Across southwest TX, elevated to locally critical fire weather conditions remain likely by early afternoon. The 12 UTC Midland, TX sounding sampled a very dry residual boundary layer atop a shallow nocturnal inversion.

Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0251 AM CST Fri Dec 08 2023 Valid 111200Z - 161200Z ...DISCUSSION... Severe potential appears likely to be negligible for several days in the wake of this weekend's cold front progressing through much of the Gulf. Above-average agreement exists with the establishment of a surface anticyclone over the East on D4/Monday, further reinforced later in the week. This will yield predominant easterly surface winds by D5/Tuesday over the Gulf and FL Peninsula, with gradual airmass modification through the rest of the period. Curiously, both the deterministic 00Z GFS and ECMWF to varying …

SPC Day 2 Fire Weather Outlook Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1154 PM CST Thu Dec 07 2023 Valid 091200Z - 101200Z ...Synopsis... The upper-level trough will move through the southern Plains and towards the lower Mississippi Valley, amplifying as it progresses. At the surface, a cold front will continue to the east through the Plains. Dry, gusty conditions are likely for at least parts of the southern High Plains into the Rio Grande Valley. RH may end up more marginal on Saturday compared to Friday due to the cold advection. Values near 20% appear possible for the Trans-Pecos into the adjacent Rio Grande Valley. Winds of 15…

SPC Day 1 Fire Weather Outlook Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1153 PM CST Thu Dec 07 2023 Valid 081200Z - 091200Z ...Synopsis... An upper-level trough will be in the process of intensifying and digging southeastward today. A surface low will deepen in western Oklahoma during the morning and into the afternoon. Ahead of a cold front, westerly surface winds will intensify from the South Plains into the Trans Pecos. Winds of 15-20 mph (locally to 25 mph) and RH of 15-20% will develop in this downslope regime. Given at least marginally dry fuels, elevated to locally critical fire weather is possible. Behind the upper trough,…

SPC Day 3-8 Fire Weather Outlook Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0336 PM CST Thu Dec 07 2023 Valid 091200Z - 151200Z Dry and breezy north-northwesterly flow is expected across portions of the Southern High Plains on Saturday. However, temperatures are expected to be cool, and fuels only marginally dry. Therefore, no critical probabilities are warranted. Sunday and beyond, a relatively benign fire weather pattern is expected. A few periods of weak lee troughing and some increase in southerly flow across the High Plains, but nothing appears strong enough to warrant probabilities. Elsewhere, cold conditions or most fuels pre…
