    Milder until Friday, then Colder

    February 21, 2012; 7:29 AM ET

    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.

      On the map, one band of rain is along the coast at the north edge of the picture, the second is entering the Sierra range straight east of San Francisco, and the third extends from Los Angeles northeast to Las Vegas and on from there.

    • Northeast: Warm through tomorrow then cooler and wetter

      October 18, 2016; 10:40 AM ET

      In eastern New England, an onshore flow of cool damp air prevailed all morning. There could be a last-minute warmup this afternoon. The affected areas will certainly be warmer tomrrow morning than they were this morning.
