Strong Storm Hammering Midwest and Southeast

 

A massive springlike storm continues to hammer the Midwest and eastern US. The satellite and radar imagery shows a nicely wound up cyclone stretching from southern Canada to the Gulf of Mexico. There are two impressive features with this storm, the first being the line of very strong thunderstorms tracking through the Southeastern US with severe weather. The second is the wrap around band of snow over the Great Lakes region. There is a very tight pressure gradient around the low pressure center that is leading to some very gusty winds. The following images show the highlights of the storm nicely. A fresh first week of March pattern update will be forthcoming later this morning.

 

 

1)  The center of the strong winter storm is moving out of the Great Lakes with a very nice wrap around commma head producing snow over Minnesota and Wisconsin.  This is a well wrapped up cyclone with a deep low pressure center, which leads to very strong winds at the surface.

 

2)  A new jet stream feature has taken over at the base of the trough and is now driving a line of strong thunderstorms through the Southeast.

 

3)  So goodbye to the big warm up.  The ridge of high pressure that brought a couple days of milder temperatures is about to get pushed off into the Atlantic by the strong storm sweeping through the eastern US.

 

4)  Cooler temperatures are filtering through the northern Plains on the back side of the massive weather system.  It’s not exceptionally cold air coming down, but open the door for a much colder blast this weekend.

The image shows isobars at the surface which represent lines of equal pressure. It is easy to find the low pressure center over the Great Lakes. Because there are so many lines packed together tightly strong winds are expected as the atmosphere tries to adjust between the very low pressure with the storm and higher pressure surrounding it.
