Spring Training?

By Marek Zebrowski
Staff Meteorologist

After a few frigid weeks this weekend's slightly warmer than normal temperatures will seem like a spring preview indeed. All this thanks to a more zonal (west-to east) flow in upper levels, which will keep cold air trapped in Canada and a high pressure in the East that will allow an ever stronger February sun to warm the airmass to a more comfortable levels.

Later in the weekend our attention will shift to the south: There, along a stationary front extending from the Florida panhandle to the Carolina capes, a fairly vigorous and moisture-laden low will develop. This system, redeveloping near Cape Hatteras on Monday, is likely to interact with a northern stream energy dropping out of the northern Great Lakes late Sunday and could be a significant weather-maker as it is forecast to race toward Newfoundland along the New England coast. Colder weather will follow in its wake for the middle of next week.

Today: Mostly sunny and pleasant with moderate westerly winds. High 43F (6C)

Tonight: Clear and chilly, with lows around 28F (-2C) in the city and lower 20s (-6 to -4C) in the suburbs.

Saturday: Mostly sunny with clouds increasing in the afternoon. Highs around 44F (7C) may drop to the high 30s (34C) along the coast with afternoon seabreezes developing.

Sunday: Mostly cloudy and cooler with highs near 40F (4C) and lows in the 20s to low 30s (-4 to 0C).
