Hotter and Slightly Less Humid Today, Plus A Look At The Tropics

Short Term Forecast:  The cold front has moved south of Baton Rouge this morning.  We have partly to mostly cloudy skies with temperatures ranging from the upper 60s to lower 70s.


The cold front will stall along the Louisiana Coast this afternoon.  It will be close enough to help set off a few showers and storms in Baton Rouge with partly cloudy skies.  Some drier air will start to move into town today and that will help to make it feel a little less humid.  High temperatures will be back around 90.

Expect some mostly clear skies tonight and it will turn a little cooler!  Lows will fall to the upper 60s, and that will feel pretty refreshing.

The front remains stationary along the Coast and a trough of low pressure sinks into the Southeast U.S. This will give us more dry air on Friday and that will make for a pretty nice day.  We will be partly cloudy with only a slight chance of a shower.  Highs will be in the lower 90s and lows in the upper 60s.

Weekend Forecast:  I'll be watching the low in the Gulf of Mexico to see how it evolves.  Right now, the forecast models are all over the place, so we are still in a wait and see mode.  The weather patten shows the trough remaining over the Southeast U.S., and that will help to keep the nice weather over Baton Rouge.  We will be partly cloudy with only spotty afternoon storms popping up.  Highs will be in the lower 90s and lows in the lower 70s.

We will start to become more humid on Sunday with the trough starting to move to the east and the stationary front still draped across the Northern Gulf of Mexico.  We will be partly cloudy with isolated showers and storms developing during the afternoon.  Highs will be in the lower 90s and lows in the lower 70s.

*NOTE...if a tropical system forms in the Gulf of Mexico that will change the forecast for this weekend!

Tropical Outlook:  I'm still closely watching the tropical disturbance, Invest 92L, in the Northwest Caribbean.  It is slowly moving closer to the Yucatan Peninsula and will eventually move over it later tonight/tonight.  There is a chance the system could become a tropical depression before it moves over land.  It will emerge in the Southern Gulf of Mexico on Friday, and then there are all sorts of scenarios that are possible.  Upper-level winds are forecast to be a little stronger over the Gulf and that could prevent the system from getting very organized.

The forecast models are all over the place with the evolution of this system.  One set has it moving north toward LA/MS/AL, and the others have it going into Old Mexico.  The trough of low pressure over the Eastern U.S. and stationary front sitting along the Northern Gulf of Mexico will have an impact on what this system will do.  The trough will help to keep some decent wind shear over the Gulf.  If the disturbance can linger over the warm Gulf Waters, and survive some wind shear, then there is a chance it could develop into something.  There is a high chance, according to the NHC, that this system will become a tropical system in the next 5 days.  Either way, deep tropical moisture will still stream northward toward the Gulf Coast States and that will spread heavy rain from SE Louisiana to Florida.

Hurricane Hunters are scheduled to investigate this system today, so we will find out later what they find.  Needless to say, this is a wait and see mode as to what it will do.

Last Night, Invest 93L became Tropical Depression #5 way out in the Atlantic, and now is has strengthened into Tropical Storm Erin.  It is located 65 miles WSW of Brava in the Cape Verde Islands.  Winds are at 40 mph and the pressure is 1007 mb. It is moving to the WNW at 16 mph.  This system is forecast to stay a tropical storm over the next 5 days as it moves out into the open Atlantic Ocean.

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

Enjoy the sunshine & slightly lower humidity today.  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 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 ...
