Forecast discussion: A strong high pressure system over southeast Virginia brought calmer winds Tuesday afternoon, but did not help with the temperatures in Boston. Although it was warmer than Monday, our high out of Logan Airport was only 22 degrees. As we head into tonight, we will see temperatures in the double digits. However, it will still be cold, as lows fall into the middle to upper teens.
On Thursday, we will see sunny skies with temperatures actually approaching 30 degrees. We will see some high level clouds moving over the state Thursday night, helping to keep some of the daytime heat over the state. Temperatures Thursday night will remain in the lower 20’s. By Friday, we will have limited sunshine, but our winds will turn to the warmer southwest direction. This will allow for warmer air from the south to begin filtering into Southern New England. However, we may see a scattered snow shower during the late morning, due to a weak disturbance passing through the area. Temperatures by Friday afternoon will actually go above freezing since Monday.
As we head into the weekend, temperatures will continue to rise, but we will be dealing with some rainfall. A low pressure system forming in the Southeast U.S. will move in a northeast direction. The front will pass through late Saturday night. We will see showers begin by late Saturday morning, with heavier rainfall in the afternoon and evening as the front inches closer. The rain will taper to showers by dawn Sunday morning, before all precipitation ends later in the morning. We will see another band of showers Monday morning, as a quick moving low pressure system brings more moisture over the region.
Temperatures will remain warm into Tuesday, until a new and stronger cold front brings the risk of a mix of rain and snow showers Tuesday evening. Colder air behind the front will bring our temperatures out of the middle to upper 40’s and back to seasonable conditions next Wednesday. A slow moving Alberta Clipper system may bring some rain showers by Wednesday afternoon.
