Area Forecast Discussion...UPDATED National Weather Service GLASGOW MT 932 AM MDT SUN JUL 10 2016 .SHORT TERM...for northeast Montana...today through Tue... ...Severe weather is expected across much of northeast Montana late this afternoon and evening with large hail, damaging winds, and heavy rainfall the primary threats... Sent an update this morning to provide more detail with the latest near and short term model updates and consensus. Current rain showers and thunderstorms are expected to increase in coverage and intensity through the day. Strong to severe thunderstorms should develop and move through the area later this afternoon and evening, although the favored area for the best chances of this may only be near and south of the Yellowstone River valley due to an extensive cloud cover everywhere else. Convective inhibition looks to keep a cap on severe thunderstorm development for most other locations. Latest SSEO guidance from SPC brings some severe thunderstorms through the Miles City, Glendive, and Wibaux areas this afternoon and evening. Other strong thunderstorms will spread through the remainder of northeast Montana today and tonight. BMickelson Previous short term discussion: Isolated to widely scattered showers continue across northeast Montana very early this morning as evident on radar imagery. The large upper trough and closed low will continue to drive dynamic support for severe weather late in the day and this evening with diffluent upper level southwest flow. Bufkit forecast soundings show the presence of plenty of instability and 40 to 50 kts of 0-6 km shear. Precipitable water values will range between 1 and 2 inches in many areas. Thus, large hail, damaging winds, and heavy rainfall are especially possibilities with this activity. SPC SSEO maximum updrafts were followed closely for timing and placement of severe wording in weather grids. The large upper level trough will continue to influence the weather conditions across the region into MOnday and Tuesday with showers and thunderstorms continuing at times. All told rainfall totals of one to two inches seem pretty reasonable for many areas in northeast Montana. Maliawco .LONG TERM...Tue night through Sun... Weather pattern midweek will feature an upper low moving into western Ontario and another taking shape in the Gulf of Alaska. This will result in nearly zonal flow across Montana which shift to northwest through the end of the week as slight ridging develops over the northern Rockies. No strong system indicated in the models but enough moisture and instability in the flow for the potential for a few thunderstorms most days, with best chances near the Canadian border. With the northwest flow temperatures will be slightly below normal for the period. Models trending toward more agreement with the Gulf of Alaska low dropping into the Pacific Northwest by the weekend. This will turn the upper flow back to the southwest increasing the potential for stronger thunderstorms. Ebert && .AVIATION... Flight category: Mainly VFR. Synopsis: Showers and thunderstorms will be moving across the region through the period and may produce brief gusty winds and lower visibility. Severe thunderstorms: There is a threat for severe thunderstorms between 21Z and 03Z today, with KSDY and KGDV seeing the largest threat for severe hail and winds. An overall wet pattern will continue into Tuesday. Winds: Generally northwest 5-15kts. Gilchrist && .GLASGOW WATCHES/WARNINGS/ADVISORIES...NONE. && weather.gov/glasgow
