In the mid levels, a broad southern-stream shortwave trough is
forecast to merge with a second northern-stream trough over the
Great Lakes. Deepening into a large upper low, the broad area of
cyclonic flow will dominate the eastern half of the CONUS by 12z
Saturday. At the same time, weak ridging should develop in the wake
of the trough across portions of the western CONUS. Increasingly
strong northwesterly flow aloft will help drive windy conditions at
the surface within a post-frontal airmass across much of the central
and southern Plains. While breezy, much cooler surface temperatures
and higher relative humidity should keep the threat for sustained
fire-weather conditions relatively low across the central CONUS.
