KATC StormTeam 3 Weather BLOG

It’s going to be a wet and stormy weekend as low pressure develops rapidly in the Northwest Gulf of Mexico tomorrow.  Fair and chilly conditions early tonight will yield to increased high cloudiness tomorrow.  Look for cloudy, breezy and cool conditions tomorrow with rain showers developing from the west to the east during the day.  Highest rain chances with embedded thunderstorms will likely Saturday night and into Sunday.  Quantitative Precipitation Forecasts remain robust with 2-4 inches likely by Sunday evening, with a few isolated areas possible receiving a few inches more.  So there will likely be the risk of some localized street flooding by Sunday. Depending on the path of the low there may be a severe threat for Saturday night into Sunday as well with the greatest risk likely along the coast and across SE Louisiana.  The best bet for the strongest storms would be for a round Saturday night and then with another round for Sunday afternoon.  Although pressures will not be that low with the low that develops, the pressure gradient will tighten a fair bit allowing northeast winds near 15-25mph inland and near 20-30kts or higher offshore.  Be careful out there if you have to travel this weekend, and as always, allow plenty of time to get to your destination.
