Area Forecast Discussion National Weather Service Pocatello ID 151 PM MDT Mon Mar 10 2025 .SHORT TERM...Tonight and Tuesday It's been another gorgeous late winter day across eastern Idaho as the area remains on the northern edge of an area of high pressure. Afternoon visible satellite imagery only shows some fast moving high clouds streaking over the region but otherwise it's a cloud free day for us. A shortwave trough moving well to the north of the region has suppressed the ridge to the south slightly but things remain dry and the tighter pressure gradient has allowed for some breezy conditions across the lower valleys of the Snake Plain and Magic Valley. Winds are gusting in the 20-30 mph range, occasionally higher, but remaining below any wind advisory levels. Temperatures are running well above normal with 50s observed throughout the Snake Plain with a few spots reaching 60 today not entirely out of the question. Forecast highs today have already topped this morning's forecast in many locations as models seemed to underestimate the extent of warming today. Despite the warmup this afternoon, overnight lows will still drop below freezing overnight just about everywhere although a few spots in the lower Snake, Magic Valley and south hills may stay just above 32....barely. Expect another pleasant afternoon tomorrow with similar afternoon temperatures, no precip chances, slightly lighter winds and ample sunshine. Big changes on the way however as we get into the extended portion of the forecast. .LONG TERM...Wed through next Mon night. A breakdown of the upper level ridge from the near term occurs during the day Wed, bring precipitation to the central Idaho mountains during the morning, by Wed afternoon along the northern border with Montana. Overnight, the precipitation spreads southward to encompass the entire forecast area. Overnight lows in the Snake River plain have trended colder, with means more snowfall is possible compared to previous thinking. However, precipitation is very light from Idaho Falls southward even on Wed night. The brunt of the precipitation occurs on Thu/Thu Night, which is when the percentile of snowfall amounts approaches 90th and higher for portions of the forecast area. There are likely to be at least some Winter Weather Advisories for this event, with somewhat high snow levels on Wed. For the rest of the period, minor shortwaves move through a zonal flow. These weak waves are normally not know for run to run consistency, and the risk of precipitation borders on the likely with an occasional period of low chance probabilities for some of the lower elevations. Best thing to say is that it will remain an active pattern to the end of this period. Except for Wed, which is the warmest day as central and eastern Idaho is still in the warm sector of this incoming atmospheric river event, and temperatures will be approaching 60 degrees in the southern hills and nearby eastern Magic Valley. For the rest of the period, lower elevation temperatures hover in the lower to middle 40s and mountain temperatures from the upper 20s to upper 30s. Overnight lows in the 20s for the lower elevations, positive single digits to teens in the mountains. Should be breezy in the Snake River plain/eastern Magic Valley on Wed as the front approaches, then windy at some point on Thu/Thu night, breezy again Fri/Fri night. Windy again For Sat afternoon. The last two days appear normal. Messick && .AVIATION...18Z Monday through 18Z Tuesday. Gusty wind at KPIH and KIDA for the afternoon and early evening, but going light for most during the overnight hours. Sole exception is a continued 10KT-15KT wind at KDIJ from the south. No CIGs expected anywhere, with clouds at around 700mb or so, and then the next cloud deck above 400mb. && .PIH WATCHES/WARNINGS/ADVISORIES... None. &&
