More Heat Today, But A Cold Front Arrives This Weekend

Short Term Forecast:  We have a pretty nice start to this Tuesday with mostly clear skies and muggy temperatures in the 70s.
 

The ridge of high pressure in the mid and upper levels of the atmosphere will remain over us today.  This means we will have partly cloudy skies with only a stray shower or two popping up.  It will be hot and still humid with high temperatures in the lower to mid 90s.

You can expect a mostly clear night across the Capital City.  It will be sticky with low temperatures in the lower 70s.

Week Ahead:  The ridge will move to the northeast of Louisiana starting on Wednesday.  This will allow for some extra Gulf Moisture to stream over Louisiana.  We will remain partly cloudy in the afternoon with a slightly better chance of a shower popping up.  Highs will be in the lower 90s and lows in the lower 70s on Wednesday Night with a few clouds.

More moisture moves over us on Thursday and when you combine that with the daytime heating we will have isolated showers and storms developing all around Southeast Louisiana.  Otherwise, we will have a mix of sun and clouds with highs in the lower 90s.  Thursday Night will be partly cloudy and muggy with lows in the lower 70s.

The weather will go downhill on Friday as a trough of low pressure sends a cold front into Louisiana.  This will tap into that rich moisture and set off scattered showers and thunderstorms.  Some storms could have some heavy rain at times.  Highs will only get into the upper 80s.  Friday Night will be mostly cloudy with scattered showers.  Lows will be in the lower 70s.

Weekend Outlook:  The cold front will move into Baton Rouge on Saturday.  This will bring more scattered showers and thunderstorms with heavy rain at times under mostly cloudy skies.  Highs will be in the upper 80s.  The front will move through town on Saturday Night and likely stall along the Louisiana Coast.  We will stay mostly cloudy with a few showers.  Lows will be in the upper 60s.

The front will remain along the Louisiana Coast on Sunday, but it will be slowly falling apart.  We will have partly cloudy skies with lingering isolated showers and storms.  Highs will be in the upper 80s and lows in the upper 60s on Sunday Night with mostly clear skies.

Tropical Outlook:  Tropical Depression Ingrid has dissipated over the mountains of Mexico.  NHC has issued the last advisory for that system as it has lost its well-defined center of circulation.


Tropical Storm Humberto continues to churn in the middle of the Atlantic.  It is located about 1150 miles to the WSW of the Azores.  Winds are 40 mph and the pressure is 1007 mb according to the NASA Global Hawk Mission.  It is forecast to move to the north over the next few days and get a little stronger.


There is also an area of low pressure centered near the coast of Belize.  It is producing a large area of disorganized showers and thunderstorms over the NW Caribbean.  The low is forecast to move WNW across Belize and the Yucatan today.  Then it will emerge in the Bay of Campeche on Wednesday.  Upper-level winds are somewhat favorable for some development in the next 2 days and the NHC is giving this system a low chance of becoming a tropical cyclone during that time.  Then the low is forecast to become stationary over the Southwestern Gulf of Mexico by the end of the week.  At that time conditions are expected to be still favorable for additional development.  NHC is giving it a medium chance of becoming a tropical cyclone during the next 5 days.


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

Stay cool, enjoy the sun and have a nice day! -Dave

Major Snowstorm Headed To Northeast US Tomorrow

For all of my friends and family that live in the Northeast US...here is my latest analysis of the winter storm heading your way on Friday into Saturday: The same area of low pressure that brought the heavy rain and thunderstorms to Louisiana last night and this morning will be moving up the East Coast on Friday.  It will get much stronger and become a  Nor' Easter that will impact all the major cities from Philly to NYC to Boston as well as inland areas. Delmarva to NJ Coastal Areas :  Winter Storm Warning in effect from Friday AM until Saturday AM!  It looks like it will start out as a brief period of snow along the coast in the morning then change into a windy rain during the day.  Then go to a heavy snow late Friday into Saturday Morning.  Snow accumulations of 4-8" are possible.  Some minor ice accumulations are possible too. Winds will be sustained around 30+ mph and coastal erosion will be possible too. NE PA : Winter Storm Warning from 10 am Friday until 7 am Sat

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 up! Week Ahead :  The area of high pressure will stay put through

Today Is The 5th Anniversary of Hurricane Gustav

Early in the morning on September 1, 2008, Labor Day, Hurricane Gustav made landfall near Cocodrie, LA.  It was a strong category 2 hurricane with 110 mph winds.  At one point, right before Gustav made landfall over Western Cuba, winds were as high as 150 mph (Category 4).  It did weaken as it crossed Cuba, but did regain strength as it sat in the middle of the Gulf as it became a Category 3 storm with winds of 115 mph.  This storm became the worst one ever to impact Baton Rouge, LA.  Sustained winds around 70 mph with a 91 mph wind gust was reported at Baton Rouge Metro Airport, 108 and 117 mph wind gusts were reported in Houma, LA.  That caused significant damage and, at one point, the entire city of Baton Rouge was without power. Hurricane Gustav moved slowly inland and the eastern-edge of the eye wall moved along the Mississippi River into Baton Rouge.  It continued northward through West Feliciana & Pointe Coupee Parishes.  The worst damage was seen along this line.  Area
