More Bitter Cold Weather Today

...Hard Freeze Warning Until Noon Today...
...Hard Freeze Warning From 6 PM Tonight Until 9 AM Wednesday...

A Bitter Cold Day:  We start out this Tuesday Morning with mostly clear skies as some high clouds remain over the city.  It is bitter cold with temperatures in the upper teens to lower 20s.  PLEASE bundle up as you head to school and work today.  It will remain cold all day long!

An area of high pressure will sit over us today and that will make for a beautiful sunny day.  Unfortunately, it will stay very cold all afternoon.  The Arctic Air will still be over us today and that will not allow us to warm up much.  We will only have high temperatures in the upper 30s to around 40 in the Baton Rouge area.  If you have to be outside for an extended period of time today be sure to dress in layers to stay extra warm!

We will have one more night of the bitter cold with clear skies.  Low temperatures will be in the lower 20s.  Another hard freeze is expected and the NWS has issued another Hard Freeze Warning from 6 PM tonight until 9 AM Wednesday.  This hard freeze could last 12 to 15 hours with temperatures below 26°.

Always remember the "P's":  Be sure to wrap any exposed pipes outside of your home!  This cold blast may be cold enough to burst some pipes - especially in areas that may not get above freezing on Monday.  PLEASE have a warm place for any outdoor pets.  Lastly, check on those people that may not have any heat.

Polar Vortex? What is that?  You have have likely heard the term polar vortex on the news over the last few days, and you are probably wondering what that is?!?  A polar vortex is a persistent very large area of low pressure (an area of low pressure is called a cyclone or vortex) that contains dense VERY cold air that's normally bound in by a jet stream (river of winds where commercial airplanes fly) over the North Pole.  It always exists up there!  Usually it sits up over the North Pole, but when the jet stream dips a piece of it can break off and move to the south.  In this case, the jet stream dipped south over the USA.  Sometimes it also moves over Siberia on the other side of the Earth.  They are very large and that is why the cold air can sink all the way to Baton Rouge.  I hope that makes some sense?!?  Here is a graphic the NWS in New York City created describing it: 

Warmer Weather Arrives Tomorrow:  The area of high pressure will move east of Louisiana on Wednesday and that will take the coldest air with it.  This means we will have a slight warm-up tomorrow with mostly sunny to partly cloudy skies.  High temperatures will be in the lower 50s!  Wednesday Night will still be cold, but not near as bitter cold with lows in the upper 30s.

The warming trend continues on Thursday and Friday as southerly winds return to the state.  We will have some Gulf Moisture transported in too and that will lead to partly cloudy skies on Thursday with highs in the mid 60s and lows in the upper 40s.

A cold front will move toward Louisiana on Friday.  It will be mostly cloudy, warm and more humid for the first part of the day.  Then scattered showers and a few thunderstorms will start moving into Baton Rouge during the afternoon and evening hours.  Highs will be in the upper 60s.  Scattered to more numerous showers and storms will move into town on Friday Night ahead of the cold front.  Lows will be in the upper 50s.

Weekend Rain:  The showers and storms will continue on Saturday, especially for the morning hours, as the cold front moves into Baton Rouge.  Otherwise, it will be mostly cloudy and warm with highs around 70.  Look for a few lingering showers on Saturday Night as the front stalls along the coast with lows in the lower 50s.

Some rain will lingering into Sunday as the front remains stalled along the coast with partly to mostly cloudy skies.  Then the rain will move east of Louisiana by Sunday late-afternoon.  Highs will be in the 60s and lows in the 40s on Sunday Night.

Please stay warm today and have a good one! -Dave

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 Wednesday. …

Major Snowstorm Headed To Northeast US Tomorrow

For all of my friends and family that live in the Northeast 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 Saturday! …

Deadliest and Strongest Tornadoes In Louisiana History

If you are wondering what is the deadliest tornado ever to hit in the Baton Rouge was back on April 24, 1908 in Amite, LA to Purvis, MS.  (Grazulis, Thomas P. (1993). Significant Tornadoes 1680-1991: A Chronology and Analysis of Events. Environmental Films)  143 people lost their lives.  This was part of the 1908 Dixie Tornado Outbreak.  The storm started around 11:45 AM near Weiss, LA in Livingston Parish and tracked toward St. Helena Parish.  2 people were killed in Denham Springs and 2 in Montpelier.   Then it tracked toward Amite, LA where a path of damage was around 2 miles wide.  29 people were killed there.  It then traveled on the ground to Purvis, MS where the greatest damage was and most of the lives were lost.  The damage path was around 155 miles long.  

The F-Scale and  EF-Scale didn't exist then, so it was not given a rating at the time.  However, using recent technology and assessments, the storm would have been given an F-4 or EF-4 rating.
