The relatively minor cold spell we’ve had this week transitions into a dramatic warm up going into the weekend. Above normal temperatures will persist into the beginning of next week before moderating later in the week. We have a chance for a soaking rain beginning Monday night going into Tuesday.

Rest of today – partly sunny with some gradual clearing later. High temperatures in the upper-30s to around 40ºF.

Saturday – much warmer due to a dramatic shift in the jet stream with high temperatures around 50ºF with warm air rushing in from the south and west ahead of a frontal boundary. The polar jet that’s brought a return of cold air to the region will be pushed considerably further north of us with high pressure building to the southwest. This is a setup favoring much warmer air flowing in from the south and west.

Sunday – a backdoor cold front will sweep in from the northeast, bringing cooler, more moist air from the Canadian Maritimes, leading to high temperatures in the mid-40s. Mostly sunny.

Monday – cloudy with a high in the low-40s and increasing chances of rain as a vigorous low pressure system approaches from the southwest.
