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 Jan 31, 9:24 PM MST, 2 hours 36 minutes earlier.
Area Forecast Discussion National Weather Service Glasgow MT 924 PM MST Tue Jan 31 2023 .DISCUSSION... Evening Update: Forecast elements remain on track in the near term so minimal changes were made at this time. Radar continues to show reflectivity across NE Montana largely associated with midlevel cloud and virga, though an isolated flurry or snow shower cannot be entirely ruled out tonight. Previous Discussion: Lingering clouds on satellite imagery and light returns on radar imagery indicate the off chance for virga snow showers or flurries across southern Saskatchewan gliding over the far NE zones of Montana this afternoon and evening. Otherwise, the forecast is rather benign. The departing colder air will allow warmer air from the SW to move over our region through tomorrow. Dangerously cold wind chills will not be a factor tonight. Wednesday, near normal temperatures in the north and above normal temperatures in the south can be expected under a building ridge of high pressure. Wednesday night into Thursday, a quick-passing cold front will drop the temperatures back down to below zero in the north. Another round of Wind Chill Advisories may be needed. Friday and beyond, the full strength of the warm upper-level ridge will be realized from the south as daily high temperatures climb above freezing. Chances for any precipitation will be few and far between, probably isolated to early next week, resulting in only trace amounts. ----BMickelson && .AVIATION... PATTERN: Colder air mass is slowly moving away (toward the NE) from our region, allowing warmer temperatures to slowly make a come back. FLIGHT CONDITIONS: VFR will prevail with some SCT to BKN mid clouds expected. WINDS: From the W and NW around 10 kts, becoming calm overnight. ----BMickelson && .GLASGOW WATCHES/WARNINGS/ADVISORIES...NONE. && weather.gov/glasgow
