Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0222 PM CDT Sun Jun 30 2024 Valid 011200Z - 021200Z ...20z Update... Minor changes have been made to adjust the Elevated area to better match greater fire-weather potential across portions of the northern and eastern Great Basin. Dry and breezy conditions are possible over a broad area within a post-frontal flow regime across NV. At least a few hours of 10-20% RH are likely to overlap with northwesterly gusts of 15-20 mph. The most likely corridors for sustained elevated to near-critical fire-weather conditions will be across portions of southern ID and eastern NV into southwest UT. Localized fire-weather conditions are also possible in northern CA. See the prior discussion. ..Lyons.. 06/30/2024 .PREV DISCUSSION... /ISSUED 0204 AM CDT Sun Jun 30 2024/ ...Synopsis... A mid-level trough will continue to progress eastward and impinge on the Rockies tomorrow (Monday) while upper ridging prevails across the central U.S. A mid-level jet streak will pivot around the trough and overspread the Great Basin region, supporting another day of dry and breezy conditions. By afternoon peak heating, much of the Great Basin will experience 15+ mph sustained west-southwesterly surface winds amid 10-15 percent RH, warranting the introduction of Elevated highlights. Dry conditions (i.e. RH as low as 10 percent in spots) are also expected across much of the California Central Valley region, where fuels are becoming increasingly receptive to wildfire spread. At the moment, the consensus among model guidance members suggests that surface winds will be on the lighter side, with fire weather highlights withheld for now. However, at least Elevated highlights may be needed in future outlooks if guidance trends windier in California. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

A mid-level trough will continue to progress eastward and impinge on the Rockies tomorrow (Monday) while upper ridging prevails across the central U.S. A mid-level jet streak will pivot around the trough and overspread the Great Basin region, supporting another day of dry and breezy conditions. By afternoon peak heating, much of the Great Basin will experience 15+ mph sustained west-southwesterly surface winds amid 10-15 percent RH, warranting the introduction of Elevated highlights. Dry conditions (i.e. RH as low as 10 percent in spots) are also expected across much of the California Central Valley region, where fuels are becoming increasingly receptive to wildfire spread.
