Forecast discussion: Boston had a cold front come through the region earlier in the day on Friday. Instead of seeing snow or a wintry mix, we had very mild temperatures on this late February day. So, the precipitation came down as rain. Also, there was enough upper level dynamics with this system to actually create thunderstorms with lightning. However, the front has now moved offshore, and skies will begin to clear early Saturday morning.

High temperature forecast for February 22, 2014

High temperatures will remain above normal over the weekend thanks in part to southwest winds. our high temperatures will remain in the middle to upper 40’s. Bright sunshine is expected for Saturday, with some increasing clouds early Sunday morning. A frontal boundary will come down from Canada, and help to bring a weak disturbance through Southern New England Sunday afternoon. We may see some isolated rain showers at first, but then any precipitation will change to snow showers. This activity will not last very long, as any snow showers will end by the middle of Monday morning.

By Monday, you will notice that the mild air will be gone. A strong push of Arctic air will once again take over the east coast. Although it will not be as strong as the polar vortex earlier in the winter, temperatures will fall quickly into the lower 20’s by Friday, with low temperatures in the single digits Friday night. Also, the computer models do suggest a coastal low will form early Tuesday off the coast of South Carolina. This low may help trigger some light to moderate snow on Wednesday. There is a weaker low over New York that may help the first few snow showers on Wednesday morning. At this time, I am not sure if we will be seeing any significant snowfall amounts, as there is a chance the low will move further out to sea.
