First Snowflake Prediction for Feb 20, 2019

There is a winter storm watch in effect for all of MoCo. The watch states that snow totals of 5 inches or more are possible and the ice amounts will range from 0.1-0.25 inches which can easily cause power outages and slick roads. It also says more than 0.25 inches are possible. This is a moderate storm(check out rating system) so this will likely close schools. I would rate this a Category 3 Winter Storm due to the timing and the snow amounts plus the ice. Impacts are widespread. My forecast is 3-7 inches for MoCo. I think most areas will have less than 7 inches, but some areas could get 7 inches. Roads will be super messy because there will also be ice so MCPS will probably close. The models agree on snow to mix to rain. But they don't agree on the "jackpot" of the snow. This is looking good for snow lovers. At this point, it's almost a lock that we will get at least an inch. The Capital Weather Gang says half of MoCo is in Zone 1 and the other half in 2. Zone 1 means moderate snow and lots of ice. Zone 2 means some snow, ice, and rain. They rate it a Category 3 storm for Zone 1 and for Zone 2 and 3 they rate it Category 2.

First Prediction for Wednesday:

4.5 snowflakes
That means a 90% chance of closure and delay chances are almost 100%. This can easily change.

There will be more FAQs soon! Remember this is a FIRST prediction, so this will probably change as I get more info. Today night will be my second prediction and Tuesday Night will be my final prediction.
