Dry, post-frontal northerly flow is still expected to bring fire weather concerns into portions of central and southern TX on D2/Monday. Farther west, dry return flow on the western periphery of surface high pressure settling into the Plains will bring an Elevated fire weather threat to southeastern NM and far west TX. ...Southern and Central Texas... Stronger northerly flow will commence this evening across southern TX as a robust cold front quickly moves southward. Showers and thunderstorms are more likely to develop along the cold front near and east of the Houston metro area tonight into Monday morning, leaving much of southern TX dry. Sustained north winds of 15-25 mph and relative humidity between 15-25% by Monday afternoon are likely across portions of the middle and lower TX Coast areas where fuels remain very dry, including ongoing severe drought across far southern TX. These conditions necessitated introduction of Critical Highlights within a broader Elevated fire weather threat across central/southern TX. ...Eastern New Mexico into west Texas... Dry return flow on the western fringe of surface high pressure settling into the central U.S. will affect portions of southeastern NM and west TX Monday. A dry air mass will be in place across much of the southern High Plains in the wake of a cold front. South winds of 15-20 mph will develop and align with relative humidity of around 15% (despite considerably cooler temperatures) to bring an Elevated fire weather threat to east-central and southeastern NM as well as portions of western TX where dry fuels remain. ..Williams.. 03/15/2026 .PREV DISCUSSION... /ISSUED 1253 AM CDT Sun Mar 15 2026/ ...Synopsis... Post frontal northerly flow will shift into southern/central Texas for D2/Monday, with Elevated fire weather conditions expected. Dry return flow will bring Elevated fire weather concerns across eastern New Mexico into western Texas as a high builds across the southern Plains and moves into the lower Mississippi River Valley. ...Eastern New Mexico into west Texas... Across eastern New Mexico into western Texas, south to southeast winds 10-15 mph will overlap relative humidity reductions to around 15-20%. An Elevated was maintained with this outlook to support this threat. Fuels in this region are expected to be critically dry after multiple days of dry/wind conditions. ...Southern/Central Texas... Behind the southward advancing cold front, relative humidity reductions to around 15-25% (locally around 10% in south Texas) will overlap sustained north winds at 10-20 mph across portions of the south Texas Brush Country to the Rio Grande Valley and across the Middle Texas Coast. The D3 40 percent was maintained and expanded across the coast with this update. Fuels across the south Texas Brush Country are critically dry, with ERCs forecast to be around the 75-90th percentile. Fuels across the middle Texas coast region are more marginal but are forecast to be around the 50-75th percentile by D2/Monday. ...Please see www.spc.noaa.gov/fire for graphic product... $$
