Snow in the Rockies; Showers and Thunderstorms Along the Gulf Coast; Potential Winter Storm for Northern Mid-Atlantic and Interior New England

A winter-like pattern will continue over much of the Lower 48 over the next few days, with snow stretching from the Rockies today into the Middle Mississippi Valley on Monday. Showers and thunderstorms will develop along the Gulf Coast and Southeast on Monday. As the storm moves northward late Monday into Tuesday, winter weather is possible from the Central Appalachians to Interior New England. Read More >

Winter officially ends at 4:24 pm CDT on Monday, March 20th, with the arrival of the vernal equinox and the start of spring in the Northern Hemisphere.

During the equinox, the geometric center of the Sun's disk crosses the Equator, and days in the Northern Hemisphere become longer than the nights. The word "equinox" is derived from the Latin word aequinoctium, meaning "equal night". However, despite common belief, the day of the equinox does not feature exactly 12 hours of daylight and darkness, as it is a function of solar refraction and an observer's latitude. The particular date of equal days and nights (referred to as "equilux") is actually a few days before the vernal equinox at our latitude.

Vernal equinox is 4:24 pm CDT Monday, March 20th
