We have a very wet and unstable weather pattern setting up for much of this week.  Thunderstorms, some severe, are possible most days of the upcoming week.

Right now (Monday early evening), a severe line of thunderstorms is affecting Washington DC.  (Possibly adding more water to the “swamp” there.)

In all seriousness, the storms approaching DC are extremely fast moving (excess of 60 mph), appear as a ‘bow echo’ but almost take the form of something called a derecho.   I don’t usually focus on weather outside the PHL area, but this radar image is impressive, with likely tornados.   We may have similar weather late tomorrow afternoon.
