KATC StormTeam 3 Weather BLOG

After a simply gorgeous weekend our weather continues to transition to a warmer and more humid clime.  There will be a couple of weather features that Acadiana will be sandwiched between: a frontal trough in Eastern Texas, and a weak area of low pressure in the Southwestern Gulf of Mexico. The trough to the west is expected to slowly weaken while lifting to the northward over the next few days.  This trough has produced numerous showers and storms just to the west of Acadiana in Eastern Texas, with activity training into western and Central Louisiana and points to the northeast.  A trough over the western states will likely strengthen lifting this feature to the north while deeper tropical moisture surges from the Gulf over the next few days.  Meanwhile the low pressure system in the Gulf will drift northwestward through tomorrow and then northward early Wednesday making a turn to the east by late Wednesday.  We are not expecting any significant tropical development with this system but it should help to usher a decent slug of tropical moisture into the region for tomorrow and Wednesday.  It is not clear however on how much moisture we will see in Acadiana as this system will encounter upper westerlies that should drag the bulk of the deepest moisture just to our east.  Nonetheless we’ll go with a few showers overnight and tomorrow with a better chance of scattered showers and storms on Wednesday.  Lingering showers will be possible again early Thursday until slightly drier more subsident air arrives for late Thursday.  Summer-like temperatures will stay with us through the weekend with highs in the upper 80s while lows stay closer to 70.  A significant front is shaping up for next Monday with decidedly cooler, possibly the coolest air of the season, to arrive for Tuesday of next week.
