More Heat Today, A Cold Front Friday Night And The Tropics Are Active

Short Term Forecast:  We have a pretty warm and muggy Thursday Morning with mostly clear skies and temperatures in the 70s.

The ridge of high pressure that has been sitting over us the last few days will build to the west today.  This will keep us mainly dry and hot with partly cloudy skies.  A few showers are possible, but I'm not expecting many of you to see rain.  High temperatures will be in the lower to mid 90s.

A few clouds will linger over the city tonight and it will stay warm.  Low temperatures will be in the lower 70s.

The weather will start to change a little on Friday.  A trough of low pressure in the upper-levels of the atmosphere will move down along the Eastern U.S.  This will send a cold front toward and through Baton Rouge.  The front will arrive late in the day and it will help to set off a few showers.  Therefore, we will be partly cloudy and hot with a few showers.  Highs will be in the lower 90s.  Friday night will be partly to mostly cloudy with a few showers as the cold front stalls along the Louisiana Coast.  Lows will be in the lower 70s.

Weekend Outlook:  The front will continue to stall along our coast.  At the same time, an area of low pressure will be moving across the Bay of Campeche.  This low will send some tropical moisture toward Louisiana all weekend and that will help to set off a few showers.  Saturday and Sunday will both be partly cloudy with isolated showers and a few storms.  Highs will be in the lower 90s and lows in the lower 70s each day.

Tropical Outlook:  Gabrielle is now a tropical depression.  It is located about 190 miles WNW of Bermuda with 35 mph winds.  The pressure is 1010 mb.  The depression will move to the NNE over the next few days toward Nova Scotia.  It may become a tropical storm again, but it will stay out at sea.


Hurricane Humberto continues to be well organized as it sits around 440 miles NW of the Cape Verde Islands.  Winds are 85 mph and the pressure is 982 mb.  It is moving to the N at 14 mph and will turn to the NNW to WNW over the next few days as it moves out to sea.  It is also forecast to weaken over the cooler waters.

Lastly, I'm watching an area of low pressure (Invest 93L) located over the Yucatan Peninsula.  It will emerge into the Bay of Campeche later today or tonight. As long as it remains over water, there is a chance this low could form into a tropical depression by the weekend.  The forecast models show it moving to the west and into Mexico.  However, some moisture could stream north toward Louisiana early next week from this system.  This would increase the chance of rain over Baton Rouge, but we would not be directly impacted by this system.

Elsewhere...there is a broad area of low pressure located 550 miles east of the Leeward Islands.  Conditions could become somewhat favorable for development over the next few days as it moves to the west and northwest.  NHC is giving it a low chance of becoming a tropical cyclone during the next 5 days.

Have a great day and stay cool in this heat! -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...
