Tuesday 9 a.m.
The high pressure area that promoted sunshine in the Northeast yesterday is moving east, and a weakening low pressure area from the western Great Lakes will move to the St. Lawrence Valley by tomorrow. Wet snow greeted the dawn in Chicago, but only spotty showers are likely in the I-95 corridor tonight (and many places will stay dry).
Temperatures will reach the 40s in much of northern New England tomorrow through Friday, with 50s in southern New England and 60s from about Philadelphia on south. A strong storm that could cause severe thunderstorms in the Gulf states Thursday will move northeastward to the eastern Great Lakes Friday. Last night's European model generated a very strong low pressure that would generate gale-force winds in the advancing cold air mass behind the storm. The GFS has a good-sized storm, but it never gets anywhere near as strong as on the other model. My idea is to take a compromise between the two and go for windy and colder this weekend... then not as cold early next week.
It is fascinating to see how many things in nature have the same appearance. Spiral galaxies in space resemble spiraling storm systems as they appear on satellite pictures. In this picture of waves in New York harbor, we see a resemblance to ripples that appear with altocumulus clouds overhead in the second picture.
The part of the front over the Eastern states will move south this afternoon and tonight, then a low pressure area will move along it. The result should be snow from the Ohio Valley into the Middle Atlantic states.
The thin blue line is temperature. Notice how it is left of the black line near the bottom, meaning the ground level temperature is below freezing. Several thousand feet overhead, however, it is warmer than 32 degrees, so any snow falling through that layer melts.
Today is the National Education Association's Read Aloud Day. If you have young children or grandchildren, I hope you get the chance to read to them today, and on many other days. On today's video, I tried reading to you.
The storm moving from the Ohio Valley to the Middle Atlantic coast will cause snow and ice, Clearing should follow tomorrow, but another storm should bring snow and ice followed by rain from Maryland to Massachusetts.
Clearing should follow tomorrow, but another storm will cause snow and ice followed by rain from Maryland to Massachusetts late Tuesday into early Wednesday.
The wind will not roar like a lion in the Northeast on Sunday March 1. It certainly won't be lamblike. However, with more cold and snow in the forecast, it might be suitable for this group:
