043 FNUS22 KWNS 011939 FWDDY2 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0238 PM CDT Mon Jul 01 2024 Valid 021200Z - 031200Z ...Northern CA... Confidence has increased that gusty northerly winds will likely develop over parts of the northern Sacramento Valley late D1/Monday night and continue through D2/Tuesday beneath a strong ridge of high pressure. Extreme heat is also expected to support low humidity among rapidly drying fuels. An Elevated area has been introduced for the northern Sacramento Valley and adjacent foothills to cover near-critical fire-weather potential. ...Southern Plains... Extremely warm temperatures are expected to overlap with areas of dry southerly return flow over parts of western OK and the TX Panhandle D2/Tuesday. Afternoon highs over 100 F will allow for diurnal RH minimums of 25-30% colocated with southerly wind gusts in the 15-20 mph range. Ongoing flash drought has exacerbated area fuel concerns and elevated fire-weather conditions are possible. ...Cascades and Columbia Basin... Dry northwesterly flow is expected to overspread the Cascade and western Columbia Basin ahead of the rapidly building ridge. Stronger gusts are possible through the Columbia Gorge and Cascade Gaps, as a weak upper trough moves around the eastern side of the ridge tomorrow afternoon. While fuels are not overly supportive currently, rapid drying and occasional gusts of 15-20 mph near the terrain may support locally elevated fire-weather concerns for a few hours. ..Lyons.. 07/01/2024 .PREV DISCUSSION... /ISSUED 0153 AM CDT Mon Jul 01 2024/ ...Synopsis... The mid-level trough responsible for fire weather conditions over the Great Basin today will eject into the Plains states tomorrow (Tuesday). Nonetheless, broad cyclonic mid-level flow will prevail over the Interior West for the Day 2 period. Furthermore, a mid-level jet streak will also approach from the northwest and overspread the Pacific Northwest during the later part of Day 2. Dry downslope flow is likely over the lee of the Cascade Ranges into the Harney Basin in Oregon, as well as the Columbia Basin in eastern Washington. Latest high-resolution guidance consensus depicts Elevated-equivalent conditions constrained to mainly the higher terrain. When also considering modest fuel receptiveness, fire weather highlights have been withheld this outlook. However, Elevated highlights may be needed in future outlooks if Elevated dry and windy conditions become more prevalent in later guidance. ...Please see www.spc.noaa.gov/fire for graphic product... $$
