The weather, currently.

A very cold night ahead

After one of the coldest days you can have in late March, temperatures tonight will fall to the upper teens and lower twenties. There will likely be some damage to early blooming trees and shrubs, as this kind of cold is pretty unusual. Although sunshine will help to boost temperatures to between 35 and 40 Tuesday afternoon, it will still be very dry with low dew points. The cold remains in place Tuesday night, but by Wednesday temperatures get back up into the 50s along with more sunshine. A storm system brings some wet weather for the end of the week, but it will be mild so there's no danger of any frozen type of precipitation. —Dave Epstein

What you need to know, currently.

Tornadoes are some of the weirdest extreme weather events. The light becomes strange, you hear a roar, and then the sky—suddenly murderous—reaches down to crush everything beneath it. The United States is a tornado country, with no close competitors. We average about 1,200 a year—higher than the yearly average for all of Europe and Canada combined.

“Tornado Alley” is generally regarded as the area stretching from central Texas up to Canada, but that term can be misleading. The tornados of the midwest tend to cut a more dramatic figure, easier to photograph, with better defined funnels. While the tornadoes of the South tend to be obscured by cloud cover and much more deadly—both because of population density in the South and because tornadoes there are more likely to take place at night.

There is some evidence that climate change is causing tornadoes to shift east. New Orleans and the surrounding area, which is recovering from Hurricane Ida and was hit by an E3 tornado last Tuesday is due for more severe weather later this week.

A low pressure system makes landfall along the California coast and moves to the South on Tuesday and Wednesday. The region could see strong winds, rain and potential tornados.
