AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SALT LAKE CITY UT 318 PM MDT THU JUL 26 2007 .SYNOPSIS...VERY MOIST AIRMASS OVER UTAH WILL HOVER IN PLACE INTO THE WEEKEND. HIGH PRESSURE ALOFT WILL CONTINUE OVER THE GREAT BASIN THROUGH THE WEEKEND. && .DISCUSSION...MOISTURE PLUME ACROSS THE GREAT BASIN FROM OLD MEXICO NORTH INTO CANADA REMAINS IN PLACE AND WILL SO FOR THE NEXT FEW DAYS AS IT SLOWLY TAKES ON A DRYING TREND. PRECIPITABLE WATER (PW) VALUES REMAIN HIGH ACROSS THE FORECAST AREA...ABOVE AN INCH IN MOST LOCATIONS INCLUDING NORTHWEST UTAH AND NORTHEAST NEVADA WHERE CONVECTION HAS BEEN INITIATED DUE TO GOOD INSOLATION UNDER CLEAR SKIES. MOISTURE WILL SLOWLY DECREASE OVER UTAH THE NEXT FEW DAYS AS HIGH CENTER SETTLES OVER NORTHERN UTAH AND DEEP MOISTURE TENDS TO FLOW AROUND THE PERIMETER OF THE RIDGE. SCATTERED CONVECTION HAS ALSO BEGUN OVER THE SPINE OF UTAH...ESPECIALLY SOUTH...DISPLAYING NO MOVEMENT OR LITTLE MOVEMENT TO THE NORTH. THIS IS DUE TO EMBEDDED WEAK SHORTWAVES DRIFTING THROUGH THE MEAN RIDGE AND THE ABUNDANT MOISTURE.

THIS MONSOON EVENT WILL THEN BE FOLLOWED BY ANOTHER PERIOD OF DRYING FOR THE LATTER PART OF THE WEEK AND ON INTO THE WEEKEND. AS UPSTREAM TROUGH PUSHES ACROSS THE NORTHERN ROCKIES LATE FRIDAY THROUGH SUNDAY...A SOUTHWEST FLOW WILL DEVELOP ACROSS UTAH. GUSTY WINDS WILL EXACERBATE ANY FIRE PROBLEMS PRESENT AT THAT TIME. HOWEVER...WITH THE ABUNDANT MOISTURE EXPECTED PRIOR TO THIS TIME PERIOD...HUMIDITIES WOULD REALLY HAVE TO TAKE A TUMBLE FOR THE AREA TO REACH RED FLAG CONDITIONS. POSSIBLE...BUT NOT LIKELY. && .AVIATION...THERE IS A 20 PERCENT CHANCE OF A THUNDERSTORM DIRECTLY IMPACTING THE SLC TERMINAL. HOWEVER...WITH DEVELOPING CONVECTION TO THE SOUTH OF THE FIELD...THERE IS A GREATER CHANCE OF SOUTHERLY OUTFLOW WINDS THROUGH 03Z. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...NONE.
