...17z Update... No changes, dry post-frontal conditions are likely across parts of eastern Montana and the western Dakotas this afternoon. Fuels farther south are not overly receptive, but surface wind gusts of 25-30 mph with RH near 20-25% will support several hours of elevated fire-weather potential. See the previous discussion for more info.

...Synopsis... A mid-level trough will deepen across the central and eastern CONUS as a mid-level ridge builds over the western U.S. today. Rich low-level moisture will overspread most of the CONUS east of the Rockies, with scattered to widespread thunderstorms expected, mitigating significant wildfire-spread concerns over most locales. The one exception will be over parts of the northern High Plains. Widespread 15-25 mph sustained northwesterly surface winds are likely in a post-cold frontal regime, where RH may dip into the 15-25 percent range. Given modestly dry fine fuels present, Elevated highlights have been maintained.
Elsewhere across the Desert Southwest into the Great Basin, a dry and mixed boundary layer should support widespread lower RH. However, the lack of a stronger surface wind field suggests that fire weather highlights are not currently warranted.
