Thursday Mid Day Update
Some in our region got snow yesterday, but many did not. So mentioning it again really is a matter of perspective. We are still in a winter pattern, and the unique impact across the Mid-Atlantic topography is on full display. The net result is heavy snow squalls in the mountains. There is some support to carry flurries or snow showers over the mountains. Meanwhile, the visible satellite is truly helping to show off the Fall Line and separation during normal winter events.
Let’s take a look:
The main storm is moving away through northern New England, but a disturbance in the Ohio Valley has plenty of cold and wind with it to produce snow showers. These have reached the mountains of Western Maryland. There may be enough energy aloft to help carry some of the snow showers or flurries into central Maryland.

The winds flowing UP the mountains reach the continental divide, and when there is moisture, will dump snow (or rain) along the way. As the winds flow down the lower elevations, the clouds begin to break up. Often the steady snow or rain ends at the ridges, but the clouds display the influence of the sinking air.
The net result are the ripples we see on the satellite display.
When there is more energy, the clouds can blend farther east, but eventually, those ripples indicate the diminishing moisture farther east and lower in elevation.
We see this on display today. Late this morning, the cloud line reached the Fall Line around Baltimore and I-95. More breaks of sun East and south, but more clouds to overcast farther west.

Thursday afternoon to Friday Afternoon.
This is the upper-level support that is causing the snow squalls and may help carry some bands over the mountains into central Maryland and southern PA. The net result could be occasional snow showers or squalls through this evening.
No local stickage is expected.
The snow squalls will be prominent in the mountains, where brief whiteouts and winds over 40 mph can create hyper-local blizzard conditions for a few minutes to half an hour or so.
Notice the attempt for the showers to carry east of the mountains.
This product is NOT Perfect and can often miss the lighter flurries.
One reason this impulse will fade this evening and tonight will be the winds. While they may gust 30 to 40 mph today, they are expected to diminish this evening.
