Thursday March 9 – I am down with more snow sticking on the ground, at least in the normally colder zones. I know this may seem odd as temperatures have reached the 70s today. I need to be clear that it will snow tomorrow AND many roads will be wet. BUT, the intensity and timing, along with a stronger push of colder air… will allow for more stickage north and west of the city. So if there are travel and school issues tomorrow, that may be in southern PA, and in northern Maryland counties of Frederick, Carroll, northern Baltimore, northern Harford, and western Howard and Montgomery. The typically colder spots. There will be snow falling during the morning and mid day farther south and east across Delmarva. At that time the higher sun angle and warmer temps should limit stockage to grassy areas and lower amounts.
I know this sounds familiar. We did this drill on February 8 to 9 with a warm day followed by a brief snowfall the next morning. I show maps from that storm in many of my school assemblies. The difference this time is a stronger event and a longer duration of moderate snow in the morning… The ground is warm, but the last event has only an hour or two of snow in many places. This time we may have a half a day of snow. But the issues of any stickage diminish after 9 or 10 AM with a higher sun angle. Here are the maps…. including my adjusted snowfall map and the outlook to a coastal storm next Tuesday
