Weather: Danger: Don't Feed the Weather

By Greg Lawson
Staff Meteorologist

Only 18 of the 48 contiguous states did not have some officially issued weather warning as of last night, an unheard of statistic. The warnings include flood and severe thunderstorm warnings in the southern mid-west, strong wind warnings in the northern mid-west, and winter storm warnings for most areas west of the Mississippi. Luckily, Massachusetts has managed to avoid all of these. The warnings are tied to an extremely strong low pressure center raging across the country and an impending cold frontal cyclone from off the Pacific.

The strong low is a real beast. It is currently over the Wisconsin and Great Lakes area. Its minimum pressure is 967 mb, lower than many hurricanes ever get. Also, its winds may very well reach hurricane strength. It is carrying lots of heavy, wet snow and is leading a very cold air mass. This storm may be stronger than one that struck 23 years ago to the day which followed a similar path with similar strength and ended up sinking a large carrier in Lake Superior.

When something this large screams through the country, we are inevitably going to get hit by it. We may manage to miss out on rain tonight associated with the warm front, but there is no chance of missing out on the cold/occluded front - there will be simultaneous rain over almost the entire east coast on Wednesday! Expect rain to begin late this evening. It will begin with light showers and continue to strengthen throughout the night. The clearing will begin Wednesday afternoon. Once all has passed we will be left with mild temperatures and some clouds for several days.

Today: Clear giving way to clouds. Winds begin to pick up. High 48F (9C).

Tonight: Rain beginning before midnight. Showers through the night. Windy. Low will be a mild 46F (8C).

Wednesday: Continued showers through to the afternoon. Winds, clouds and mild temperatures to persist. High around 60F (16C).

Thursday Outlook: Cloudy. Winds eventually dying down. High in the mid 50s (12-13C).
