Yup.  I can see that.  Once again I blew the contest.  I should have remembered that old saying ...cold September..no freeze til November.

00z GGEM still likes 31 degrees at DCA and 29 at BWI 12z Saturday morning... 00z GFS/00z UKIE both say no though with upper 30s as lows

ETA: 00z RGEM at its final frame at 12z SAT has DCA at 32 and BWI at 30

Martinsburg has a chance for a couple of sub-50 high temperatures on Friday and Saturday.  They've already had one this month at the airport.  The last time MRB had more than one sub-50 high in October was 2012, during Sandy.  The last time there were more than two days that cool in October was 2009.  Coupled with the earliest freezing temp on record in September, its been a nice cool start to autumn.

this week has been terrible. cloudy. gray. foggy. terrible for ones mood. 

next two days dont look much better.

I totally agree. I work in a health care setting and it is bad enough already with the backdrop of Covid and limitations on activities in the more at risk populations, but add on this lack of sunshine, with shorter days and the chill coming, it certainly is draining on one's mental health.

Load up on D3 supplements, CBD oil, and drink moderately if possible.

2020 ain't so bad. :drunk:

And I've been taking D1,D2,D4 all this time ... oh the humanity :axe:

LOL

Well, vitamin D3 comes from fish oil, egg yolks, etc. When skin is exposed to sunlight, it produces vitamin D3. So for those lacking(or avoiding) sun exposure, it is the one you want. Lack of D3 can cause depression in some.. i.e SAD. Most people in the mid and higher latitudes are deficient, unless you are a sun worshipper.

LR uncertainty. We know all about that.

Ensembles have been advertising a cold period sometime around Halloween for quite awhile now. It is going to happen. Always issues with timing and details..

Yeah. Just hammering home the point that cold is notoriously slow to come east in Ninas and that nobody should put stock in any model at
10 +. In case anyone needs reminding ...

Both NAMs and GFS painting a very widespread 2”+ for just about everyone.  Below is euro precip from last night.

Couple of very raw days on tap.

That's a thin band with good rain. And, sometimes it shifts down or up this far out. 

I only say this because I am hoping for less rain.

LWX AFD mentions 30s and 40s for highs on Monday with poss advisory criteria winds... so it going to be a chilly day

Quote

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
A powerful cold front will be approaching from the west on
Sunday, but will not arrive until Sunday night. Thus, we will
see a mild southwest flow which should allow temps to moderate
significantly compared to Saturday`s chilly temps, with a rise
of 10 or more degrees possible. This, however, would only bring
temps back to near normal.

The front will cross the region late Sunday into Sunday evening,
with some showers along or just behind the front possible. Will
have to watch for potential low-topped convection, as well as
for a burst of gusty winds behind such a powerful front.
Gradient winds will be strong behind the front, particularly on
Monday as low pressure strengthens to our northeast, providing a
windy and chilly start to the work week. Humidity will also be
low, and if it wasn`t for the rains we will get today, there
could be a fire weather concern. Winds could approach advisory
criteria on Monday, which might cause minor damage, mainly to
trees.

Temps Monday will be well below Sunday, and in fact stand a good
chance of being the coldest so far this season, with temps
potentially staying in the 30s and 40s all day long. This would
lead to another widespread freeze potential, with likely
the coldest night of the season thus far Monday night. Temps in
most suburbs could reach the 20s, especially if the wind
slackens late at night.
