The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Glasgow, MT wrote its last area forecast discussion before the first event at Sep 26, 6:11 PM MST, 5 hours 49 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Glasgow MT 711 PM MDT Mon Sep 26 2022 .DISCUSSION... Sent an update this evening simply to fine tune the forecast for clouds and wind for the next 24 hours based on the latest and greatest model consensus I could find. Expecting a calm and comfortable fall evening and overnight. Dry and hot conditions will prevail until a cold front arrives by Thursday night. ----BMickelson Previous discussion: Upper ridging will continue to maintain influence over the western U.S. for the next few days. This will lead to continued dry weather conditions and a warming trend in temperatures. Near record high temperatures are looking quite possible by Thursday. A cold front will track through the region Thursday night as an upper low moves in from the Pacific. Ensemble spread remains quite large over precipitation amounts and placement at this time, but a general cooler and wetter pattern may result over the weekend. && .AVIATION... UPDATED: Sept. 27th, 01:10Z PATTERN: A ridge of high pressure is in control across the region, providing calm and dry conditions. FLIGHT CONDITIONS: VFR. WINDS: Light and variable overnight, then from the southeast Tuesday at 10 to 15 kts with a few higher gusts. ----BMickelson && .GLASGOW WATCHES/WARNINGS/ADVISORIES...NONE. && weather.gov/glasgow
