I think we get5-6 hours of sleet and snow that tapers to drizzle and is not 0.35”+ of freezing rain. Then by late Thursday afternoon all rain for everyone even 25+ miles north and west of DC
39 at 4:15 down 2F from the high of 41 at 3:15
Dews not coming up and baro not relenting and thin cloud cover not preventing temp drop off. Lower and thicker clouds look 1-2 hours away
i think us Obs Warriors will have something to work on!
Millville and any others-
when West of I-95 is referenced can you clarify that metric further? I am 5 miles west, is that too close or does it mean literally west if 95 period or 10-15 miles or more?
thanks
also-just hit 40 with dp 20.
Looks like when we get to 85%+ rh temp will evap to 30 so that’s dicey. The high is not in a good location but it is quite strong and not moving. As I said yesterday it’s an In situ and to me it appeared snow and sleet would dominate. Real big freezing rain storms are rare around here, about every 15 years yet there are modeled 1-3 times every winter.
I’m going to predict the cloud increasing holds off until 7/8pm Wednesday. By then DCA temps and dewpoints I think will be 37/20 and if we can get precip that is not real light but closer to light-moderate then by midnight-2am DCA should be 30/28 and it’s going to be worth watching
Very strong low pressure to west and very strong high pressure to the north-northeast and neither moving much at all.
This looks like a long period of overrunning with the warm air being very slow to takeover, probably not until dark Thursday. If there is enough moisture we get a sleet and snow combo for over 10 hours. But it could be too light and just drizzle. The B transfer just looks like the transfer is very slow to materialize
interesting in situ for the obs thread.
I would disagree experientially that “even in our best patterns we often need multiple chances before we get a hit”
In our best patterns it snows just about every time it can . When we are speaking of multiple misses beforehand we are mostly In trouble
Models frequently show a positive outcome from a Miller B for DC area. They are almost always wrong as it generally develops too far northeast and maybe Baltimore gets a little, northeast MD more, Philly to NYC a lot.
I commented earlier in the winter outlook that this winter would not behave Nina like. I looked back to 1980 and could not find an exact match to what you asked

Probably should have been in hospital for 5 days, then moderate-serious 5 days, then moderating over next 7 days and on 7th day went out and ate heartily , One week later everything closed.
One excellent solution to maintain reality is do not consider anything beyond 5 days as a forecast. When a 1040 high in the right place is represented in the 5 day or less then we have something. When it’s shown in the 7-15 day it’s useless. .
