Monday November 16 2020
The wind storm and cold front that blew through last night resulted in over 70 reports of damage. It has also opened up the weather pattern to shift back to reality, with even colder air on the way.
Snow showers will fall in the mountains and flurries could reach parts of central Maryland.southern PA. Then the first freeze of the season for Baltimore at BWI could be the latest on record.
Morning Surface Weather
It is already chilly this morning, and the breeze will be noticeable today. But even colder air on the way with a disturbance tomorrow into Wednesday.
The peak winds will be mid morning to early afternoon. Most of the region will see top gusts up to 25 mph.
Just cool today. It will be turning even colder.
There could be frost and freeze inland, but the urban freeze will be a day later.
Push of Colder Air
The first coating and accumulation in the western mountains of Maryland is finally going to happen. Snow showers may also push east of the mountains in southern PA.
While not shown on the map here, I believe flurries will fly in parts of central Maryland as well….
Upper Level Air
This plot shows the energy at 500mb (18,000 Ft) aloft. This set up brings the fastest winds and spin across central Virginia. That is a prime location to allow any Lake Effect Snow Showers to cross the mountains and reach the suburbs and perhaps metro areas.
No stickage expected, but flying snowflakes could surprise some people.
I’ve added ‘Flurries’ with a ? because it’s not a promise and mainly for ambience. The cold air is the big story, and this forecast is for central Maryland.
Freezing Temps likely Wednesday and Thursday mornings.
Is this the latest Freeze for Baltimore?
I’ve looked back in the past 5 decades for the latest freeze and found these dates:
- November 16 in 1972
- November 13 in 1986
- November 12 in 1994
- November 9 in 2004
- November 8 in 2007
- November 8 in 1984
It’s been hard to look at specific dates farther back, so until I can confirm, this will be considered with that caveat: Latest first freeze in at least 50 years.
Needless to say, more than 90% of dates with the First Freeze in Baltimore at BWI are before.
The average First Freeze is October 29th.
Two mornings with expected freezing temperatures at BWI will be Wednesday and Thursday.
Another warm up for next weekend, then back to reality next week into Thanksgiving.
