NIFC Predictive Services Weather Discussion:

Widespread showers and isolated thunderstorms will develop in much of the western and northern Great Basin today, with wetting rain across much of northern Nevada into central Idaho. Strong southerly winds of 20-35 mph with gusts 35-50 mph are likely from the Lower Colorado River Valley and Utah into much of the central High Plains. Relative humidity will be lowest in the Lower Colorado Valley, with higher humidity in much of Arizona, New Mexico, and West Slope where scattered showers and thunderstorms will develop.

 

In the East, a low off the Southeast coast will move closer to the coast, possibly moving onshore in North Carolina, with strong easterly winds and heavy rain likely for the eastern Carolinas and Virginia. Well above normal temperatures and dry conditions will continue for much of the Midwest, west slopes of the Appalachians, and Northeast. Downsloping easterly winds of 10-15 mph will continue in the Upper Ohio Valley and west slopes of the Appalachians, with minimum relative humidity as low as 10% creating locally elevated conditions. Scattered showers and thunderstorms are likely to develop in portions of the Lower Mississippi valley, as well.

​

Critical Fire Weather issued by the National Weather Service:

There are no Red Flag Warnings or Fire Weather Watches in effect. The Storm Prediction Center has identified two areas of Elevated Fire Weather for Nevada and along the Colorado|Kansas border.

Storm Prediction Center Synopsis:

...Synopsis...

Within the base of a deep midlevel cyclone moving eastward across the Great Basin, a related jet streak will overspread the Lower CO River Valley. Here, boundary-layer mixing into the strengthening flow aloft, coupled with a tightening pressure gradient peripheral to an evolving surface cyclone, will favor 20-25 mph sustained southerly surface winds. Despite a gradual increase in moisture/RH, diurnal heating should still support a corridor of around 20 percent RH amid the strong surface winds along the Lower CO River Valley -- favoring elevated fire-weather conditions. Elevated fire-weather conditions are also expected over portions of the central High Plains -- where breezy/gusty southerly surface winds will overlap 20 percent RH near a lee trough during the afternoon. While spotty rainfall during the past 24 hours could limit fuel receptiveness over parts of the area, mostly receptive fuels should still yield some fire-weather risk. Farther east, warm/dry conditions are expected over portions of OH and KY -- along the southwestern periphery of an expansive surface anticyclone. While sustained surface winds around 10 mph should limit the overall fire-weather threat, around 20 percent RH and very dry/receptive fuels will still pose localized fire-weather concerns during the afternoon. ..Weinman.. 09/16/2024
