Major storm likely to be more wet than white, this week

/by

A large, powerful storm system is expected to develop from the Mississippi River Valley into the Ohio Valley during the early to middle part of this upcoming week, as a significant phase in the mid levels of the atmosphere occurs. A strong low pressure system will drive northward through the aforementioned areas, allowing a deep southerly flow to draw warm, moist air toward our area during the middle part of the week. Initially there might be enough for cold air around for some frozen precipitation at the onset. But eventually warmer temperatures with periods of heavy rain, gusty winds, and possibly even thunder, will be possible as the storm impacts our area.

(Premium) Winter storm threat next week

/by

Forecast models continue to show a classic pattern progression across the Northern Hemisphere over the next several days, with a continuation of a wave progression that favors the development of a Western USA ridge and Eastern USA trough by the beginning of next week. The redevelopment of this large ridge in the Western USA, extending northward into British Columbia, is expected to be the focal point for the potential development of a storm system in the Eastern USA between February 24th and 28th.

Coldest air of winter to arrive this weekend

/by

A large arctic airmass, owing to a piece of the polar vortex, will drop southward late this week and weekend from Canada into the Great Lakes and Northeast United States. With it will come the coldest air of the winter — and the coldest air in quite some time, especially aloft. Temperatures at 850mb, or roughly 5000 feet, will drop to nearly -30 degrees celsius, challenging some records for temperatures at that level in the Northeast US for the date.

(Premium) Weekly outlook and hazards information

A powerful coastal storm will shift east/northeast this afternoon, toward the Northwestern Atlantic Ocean, with lingering impacts expected in our area. This will be especially true for coastal sections of Eastern Long Island, where bands of snow may linger until the evening hours of Monday as the coastal low pulls away. Elsewhere, relatively benign weather will take over with gusty winds in the wake of the storm system — but no further accumulating snow.

Despite the departing storm, there are several other weather events to speak about during the upcoming work week. They begin with a weak coastal storm from Tuesday into Wednesday, and end with bitter cold and a possible coastal storm threat this weekend.
