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. && DUNN/SEAMAN/GIBSON
