Morning observations show widespread precipitation greater than 0.1 inches, with pockets as high as 1-1.25 inches, has fallen over much of western SD and western NE in the last 72 hours. While some drier pockets remain, fuel guidance shows a notable decrease in dryness as a result. Meteorological conditions may still support some localized fire-weather concerns with strong southwesterly winds expected behind the surface low this afternoon. However, the strongest winds are likely to remain farther northwest where the heaviest precipitation has fallen. Gusty winds and humidity below 20% may support some drying today, but fuel recovery is expected to be modest such that no areas will be introduced. See the prior discussion for more information. ..Lyons.. 09/18/2024 .PREV DISCUSSION... /ISSUED 0154 AM CDT Wed Sep 18 2024/ ...Synopsis... A deep low-pressure system will move slowly east-northeastward over the northern High Plains through the period. On the backside of this system, a tight pressure gradient, and boundary-layer mixing into a belt of strong flow aloft, will yield strong post-frontal surface winds and 15-20 percent RH from eastern WY into the central Dakotas. While this would ordinarily support fire-weather concerns, precipitation over the past 24 hours should limit fuel receptiveness and the overall fire-weather threat. ...Please see www.spc.noaa.gov/fire for graphic product... $$
