834 FNUS28 KWNS 182132 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0430 PM CDT Wed Sep 18 2024 Valid 201200Z - 261200Z An active mid-level flow regime is expected across the CONUS over the next seven days. Troughing over the western US will gradually move eastward as an embedded speed max passes over the Southern Rockies/Plains this weekend with gusty winds and dry conditions. By early next week, troughing will move over the central CONUS favoring cooler and wetter conditions. At the same time, ridging should redevelop to the west. Some potential for easterly offshore winds could develop over parts of CA and OR early next week, but significant forecast uncertainty is present in the medium range. This suggests the threat for fire-weather conditions is relatively low. ...Southern Plains... As troughing gradually moves eastward, stronger southwesterly flow aloft will overspread parts of the Southern Rockies/Plains late this week and into the first half of the weekend. A lee low will quickly deepen over eastern CO supporting periods of gusty downlope winds, with gusts of 25-30 mph. However, moisture return ahead of the low will favor higher RH values. Additionally, recent precipitation has likely tempered fuels somewhat, with more precipitation likely in into this weekend. Thus, while some risk for fire-weather conditions may develop over the Plains, confidence is low. ..Lyons.. 09/18/2024 ...Please see www.spc.noaa.gov/fire for graphic product... $$
