349 FNUS22 KWNS 151945 FWDDY2 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0244 PM CDT Wed Oct 15 2025 Valid 161200Z - 171200Z ...NO CRITICAL AREAS... No changes to the Day 2 Outlook, see previous forecast. ...Colorado High Plains... A mid-level jet ahead of a pronounced mid-level trough across the West will overspread the central/northern Plains Thursday. An associated lee cyclone/trough in eastern CO along with enhanced mid-level southwest flow aloft over the central Rockies should support a favorable downslope warming/drying event across eastern Colorado Thursday. Locally elevated fire weather conditions with west/southwest winds of 15-20 mph and relative humidity falling to as low as 10% are expected, aligning with pockets of drier fuels that remain after showers/thunderstorms from the day 1 period. ..Williams.. 10/15/2025 .PREV DISCUSSION... /ISSUED 0146 AM CDT Wed Oct 15 2025/ ...Synopsis... Downstream of a highly amplified large-scale trough over the West, a south-southwesterly midlevel jet will overspread the central/northern Plains. A related surface low will track northward across the northern Plains, while a secondary lee cyclone evolves over the central High Plains. Near and south of the lee cyclone, a tightened pressure gradient will favor 15-20 mph sustained southerly surface winds (with higher gusts) over the central/southern Plains. While these breezy/gusty winds may briefly overlap 25-30 percent RH over parts of the southern Plains (where fuels are dry), the fire-weather threat looks too marginal/localized for highlights at this time. Over parts of the Mid-Atlantic, dry/breezy post-frontal conditions may result in locally elevated fire-weather conditions for any areas that missed out on rainfall over the last couple weeks. ...Please see www.spc.noaa.gov/fire for graphic product... $$
