044 FXUS65 KPIH 270429 AFDPIH Area Forecast Discussion National Weather Service Pocatello ID 1029 PM MDT Sat Apr 26 2025 .KEY MESSAGES... - Showers and thunderstorms possible most days this week - Cooler first half of the week, warming for Thursday and Friday - Another chance at more widespread rain next weekend && .SHORT TERM /THROUGH SUNDAY NIGHT/... Issued at 152 PM MDT Sat Apr 26 2025 Satellite imagery shows deep upper low over central California, with southerly flow pulling moisture north across East Idaho. Showers and a thunderstorm or two remain possible this afternoon and evening mainly across the central mountains and portions of the eastern highlands. Rest of the forecast area stays dry today including the Snake Plain. Gusty southerly winds in place today helping to maintain very warm temperatures in places, along with a steep dew point depression. Additional moisture shifts north overnight tonight, with potential for showers early in the day across the southern highlands and into the Snake Plain. There are differences in the high-res models regarding the potential, so confidence not particularly high. Much better chances for thunderstorms exist again around the periphery of the forecast area, likely limited across the south and through the Snake Plain given potential for early cloud cover to limit instability. Temperatures cool slightly for Sunday. && .LONG TERM /MONDAY THROUGH SATURDAY/... Issued at 152 PM MDT Sat Apr 26 2025 Low pressure will continue to shift east of Idaho on Monday. We will see some rain and mountain snow showers drop in from the north behind it for most of the day and into the evening. With the track of the low, we continue to see two main areas for heavier precipitation, one across the central mountains and the other across the eastern highlands. The overall track though has shifted north at the moment to pull heavier rain and snow out of the southeast corner. Higher amounts in those spots are pushing 1.0-1.25" and even higher locally. Probability forecasts show a 5-15% chance of more than 1.25" occurring. Snow amounts above 7000ft will exceed 6" in those bands, and mostly likely those amounts and higher will be higher than pass level. On the flip side, trace amounts of slushy snow are possible down closer 6000ft. Beyond that, a couple of weaker storms will bring quick shots of lighter moisture totals our way. The next "big" chance comes by next weekend. Highs quickly rebound back into the 60s and 70s once we get past Monday. && .AVIATION /06Z TAFS THROUGH 06Z MONDAY/... Issued at 1026 PM MDT Sat Apr 26 2025 Upper low approaches Sunday from the south and expect winds to again increase at PIH and IDA mainly with 15 knot sustained winds with gusts to 25 knots in the afternoon. Expect most rain shower activity to be at DIJ and SUN and have predominant showers there 18Z through 03Z. Only have vicinity showers at this point for PIH, BYI and IDA after 18Z. Winds will die down at all locations after 01Z Sunday evening. && .PIH WATCHES/WARNINGS/ADVISORIES... None. && $$ SHORT TERM...DMH LONG TERM...Keyes AVIATION...GK
