Area Forecast Discussion National Weather Service Pocatello ID 240 PM MDT Fri Jun 7 2024 .SHORT TERM...Tonight through Saturday Night. Early afternoon satellite imagery shows a broad H5 ridge in place over the WRN CONUS as a H5 shortwave trough works east across the NRN Great Basin. This trough will be the main driver of convection today with radar imagery as of 2 PM showing scattered to numerous thunderstorms developing across Utah and Nevada with more isolated activity across the CNTRL Mountains. Convective initiation in CNTRL and ERN Idaho will take place between 2-5 PM with a mix of isolated to scattered thunderstorms expected to develop which will continue through this evening ahead of dry conditions returning overnight. The convective environment today is represented well on the HREF model with shows 300-600 J/kg of SBCAPE and 20-30 kts of 0-6 km shear with both the HRRR/NAM models showing 7-9 degree/km 700-500 mb lapse rates. These conditions will remain favorable for microbursts and strong outflow winds in addition to small hail and brief moderate to heavy rain with the primary hazard centering around strong wind gusts in excess of 40-50 mph. The HREF model probability of sustained winds greater than 34 mph shows a 50- 70% chance across the Snake River Plain south into Utah/Nevada with the HREF ensemble max wind gusts today showing potential for up to 40-60 mph. As Friday's H5 shortwave trough works east into Wyoming for Saturday, a secondary shortwave will fill in behind but will carry less moisture with it and as a result, support less thunderstorm chances across SRN Idaho. For a comparison, the 24-hour HREF probability of thunder Friday shows around a 40-70% chance everywhere outside the CNTRL Mountains while the probability on Saturday drops to a 10-20% chance regionwide with a 20-40% chance across Cassia County. Stronger storms Saturday will again support strong wind potential but to a lesser extent versus Friday with the HREF model probability of sustained winds greater than 34 mph showing a 10-30% chance. The HREF ensemble max wind gusts Saturday show potential for up to 30-40 mph. Courtesy of high pressure overhead through the start of the weekend, temperatures will remain seasonably warm with highs in the upper 70s to low 90s each day and overnight lows in the 40s/50s/60s. Outside of any thunderstorm outflow winds, synoptic winds will remain on the lighter side staying less than 20 mph each day. MacKay .LONG TERM...Sunday through next Friday. The most active and impactful weather in the long term will be Sunday through Monday where a Pacific system will bring the most widespread shower and thunderstorm activity. Have some widespread amounts over 0.10 inches in the two day period. Temperatures will remain very warm Sunday with low elevations highs in the upper 80s. It will be much cooler Monday with highs mainly in the 70s to around 80. A dry zonal flow will set up Tuesday through Thursday and expect dry conditions with some breezy conditions expected especially in the Snake River Plain. Temperatures will remain above normal through the long term with a warming trend Tuesday into Thursday with highs 70s mountains and 80s valleys with some low elevations near 90 by Thursday. Will see an increase in the chance for convection and showers and thunderstorms Friday mainly in the eastern mountains. Highs likely remaining in the 70s and 80s. GK && .AVIATION...For the 18Z TAFS through 18Z Saturday. Main impact will be thunderstorm development after 20Z and continuing through much of the evening. Have vicinity at all sites and expect best chances at site to be at BYI as brunt of activity in southern regions, but the threat will be at all sites. Main impacts will be wind gusts near any thunderstorm outflow where gusts may exceed 30 knots with a low chance of 50 knots right under a storm. Thunderstorms will end overnight with again isolated development Saturday afternoon. GK && .FIRE WEATHER... Warm weather will produce minimum humidity values in the upper teens to mid 20s through the weekend. Isolated thunderstorms remains possible through Saturday. A cold front will arrive late Sunday which will produce better chances for thunderstorms Sunday afternoon and Sunday night. GK && .HYDROLOGY... A FLOOD WARNING is now in effect for the Teton River near Driggs as small streams/creeks and the main stem river continue to run high. Minor flooding is in the forecast starting tonight on the main stem river and is expected to remain at that level through much of next week, aided by additional snowmelt from the Tetons and Big Holes. Further downstream along the Teton River near St. Anthony, that gage is also nearing action stage and is forecast to reach that tonight and remain elevated into next week. Several other rivers across the CNTRL Mountains are also seeing diurnal increases with the Big Lost River at Howell Ranch currently hovering around action stage. Along the Snake River, increased flows out of Palisades Reservoir has also led to the Snake River near Heise gage climbing up to action stage and it is expected to stay there for at least the next week.
