We continue today under the influence of a very cold high pressure, the same system that has being giving us unseasonably cold temperatures over the last week. In fact, yesterday, we experienced temperatures that are normal for the beginning of January rather than early December.
We will have a short break in the cold conditions, as the low level warm advection associated with the low pressure centered in Canada will take over much of the northeastern United States. This system, however, is too far off from New England to provide significant organization to the advected moisture. However, the passage of short waves might provide enough organization for bands of precipitation to form later today and tonight. Temperatures will be above freezing even near the surface, so rain and wet snow is expected.
Temperatures will come back to unseasonably cold after Sunday.
Tonight: Mostly cloudy with a chance of snow and sleet. Low 32°F (0°C).
Saturday: Mostly cloudy in the morning, then mostly sunny in the afternoon. High 44°F (7°C).
Sunday: Mostly cloudy, chance of mixed precipitation late in the evening. Low 29°F (-2°C). High 37°F (3°C).
