Winter Weather Advisory Cancelled In Maryland: Chilly Rain Continues Some Snow North

Sunday January 3 2021

The Winter Weather Advisory has been cancelled for Maryland and northern Virginia. The storm did arrive early as expected. So early, it did not allow the temperatures to drop low enough for many areas. Now we have that assistance from daylight for any areas that did get light icing.

 

 

So the frozen expectation did not work out, but I will mark this down as another example of systems arriving earlier than model guidance. That will come in handy with storms down the road.

We will have more chilly rain, and the second part of this system may try to end with snow just north of the border in PA.  Let’s take a look.

Morning Surface Weather Map

There are two forces just missing each other. We get the primary Low this morning, but another area of Low Pressure in Indiana will arrive this afternoon.  That will come with slightly colder air aloft, which could mix in some snow in southern PA.

 

Temperatures at Noon

Most of our region will be just above freezing, but still in the 30s.  The freezing temps will be found north of Harrisburg. If you plan to travel north on I-81 or northeast to the Poconos or metro NYC you might encounter some wintry weather.

There will be a break for a few hours this morning, then more chilly rain returns.

Watch for possible mixing with snow across southern PA mid afternoon.  Surface temps will be above freezing.

Looking Ahead

The next noteworthy weather event may be on Friday. I am still very skeptical of longer range model projections, but I will be watching this potential at the end of the week.
