A band of mostly light and spotty snow has stretched from eastern Virginia to southern New England this morning. The best chance for getting up to a few inches is in southeastern New England, especially Cape Cod. Lake-effect snow continues south of Buffalo and northeast of Syracuse. The wind will become more northwesterly across New York state tonight, and that favors snow south of Buffalo and right into Syracuse.
The cold will ease in the Middle Atlantic region as we go into the weekend, but gusty winds will erase the impact of any higher temperatures in New England.
The next storm looks like it will take the southern route across the Plains and into the Middle Atlantic states. If it reaches the D.C. to NYC corridor, I think snow is more likely than rain and greatest accumulation would occur if most of the precipitation comes on Sunday night. Here is today's video:
Last year at this time, temperatures were reaching the 70s and 80s from Chicago to Boston. Now it is 40-50 degrees colder and some areas are having snow.
This is how it looked from my front yard in central Pennsylvania with the last snowfall.
It is freezing cold in the Northeast this morning, but this map shows that much more mellow mildness has reached the Plains.
Extensive precipitation straddles both sides of the cold front that was moving through central New York and central Pennsylvania as of mid morning. This radar shows the distribution of rain and snow; some temperatures are added.
The cold front approaching the East shows up quite well in this pressure analysis. Several temperatures are plotted to give you a sense for how much the temperature changes behind the cold front. At Chicago, it went from 60 at 4 a.m. to 39 at 5:19, a 21-degree drop in little more than an hour.
Temperatures on Sunday and Monday will range from the 60s in parts of New England to near 80 in Maryland and Virginia. However, a strong cold front will then trigger and perhaps a few thunderstorms as it ushers in air that will be 30-40 degrees colder than it will be ahead of the cold front.
During the early morning hours of April 15, there will be a total lunar eclipse visible across North America. This eclipse is the start of a <em>tetrad</em>, a series of four total lunar eclipses over a two-year period. The totality begins at 3:07 a.m. ET, 2:07 a.m. CT, etc.
Severe Weather Awareness Week activities are conducted by National Weather Service offices nationwide at various times during the spring. There is a lot of information for everyone (from children to seniors) available online. You can start <a href="http://www.ready.gov/kids/know-the-facts">here</a>:
