But remember guys, you're just cold lovers and you're wishcasting. Only guys like Brett Anderson and the NWS are to be taken seriously.

Brett Anderson:



He is basically looking at the same models we are (albeit, knows how to interpret them better... I would hope)

The latest ECMWF model is not messing around and projects some serious cold!
The ECMWF map below shows the projected surface temperatures (C.) for 7 a.m. Thursday......

Sunday morning model runs continue to indicate the potential for a mid-week snow system here. Consistency's the word--both in terms of run to run continuity and in the disturbance tracks which are being put forth. Check out the following model snapshots verifying in the Wed midday & night time frame:

Weather Expert Bernie Rayno discusses the latest cold wave and the Thursday snowstorm in the Northeast.
Two storms will converge on the Northeast on Thursday with the potential for snow. How quickly they get together and strengthen will determine which areas are hit with heavy snow and which areas will have a near-miss.
The storm could have a major negative impact on travel for people returning from holiday destinations, heading back to school or resuming business activities.
People should be prepared for flight delays because direct and indirect impact of the storm. Flights destined to New York City, Philadelphia and other airports may be held up do to deicing activities in the Midwest and in New England.
While millions of people in New England are likely to be hit by the storm, the question is will an additional ten million people have to shovel out in the storm's wake Friday, including New York City and Philadelphia.
