37 for the MBY low

[dailylurker]

38 in the lowlands. Coldest of the season so far. 

[GramaxRefugee]

Made 36 here. Yup, coldest so far.

ETA: minor frost on the usual rooftops, up the hill. Car thermo fell to 35 on the way in. Rather surprising.

[George BM]

Dulles got down to 33F.

First morning that I'm noticing frost on the cars.

[Interstate]

37.8 for the low here in 21057

[nw baltimore wx]

Some frosty spots this morning. At the very least, I need to invest in a min/max thermometer.

No frost on my car but some rooftop frost in my neighborhood 

[wxdude64]

2nd (barely) freeze of the season here, 31.4 low. Currently 32.0/30.7 at 8 am. 

[hstorm]

35 in Great Falls with light frost. 

[nj2va]

41 for the low. 

[IronTy]

40F right now at home in Calvert.  Game cam sent me a pic at 7am showing 33F at the cabin which is the coldest I've seen so far there too.  

[The Dude]

34 for the low here

[weatherCCB]

Low 35

[MN Transplant]

First morning in the 30s at 39.6.  Light frost in the favored lower elevation neighborhood spots.

[87storms]

Sunny start to the day here, but based on the satellite loop, the Catoctin crew should not get too comfortable with the blue skies.

[T. August]

Low of 38.6° here. First sub-40° this season. I do wonder if we can get a freeze in before the last week of November, which seems to be the first freeze now for the cities.

[Mrs.J]

Just got our first freeze warning for this fall. 

[WEATHER53]

35 for my low which is coldest of season

Couple of very, very early thoughts as we continue to slide through autumn:

1.) Seems like the Euro OP midrange QPF bias beyond HR 150 is real. 

2.) Long range warm ups may be head fakes. Also, as @mitchnick has observed it's good to see a persistent trough over Japan. 

3.) I have no expectations that we're going to see some SECS or HECS this winter, but man it'd be nice to get a forum wide 6" - 10" event.

This pattern would translate to a brutally cold, wall to wall winter.  Unfortunately, we’re kinda due for it.  Gotta get the outdoor activities in while I can.

Hit 32.0 exactly this morning for the first time... today has this raw winter post-FROPA kinda look to it, with gusty winds and the lower sun angle (and shorter days) casting plenty of cloud shadows and making them seem darker in the process. 
 

Definitely one of those afternoons where you can tell it'll be cold tonight! Freeze warning for all of Loudoun.. I'm usually about 3-5 degrees cooler than forecast so we'll see.

Due for it?! I got down to -2.4 degrees last year in Northern VA!  We had some brutally cold stretches last year (with absolutely ZERO precip.) Actually, wasn't that most of last winter? lol

Eh, I'm not sold on that yet. If we get a cold December then I think you're on to something, but we seem to have this post Thanksgiving / early December torch every year the resets things.

[mappy]

Not looking forward to playing softball tonight. It’s downright chilly outside 

[CAPE]

High of 58 after a low of 37. Nice Fall day with plenty of leaves falling in the wind.
