I'm WSA 9 meteorologist Topper shot.
Hey this could be our biggest snowfall
in over three years especially
DC South and East. Yes white
that is. That is the winter storm
warning and discovers Montgomery
County and Fairfax and points South.
Kind of counterintuitive.
So up to the north.
Only an advisory which means less snow.
1:00 AM on Monday at 4:00 PM on Monday.
So snowfall the next two days.
These numbers are eye popping,
11 inches, graph 7 inches,
Nam over a foot for the GFS gem coming in at.
7 inches,
even the European come in at 10 inches.
Now here's the thing I'm gonna
show you a lot of maps after this.
I'll show you the map
form of all those graphs.
But that's if every flake
fell in every flake counted.
I just don't think that's going to happen.
Not taking into account our
temperatures in the 60s.
How warm it's been the warm ground when
I was walking at the paper yesterday
and they were nightcrawlers on the driveway.
I mean, the grounds,
not even frozen,
not cold at all.
And that will cut down accumulations.
Can it overcome that?
Yes, but here's what we're thinking.
We're thinking essentially 4 to
6 inches DC and South.
The bullseye is Southern Maryland.
Hey you folks in Calvert County Saint Mary's
County might be in the Bullseye 2 to 4.
Sadie's Elysburg Gaithersburg Silver
Spring Bethesda and then as you go north,
yes, you get less snow.
Counter intuitive one to two inches
and that one to two inch band is
probably too far into Pennsylvania.
There's going to be a pretty sharp
cut off as we go through this storm,
and we're going to see again
over 6 inches in the Delmarva.
That's a big storm for them all, right?
So overnight rain changes to snow
after midnight loads above freezing.
No problems or roadways.
Overnight problems become Monday
morning as temps go below freezing.
An inch to the north,
6 inches to the South.
Snow heavy at times there's going
to be some heavy bands of snow.
Pretty impressive and that will
help overcome the melting.
So snowy and cold to the bus stop.
If you have school and then plan on a wet,
slick slow commute home so it will affect.
I think both commutes, but it won't
be snowing on the way home by to work.
It will be by afternoon snow ends,
but again slick spots for the ride.
Home temps below freezing
and then Monday night.
It's cold.
We're gonna have slick
spots all over the place.
Be careful walking too.
18 to 26.
That's one of our colder nights with
temps in the teens in the burbs.
Alright, so 11:00 o'clock tonight.
Rain South.
Notice the temps already in the 40s.
It's pretty serious.
Cold air with this by 4:00 AM we
have snow across most of the DMV.
The darker areas of blue is
the heavier bands of snow.
By 7:00 o'clock pretty good snow
going across the entire metro area,
even into Southern Maryland.
Now with temperatures critical 35
production River 33 Fredericksburg
by 10:00 o'clock notice.
Fredericksburg is already below freezing
already below freezing at Andrews so.
But also notice the snow shut off.
Now Martinsburg, Hagerstown and then by
two o'clock snow is shut off except for
maybe Calvert County Southern Maryland.
That's it already clearing back to the West,
but temps still right around freezing.
Not really going to rebound much.
It's going to stay frozen.
As we go through the afternoon,
then certainly tomorrow night,
temps in the 20s by 9:00 o'clock
and in the teens eventually.
So that map we just showed you.
This is a numerical output.
11 inches DC.
Don't see it 6 inches as far
north as Frederick.
Don't see it.
13 in Fredericksburg could see that
maybe and then 14 in La Plata.
Don't see that there's
going to be some folks.
I think they do get a foot of snow
with this particular system now.
Let's run through some other maps.
This is the her this I kinda like
me because it's closer to my map,
but I kind of like this 5 inches DC
3 inches Gaithersburg 8IN laplata
almost nine in Fredericksburg.
Very little Hagerstown 0.3 in
Martinsburg and there's going to be a
very sharp line of demarcation between
significant snow and heavy snow.
All right the Nam.
This is not bad either.
Nothing in Frederick it's a little further
South that has 8 inches in DC and 11
in Laplata and 11 in Fredericksburg.
You do see a pattern here.
I mean all the models are saying hey
the bullseye is South and east of DC.
This is the European model has 10 in DC.
Almost five in Frederick.
12 in Fredericksburg 13 in La Plata.
Little further north with the European
model and I will give you one more.
This is the GFS model and this
does carry snow across the border.
I think that's too far north.
Gives us 13 inches.
Don't think that's going to happen.
15 in Fredericksburg and 16 in Laplata
so This is why we pull our hair
out when get to a snowstorm because
the models are not in agreement.
Yes they all say it's going to
be DC South and east,
but then you gotta factor in a
warm ground and also the melting.
But all that said.
If you can't stay off the roads
on Monday morning,
I would recommend it because the
heavy bands of Snow will overcome
that melting and roads become
slushy very quickly.
That will turn to ice by Monday evening.
