Forecast discussion: High pressure gave Boston some sunshine during Monday morning, before clouds increased in the sky during the afternoon. The high will slowly move eastward, and provide us with partly cloudy skies into Tuesday morning. During Tuesday afternoon, our skies will fill with clouds, as we await another storm system.
The low is currently over southeast Oklahoma, bringing thunderstorms to Louisiana and almost a foot of snow to Kansas and Oklahoma. The low will slowly move east, and a second low will form over western North Carolina by tomorrow night. The precipitation will arrive just after midnight early Wednesday morning. South of the Mass Pike should see a combination of rain and snow, before changing to all rain by mid-morning. In fact, the precipitation may be heavy at times just before dawn, and through the morning commute. The area seeing snow and sleet could see a dusting to about 1 inch before we change to all rain by mid to late morning. By early Thursday morning, the precipitation may change back to some snow showers across the state.
The weather will remain unsettled, as the primary low slowly works its way into northern New England. The low may help produce some scattered snow and rain showers through Thursday, before seeing scattered snow showers end by Friday morning. However, little accumulation is expected during this time period.
As we enter the weekend, it appears we will break our streak of seeing a storm system during this time at three weeks. However, the long range computer models are forecasting some upper level dynamics around the Southeast U.S., which will help develop an ocean storm. At this time, it appears the low will form far out in the Atlantic, and we will not see any effects from it. So, I will keep partly to mostly sunny skies for the upcoming weekend, with highs in the middle 30’s to as high as the lower 40’s.
