Sunday Morning Snow Update February 7

Sunday February 7 2021 at 9:45 AM

I know there were doubters, but the snow has taken over for most of our region. The transition may have been an hour or two later in the city areas, but still able to overtake the warmer pavement.

Doppler Radar Snapshot

I wanted to compare the standard mode to the winter precip mode.

On the left, the yellow shade indicated snow rates of 1 to 2 inches per hour. This has allowed the quick ‘thump’ of accumulation expected.

As of this post, Frederick has reported 3 to 4 inches of snow. The rest of the western suburbs have over 2 inches and still coming down. Stickage taking over in city and I-95 areas, but right along the water might still be a battle.

Important Notes:

Heavy snow will wind down and begin to move out around noon.
When precip is lighter, it may turn back to rain. *The heavy precipitation has been dragging down colder air.
Afternoon clearing: Time to thaw and clear roads
Evening Refreeze: What is still wet around sunset will ice up

Temperatures

Still marginal temps, but most will thaw/melt as soon as the snow stops.

Atmospheric Memory

Low Pressure off of VA beach followed a path similar to our last storm this past week.

SNOW Forecast:

The one mistake I made (for some) was lowering the snow forecast last night in my final pre storm report. We can compare after this ends.

It’s funny though, some people suggested I would not post a Grade My Forecast before it changed over. I hope they chime in at the end.

How Much Longer?

NAM 3 KM: Suggesting more mixing by the water. Also this may end with rain as the intensity decreases. This should end between Noon to 2 PM for most areas.
