MAINLY OVER THE
MOUNTAINS. TROUGH THEN CONTINUES EASTWARD KEEPING RIDGE OVER THE
GREAT PLAINS AS IT SLIDES OVER THE TOP OF THE RIDGE AND PUSHES
THROUGH THE NORTHERN PORTION OF THE STATE. WEAK FRONT LOOKS TO BE A
LITTLE SLOWER AND PROBABLY WONT PUSH INTO UTAH UNTIL TUESDAY MORNING.
ADJUSTED POPS ACCORDINGLY.

WESTERLY FLOW WILL DOMINATE FOR THE REST OF THE WEEK AS NEXT
OCCASIONAL WEAK EMBEDDED SHORTWAVES KEEP THE RIDGE FROM REBUILDING
OVER THE INTERIOR WEST. SEASONAL OR BELOW NORMAL TEMPERATURES ARE
EXPECTED THROUGH THURSDAY AND WITH PATCHY MOISTURE AROUND ISOLATED
CONVECTION NOT OUT OF THE QUESTION. RIDGE MAY BEGIN TO MOVE BACK
WESTWARD AS NEXT WEAK TROUGH BEGINS TO DEVELOP OVER PACIFIC
NORTHWEST. THIS WILL ALLOW TEMPERATURES TO INCH UPWARD AS MOISTURE
BEGINS TO SEEP BACK INTO THE STATE FROM THE SOUTH.

&&

.AVIATION...LAKE BREEZE CAME IN EARLY TODAY AND WILL CONTINUE THROUGH
MID EVENING. BEST CHANCE FOR THUNDERSTORMS AT KSLC APPEARS TO BE
BETWEEN 22Z AND 03Z AND COULD POSSIBLY GO LONGER. LAND BREEZE SHOULD
RECLAIM DOMINANCE AROUND 04Z.

&&

.FIRE WEATHER...DRIER AIR IS STARTING TO WORK ITS WAY INTO NORTHWEST
UTAH. ONLY EXPECT A 10 PERCENT CHANCE OF ANY THUNDERSTORMS MAKING IT
OVER THE KSLC TERMINAL TODAY. IF THUNDERSTORMS DO OCCUR...THIS WILL
LIKELY HAPPEN BETWEEN 23Z AND 03Z. WINDS MAY STAY OUT OF THE
NORTHWEST UNTIL 04-05Z TONIGHT DUE TO A NORTHWESTERLY SURFACE
PRESSURE GRADIENT.
