Severe Weather Possible Late Tonight & On Monday

The old cold front that brought us the rain and storms last week will come back north as a warm front tonight/Monday Morning.  As this happens, another cold front will move in from the west.  We will become very unstable as the warm and humid air is ushered in from the Gulf, and it will become breezy too.  All of this will allow scattered to numerous showers and thunderstorms to pop-up.  The rain & storms will start this evening, but will become much more widespread on Monday.  There may be some breaks in the rain & storms, but it is not expected to come to an end until Monday Night.

Any of the storms that develop could become strong to severe!  This severe weather event looks to be stronger than the last few and we could have a possible outbreak!!  That means we could have more widespread severe weather verses just a small threat.  The reason is that we will be much more unstable and more severe weather variables will be in place this time.  The SPC has us in a Slight Risk for severe weather due to the mentioned factors.  We could have large hail (1"+ in size), damaging winds (60 mph or greater), and even a few tornadoes on Monday.  The threat will remain until the cold front passes through Baton Rouge and that should happen by Monday Evening as of right now.  It is likely that a squall line of thunderstorms will move through with the cold front by Monday Evening, and this will also give us the chance of seeing some severe weather with damaging winds.

On top of the severe weather threat, we will also have heavy rain falling.  The forecast models are indicating we could pick up 1 to 3 inches or rain with a few spots getting closer to 6 inches.  This could cause Flash Flooding and the NWS in Slidell, LA has issued a Flash Flood Watch for Livingston, Tangipahoa, St. Helena Parishes and Amite & Pike Counties in Mississippi from 9 PM tonight until Monday Evening.  Those Parishes/Counties are expected to get some of the heaviest rains.  Depending on how much rain fall, more Parishes/Counties could be added according to the NWS.

Please stay tuned to WBRZ, WBRZ Weather Channel and my Facebook & Twitter feeds for additional updates - especially on Monday.  I will have full coverage on 2une In Monday Morning.

Stay safe and aware! -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...

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 ...

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...
