032 FXUS65 KPIH 051804 AFDPIH Area Forecast Discussion National Weather Service Pocatello ID 1204 PM MDT Fri Jun 5 2026 .KEY MESSAGES... -Hot and dry conditions expected today. -Breezy to gusty winds continue each afternoon through the weekend. -Next shower/storm chance returns late Saturday into Sunday as slow- moving cold front passes through the area. && .DISCUSSION... Issued at 256 AM MDT Fri Jun 5 2026 Weak high pressure is sitting over Eastern Idaho this morning leading to almost no cloud cover and certainly nothing of interest on radar. It is almost more of a zonal flow early this morning before we get into southwest flow aloft this afternoon. Once we do, temperatures will jump quickly (though it`s not too difficult of a jump when many are already in the mid to upper 50s) into the 80s. We will be nearing the 90 degree mark in parts of the eastern Magic Valley, lower Snake River Plain, and South Hills today. Winds are a bit lighter today and it looks like we`ll stay just below any LAKE WIND ADVISORY criteria at the American Falls Reservoir. Strongest wind gusts will be in the Central Mountains and out across the Arco Desert/Mud Lake area with gusts around 35 mph and stronger on ridge tops. Gusts will actually be a bit lighter in the eastern Magic Valley, South Hills, and Snake River Plain ranging from 20 to 30 mph. Our next system begins to move into the area for the weekend with an area of low pressure over southern Canada and the Pacific Northwest and an associated slow-moving cold front passing through eastern Idaho. This will bring about isolated to scattered showers and thunderstorms late Saturday into Sunday. There still isn`t much in the forecast for liquid precipitation, but there are at least a couple of hundredths for the norther portions of the Central Mountains and the Eastern Highlands. Gusty winds will be in full force for Saturday and Sunday thanks to the cold front and it seems plausible that we will need WIND ADVISORY headlines at some point as gusts reach 35 to 45 mph and a few spots to nearly 50 mph. The weekend system will drop our afternoon highs by about 5 degrees for Saturday and a much bigger drop for Sunday when we may not even make it out of the 60s! We get a bit of a break in the activity on Monday before another system arrives late Tuesday into Wednesday and brings better chances for widespread rainfall which we so desperately need. && .AVIATION /18Z TAFS THROUGH 18Z SATURDAY/... Issued at 1200 PM MDT Fri Jun 5 2026 Widespread VFR this afternoon through Saturday morning. Winds will be 10 to 15 knots this afternoon at PIH, IDA and DIJ. Will have clear skies. Winds die down tonight. Expect a wind increase last Saturday morning as a cold front approaches with 15 gusting to 25 expected after 17Z at PIH, IDA and DIJ. Will see an increase in mid and high level clouds. && .FIRE WEATHER... Issued at 256 AM MDT Fri Jun 5 2026 Weak high pressure over the area early this morning brings about a quiet start to the day, but we will see increasing wind gusts again this afternoon and dry conditions, though winds will be a bit lighter than yesterday. As such, we will see NEAR CRITICAL fire weather conditions with low min RHs and said breezy winds as temperatures also increase this afternoon. A slow-moving cold front begins to move into eastern Idaho late tonight and will bring even stronger winds to the area for the weekend. The chance for a wetting rain this weekend looks mostly confined to the northern portions of the Central Mountains and parts of the Eastern Highlands. It`s not until next Tuesday into Wednesday that we see the potential for more widespread wetting rains as a stronger system arrives. && .PIH WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...AMM AVIATION...GK FIRE WEATHER...AMM
