Record warmth remains the top story this year as a strong low pressure system in the great lakes opens up the flood gates for deep southwesterly flow Tonight through Christmas eve night.
Upper Level: A negatively tilted trough is moving through the central plains. A ridge is positioned over the east coast of the US. The trough will lift up to the great lakes region during the next 24 hours. The jet stream will continue to sit just north of region into the end of this week. The 500mb pattern becomes zonal in the east this weekend.
Surface: Developing low pressure is moving northeastward across the plains. Out ahead, a warm front sits just to our south. It is expected to lift north tonight with strong high pressure anchored off the east coast and the deep low tracking up through the great lakes and then into Canada. A weakening cold front approaches Christmas eve night and will likely dissipate on approach. Record warm weather is possible for both christmas eve and christmas day. Things turn cooler by Saturday as winds transition back onshore with a departing high. Developing low pressure in the deep south approaches new England this weekend and will help to push a warm front back north Saturday night. There is a renewed chance for showers during the period. An active weather pattern continues into the beginning of next week where more unsettled weather looms – perhaps including some snowflakes for interior southern New England: stay tuned.
