Scattered To Numerous Showers and Storms Today

Short Term Forecast: We have a mostly cloudy and muggy start to this Wednesday Morning across the Baton Rouge area. Temperatures are in the upper 60s.

Get ready for some rain and thunderstorms today. This is thanks to a plume of deep tropical moisture streaming north from the Caribbean. At the same time a trough of low pressure will be inching closer to Louisiana. Combine that with daytime heating and a sea breeze, and we will get scattered to numerous showers and thunderstorms. A few storms could be strong with gusty winds and heavy rain. High temperatures will be in the mid 80s.

The bulk of the rain will end tonight, but we could still have a spotty shower popping up overnight. Otherwise, it will be partly to mostly cloudy with lows in the lower 70s.

Rest of the Week: The deep tropical moisture will remain over us on Thursday as well as the trough of low pressure. A weak disturbance is being pick up by the forecast models and that will help to give us a greater chance for rain. Therefore, expect more numerous showers and storms with heavy rain on Thursday. It will still be very warm and humid with highs in the mid 80s. Thursday Night will be mostly cloudy and steamy with lows in the lower 70s.

Some drier air will move over the state on Friday, and that will help to reduce the amount of rain we will have. Expect partly cloudy skies with isolated to scattered showers and thunderstorms. Highs will be around 90. Friday Night will be partly cloudy and very muggy with lows in the lower 70s.

Weekend Outlook: We will still have some unsettled weather this weekend, especially on Sunday. The

deep tropical moisture will be east of Louisiana by Saturday, but we will still have a very humid air mass over us. It will be partly cloudy with scattered showers and thunderstorms popping up during the afternoon and evening on Saturday. Highs will be in the upper 80s before it starts to rain, and lows will be in the lower 70s on Saturday Night.

A weak cold front will move into Louisiana on Sunday into Monday. This will tap into the humid air and set off scattered to numerous showers and storms. Some storms could be strong with gusty winds and heavy rain. High temperatures will be in the upper 80s and lows in the lower 70s.

Be sure to take your umbrella with you and have a good day! -Dave

Comparison between Hurricane Matthew's possible forecast track loop vs Hurricane Betsy's

Some of you have been calling to say that Matthew's forecast to do a loop in the Atlantic Ocean off the SE U.S. is the same as what Hurricane Betsy did back in 1965. Well...that is not true. Betsy formed on August 27, 1965 just off the Leeward Islands. It quickly became a tropical storm on the same day, and then became a hurricane on August 29. It made a few loops in its track with one north of Puerto Rico and a second north of the Bahamas. There is a strong area of high pressure that was preventing Betsy from moving to the north, and that is what caused it to loop. After the second loop, it then moved SW across the Bahamas, then turned west to move over far South Florida and then into the Gulf. It eventually turned to the NW and quickly tracked right to New Orleans where it made landfall as a major hurricane on September 9th. Hurricane Matthew formed in the Atlantic east of the Leeward Islands as a tropical storm on September 28. It quickly moved west into t...

Flash Flood Watch now until Thursday Evening for WBRZ Viewing Area

The NWS in Slidell, LA has issued a Flash Flood Watch for all of the WBRZ Viewing Area starting now and continuing until Thursday Evening. Rain has been falling for the last few hours and we have already picked up over 1.30" in Baton Rouge. This is WAY more than the forecast models were predicting for this time. The area of low pressure continues to develop over South Texas and a warm front will move up from the Gulf of Mexico by Wednesday Morning. This will spread widespread rain and a few thunderstorms over Southern Louisiana all night and into Wednesday. Then it looks like we will taper off the rain to just scattered showers during the day on Wednesday. On Wednesday Night, a cold front will move out of Texas into Louisiana. As this happens, a squall line of thunderstorms is expected to move ahead of it and through Baton Rouge on Thursday Morning. Some of these storms could be strong to severe with damaging winds and a few tornadoes. ...

The Great Flood of 1983

It was 30 years ago that the Baton Rouge area experienced what is likely the worst flood in its history! On April 5-9, 1983 we were hit with 6 to 13 inches of rain from a slow-moving storm. This rain quickly ran off into the Amite, Comite, Tickfaw and Tangipahoa River Basins. Some of the highest rainfall totals were in the headwaters of the Amite River in the Felicianas and South Mississippi. Also, there were some strong easterly winds which slowed down the water from draining into Lake Maurepas and Pontchartrain. These were some of the reasons why the flooding occurred in Baton Rouge & Denham Springs. The weather map to the right shows the weather for April 8, 1983. A stalled front over the Southeast U.S. lead to the heavy rain event and flooding. The rivers quickly rose and spilled out of their banks. The rain didn't stop, so the water continued to rise and rise. Rivers rose to what are still the record levels. The Amite in D...
