On Saturday, a mid-level shortwave trough is forecast to approach the northern California and Oregon coasts, with a fairly strong mid-level jet of 60-70 kts forecast to move northward from the San Francisco Bay area into southeastern Oregon. This trough and associated jet streak will bring critical fire-weather conditions across portions of southeastern Oregon and northern Nevada, as well as southwestern Nevada and the White/Inyo mountains of California. ...Dry/Windy... Two primary areas for critical fire-weather conditions are anticipated -- one over portions of northern Nevada and southern Oregon, and the other over southwestern Nevada and the White/Inyo mountain ranges of California. The strongest winds will likely be beneath the strongest flow of the mid-level jet streak and near the surface low in Oregon, forecast to be as high as 20-25 MPH with gusts up to 35 MPH possible. These winds will overlap with relative humidity values of 10-15% and ERC fuels near the 90th annual percentile. Some recent wetting rainfall has occurred over south-central Oregon, though modestly dry/windy conditions on Friday should result in at least some drying of fuels before Saturday. In southwestern Nevada and portions of the White/Inyo mountains in California, sustained winds of 20-25 MPH and relative humidity values of 10-15% will overspread fuels at or exceeding the 95th annual percentile, resulting in critical fire-weather conditions. Modifications to these areas may be needed with updated fuels and meteorological guidance. ..Halbert/Squitieri.. 08/16/2024 ...Please see www.spc.noaa.gov/fire for graphic product... $$
