Happy Halloween!! ...Strong To Severe Storms & Heavy Rain Possible Today/Tonight... Short Term Forecast :  We have a very warm and humid morning with mostly cloudy skies across Southeast Louisiana.  A few showers could move through town during the morning commute, but most of you will remain dry. A strong trough of low pressure will send a cold front into Louisiana and through Baton Rouge today.  It will be very warm and humid ahead of the front and that will make the atmosphere unstable.  This will also allow for scattered showers and storms to develop during the afternoon hours.  Some of the storms could be strong with gusty winds at times.  High temperatures will be in the lower 80s. More numerous showers and thunderstorms will move into Baton Rouge during the Trick-or-Treat hours of 6 to 8 PM.  These storms have the potential to be strong to severe!!  Obviously, this isn't good for anyone going out to get candy.  There is a ...

Short Term Forecast :  We have a partly to mostly cloudy Wednesday Morning with patchy fog around Baton Rouge.  Watch out for some low visibilities near 1/4 mile.  It is mild with temperatures in the 60s. We will have another unseasonably warm afternoon across the Capital City.  High pressure is still off to the east of Louisiana and that is allowing southeasterly winds to pump in the warm and humid air over us.  It will become a little breezy later today with winds around 10 to 15 mph.  All of this moisture will give us a mix of sun and clouds with high temperatures in the mid 80s. The clouds will linger over the city tonight and it will be pretty muggy.  Low temperatures will be in the upper 60s. Halloween Forecast :  Unfortunately the weather does not look good for Halloween this year.  A trough of low pressure will send a cold front across the Baton Rouge area by Thursday Night.  We will have some scattered showers and storm...

Short Term Forecast :  We have a partly cloudy morning with some patchy fog across Southeast Louisiana.  It is mild with temperatures in the lower 60s. Get ready for some Spring-like weather this afternoon thanks to an area of high pressure sitting over the Southeast U.S.  This is giving us southeast winds which are pumping in the warm and humid air from the Gulf of Mexico.  We will be partly cloudy with high temperatures in the mid 80s today. Some clouds will stick around tonight along with areas of patchy fog.  It will be mild and a little muggy with low temperatures in the mid 60s.

Short Term Forecast :  We have a much warmer and slightly more humid start to this Monday.  The skies are partly to mostly cloudy and there is some patchy fog.  Temperatures are in the lower 60s. The warm and more humid air mass will stay over Baton Rouge today thanks to winds coming out of the southeast as an area of high pressure sits over us in the mid to upper levels.  This will lead to partly cloudy skies along with a spotty shower or two.  High temperatures will be in the lower 80s. Some clouds will stick around overnight and it will be a little muggy.  Some patchy fog is also possible.  Low temperatures will be in the lower 60s.

Chilly Temperatures:  This morning we got down to 47° in Baton Rouge!  This was the first time we hit the 40s this season.  When you compare that to the last 5 years, this was pretty late in the season.  In 2012 we were in the 40s in early October! Short Term Forecast :  We have some very comfortable weather across the Capital City on this Thursday Evening.  This skies are clear and temperatures will fall from the 70s into the 60s during the evening hours.  There is also some smoke around town thanks to the burning of the sugar cane fields.  Overnight, it will be clear and not as chilly as last night.  Low temperatures will be near 50.  You may still want that light jacket or sweater on Friday Morning. A weak and dry disturbance, or short wave, will move across the Deep South early on Friday Morning.  This will not have any moisture to work with, so we will stay dry.  It will bring us a reinforcing shot of cooler air as ...

Short Term Forecast :  We have a mostly cloudy morning across the Capital City with a few areas of mist and drizzle.  Temperatures are in the upper 50s to lower 60s.

Short Term Forecast :  We start this Monday with partly cloudy skies and cool temperatures in the 50s.

The warm front will get to around I-10 and that will draw up some Gulf Moisture over Baton Rouge this evening.  This will help to set off some showers.  More rain will move inland tonight as the area of low pressure sits along the Louisiana Coast, and it will be moving off to the east.  We will have scattered showers around Baton Rouge, but the bulk of the rain will be south of I-10 tonight.  Some heavy rain can be expected for the Coastal Parishes.  Otherwise, we will be mostly cloudy with lows in the upper 50s.

Short Term Forecast :  We will have a warm and muggy night across the Capital City with some dense fog for your Friday Morning Commute.  Low temperatures will be in the mid 60s. Friday will be even warmer and more humid thanks to the ridge of high pressure moving east of Louisiana.  This will bring back southerly winds and they will pump in the moisture from the Gulf.  Expect the fog to dissipate by 9 AM and then the clouds will start to dissipate by 11 AM.  Then we will have partly cloudy skies during the after hours.  High temperatures will be in the mid to upper 80s.

Short Term Forecast :  Once again we have a very pleasant start to the day with clear skies and cool temperatures in the 50s.  If you needed your jacket the last few mornings, you will want it again today. The ridge of high pressure is still sitting over us this afternoon and that will keep the awesome weather in Baton Rouge.  We will be sunny and delightful just like the last few days.  However, it will be a little warmer with high temperatures back in the lower 80s. We will not be as cool tonight compared to the last few nights.  This is thanks to some moisture that will start to return to the area from the Gulf.  This will give us mostly clear skies with patchy dense fog.  Low temperatures will be near 60. Week Ahead :  The area of high pressure will move to the east of Louisiana starting on Thursday.  This will shift the winds from the north to the southeast and that will pump in the Gulf Moisture over us.  We will have part...

Latest Information :  Tropical Storm Karen showing the effects of wind shear and drier air this morning.   The wind shear is about 20-25 knots and that is preventing most of the thunderstorms from wrapping around the center of circulation.  That means the center is exposed (you can see that on the satellite image below) and at the moment the storm is a little weaker with winds of 60 mph, and the pressure is up to 1003 mb.  Karen is moving to the NNE at 10 mph. There is a ridge of high pressure located to the east of Karen and it is riding along the western edge of it.  At the same time, a trough of low pressure will be sweeping across the U.S. and that draw Karen northward toward the Northern Gulf Coast.  The forecast models are still all over the place.  A few of them have it getting weaker and making a landfall over Louisiana, a few more keep the storm stronger and making a landfall more to the east over Florida.  NHC has taken a middle of ...

Latest Information : According to the latest info from the Hurricane Hunters, we now have Tropical Storm Karen in the Southern Gulf of Mexico.  Winds are sustained at 60 mph, pressure is 1005 mb and it is tracking to the north at 10 mph.  At the moment, this system is forecast to track to the north toward the Northern Gulf Coast States of LA to the FL Panhandle.  Tropical Storm and Hurricane Watches are in effect for the SE LA Coast through the Florida Panhandle. Strength : Conditions are favorable today and tomorrow for some strengthening, and Karen is forecast to become a weak hurricane.  It will move over some warm Gulf waters and that is fuel for the storm.  However, as Karen approaches land the conditions will not be favorable by Saturday as it will move through some strong wind shear.  Also, there is a lot of dry air over the Central and Western Gulf, and this will limit the amount of strengthening.  The cold front is still forecast to move ...
