February 27, 2012 Technical Discussion
Synopsis:
A weak cold front will pass through Monday to start off the week. High pressure will then settle in Tuesday and most of Wednesday. A low pressure system approaches the Commonwealth which will affect the area for the remaining portion of the work week. There will be a good chance of a wintery mix during this time frame as the freezing line fluctuates north and south of Pennsylvania.
Short Term:
As a short wave through moves northeast out of Pennsylvania, a high pressure system will make its way in for the early portion of this week as a system develops to our west. Furthermore, sunny skies will result Monday and Tuesday from this high pressure with mild temperatures in the upper 50's.
Long Term:
Good lake effect conditions will be present as a low pressure system begins to make its way to the commonwealth. The northwestern portion of the state will receive the hardest hit resulting from lake effect snow and upward sloping snow showers. As the 540 thickness contour moves north and south through Wednesday night and Thursday, a wintery mix is likely for this time frame. As for the weekend, the same pattern will repeat itself as high pressure comes back over the State as another low develops to the west.
