SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0126 AM CDT Fri Jun 28 2024 Valid 291200Z - 301200Z ...Synopsis... Upper ridging will build across the central Rockies into the Mississippi Valley tomorrow/Saturday as a mid-level trough impinges on the Interior West. A modest surface cyclone will develop over the Great Basin by afternoon, encouraging dry and windy conditions across portions of southern Nevada and surrounding areas. 15+ mph sustained southwesterly surface winds will overlap with 5-10 percent RH by afternoon peak heating over southern parts of the Great Basin. Some guidance suggests that wind speeds well over 20 mph may be observed over southern Nevada. However, marginally receptive fuels suggest that only Elevated highlights are warranted at this time. ..Squitieri.. 06/28/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0125 AM CDT Fri Jun 28 2024 Valid 281200Z - 291200Z ...NO CRITICAL AREAS... ...Synopsis... A mid-level trough will eject into the Northern Plains today as upper ridging builds over the Interior West. A surface cold front trailing the mid-level trough will sweep southward across the northern High Plains while monsoonal mid-level moisture meanders over the central Rockies into parts of the Desert Southwest. While elevated to critically dry and windy conditions will accompany the cold front across portions of southern Wyoming, fuels are too poorly receptive to support significant wildfire-spread potential. The thunderstorms supported by monsoonal moisture across the central Rockies into the Southwest should also be relatively slow moving, wet, and will traverse areas that have received rainfall in previous days. As such, lightning should occur over relatively moist fuels, limiting wildfire ignitions to a degree. ..Squitieri.. 06/28/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
