NWS Salt Lake City, UT wrote its last area forecast discussion before the first event at Jul 25, 1:30 PM MST, 5 hours 28 minutes earlier.
UTAH AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SALT LAKE CITY UT 230 PM MDT THU JUL 25 2002 .SYNOPSIS...A MOIST AND UNSTABLE AIRMASS WILL REMAIN OVER THE AREA THIS EVENING. AN INCREASING WESTERLY FLOW ALOFT WILL HELP DRY OUT THE AREA FOR FRIDAY AND THE WEEKEND. .DISCUSSION...CONVECTION HAVING A HARD TIME GETTING GOING UNDER SUBSIDENCE FROM LAST NIGHTS SHORTWAVES. STILL EXPECT IT TO DEVELOP TO SCATTERED COVERAGE IN THE LATE AFTERNOON/EVENING HOURS. SHORTWAVE MOVING THROUGH EASTERN OREGON WILL ALSO PUSH THE LOBE THAT EXTENDS FORM EASTERN ID INTO CENTRAL NV ACROSS THE NORTHERN/CENTRAL SECTIONS OF THE AREA TONIGHT. 18Z ETA SHOWS QUITE A BIT OF ACTIVITY CONTINUING WITH THIS IMPULSE THROUGHOUT THE NIGHT. SO ALTHOUGH WILL WAIT UNTIL ISSUE TIME TO DECIDE FOR SURE ON EVENING POPS EXPECT TO NOT CHANGE TOO MUCH FOR TONIGHT AND TO REMOVE ANY EVENING REFERENCES FOR THE NORTHERN 2/3 OF THE AREA. EXPECT THE MOUNTAINS TO GENERATE SCATTERED ACTIVITY AGAIN TOMORROW BEFORE DRYING SPREADS IN. A NORTHERN BRANCH SHORTWAVE PUSHES ACROSS MOST OF THE AREA LATE SATURDAY NIGHT/SUNDAY. IT MAY PROVIDE ENOUGH HELP TO TRIGGER SOME LIMITED CONVECTION OVER THE NORTHERN MOUNTAINS. WILL KEEP A SLIGHT CHANCE IN OUR ID/WY BORDER ZONES TO REFLECT THIS. OTHERWISE THE MAIN EFFECT WILL BE A LITTLE ADDITIONAL COOLING FOR SUNDAY INTO MONDAY. THE 12Z PSEUDO AVN DATA FROM THE NAVY NOGAPS LOOKS LIKE THIS WOULD BE A LITTLE SHARPER AND POSSIBLY A BIT SLOWER TROF. BUT LITTLE CONFIDENCE IN THAT TREND GIVEN THAT THE NOGAPS PERFORMANCE HERE HASNT BEEN VERY GOOD. ONCE THAT SHORTWAVE GOES WE STAY IN A DRY NORTHWEST FLOW WITH A HIGH CENTER TO OUR WEST FOR A COUPLE OF DAYS. THE HIGH TENDS TO DRIFT EAST BY MIDWEEK AS ANOTHER SHORTWAVE PUSHES THROUGH THE NORTHERN GULF OF ALASKA. THAT WILL RESULT IN SLOWLY WARMING TEMPERATURES AND BY LATE WEDNESDAY OR THURSDAY COULD BE FAR ENOUGH EAST TO LET SOME MOISTURE START SEEPING BACK IN FROM THE SOUTH. FOR WILL KEEP THURSDAY DRY SINCE ANY ACTIVITY THAT MIGHT DEVELOP SHOULD STILL BE QUITE LIMITED. SLC 3--1 CDC 3--0 SANDERS .SLC...NONE
