What forecasters said that day
The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Pocatello, ID wrote its last area forecast discussion before this winter storm warning went out at Dec 19, 2:46 AM MST, 11 hours 53 minutes earlier.
Area forecast discussion, Dec 19, 2:46 AM MST, 11 hours 53 minutes before
Area Forecast Discussion National Weather Service Pocatello ID 246 AM MST Mon Dec 19 2022 .SHORT TERM...Today through Tuesday night. A broad upper level trough is positioned over the PAC NW this morning with a parent upper low spinning in Alberta. Moisture could arrive in the Central Mountains as early as this afternoon, but most high-res models are suggesting snow onset will be later this evening. There is enough upslope forcing to justify some slight chance PoPs today. Either way, snowfall amounts should be light. NBM 4.1 shows only a 25 to 30 percent probability of 2+ inches in the Sawtooth Range through Tuesday afternoon. Similarly along the Big Hole and Centennial Mountains, upslope flow will result in light snowfall this afternoon with about a 20 to 25 probability of 2+ inches there. On Tuesday night, a strong shortwave will rotate around the upper trough and deepen across the PAC NW. As a result, snow will begin to intensify somewhat, mainly over the higher terrain, and will expand more broadly to lower elevations late Tuesday night. Wind chill temperatures remain in the 20 to 30 below range across the Arco Desert and adjacent valleys at forecast issuance. Current wind chill warning is ongoing through 10 AM today. Hinsberger .LONG TERM...Wednesday through Monday. A strong Canadian low will be starting to drop southward on Wednesday into the Plains. This will help pull moisture south through our area on Wednesday and bring much stronger winds, too. Not only will we see snow and wind, but this system opens up the door for a blast of frigid air behind it on Thursday. Starting with snow on Wednesday, the highest totals are still expected in the mountains. By the time snow is tapering off on Thursday, the NBM 4.1 highlights a 40-65 percent chance of at least 8 inches of snow in the Sawtooths, Bear River Range, and Big Hole mountains. In the Snake Plain, we are looking at about a 15-25 percent chance of at least 2 inches of snow. Then, we have the wind. We can expect fairly widespread gusts of 25-35kts, at least, with higher gusts definitely not out of the question. In fact, the NBM 4.1 shows a 40-60 percent chance of gusts greater than 48kts in the Snake Plain on Wednesday. The uncertainty or current discrepancy between potential versus forecast gusts lies within how well we can get winds to mix down to the surface. After the snow and wind on Wednesday, we get the frigid cold on Thursday. Almost everyone will start Thursday morning below zero. A few spots in the western Magic Valley and southern most Southern Hills could stay a couple of degrees above zero, but those will be the warmest spots. Expect temperatures closer to negative 15-25 anywhere north of Idaho Falls. Wind chills will be even worse, ranging from negative 20 degrees near Idaho Falls to almost negative 40 near the Island Park area. Wind Chill Warnings will likely be needed across much of the area. Thankfully, this cold blast is short- lived as we begin to warm up on Friday and highs head towards the upper 20s to mid 30s by Christmas day. The ECMWF and GFS begin to disagree more as we get into Friday and beyond with the GFS bringing a shortwave through and some more moisture on Friday which the ECMWF is not nearly as excited about at this time. Weak ridging builds in on Saturday, drying us out a bit before another push of moisture arrives arrives in the first half of next week. It would be beneficial to any holiday travel plans to see some dry time Saturday through Monday, so we will stay cautiously optimistic at this time. AMM .Aviation... This morning we are dealing with more BR and HZ than FZFG like yesterday. As such, conditions have generally been VFR/MVFR, but briefly dropping to IFR at times at IDA and PIH. This will continue through the morning with overall VFR/MVFR conditions after 16Z at all sites. Any snow today mostly stays in the higher elevations, so will keep VCSH at DIJ throughout until around 01-02Z timeframe when light snow looks more likely and impactful, dropping VIS to borderline MVFR/IFR conditions. Any light snow at SUN in the same time frame looks light enough to keep VFR conditions, at least through this forecast period. Will introduce some VCSH around the same time at BYI, PIH, and IDA, though confidence is lower. There is quite a bit of dry air to get through for any snow to reach the ground with more moisture not arriving until Tuesday. Winds today won't be too impactful with gusts around 15kts possible. AMM && .HYDROLOGY... ...Extreme Cold Temperatures May Cause River Icing and Rising River and Stream Flows... With single-digit temperatures forecast in the coming week, rivers and streams will continue to ice over. As ice buildup moves downstream, it may cause rapid rise in water levels. As temperatures begin to rise, ice may continue to move downstream. People are urged to use caution along rivers and streams as the rapid increase in flows are dangerous. Keep children and pets away from riverbanks. Those living or recreating near rivers and streams should remain cautious. High stream flows can quickly overpower you and cold water could can lead to hypothermia in minutes. && .PIH WATCHES/WARNINGS/ADVISORIES... Wind Chill Warning until 10 AM MST this morning for IDZ052-068. &&
