Tuesday Afternoon Update January 7 2020
Finally! We have snow to quiet the doubters and I am back online for an update on this website. The forecast was updated this morning on social media during my latest web glitch. I am including that with others to compare here. Now that my latest web glitch is fixed (thanks Yoni Sapir) let’s get to business.
Headlines:
- Snow will fall while surface temps are above freezing
- Inland areas will get stickage sooner.
- Snowfall burst can reach rates up to 1 inch per hour for a few hours
- Road problems begin between 3 PM and 4 PM through dark in the colder inland suburbs west and north of Washington and Baltimore
- Total snow wil be higher on the grass (1 to 3 inches in the colder zone)
- Urban areas will have snow on the grass, but wet roads could turn slushy after 6 PM
- Freezing possible overnight for wet untreated pavement
I was driving on I-83 at 1:30 PM and saw the snow begin to fall while temps were 41ºF. The clouds are that much colder, but still the warmer ground is the battle for what can stick and pile up. But a burst of snow has been advertised by me, others, and modeling. This is what NOAA posted recently:
Snow Burst:
Rates up to 1 inch per hour! This was the update from NOAA’s Storm Prediction Center for our region between 2 PM and 4 PM. Let’s take a look at the radar, simulations, and forecasts below:
Winter Weather Advisory
Snow is likely through this evening. Schools have closed early and those that didn’t in the snow zone have canceled evening activities.
First will be the conditions at 2 PM, them compare the radar to the Radar Simulation from the NAM 3 KM Model. My snow forecast increased just a little since last night, but we still need to account for melting on warm pavement vs. the bursts of snow.
Temperatures
Radar Loop (non winter model) Up To 2:05 PM
Radar Snapshot at 2 PM

It does appear that the snow has filled in faster than the modeling suggested.
