Friday December 15 2017 2 PM (reposted after site crashing)

Light snow mixed with some sleet and freezing temperatures. That what we finally settled on and it has shown itself. I apologize for my website being down for a time today, but below is information in animations and sliders that I can not share all together on social media. I hope you take a look and see how this weather event will play out for this afternoon and evening. The roads will get more slick after 3 and 4 PM, but snow will ease up in metro areas as it gets dark.

The Winter Weather Advisory has been extended on the Eastern Shore of Maryland for Talbot County until 9 PM.

Talbot County in Maryland has been added to the advisory until 9 PM. the western shore of the Bay will be until 7 PM


Radar Animation

Bands of light snow have spreads across out region. It was mixing with sleet along I-95 and around the Bay.  Notice the broken feature near Annapolis and Washington. This is where the jet streak entrance is helping to form the snow we have. As I wrote this morning… we will see this develop on top of us.


Note: All SnowStix order through midnight tomorrow will be shipped before Christmas.

The NAM 3 KM model has been the best performing with this event, but still not perfect. That is what made this difficult to pin down and still the plot the snow totals.

Notice the darker blue. This is the enhance snow for a few hours that will make for the worst roads between 3 and 5 PM. Then the focus will shift across the Bay to the Eastern Shore.

This is a high resolution and rapid update, yet keeps missing out on the back edge of the snow. This is void of the snow beyond Westminster to Frederick and north to York. But I am shoring this to highlight the enhanced snow through 4 and 5 PM… Shifting to the Eastern Shore.


Potential Snowfall

Please note that some of the regions are overlapping. This is due to the wide range expected as the bands develop. It is tough to track before they form.

A: Back edge of flurries or light snow that may drop of coating.

B: Between a coating to 2 inches. This depends on where the snow bands set up.

C: Between 1 to 3 inches. This depends on where the snow bands set up.

D: May have rain or sleet during the day and change to snow after 3 PM. Snow this evening could drop a coating to 1 inch and lead to slick travel.



Yes, temperatures wil stay below freezing, so additional salting will be needed.
