A southwesterly flow of warm, moist air ahead of a cold front is contributing to a band of rain and thunderstorms that stretches from the Ohio Valley into parts of the Middle and North Atlantic states. We expect some showers and thunderstorms to cross the I95 corridor from D.C. to Boston later today and this evening.
The cold front should slip south then stall from Virginia or Maryland to Kentucky tomorrow. With the front likely to make only limited progress, some additional showers may occur tomorrow from D.C. to New York City and on west. Most of New England should turn sunny.
In general, computer models suggest a low pressure area forms along the front in the Middle Atlantic states on Friday then slowly moves up along the coast this weekend. If that happens, it will be a damp weekend in the I95 corridor of the Northeast.
In contrast, most of the Great Lakes region looks like it will bask in sunshine with afternoon temperatures in Detroit and Chicago close to 70 and nights cooling to the 40s and 50s. The video has more.
In the longer range, the re-curving of the latest western Pacific typhoon may signal an upper air trough (and cool weather) in the Northeast in a week to 10 days.
Late September is not generally known for widespread thunderstorms, but this map shows near 50,000 lightning strokes in the period from 8 EDT last night until just after 8:30 EDT this morning.
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:
The surface analysis shows to low pressure area off the North Carolina coast, a large cold high pressure area in the northwest corner of the map, and a broad northeasterly flow of cold air between pressure centers. Cold will continue in this whole area through Saturday.
