Isolated dry thunderstorms are anticipated across portions of southern Idaho into southwestern Montana as an upper-level trough continues to progress eastward across the Northwest. Additionally, elevated fire-weather conditions are expected across the southern Cascades, portions of northern Montana, and the northern Great Plains. ...Pacific Northwest... As an upper-level trough is forecast to continue progressing eastward out of the Pacific Northwest and into Montana on Thursday, isolated dry thunderstorms are expected across much of the region over receptive fuels. While thunderstorm coverage could approach scattered criteria, current forecast guidance suggests a mix of both wet and dry thunderstorms, in addition to at least some minor potential for some wetting rainfall from the previous day's weather. This uncertainty currently precludes the expansion of the isolated dry thunder area and the inclusion of any scattered dry thunder areas, though forecast trends will continue to be monitored for subsequent updates. Elevated fire-weather conditions are expected to occur over the southern Cascades, especially where local gap flow enhanced winds could contribute to wildfire spread with existing fires. Current forecast guidance suggests that there is less potential for winds to reach elevated criteria over the northern Cascades as the upper-trough begins to leave the region, resulting in the removal of the area from the previous forecast. Some elevated fire weather conditions are also possible in portions of north-central Montana, but the overlap of stronger surface winds and receptive fuels is somewhat narrow. ...Northern Great Plains... Elevated fire-weather conditions are anticipated, particularly along portions of western Montana and Wyoming, into eastern Nebraska and the Dakotas. Strong southerly flow, coupled with hot, dry boundary layer profiles, are expected to persist for much of the afternoon and into the evening. However, current fuel guidance leaves some uncertainty on where these conditions have significant overlap with receptive fuels, particularly with eastward extent. ...Please see www.spc.noaa.gov/fire for graphic product...
