Record Breaking Arctic Barreling Through The US

 

A record breaking cold front will continue barreling through the central US and Midwest overnight.  While temperature drops have been impressive, the coldest is still pushing through the upper Midwest and will track toward the Ohio Valley over the coming days.  We expect many records to get broken, especially over the Southeastern US where temperatures this chilly usually don’t push this far south.  There is a weather system spinning up over the Southeast along a strong temperature gradient.  This will bring areas of moderate snow to the Mid-Atlantic and Northeast into Monday.  As the low pressure system rapidly strengthens, strong winds will combine with bitter cold temperatures, leading  to extreme wind chill values of -20 to -40F.   It’s clear nat gas and energy demand will be extremely high, but other commodities like oranges and other fruit crops could be seriously affected.  We will be tracking the intensity of the cold over the coming days, as it will be one for the record books.

 

The image is of the latest temperatures across the US early Friday evening.  The coldest air has now pushed into northern Plains with temps of -20F and colder filterning in.  Note how strong tehe cold front is across northern Missouri, some 60F degrees!

Note how strong the cold front is across western Tennessee into Louisiana.  This gradient is the focus of where low pressure will continue to spin up and strengthen and then push toward the Northeast. Single digits to teens are about to push into northern Texas and Arkansas.  Mild temps across the eastern coastline will rapidly drop Monday.

 

This is the Infrared Satellite imagery loop showing the low pressure system rapidly developing. Depending on when you view this, since it is live, it shows yellows and oranges blossoming over the Northeast, characteristic of strengthening low pressure systems, which is really the cloud tops cooling due to lift in the atmosphere. Note the blue colors over the Midwest which the satellite is thinking is clouds, like off the Baja coast, but its really because the air mass is so brutally cold the satellite only expects to see them higher up in the atmosphere as clouds.

 

Sunday evening weather radar shows areas rain ahead of the cold front and snowfall behind it.  The heaviest snow is over Indiana and into Ohio while rain showing from around the orange colored pixels and eastward.  The low will strengthen overnight and become of a more organized cyclone with strengthening winds and intensifying snow bands.

The heaviest snow is over Indiana and into Ohio while rain is falling from around the orange colored pixels (greater than 35 dBz) and eastward. The low will strengthen overnight and become a more organized cyclone with strengthening winds and intensifying snow bands.

 

Comapring Sunday morning temperatures versus Saturday shows the Arctic outbreak has pushed well into the Plains and Midwest overnight, as temperatues plunge more than 30F over many of these regions compared to yesterday. In addition, the Northeast has warmed condiderably as last weeks cold modifies with southerly winds ushering warmer conditions ahead of the deep freeze with temps warming 15-30F across all of the eastern US.

Comparing Sunday evening temperatures versus Saturday evening shows the Arctic outbreak has pushed well into the Plains and Midwest with temperatures plunging more than 30F over many of these regions compared to yesterday. In addition, the Northeast has warmed considerably as last weeks cold modifies with southerly winds ushering warmer conditions ahead of the deep freeze.

These are the forecast overnight lows as the deep freeze pushes into the Southeast.  Tuesday morning lows will be the coldest for many areas during this cold snap.  Note the single digits even as far as Georgia and Alabama with teens and 20s for northern Florida.
