SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0330 PM CST Sat Feb 01 2025 Valid 031200Z - 091200Z An elongated upper-level ridge will begin to amplify early next week as a trough moves into the West. Model trends over the past 24 hours have generally decreased the amplitude of the western trough. This is most notable in the GFS. This impacts the southern extent of the stronger mid-level flow and, consequently, the strength of the lee trough anticipated towards next Wednesday. Of further note, the shortwave trough feature in the southern High Plains on Wednesday has sped up in the latest model guidance and is slightly less optimally timed during the afternoon as a result. At the surface, an initial cold air surge on Monday/Tuesday in the Plains will likely stall somewhere in Oklahoma and will not make much westward progress into the southern Rockies. Another cold air surge will push farther south and west on Thursday. ...Southern High Plains... A few days of at least modestly dry and breezy conditions are expected this weekend into early next week. Fuels will continue to dry further given the lack of precipitation recently. Given the model trends of late, confidence in critical fire weather remains low to moderate. Based on the ECMWF as well as ensemble guidance, 40% critical probabilities will be maintained as the pattern will still support elevated to locally critical fire weather. Of course, model trends will continue to be monitored over the next few days. ..Wendt.. 02/01/2025 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0102 PM CST Sat Feb 01 2025 Valid 031200Z - 041200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected across the U.S. on Monday. ...Synopsis... A mostly zonal flow regime will exist during the day on Monday, with some gradual height falls occurring late across the West and over the Northeast. A large area of high pressure over the Southeast will prevent appreciable destabilization over land, although limited/shallow moisture return will occur over TX with southerly surface winds. Elsewhere, a midlevel moist plume will result in precipitation across northern and central CA, but poor lapse rates will likely limit even elevated convective potential. ..Jewell.. 02/01/2025 Read more

Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0101 PM CST Sat Feb 01 2025 Valid 021200Z - 031200Z ...NO CRITICAL AREAS... No changes to the ongoing forecast. ..Wendt.. 02/01/2025 .PREV DISCUSSION... /ISSUED 0200 AM CST Sat Feb 01 2025/ ...Synopsis... Flow aloft will be primarily zonal over the central US through the weekend. In response, lee troughing will persist with west/southwesterly winds over much of the southern Plains. Some fire-weather risk is possible as area fuels dry with warm temperatures and low humidity. However, the overlap of strong winds and low humidity is not expected to support widespread critical concerns. ...Southern High Plains... At least modestly dry and windy conditions should continue into D2/Sunday as the lee low/trough remains over the High Plains. Continued warm and dry conditions will support further drying of area fuels. While zonal flow aloft is expected to be fairly strong, it is displaced to the north. This should keep surface wind speeds modest for much of that period across areas of the drier/more receptive fuels. Localized elevated fire-weather conditions are still possible from southeastern NM into West TX. However, conditions are not expected to be widespread enough to support an Elevated area. ...Please see www.spc.noaa.gov/fire for graphic product... Read more
