Yesterday's blizzard across the southern Plains has headed northeast towards the Great Lakes region and places like Chicago and Detroit will be its newest victims with respect to heavy snowfall amounts. A secondary low will form near the east coast this morning and this will send rain our way later today continuing in the overnight hours and some of the rain will fall heavily at times. The entire I-95 corridor between DC and NYC will likely receive 0.75-1.75 inches of rain from this system by early tomorrow. In upstate Pennsylvania, there can be accumulating snow and ice later today in higher elevation locations such as in the Poconos. After a mild day on Wednesday, an upper level trough of low pressure will take up residence near the east coast and bring unseasonably chilly weather to the eastern states for several days all the way from the Mid-Atlantic region to central Florida by the weekend. The trend downward in temperatures in the Mid-Atlantic will begin Wednesday night and Thursday and there can be a few rain or snow showers in the unstable atmosphere.
