Forecast for Monday, July 9, 2012


A cold front continues to slowly push southward. As of late this afternoon, the front was draped across Maryland and Delaware. A severe thunderstorm watch is in effect for Kent and Sussex Counties in Delaware. Thus far, most of the severe thunderstorms are in Virginia and West Virginia with some thunderstorms into Maryland. Again today, there is CIN across our region and this is limiting convection development at this moment in Delaware. However, very humid and hot conditions could break the cap in place by early evening, but this is once again a wait and see situation. Should the cap burst, there will likely be rapid thunderstorm development with access to plenty of instability and moisture. Further north, there is a secondary cold front moving in from the northwest. Here, little CIN can be found. However, drier air behind the initial front is going to most likely limit activity developing along the second boundary. There is a real slight chance at this time something could fire up.

For late tonight into Monday, the main front will become stationary and slowly weaken. South and along this boundary, there still could be a slight chance for a shower or thunderstorm as waves of energy move along the front. Meanwhile, sunny and comfortable conditions are expected the further north one lives or travels across the area with Philadelphia in-between with variable cloudiness expected.


Later this week, this front may lift northward as a warm front. There are many questions as to how far north it lifts and whether it will contain any substantial waves of energy to bring in showers or thunderstorms. This obviously creates issues with trying to come up with a temperature forecast for Philadelphia as much hotter air with humid conditions will lie just south of the front.
