It's back!  The humidity and chances of thunderstorms will greet the D.C. region the rest of the week and right through the holiday weekend.  We really have to look at the upper atmosphere to understand what is going on.  There is a dip in the jetstream in the eastern U.S. that will keep us slightly cooler than average and unstable.  Disturbances will ride along the jet and bring showers and thunderstorms off and on.  Today and Thursday look most likely to get stormy with lesser chances tomorrow and this weekend. Any thunderstorms that develop this afternoon/evening could become severe. There is a slight risk of damaging winds in storms, especially between 3p and 8p.  We have to keep an eye on cloud cover today that could limit heating and instability. The more sun we get, the more likely storms will be strong later.  This evening the clouds could inhibit the viewing of a conjunction between Venus and Jupiter.

Conjunction of Venus and Jupiter

The two planets will be within 1/3rd of a degree of each other in the Western Sky this evening. They may appear to be colliding.  You'll see them all week long after sunset, but tonight they will be closest together. It is expected to be the best viewing in more than a decade if skies cooperate. (about a 60% chance it won't). Lower rain chances Wednesday and this weekend. Only a 20% chance that rain will interfere with the fireworks on the Fourth of July.  Have a great day!
