Area Forecast Discussion National Weather Service Pocatello ID 1134 AM MDT Sat Apr 11 2026 .KEY MESSAGES... - Precipitation chances increase as we head further into the weekend. - 20 to 30 percent chance of thunderstorms for most of Southeast Idaho today and Sunday. Thunderstorms will be capable of producing 50 mph wind gusts. - Cooler temperatures by Monday and remaining seasonable. && .DISCUSSION... Issued at 127 AM MDT Sat Apr 11 2026 Moisture will continue to lift into Idaho in southwest flow aloft with the next closed low shifting eastward into northern CA by tomorrow. Increased cloud cover today will limit daytime heating, meaning daytime highs will max out in the mid-60s across the low elevations which is about 10 degrees cooler than yesterday. As the center of low pressure continues shifting eastward, chance of precipitation and thunderstorms will increase in both probability and areal coverage as we head further into the weekend with showers continuing into next week. Probability of thunder will nearly reach 20 percent or greater areawide this afternoon, with closer to 30 percent chance across central and south-central Idaho. HREF ensemble max wind gusts indicate thunderstorm outflows will be capable of producing 50 to 55 mph gusts both today and Sunday. Outside of thunderstorms, wind gusts will range 30 to 40 mph both today and tomorrow with breezy to windy conditions persisting into the early part of next week. Daytime temperatures tomorrow are now looking similar to what we're expecting for today, finally turning more seasonable by Monday and through the first half of next week. Liquid accumulation through late tonight will generally range a few hundredths to 0.15" with the central mountains and Centennial Mountains/Island Park region receiving closer to a quarter of an inch to half an inch. Additional accumulation tomorrow through Tuesday will be one tenth to 0.20" across the Snake River Plain, generally 0.20" to 0.40" across the eastern and southern highlands with locally higher total in the mountains, and half an inch to three quarters of an inch in the central mountains with locally higher amounts along the highest peaks. Snow levels will drop closer to 7,000 feet tomorrow and continue to fall into early Monday, allowing for modest snow accumulation up to about 5 inches above 6,500 feet with several additional inches in the highest elevations. Most mountain passes are forecast to receive 2 inches or less, with the exception of Banner and Galena Summits which are forecast to receive approximately 5 inches through Tuesday. Flow aloft looks to briefly turn zonal mid-week in the wake of the departing trough and ahead of the next low descending from Canada. Models are still sorting out the upper-level details heading into the latter half of next week, but the pattern will remain at least unsettled through the entirety of the extended period. && .AVIATION /18Z TAFS THROUGH 18Z SUNDAY/... Issued at 1134 AM MDT Sat Apr 11 2026 A broad area of showers is moving through East Idaho late this morning with a mix of CIGS ranging from VFR to IFR. Winds are also highly variable, currently with gusts peaking around 25kts ahead of the convection. Conditions are still expected to destabilize this afternoon with ISOLD to SCT TSRA, with gust potential around or slightly exceeding 50kts. Maintained PROB30 during the most likely hours for TSRA. After a quiet overnight period, conditions look very similar on Sunday. && .PIH WATCHES/WARNINGS/ADVISORIES... None. && DISCUSSION...Cropp AVIATION...DMH
