Wind Chill Watch/Advisory/Warning is a long standing product. Prior to today, here is the last time and wind chill product was issued by LWX:

52 in Westminster, 38 in Thurmont. Impressive gradient.

Check out that coastal front. Probably reinforcing the wedge a bit west of I-95.

Meso models are absolutely insistently on a core of 925/850 winds hitting Baltimore region around 12z to 15z. Even BUFKIT has some 70 - 90kt winds just off the deck tomorrow morning.

RTMA analysis shows a temp of 32 in Indianapolis, IN, and 14 in Gary, IN.

The most recently issued product is what is visible "on top". It's like layers on a sandwich. When the "top" product expires, then whatever is "underneath" becomes visible. For example: If NWS issues a Flood Watch at 10:00 am, then a Wind Advisory at 11:00 am, then Wind Advisory becomes visible on the WFO home page. This becomes messy during complicated, changeable storms like the one we are experiencing now, and NWS is aware of this. I've been on a few webinars and completed a few surveys about some possible changes to their interface, and what's potentially coming down the line looks good. I don't know anything else about the nitty gritty.

I tell ya, we get a solid 20 - 40 min of snow as things chill, definitely could see a cluster on the roads. Can't salt anything because of the rain.

@Ralph Wiggum, your coveted FreezinG Spray Advisory! https://forecast.weather.gov/wwamap/wwatxtget.php?cwa=LWX&wwa=freezing spray advisory

Wind Chill Advisory coming out for DC/Baltimore metros. Should populate on NWS website shortly.

Can we please take the bickering to the banter thread?

Yea that front is legit. It's rare to experience temp drops like this east of the Mississippi so it's going to be neat to see. Hopefully we can mange an inch of snow with this flip. Might help us really bottom out. That's seriously amazing. That's some John Muir level of outdoorsmanship.

Definitely some wet snow mixing in here in New Windsor.

Western folks, please keep these snow pictures coming. I hope you jackpot!

IP/SN mix in New Windsor for about 30 min, then sleet and drizzle. Temp 35/29.

Starting to think this might be a legit cold front coming out way.

Nice

Time to move to a more interesting climate.

This cold push seems legit.

Oh, nice

12z Euro/NAM/GFS seems insistent on some little 925/850 wind maximum hitting Baltimore some time between 12z and 18z Friday. Even GFS BUKFIT has some decent winds mixing down to the surface.

Both the NAM and GFS have some insane frontogenetic forcing with this fropa tomorrow. Probably going to see a few snow squall warnings as this thing rips through.

The Feb 2006 storm was indeed a thread-the-needle event. I was at Millersville at the time and remember we scored a few narrow hits that left DC with rain. For the Feb 2006 event, we were supposed to be cloudy with a midday start time, but we woke up to full sun and temps in the mid 30s. Thankfully we narrowly lucked out up there, but I agree, today that storm would be a cold rain. Our climate is broken.
