608 FNUS21 KWNS 301651 FWDDY1 Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1150 AM CDT Sun Jun 30 2024 Valid 301700Z - 011200Z ...CRITICAL FIRE WEATHER AREA FOR PARTS OF EASTERN NV AND WESTERN UT... ...17z Update... The ISODRYT area was adjusted south and east for the latest hi-res guidance. Isolated storms should develop late this afternoon with little to no wetting rainfall over far northeast CA, southeast OR and northern NV. A very isolated storm will remain possible over the southern Cascades, though coverage is too limited for higher thunder probabilities. Weak CAPE should support intermittent cloud to ground lightning and the potential for ignitions through this evening. Otherwise, minimal changes were made to the current outlook. Critically dry and windy conditions are expected this afternoon over the eastern Great Basin. See the previous discussion for more information. ..Lyons.. 06/30/2024 .PREV DISCUSSION... /ISSUED 0157 AM CDT Sun Jun 30 2024/ ...Synopsis... An upper ridge will remain in place over the central CONUS as a mid-level trough traverses the Interior west today. A surface cyclone will become established across the Great Basin, with dry and breezy conditions expected ahead of an approaching cold front during the afternoon. Widespread 20+ mph sustained southwesterly surface winds will coincide with 5-15 percent RH for much of the Great Basin into the central Rockies. Critical highlights have been maintained where these surface conditions will overlap with fuels that are most favorable for supporting wildfire-spread potential. Meanwhile, thunderstorms are expected to form immediately ahead of the cold front across portions of the Pacific Northwest. These storms are expected to be high-based since the boundary layer is expected to mix up to at least 600 mb. With fuels drying across the region, lightning strikes away from precipitation cores may support ignitions, warranting the maintenance of isolated dry thunderstorm highlights. ...Please see www.spc.noaa.gov/fire for graphic product... $$
