Area forecast discussion, May 13, 12:10 PM MDT, 3 hours 37 minutes before
Area Forecast Discussion National Weather Service Pocatello ID 1210 PM MDT Wed May 13 2026 .KEY MESSAGES... - Strong to severe thunderstorms with stronger gusts over 60 mph likely through this evening - Outside of showers and thunderstorms, gusts to 55 mph are expected - Much colder weather is coming, especially over the weekend and early next week with widespread frost/freeze conditions && .DISCUSSION... Issued at 1031 AM MDT Wed May 13 2026 An active weather day is under way. As low pressure approaches from the west, we are seeing increasing winds already and will continue into this evening even behind the front. Outside of storms, we are expecting gusts in some cases up to 55 mph. With thunderstorms gusts in excess of 60 mph are likely with gusts over 65 mph possible. Storms should clear by late evening along with stronger wind subsiding. Otherwise, we remain dry until the weekend. Today is the last widespread WELL ABOVE AVERAGE temperature day we will see for a bit. Ahead of the front, especially where downslope is occurring, we are still looking at potentially hitting 90 degrees. We drop to right around AVERAGE for this part of May, before dropping BELOW AVERAGE over the weekend and early next week. Sunday still looks like the coldest day, especially if we can get a deeper low in place, highs are in the 40s and 50s areawide. Overnight lows and more frost/freeze issues are expected to return. We may see some pockets of frost and light freeze until Saturday morning. Beyond that, several morning of widespread frost and freeze conditions are likely. Monday and Tuesday mornings will be the coldest based on the latest trends in the Blend of Models. We are looking at widespread 20s for overnight lows across portions of the Snake Plain and Magic Valley, with the more populated cities barely hitting freezing. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 1203 PM MDT Wed May 13 2026 Winds will be the biggest issue over the next few hours across eastern Idaho as a potent trough moves north of the region. Gusts around 30 kts are likely. Additionally, this feature combined with afternoon heating, will support scattered thunderstorm development over the next few hours. Given the synoptic setup, these storms are not likely to produce precipitation but will likely produce gusty outflow winds in excess of 50-60 kts possible across parts of the region. KPIH, KIDA and KDIJ have the highest potential for winds like this with slightly lower probabilities around KSUN and KBYI. After 14/02Z or so, convective potential drops quickly as cooler air starts to move into the region with an associated cold front. Skies will clear into the day on Thursday but winds will remain breezy overnight and throughout much of the day tomorrow, 15-25 kts or so with higher gusts. && .PIH WATCHES/WARNINGS/ADVISORIES... Wind Advisory until 10 PM MDT this evening for IDZ051>057- 067>070-075. && DISCUSSION...Keyes AVIATION...McKaughan
