NWS Glasgow, MT wrote its last area forecast discussion before the first event at Jun 9, 7:38 PM MST, 2 hours 32 minutes earlier.
Area Forecast Discussion National Weather Service Glasgow MT 838 PM MDT Sun Jun 9 2019 .DISCUSSION... Update: Showers and thunderstorms that developed this afternoon with unstable airmass and shortwave are now diminishing with the setting sun. Skies will clear later this evening as the wave moves to the east and atmosphere stabilizes. Outflows from the scattered storms this evening have made winds variable across the region. The winds will become light and variable after sunset. Will update forecast this evening after the remaining showers dissipate. Forrester Previous discussion: Beginning today, the flow pattern sets up consistently from the northwest, with small embedded disturbances bringing occasional chances for showers and thunderstorms to portions of northeast Montana over the next several days. Many models have differing ideas where and when the resulting precipitation will occur. Tried to blend with the best model consensus I could find, leaning toward an overall wetter solution, to avoid some of these sneaky summer-time thunderstorms than can easily develop in this flow pattern. Wednesday into Thursday: Just as the western states ridge of high pressure begins to build eastward toward our region, multiple disturbances from the Canadian west coast and the Canadian Rockies break down that ridge and throw the models out of sync with each other leading into the next weekend. Overall, beginning on Friday, a more active weather pattern looks possible, with more impactful and more organized thunderstorms. BMickelson && .AVIATION... Synopsis: NW flow aloft continues for the next few days. Some mid level clouds will linger this evening as any remaining showers dissipate by 04z. Skies will be mostly clear late tonight. Daytime cumulus will develop during the day on Monday with isolated showers possible in the late afternoon. Flight Conditions: VFR. Winds: Winds will be light and variable overnight. West winds 5 to 10 knots will develop Monday morning and continue into the evening. && .GLASGOW WATCHES/WARNINGS/ADVISORIES...NONE. && weather.gov/glasgow
