ZCZC SPCFWDDY2 ALL FNUS22 KWNS 221827 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0127 PM CDT Mon Apr 22 2024 Valid 231200Z - 241200Z ...NO CRITICAL AREAS... The previous forecast (see below) remains unchanged. ..Squitieri.. 04/22/2024 .PREV DISCUSSION... /ISSUED 0156 AM CDT Mon Apr 22 2024/ ...Synopsis... Breezy/gusty post-frontal winds are expected across portions of the northern and central Plains on Tuesday. Over portions of southern NE and KS, these winds could briefly overlap 25-30 percent RH during the afternoon, given ample boundary-layer heating/drying. As a result, locally/briefly elevated fire-weather conditions are possible. Farther west, midlevel southwesterly flow will develop across the Southwest -- ahead of an approaching large-scale trough. While this will likely support an overlap of breezy surface winds and low RH across the region, fuels are generally not supportive of large-fire spread at this time.
U.S. Day 3-8 Fire Weather Outlook
ZCZC SPCFWDD38 ALL FNUS28 KWNS 222044 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0344 PM CDT Mon Apr 22 2024 Valid 241200Z - 301200Z A relatively active fire weather pattern is poised to set up across the southern High Plains late this week through this weekend. By Thursday, the first in a series of mid-level troughs will approach the southern Rockies, with surface low development likely across the central High Plains. By Thursday afternoon, a dryline will surge eastward across the southern High Plains, with Critically dry and windy conditions occurring behind the dryline. For Friday through the weekend, the approach/passage of another mid-level trough and associated surface cyclone will support continued eastward dryline surges over the southern High Plains, accompanied by Critically dry and windy conditions each afternoon. 70 percent Critical probabilities have been issued Days 4-6 (Thursday-Saturday) where Critical conditions should be most prolonged, and where fuels are most receptive to wildfire spread. Dry conditions should persist across the southern High Plains into early next week, though it is currently unclear if the surface winds will approach Critical thresholds. ..Squitieri.. 04/22/2024
