Issued at 249 PM CDT Sun Jul 12 2026 An upper level ridge continues to dominate the upper level pattern across the Plains and the Rockies. This has brought widespread hot temperatures into the Northern Plains. The low level thermal ridge is centered across eastern Montana. This will cause temperatures to warm across western North Dakota to around 106 to 109 degrees this afternoon with the central and northern half of the state seeing 100 to 105. The central and eastern half of the state has dew points in the 60s to lower 70s leading to heat index values of 105 to 110. There is also a high chance of breaking record high temperature for Bismarck, Dickinson, Williston, and Minot for today and tomorrow. Tonight low temperatures are forecast to drop down around 70s potentially breaking record high low temperatures for the same locations. Hot temperatures will continue into the start of the week. The low level thermal ridge will slide eastward as the upper high centers over the Northern Plains. High temperatures Monday are forecast to be around 100 to 105 with the hottest spots being the southwest and the south central. A cold front is forecast to sag across the northwest leading to high temperatures in the 90s for Crosby. The upper level ridge will dampen this week across the Canadian Prairies. This will lead to multiple waves traversing across southern Saskatchewan and Manitoba. There are low chances of showers and thunderstorms by the middle of the week into the weekend across the northern half of the state. The upper level ridge will persist across the the Plains through the weekend. 100 degree temperatures are forecast across the southern half of the state through the middle of the week. After that, above normal in the upper 80s to upper 90s are forecast to persist into the weekend. && .AVIATION /06Z TAFS THROUGH 06Z TUESDAY/... Issued at 1157 PM CDT Sun Jul 12 2026 VFR conditions are expected through the 06Z TAF period. LLWS across the areas through around 12 UTC, then mainly a moderate to strong southerly flow through the day Monday. The exception being the far northwest (including KXWA) where a northerly flow will remain behind a near stationary cold front.
