944 FNUS28 KWNS 052201 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0459 PM CDT Fri Jul 05 2024 Valid 071200Z - 131200Z ...Day 3/Sunday... A northwesterly midlevel speed maximum will overspread a hot/dry boundary layer over the Great Basin -- along the eastern periphery of a persistent large-scale ridge over CA. This will promote widespread elevated to locally critical fire-weather conditions across the eastern Great Basin. A focused area of critical conditions is evident over portions of southern/eastern UT, where strong northwesterly surface winds will overlap single-digit RH. 70-percent Critical probabilities have been added for this area (where fuels are most receptive). Moderate northwesterly flow aloft over the Pacific Northwest will also favor locally elevated fire-weather conditions in the Cascade Gaps, though critical conditions are not expected at this time. Farther south under the ridge, locally elevated conditions are expected across portions of Southern CA and the Central CA Coast, where continued hot/dry and locally breezy conditions are forecast. ...Days 4-8/Monday-Friday... The large-scale ridge will shift slowly southward/eastward, as low-amplitude troughing develops over the Pacific Northwest. This evolution will favor periods of breezy conditions across northern CA into the Northwest, where a hot/dry antecedent air mass will remain in place. Additionally, isolated thunderstorm potential will increase on Day 5/Tuesday through the remainder of the forecast period. As a result, fire-weather concerns will gradually increase, though the details are unclear at this time -- precluding Critical probabilities. ..Weinman.. 07/05/2024 ...Please see www.spc.noaa.gov/fire for graphic product... $$
