AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
305 PM MDT FRI JUN 30 2006

.SYNOPSIS...A MOIST RIDGE OF HIGH PRESSURE WILL REMAIN OVER THE AREA
THROUGH THE WEEKEND. SOME DRYING AND WARMING WILL BEGIN EARLY NEXT
WEEK.

&&

.DISCUSSION...SCATTERED CONVECTION HAS BROKEN OUT THIS
AFTERNOON...MAINLY OVER THE HIGHER TERRAIN. PRECIPITABLE WATER
VALUES ARE HIGH ENOUGH OVER THE ENTIRE AREA THAT CELLS COULD PRODUCE
LOCALLY HEAVY RAIN THIS EVENING. STORMS OVER THE NORTH ARE MOVING
ALONG ENOUGH THAT REPEAT CELLS WILL BE REQUIRED TO CAUSE
PROBLEMS...BUT IN SOUTHERN UTAH THE CELLS ARE MOVING VERY SLOWLY OR
JUST REDEVELOPING ALONG OUTFLOW BOUNDARIES. SURFACE DEWPOINTS ARE
NOT QUITE HIGH ENOUGH TO JUSTIFY A FLASH FLOOD WATCH IN THE
SOUTH...BUT WILL HAVE TO MONITOR RADAR RAINFALL ESTIMATES CLOSELY
OVER THE NEXT 4 TO 6 HOURS.

MODELS INDICATE LITTLE CHANGE IN THE PATTERN SAT/SUN WITH A HINT OF
SOME DRYING OVER THE NORTH BUT NOT MUCH CHANGE IN THE AIRMASS OVER
THE SOUTH. HAVE TRENDED POPS DOWN OVER THE NORTH BUT KEPT THEM IN
THE CHANCE...VALLEYS...TO NEAR 50 PERCENT OVER THE MOUNTAINS OF THE
SOUTH. TEMPERATURES DO NOT CHANGE MUCH NEXT TWO DAYS.

DRIER AND WARMER INDICATED MON/TUES WITH SOME THREAT OF THE FIRST
100 DEGREE MAX TEMP AT SLC ON TUESDAY. TRENDED POPS DOWN AND
TEMPERATURES UP.

GFS CONTINUES TO PREDICT THE 500 MB HIGH CENTER TO REDEVELOP
NORTHEAST INTO WYOMING WED/THU. THIS BRINGS A DEEP MOIST SOUTHEAST
FLOW INTO THE AREA LATE WED AND INTO THU WITH A WELL DEFINED WAVE
EMBEDDED IN THE FLOW.  THIS WOULD BE A WIDESPREAD RAIN EVENT FOR THE
AREA WITH MUCH COOLER TEMPERTURES ON THU. PRETTY FAR OUT FOR A LOT
OF CONFIDENCE IN THIS SOLUTION...BUT WE HAVE SEEN THE SAME BASIC
MESSAGE FOR 3 RUNS IN A ROW AND 12Z EC ALSO MOVES THE 500 HIGH
CENTER INTO WYOMING...SO HAVE TRENDED POPS UP AND TEMPS
DOWN...ESPECIALLY ON THU.

&&

.AVIATION...THUNDERSTORM ACTIVITY THUS FAR HAS REMAINED CONFINED
WELL SOUTH OF KSLC...AND RADAR/SATELLITE TRENDS INDICATE THIS
ACTIVITY CONTINUES TO GRADUALLY SPREAD SOUTH AWAY FROM THE TERMINAL.
ANY CHANCE OF THUNDERSTORMS IMPACTING KSLC WILL LIKELY HOLD OFF
UNTIL NEAR/AFTER 04Z...AND BE ASSOCIATED WITH ACTIVITY CURRENTLY
OVER EASTERN NV. THERE IS A 20 PERCENT CHANCE THIS ACTIVITY WILL
HOLD TOGETHER AS IT CROSSES WESTERN UTAH THIS EVENING...REACHING
KSLC AROUND 04Z OR SO.

&&

.FIRE WEATHER...LIGHT WINDS AND A MODERATELY MOIST AIRMASS WILL
SUPPORT AFTERNOON AND EVENING CONVECTION TONIGHT AND SATURDAY. CLOUD
COVER...HUMIDITY... ESPECIALLY OVERNIGHT RH RECOVERY...WILL BE HIGH
SUNDAY MORNING. A DRYING TREND WILL THEN DEVELOP...ESPECIALLY FOR
THE WESTERN PORTIONS...FROM SUNDAY AFTERNOON THROUGH MID-WEEK.
ANOTHER ROUND OF DEEP MOISTURE IS THEN EXPECTED TO MOVE OVER THE
FIRE DISTRICT LATE NEXT WEEK.

&&

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