Forecast discussion: We will have a cold front move through Southern New England in the next few hours. The cold front may produce a passing shower or sprinkle before midnight, before the front moves east of Providence. High pressure will give us a nice sunny day on Tuesday. But, once again, we will feel a strong west-northwest breeze during the day, before winds diminish through the afternoon. Increasing clouds will take over the skies for Tuesday night, as we wait for a significant storm located in the Central U.S. Wednesday morning will begin with the precipitation starting as some rain. As the day progresses, colder air from Canada will begin to move into the upper levels of the atmosphere. So, despite our air temperatures at the surface being above freezing, the precipitation will come down as snow. But, the American model as this time is bringing in warmer air than the other models. So, we may see more of a mixture of rain, snow, and sleet. By Wednesday night, the upper level winds will begin to get warmer air from the southwest. Because of this, despite our surface temperatures being colder than 32 degrees, the precipitation will come down as rain during Wednesday evening. As we enter Thursday, we will continue to see a mixture of precipitation until Thursday afternoon, when colder air once again reaches the upper levels of the atmosphere. So, for Thursday afternoon and evening, the precipitation will be light snow. The light snow will end early Friday morning. Because of this difficult scenario in the upper atmosphere, it is really difficult to try to put down total snowfall totals. If the rain/snow line changes by 50 miles, or if we see much warmer air reach the upper levels of the atmosphere, it will completely change this forecast. I’ll continue to watch the models tomorrow, and update you on my next forecast. Based on information from the National Weather Service, a Winter Weather Advisory may be needed. By Friday, we will see some sunshine. Another low pressure system will bring some heavy precipitation, in the form of rain, for Saturday. High pressure ridging will build into the area for Sunday morning through Monday.
