Issued at 1122 PM MDT Sun Mar 8 2026 A dry period, with above normal temperatures, is expected for the CWA much of this coming week. These parameters will produce elevated fire weather conditions over the plains early in the week, with critical fire weather conditions by Thursday and Friday as wind speeds are forecast to increase. Models indicate weak to moderate west-southwesterly flow aloft for the forecast area tonight through Monday. Weak upper troughing pushes across the CWA Tuesday with very little synoptic scale energy associated with it. By Tuesday night, strong northwesterly flow aloft moves into the CWA behind the trough and this continues into Thursday. Concerning moisture, there is a bit expected with and behind the weak trough, mainly on Tuesday afternoon into Tuesday night. There may be just enough on Tuesday evening for minor pops over the mountains and northern border plains. Otherwise, there is some mid and upper level moisture through the week, but nothing significant. For temperatures, thickness grids show Monday`s highs about 1-3 C warmer then today`s highs, so will go with lower and mid 70s for the plains. Tuesday`s readings cool down a slight bit, especially over the northeast corner where models are still showing weak cold front to move in. Models continue showing a more substantial cool down Tuesday night with a cold front associated with the weak passing trough moves across the area. Even with the cool down, Wedenesday`s highs over the plains will be a tad above seasonal normals with mid and upper 50s for the urban corridor. Thursday`s highs are progged to warm up substantially. For the later days, models continue to show northwesterly flow aloft over the CWA Friday into early next week. Models have a strong jet maximum moving in during the later half of the weekend along with pretty deep moisture. There is a cold front with upslope for the plains as well by later Sunday into Monday. Temperatures are well above normals Friday and Saturday, but cool down to just above normals Sunday and Monday. && .AVIATION /00Z TAFS through 00Z Tuesday/...
