Wednesday Evening Isaac Update

Posted by Keith Gibson | August 29, 2012 / 04:38pm | Top Story, Local News, Weather
Tropical Storm Isaac continues to move at a snails pace across southern Louisiana.  A slow WNW movement is expected during the next few days.  Recent computer model data continue to suggest that our area will remain on the northeastern fringe of the system as it lifts northward during the rest of the work week. 

Skies will be partly to mostly cloudy tonight across our area.  If we have any showers out there tonight then they would most likely be in our southern and western counties.  Lows will be in the mid 70s. 

There is a 40% chance of showers and weak storms in our area during the day Thursday.  Our southwestern counties look like they will have the highest risk for rain since they will be located closer to the core of Isaac.  These areas would also have the highest risk for one of those brief, spin up tornadoes that are typical on the east side of a land-falling tropical system.   Rain chances will be more scattered  farther to the northeast.  High temperatures will be in the mid 80s and breezy ESE winds will continue between 10 and 25 mph. 

Rain chances will continue Thursday night and Friday as the remnants of Isaac spiral north into Missouri.  We're still cautiously optimistic that the rain threat will be waning by the time high school football games are ready to begin.  Afternoon temperatures will be in the upper 80s.

Saturday will feature just a 20% chance of showers and storms during the day along with seasonably warm highs near 90.
