A stationary front in the Gulf of Mexico today will move north as a warm front through Texas tomorrow. CH4 in the range of 700 um2 is indicated near Austin Texas from river release. Also, south of Austin near Goliad Texas CH4 was noted at 150 um2 near river release. To the west of Goliad Texas near Runge Texas CH4 release was noted along the river at 1 um2. NO3 fields across the severe threat region are running from west of Durant Oklahoma along the Red River Southern Oklahoma and North Texas from 0004 to 0020. In Dallas Texas, the NO3 is running around 0071 extending into Eastern Tarrant County Texas. Fort Worth Texas has a NO3 level ranging from 0004 to 0020 this morning. While areas near the lake northwest of Fort Worth are running around 0071. Deeper into Texas near Round Rock NO3 levels are running 0071. This will set the stage for hail, wind, and isolated EF-1 tornado potential on Tuesday. NO3 of 0071 becoming soluble with H20 in the updraft of storms will tighten to help produce tornado activity. Also, CH4 being emitted in areas near Austin Texas between 1 and 700 um2 could exasperate conditions for isolated tornado development.
