NWS Great Falls, MT wrote its last area forecast discussion before the first event at Jun 13, 10:55 PM MST, 3 hours 34 minutes earlier.
Area Forecast Discussion National Weather Service Great Falls MT 1155 PM MDT Mon Jun 13 2022 UPDATED AVIATION SECTION .SYNOPSIS... A slow moving weather system will affect much of North Central and Southwest MT through Wednesday with a mix of precipitation and thunderstorms. Snow, heavy at times, is expected over the Rocky Mountain Front and across the mountains of Central MT through Wednesday. Thunderstorms will affect Southwest MT over the next few days. Additionally, below normal temperatures early this week will rise well above normal for Friday. && .UPDATE... Updated forecast is out this evening. Main adjustment was to freshen Pops this evening. Temperatures are below freezing over the Rocky Mountain Front in the mountains, so as precipitation develops, it should be mostly snow for elevations above 5000/6000 feet. The snow will develop over Central MT after Midnight, thus no changes to the winter highlights. For the QPF for Tuesday, the downslope winds could limit some of the forecast QPF over the Plains, so some adjustments to the current QPF forecast for Tuesday are possible overnight. The wind forecast looks on track, no changes. Do expect some wind impacts on Tuesday, especially since trees have fully leafed out. All flood highlights look on track from this afternoon, with no changes. Note, the latest river forecasts crests on the Gallatin/Missouri have gone down a touch, which is good news. Brusda && .AVIATION... 1155 PM MDT Mon Jun 13 2022 (14/06Z TAF period) A low pressure system will move slowly east along the Canadian border over the next 24 hours, driving the weather across North Central, Central, and Southwest Montana. Overall, though, mostly VFR conditions are expected, unless otherwise mentioned. A disturbance will bring showers, possibly with periods of MVFR conditions, to Southwest Montana through around 15Z, but showers will linger through at least 00Z around KWYS. Otherwise, the low pressure system will spread strong gusty westerly winds with periods of rain and mountain snow over the area from the northwest through 18Z. This should cause occasional mountain obscuration in periods of MVFR conditions, mountain wave turbulence, and low level wind shear. -Coulston Refer to weather.gov/zlc for more detailed regional aviation weather and hazard information. && .PREV DISCUSSION... /ISSUED 605 PM MDT Mon Jun 13 2022/ Today through Friday... The main concerns for the next few days will be broken down by topic. Winter Weather...No changes to current winter highlights. Snow, heavy at times, is expected to develop over the Rocky Mountain Front and across Central MT tonight, then last into Wednesday. There will be a sharp cut off in snow as you go down in elevation, and out over the Plains, where strong downslope winds will occur. Since some of the snowfall will occur during the day on Tuesday, some melting will occur, making total snow accumulation totals a bit difficult Never the less, the previous snowfall forecasts are generally on track, with a general 4 to 8 inches around pass level and 12 to 20+ inches at ridge tops. High Winds...Only change, added Fergus County to the high wind watch for Wednesday. The other wind highlights remain the same. As the upper level low develops over North Central MT, strong downslope winds will also develop over North Central MT. The strong winds could develop as early as early Tuesday morning over the western portions of North Central MT, and then will gradually spread out over the Plains on Tuesday. There is still a reasonable probability for strong winds on Wednesday over the eastern portions of the CWA, thus the high wind watch continues for that area. Impacts from the wind could result in higher tree damage with this event, as trees have fully leafed out. Temperatures...well below normal temperatures are expected for Tuesday for most areas, then some warming will occur Wed/Thur. By Friday...afternoon highs could be close to 20 degrees above normal, with a few record highs possible. Fog...Areas of fog area possible at times through Thursday morning, especially in the higher elevations. Friday night through Monday...A moist southwesterly flow aloft will set up over MT. With upper level disturbances moving northward through the region, expect periods of showers and thunderstorms. With the airmass becoming fairly unstable at times, some strong/severe storms will be possible this weekend into early next week. Some storms could also produce heavy rainfall.
