992 FXUS65 KTFX 130530 AFDTFX Area Forecast Discussion National Weather Service Great Falls MT Issued by National Weather Service Missoula MT 1130 PM MDT Sun Jul 12 2026 Aviation Section Updated. .KEY MESSAGES... - Very warm afternoon temperatures likely most days this week. - Daily chances for showers/thunderstorms. Some storms could be severe or produce heavy rainfall. && .UPDATE... /Issued Issued by National Weather Service Missoula MT/ A front has swept through much of the area this evening., resulting in a northwesterly wind shift. Remaining areas where the front has not gone through will see the threat for strong wind gusts from showers and storms persist for another hour or two. The update adds some shower mentions on the plains east of a Havre to Lewistown line for a couple more hours. No other changes were made at this time. -AM && .DISCUSSION... /Issued Issued by National Weather Service Missoula MT/ - Meteorological Overview: The summer time upper level ridge of high pressure that has developed over the Western US, will generally reside over the Western US over the next week or so, just varying in how high of an amplitude it gets over Montana. The amplitude of the ridge will have some determination on hot it gets daily over the CWA. For tonight, a weak upper level disturbance will move from southeast to northeast through the CWA. Because max temps this afternoon will be in the mid 90s, there is some potential some storms could produce strong wind gusts. For Mon through next Sun...max daily afternoon temperatures will generally be above normal most days. Afternoon temperatures should not be quite as hot as this past weekend, but still very warm most days. There will also be daily chances for showers/thunderstorms as upper level disturbances rotate around the upper level ridge. Some of the storms could be severe with isolated heavy rainfall possible from some storms as well. - Forecast Confidence & Scenarios: With inverted V soundings this afternoon, any down drafts from thunderstorms could produce strong wind gusts. Thus a marginal for severe storms was placed for areas around Chinook and Harlem. Brusda && .AVIATION... 13/06Z TAF Period A southwesterly flow aloft will stream variable mid to high level clouds and moisture across the region with VFR conditions prevailing. A few light showers with VFR cloud bases remain possible tonight, mainly across western portions of north-central MT. On Monday, widely scattered shower and thunderstorm development is expected across southwest MT in the afternoon with gusty showers/thunderstorms tracking northeast into central/north- central MT Monday evening. Gusty northwest surface winds across eastern portions of north-central MT and at some SW MT terminals initially tonight will decrease with mainly light winds by 10z. Surface winds become east to southeasterly at terminals on Monday. Hoenisch && .HYDROLOGY... The main thunderstorm concern for Tue through Thu will be the potential that some storms produce very heavy rainfall. Precipitable water is forecast to range from 1.50 to 2 inches. This would result in some storms producing very heavy rainfall in a short time. Thus much of the CWA is a marginal risk for flash flooding for later this week. Additionally, the heavy rainfall could cause additional impacts on burn scars, particularly the Horse Gulch burn area. Brusda && .PRELIMINARY POINT TEMPS/POPS...
