Forecast discussion: Boston was pretty cold early Friday morning, as the mercury fell to 16 degrees at Logan Airport. However, we did not break a record. For the record, we would have had to tie or break the all-time low of 12 degrees, set back in 1896. The good news is we will see rather balmy temperatures for Saturday. However, we will be returning to winter by Sunday.

High temperature forecast for March 15, 2014

A high pressure system down off the coast of Florida provided us with bright sunshine on Friday. However, we will be seeing a low pressure system moving over eastern Canada will bring us a warm front for Saturday. Along with southwest winds and warmer air to the upper levels of the atmosphere, we will see high temperatures reach the lower 50’s. However, we will see some rain showers during the early morning, before ending around the mid-afternoon. Skies will begin to clear until sunset. As we move into Saturday night, the cold front will pass through, helping to lower our temperatures to the lower 30’s for daytime highs for Sunday.

The colder air will remain into Sunday night, and a developing area of low pressure over eastern Texas will create a massive storm for the Mid-Atlantic. A second low will form over North Carolina, as the main storm settles over Georgia. The second low will bring precipitation closer to Southern New England for Monday. Right now, the computer models are beginning to come together on this scenario. If the models hold true, there is the chance that Boston would see snow showers by the early afternoon. Any snow showers will then end by the evening, and well before midnight. High pressure from Canada will then settle over the area for Tuesday.

We would get another round of precipitation by Wednesday, as a low pressure system moves through the Northeast U.S. We would see rain showers at first, by Thursday afternoon, before changing to snow showers by the evening. Any leftover snow showers would end by early Thursday morning. As we head into the end of the week, the cold air will move back north, as high pressure changes the wind direction back to the south. This will help raise temperatures into the lower to middle 40’s, with temperatures slightly below freezing Friday night.
