Nationally, a strong weather system is moving through the Southeast with some severe thunderstorms. This system will weaken as the associated low moves toward the Great Lakes. Behind it, another chilly blast of air develops over the Rockies. It will plunge into the Central U.S. and eventually bring chilly weather for April to the Eastern part of the country later in the week.

In the Caribbean, relatively tranquil conditions prevail as dry and stable southwest flow continues over the area. Occasional strong trades winds continue due to high pressure anchored to the north over the Atlantic. Little change is expected through the next few days.
