A tad less humid today, but the humidity returns this weekend

Today's Outlook: An area of high pressure will continue to sit over the Southeast U.S. today and Friday. This will keep some drier air over us, and that is even lowering the humidity a tad too. It will also limit the amount of rain we see to only stray showers. However, there is an upper-level low in the Central Gulf of Mexico that is slowly moving to the west. This will not form into anything, but it will set off some coastal showers that could move inland. Therefore, expect partly cloudy skies with only stray showers today. Highs will be in the lower 90s, and it will feel like 95-100.

Tonight will be mostly clear and not as muggy with lows around 70 north and upper 70s south each day. Looks like there will be one more refreshing night on the Northshore before the muggy weather returns.

Weekend Forecast: The weekend will see an increase in the moisture and humidity as a tropical wave moves across the Gulf and a cold front stalls just north of New Orleans. The cold front will not likely get below the I-20 corridor, but that is close enough to help get us some rain. Saturday and Sunday will be partly cloudy and hot with spotty storms each day. Highs will be in the lower 90s and lows in the 70s.

Saints' Game Day: The Saints open their season this Sunday! Who Dat!! The weather will be nice for tailgating before the game with partly cloudy skies and a slight chance for a shower with temps. in the 80s. There will be spotty storms for the Noon kickoff with temps. around 90°, so it is good the game is indoors! After the game (and hopefully a victory) it will be mostly cloudy and hot with spotty storms. Temps. will be in the 90s.

Tropics: There is a broad area of low pressure, now Invest 93L, about 350 miles east of the Leeward Islands. It is moving to the NW and has a low chance for development over the next 5 days. Forecast models show it moving to the NW and then curving out to sea.

There is also a disorganized tropical wave located 500 miles SW of the Cabo Verde Islands. It is battling some dry air and wind shear, so it has a low chance for development in 2 days. Then it will move into a more favorable area for development next week and it has a medium chance for development then. Models show it staying out at sea.

Elsewhere...the rest of the tropics are quiet.

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...

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...

The Unseasonably Cool Weather Continues

Short Term Forecast : It is a very cold morning across the Capital City with clear skies and temperatures in the 30s. A light freeze is expected! I hope that you brought in your plants last night. Take that jacket with you this morning. An area of high pressure remains over the Southeast U.S. today. This will keep us sunny and with the northwest winds over us, we will stay cool. High temperatures will be in the upper 50s. Another freeze is expected tonight for the Baton Rouge area. We will be clear with calm winds and very good radiational cooling. Low temperatures will fall into the upper 20s to lower 30s. The NWS has issued a Freeze Warning for areas along and north of the I-10/12 corridor from 2 AM to 8 AM Wednesday Morning. The freeze could last 2 to 6+ hours and that would be long enough to kill any vegetation. Make sure you bring in your plants or at least cover them tonight! Bundle ...
