Area Forecast Discussion National Weather Service Glasgow MT 253 PM MDT Wed May 24 2023 .DISCUSSION... Afternoon Discussion: Today through tonight: The air mass over the area continues to destabilize, and some isolated locations already have storms beginning to fire. A north- south oriented surface boundary over Phillips and eastern Petroleum counties will continue to move eastward, so storm coverage will increase into the early evening hours relative to this boundary. SB CAPE values are between 1000 and 2000 J/kg and bulk shear from 0 to 6 km is between 20 and 25 knots. The low wind shear and PWAT values from 1 to 1.2, isolated areas of flash flooding are possible today, especially with and slow-moving or training storms. There is moderate confidence (50 percent) that some storms will produce severe hail and wind (hail 1 inch in diameter or greater, and winds gusting 58 mph or more). Thursday and Friday: Each afternoon, there is moderate confidence (50 percent) of thunderstorms occurring in northeast MT. Storm coverage is likely to cover locations along the ND/MT border on Thursday afternoon, and coverage is likely to occur further west, possibly as far west as Phillips and Petroleum county. Small hail, heavy rain, strong wind gusts, and lightning are likely with any of the storms that occur. Saturday onward: There is low confidence (30 percent) in the severity of thunderstorms occurring this weekend. However, rain showers appear likely through Saturday night based on the NBM guidance, with a lower probability of precipitation afterward. There is a hint of this stormy pattern being replaced by a ridge by Tuesday, but uncertainty is still high with this scenario. -Stoinskers && .AVIATION... LAST UPDATE: 2100Z FLIGHT CAT: VFR. Temp MVFR Possible. DISCUSSION: Isolated to scattered thunderstorms and convection will move north through NE Montana today and tonight. KGGW and KOLF are likely to be affected by thunderstorms, and KGDV and KSDY are less likely to occur this evening. Erratic and gusty winds will be the biggest impact. Bulk of the forecast is VFR. Terminals that receive a direct hit from a thunderstorm, especially this afternoon, may drop to MVFR visibility very briefly due to moderate rain (RA). WIND: Southeast at 10 to 20 kts through the day, becoming light and variable after sundown. On Thursday, northwest winds 5 to 10 for KGGW. West winds 5 to 10 for KOLF. Southwest winds 5 to 10 knots for KSDY and KGDV. -Stoinskers && .GLASGOW WATCHES/WARNINGS/ADVISORIES...NONE. && weather.gov/glasgow
