FNUS22 KWNS 150555 FWDDY2 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1255 AM CDT Wed Apr 15 2026 Valid 161200Z - 171200Z ...Synopsis... An upper-level trough will dig into the southern Great Basin/Four Corners on Thursday. A modest subtropical jet stream will develop across northern Mexico into the southern Plains. At the surface, a strong low pressure system will deepen in the vicinity of the Black Hills. A fairly strong cold front will progress southward into the central Plains. ...Southern New Mexico into central High Plains... This region will generally exist in between the developing southern stream jet and the digging trough to the northwest for most of the period. Some increase in mid-level winds may occur by late afternoon, however. A very dry airmass is expected. RH could approach single digits locally, but will more broadly be 10-20%. This is forecast despite increasing mid/upper clouds with time. The overall expectation is for elevated to near critical fire weather conditions. Sustained critical could occur locally, but confidence highlighting where this will occur remains low. ...Far eastern Wyoming into Nebraska/South Dakota... As the surface low deepens, winds of 15-20 mph will be possible. RH values of 10-20% will occur during the afternoon. The strongest mid-level flow will generally remain farther west of the region which should limit the potential for sustained critical conditions. Further, the cold front is forecast to progress southward which will lead to a stark shift to northerly winds and greater RH. Given the strength of the front, the more southern frontal solutions have been weighted higher in this forecast. ...Southern Appalachians into Mid-Atlantic... The persistent dry return flow pattern will continue another day. Temperatures in the mid 80s to low 90s F will again promote a broad area of reduced RH values during the afternoon. 25-35% will again be common, but areas near 20% are still possible. Winds will still be somewhat weak at 10-15 mph, but very dry fuels will still support a elevated fire weather threat. ..Wendt.. 04/15/2026 ...Please see www.spc.noaa.gov/fire for graphic product... $$
