Looks like another real taste of fall next week... LWX has highs near 60 on Tuesday in DC metro with lows in the mid 40s... looks like lows in the upper 30s possible Monday night out towards i81 corridor and west

Fun model confusion for Sunday. All 12z models went north except euro ai, which went back south. Op euro has 2” to the south side of 495.

The WPC is tossing the physics models and buying ECM AI and GFS AI.

This will be very interesting!!

The EURO AI ensembles/GFS ensembles and Euro ensembles dont seem too impressed

here is the 50 percentile which actually went south from 6z

The Graf predicts nearly an inch of rain over the weekend.

This one probably isn't for us. It looked that way last night when I made a couple posts about it. Not much change 24 hours later.  I'm not mad about it at all, but there will probably be enough moisture to be annoying here. I'll take the clouds but give me a dry weekend.

Totally agree.  I'm not mad about "missing" anything either, at this time of year.  And personally, I would like it if at least Saturday can be fairly decent.  It's kind of looking as if any rain will mostly be like a Saturday night into Sunday night deal at this point, from what I've looked at?  (Depending on how that frontal wave develops, etc.)
