This trough will become neutrally tilted across the eastern CONUS before eventually becoming negatively tilted across the Northeast. In the wake of this mid-level trough, a strong cold front will bring a continental polar airmass across much of the United States. ...Day 3/Fri Southwest into Far West Texas... Dry and windy conditions are expected across southern New Mexico and Far West Texas on Friday. A weak lee cyclone may lead to some tightening pressure gradient. However, strong winds will primarily be driven by a moderate to strong mid-level jet overspreading a deeply mixed airmass with stronger winds reaching the surface. In addition, 10 to 15F above normal temperatures will lead to relative humidity in the teens and further support some fire weather threat. ERC values remain near seasonable normals, but dormant, fine fuels continue to cure and may support some fire spread and an increase in initial attack. Some dry and breezy conditions are also possible on Day4/Sat in portions of the TX/OK Panhandle and vicinity. However, these conditions are expected in the post-frontal airmass where temperatures will be cool and therefore, fire weather concerns should be reduced. A weak mid-level shortwave trough embedded in the northwesterly flow across the Central Rockies may result in some weak cyclogenesis on Sunday across the central Plains. This may cause some dry and breezy conditions across the southern High Plains. However, confidence in stronger wind speeds is not high enough to necessitate probabilities at this time. ..Bentley.. 12/06/2023 ...Please see www.spc.noaa.gov/fire for graphic product...
