906 FXUS65 KBYZ 071726 AFDBYZ Area Forecast Discussion...Updated National Weather Service Billings MT 1126 AM MDT Mon Jul 7 2025 .KEY MESSAGES... - Low precipitation chances linger through this afternoon, mainly over SE Montana. - Hot temperatures return with highs approaching triple digits in some locations Tuesday and Wednesday. - Cold front brings precipitation chances Thursday and Friday; along with more seasonal temperatures. && .DISCUSSION... Through Tuesday night... Canadian trof dropping southeast through Montana on the way into the northern plains will bring isolated showers and thunderstorms to mainly the eastern half of the forecast area through this afternoon. Best chances for precipitation will be counties along the eastern state line. Otherwise expect a good deal of sun today with season temperatures in the lower to middle 80s and a light easterly breeze. Ridging builds over the area for Tuesday for hot and dry conditions. Expect highs well into the 90s for most locations, with a few triple digits not out of the question. Those with outdoor plans and especially those that work outdoors should be prepared for the heat and take precautions to prevent heat related illness. Chambers Wednesday through Monday... Heat continues Wednesday with upper level ridging over the area. An approaching Pacific system will add some compressional warming to the mix boosting highs a few degrees over Tuesdays expected readings. Looking at a lot of upper 90s to over 100 degrees being advertised, with the hottest temperatures along the Yellowstone river from Billings to Miles City as well as across the Crow and Northern Cheyenne reservations. Current Heat Risk forecast is suggesting the need for a Heat Advisory for Wednesday from Yellowstone county east to Custer county. Will keep an eye on this and make a decision over the next couple of shifts. Once again, if you have outdoor activities planned, or work outdoors, be sure to take precautions to prevent heat illness during this period of heat. Aforementioned cold front looks to arrive a bit faster than previously forecast with winds turning northwesterly by sunrise Thursday. Forecast highs for Thursday are looking 10 to 15 degrees cooler than Wednesday with mainly mid 80s across the forecast area. Precipitation chances hold off until Thursday afternoon, but by Thursday evening 30 to 50 percent chances are widespread across the area. Precipitation looks to end Friday morning with a very pleasant afternoon on tap. Friday afternoon temperatures are forecast to be mainly in the upper 70s despite plenty of sun, along with a light northerly breeze. Looks like a great day to get outdoors, especially the mountain foothills that may stay in the 60s for afternoon highs. Hotter temperatures returns for next weekend, though there is increasing uncertainty regarding how warm during this period. The most recent models are starting to hint at a frontal boundary dropping in Saturday afternoon with northerly low level winds persisting through Sunday. NBM spreads for Max Temperatures for the weekend have widened due to this. So, take next weekend/early next week specifics with a grain of salt as we see how the models evolve with this potentially cooler and more unsettled pattern thats emerging. Chambers && .AVIATION... 18z Discussion... Widely isolated showers remain possible across far southeast Montana through 20z. Otherwise, VFR conditions will prevail across the region for the entire period. Winds will be light and variable across the forecast area with an occasional gust to 15kts out of the NE.
