Dry air trailing that system will maintain low humidity and clear skies leading to diurnal temperature ranges of 25 to 30 degrees. These readings are about 5 degrees below average for the time of year. A strong upper level trough of low pressure will move across central Texas and into the Arklatex region Friday night into Saturday. A strengthening surface low pressure system and associated fronts will be draped across the Texas coastal area on Friday night before quickly translating to the northeast. With deep moisture moving in ahead of the system along with broad lift, showers will develop as the workweek ends. The low will reach I-20 by Saturday morning, pulling a cold front through the local area. Instability is expected to be too limited for severe weather, but some rumbles of thunder are possible as the front sweeps east. By Saturday afternoon, dry air to overtake the region behind that front, and moisture will be cut off, effectively ending the threat for organized precipitation.
