Saturday March 31 2018
March started as a lion and is going out like a lamb. The good news is that the temperatures this weekend will be close to average for the end of the month. This times out well for our weekend and for holiday plans including Easter and Passover. But there is a system in the northern Rockies that will dive quickly across the nation and reach us Monday morning. The timing is perfect to arrive just before sunrise and tap into the cold air to produce snow for a few hours. I do not see this as a travel issue and it will be gone before noon. But still a something not welcome if you have switched momentum to Spring.
Today and Easter Sunday look to be dry and close to average temperatures.

Snow Monday Morning
This quick moving system will be with us for about 5 to 8 hours. It is expect to arrive between 2 and 5 AM and may start with all rain, or some snow mix in the normally colder northern areas (north of I-70 and the Baltimore Beltway. The best chance for snow will spread in and expect to near Baltimore between 5 AM and 10 AM, when it departs.
It this tine I do NOT think this will be a road issue, but rather stick on the grass, and in elevations over 500 Ft.

Temperature Outlook
Yes, it is possible to have snow AND 50ºF in the same day… especially in Spring if the sun comes out after morning snow. I do NOT think the snow in the morning will have cold enough air to stick on the roads. Just a grass thing.
