Existing Elevated highlights across portions of NV were shifted slightly to the northwest and northeast. Increasing mid-level south-southwesterly flow will overspread the Great Basin this afternoon as an amplifying upper trough enters the northern CA coast. Observed wind gusts already near 30 mph from the south-southwest have occurred in higher elevations across central and eastern Nevada this morning. Daytime boundary layer heating/mixing should manifest in accelerating south-southwest winds across central/northeastern NV to between 15-20 mph by this afternoon. Current relative humidity in central NV valleys already in the 20-25% range will fall close to 10% in some locations by peak heating. These dry and breezy conditions will lead to an Elevated fire weather threat across central and northeastern NV this afternoon where receptive fuels exist. ..Williams.. 09/27/2026 .PREV DISCUSSION... /ISSUED 0142 AM CDT Sun Sep 27 2026/ ...Synopsis...

Afternoon boundary-layer mixing will yield sustained south-southwesterly surface winds of 15-20 mph (with higher gusts) amid 10-15 percent RH. These dry/breezy conditions, combined with sufficiently receptive fuels, will lead to elevated fire-weather conditions across portions of central/eastern NV. ...Please see www.spc.noaa.gov/fire for graphic product... $$
