105 FNUS22 KWNS 251909 FWDDY2 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0208 PM CDT Tue Jun 25 2024 Valid 261200Z - 271200Z An isolated dry-thunderstorm risk area has been introduced to parts of northwest NV into far southeast OR. Isolated showers and thunderstorms may be ongoing across the region by 12 UTC Wednesday. While a weak lightning signal is noted in recent CAM guidance, a subtle QPF signal coupled with weak buoyancy, fast storm motions, and dry conditions between 0-2 km suggests a few dry lightning strikes are likely with any thunderstorm that can develop. Given antecedent dry fuels, dry lightning starts appear possible. Elevated to locally critical fire weather conditions remain probable across northwest NV/southeast OR in the wake of early-morning convection as described in the previous discussion below. ..Moore.. 06/25/2024 .PREV DISCUSSION... /ISSUED 0211 AM CDT Tue Jun 25 2024/ ...Synopsis... A deepening surface pressure low near the ID/OR border is expected to accompany a mid to upper-level Pacific trough moving onshore Wednesday. The associated pressure gradient will tighten over the Pacific states (in particular across western OR) yielding breezy west to southwest surface winds ahead of an approaching cold front. Some initial cloud cover early in the day may briefly inhibit mixing, but clearer skies during the afternoon should allow for momentum transfer of stronger flow from aloft aiding in higher wind gusts. In addition, RH will drop into the low teens within this more deeply mixed air mass ahead of the front, across portions of the western and northwestern Great Basin. A few hours of elevated conditions are expected here. ...Please see www.spc.noaa.gov/fire for graphic product... $$
