KATC StormTeam 3 Weather BLOG

A significant storm system is developing in the southwestern states while tropical moisture from the Pacific and Tropical Storm Paul are getting caught up in the mix.  The latest fly in the ointment today is that the computer models are not consistent in their depiction of moisture fields with this system.  The models are slowing down the progress of the upper low associated with this system so the rains may not be over with until late Thursday night or very early Friday morning.  As I alluded to in yesterday’s blog, the QPF folks are indeed upping the rain totals area-wide, and the local NWS is also upping their expected rain totals.  Generally we should start off with patchy light to moderate rains tomorrow afternoon with embedded heavier convection developing tomorrow evening, especially in the western areas of Acadiana.  On and off showers and thunderstorms will prevail tomorrow night through Thursday night, with the slight risk of severe weather also part of the equation.  So expect at least another couple of inches of rain over the next few days, and possibly a few strong storms.  But at least the weekend is still looking nice and cool.  We probably won’t clear out until Friday night so look for cloudy, breezy and cool conditions for Friday.  Another factor with this dynamic storm system will be the wind; strong south to southeast winds will be with us tomorrow afternoon through Thursday evening so tides 1-2ft normal wouldn’t be out of the question.
