Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 226 PM EST Mon Jan 07 2019
Several lows will move from the Great Lakes into the northeast over the next few days, delivering precipitation region-wide. The first low will move from Wisconsin into western Quebec overnight, spreading precipitation eastward into the Northeast. A secondary low will arrive in the Great Lakes Tuesday morning, quickly move east, and then strengthen along the Northeast coast Tuesday Night and Wednesday. The passage of the two lows should cause temperatures to fluctuate from the Great Lakes into the Northeast, which may cause multiple changes in precipitation types in some areas. Much colder air should arrive behind the second low on Tuesday Night and Wednesday, leading to a final changeover to snow across much of the interior Northeast and lake effect snow in the Great Lakes. Significant snow accumulation is expected from Upstate New York into Vermont, New Hampshire and inland Maine, with over 8 inches of snow likely.
