Volatile spring weather has erupted, and it's leading to large contrasts in weather over distance and time in much of the country.
A series of storms will bring a brief surge of warmth into the East in the next three days, followed by a sharp downturn to much colder weather heading into the weekend.
Snow will fall from the central Appalachians to southern New England later tonight into tomorrow night, with more cold and no severe weather in the pattern later this weekend into next week.
Spring begins Friday evening, and at least half of the country will be warm in the next week, but it remains cold and even snow in parts of New England and the northern mid-Atlantic states.
Very warm weather covered the eastern Rockies and central and northern Plains yesterday, and it will spread eastward today ahead of a cold front. More spikes of warmth can be expected in the next couple of weeks.
The next storm coming out of the northern Gulf will be mainly a rain event, resulting in some flooding. It will remain through Monday before a cooler trend begins from the Midwest to the Northeast.
Much milder weather and an overall lack of snow will prevail in most of the country this week in contrast to last week's bitter cold and snow that gripped much of the nation east of the Rockies.
As the snow exits the East Coast tonight, extreme cold follows one more time. It will begin to ease this weekend, with a mild spell likely during the middle of next week.
After the storminess of the next 36 hours, and the extreme cold that immediately follows, the cold will ease this weekend, with a promise of milder weather next week.
