Periods of rain, some heavy, to soak the Capital Region through Friday night

Periods of rain, some heavy, to soak the Capital Region through Friday night, The second of three distinct waves of low pressure to impact the Capital Region this work week was southeast of the area early this morning, over the southern New England coast.

Rainfall that accompanied this latest disturbance was now well east of the area.

A lull in the precipitation looks to occur this morning before the final, and most potent, wave of low pressure impacts the Capital Region with more precipitation later this afternoon, overnight tonight, and into Friday.

The waves of low pressure were forming along a wavy stationary front that was draped from the New England coast, westward into the central Plains.

This frontal system is expected to remain just south of the region through tonight, before moving explosively north and east to be over the lower Great Lakes Friday morning.

Coastal low pressure looks to form by Friday evening over the New England coast as the inland low begins to weaken, and energy transfer occurs. The entire system, in all its complexity, moves northeastward and away from the area Friday evening.

The north country, Adirondacks, and Lake George Region, may see some sleet and freezing rain at times overnight tonight and first thing tomorrow.

Warmer air is then forecast to surge northward, in the low levels of the atmosphere, changing precipitation over to rain for the bulk of the day on Friday.

Conditions should start to slowly improve by Saturday. High pressure builds into the region during the day, however, a mix of sun and clouds looks to be the best we can do thanks to all the atmospheric debris (cloud cover and low level moisture) left over from the departing costal system, and the decaying low pressure area that was over the lower Great Lakes on Friday.

Areas to the north of the Capital Region may see a residual shower or two.

High pressure becomes the dominant feature in the region’s weather by the second half of the weekend, bringing sunny skies and a return to seasonable temperatures, before another week system approaches by midweek next week.
