First Flakes?
Let's start with Today...a weak vort max will swing in from the Ohio Valley...this will produce some rain or snow showers in the Mountains and just some cloud cover East. The next piece of energy that drops into the base of the trof is the one we'll be watching for Friday Night. Most of the models now give it a surface reflection, so we can call it a Clipper. It will approach on Friday from the NW and the associated vort max will move in just South of us Friday Night and Early Saturday. There are a few things going here for some light snow: 1. The fact that it is coming through at night helps...the surface temps will be above 32, but most of the column above will be below freezing...so the flakes will be able to make it to the ground without melting. 2. The fact that the vort max passes South is good for precip...it has been my experience that when they pass North, we miss the rain or snow. The surface storm will actually explode off shore, but too far away for us to get into the heavy precip Saturday Morning. However....I do believe we have the chance for our first light snow of the season Friday Night. Don't expect much accumulation...if any...around the Metro Area...but there could be a nice coating in the Mountains.
