A cold front expected to move into north Texas on Thursday will likely stall somewhere close to the DFW Metroplex during the evening hours, then finally clear the area by Friday evening.

Also observe my somewhat informative graphic that I created, while not quite having the luxury of time to create it in. I hope it makes sense.

Above, I tried to demonstrate where and when the cold front will stall on Thursday and Friday. The area in orange represents my very rough approximation of areas where storms are possible Thursday, while the green area represents highest likelihood of storms Friday. Both days, DFW is covered in my shaded area.

The environment before the front Thursday afternoon will be rich with moisture, so 2,000 J/kg of CAPE may be available for these storms to work with. Minimal wind shearing will exist without the support of the upper level trough, which will be lagged well behind the front. This means strong to maybe borderline severe storms are possible stacked up along and perhaps just infront of this front Thursday afternoon and evening, but no well organized severe storms are expected.

Friday may be more wide spread general rainfall and storms, possibly coming to an end Friday evening when the front exits the region finally.

Temps behind the front this weekend will be similar to last weekend, highs in the low to mid 80s, and lows near 60.
