Discussion
A major pattern change is going to take place next week in the Mid-Atlantic region that will result in a sustained period of colder-than-normal temperatures. This change to sustained cold in the Mid-Atlantic region will be the result of a combination of strong high-latitude blocking (i.e., nearly stationary strong high pressure over Greenland and northern Canada), an intensifying upper-level trough in the central and eastern US, and strong high pressure ridging along the west coasts of Canada and the US. The strong cold front that will begin the pattern change to cold will arrive with showers on Tuesday night and Wednesday and then colder air will pour into the region later Wednesday into Thursday.
