Downpours Thunderstorms Moving Through Today

Looking at the satellite loop this morning we can see the north south line of clouds as we have a cold front stalled along the coast. Ripples along that front are producing showers and some thunderstorms with some locally heavy downpours. This will continue on and off throughout the day. Notice that the clouds are moving south to north along the East Coast which is a signature of what happens when fronts stall out. Once the last wave passes overnight weather conditions will finally being to improve. Temperatures today will settle in the upper 60s and lower 70s and without any sunshine that is pretty much where they will sit all day.
