Several days of above normal temperatures are giving way to a return to cold this week, with snow expected Wednesday, but not much of it, forecasters say.

Monday's temperatures in the mid-to-upper 30s will likely be the warmest seen this week, said Tim Morrin, National Weather Service meteorologist in Upton. The rest of the week will zig-zag between highs in the low 30s and high 20s, he said.

A small amount of light snow, a possible 1 to 2 inches, is expected to fall from before sunrise through around lunchtime Wednesday, meaning "a little coating" and "some impact" for the morning commute, he said. With this "quick-moving, moisture-starved system," snow amounts would be more likely to lessen, rather than increase, should the forecast change, he said.

As for the cold, Tuesday's high and low are expected to be 29 and 18; Wednesday's, 31 and 11; Thursday's, 32 and 13; and Friday's, 27 and 18, with the cold continuing into the weekend, he said. Normal highs for this time of year are 42 to 43.

The "silver lining" to this weather pattern, which finds an upper-level disturbance parking over eastern Canada, is that it doesn't "support a big, high-impact snowstorm" this week, Morrin said.
