Today's Weather: A Mild Start To March, And Meteorological Spring

Meteorological spring began yesterday on a cold note. This was a departure from the meteorological winter, which ended up as the second warmest in Boston ever recorded.

Our first week of March is going to be a mild one. Temperatures will get into the 40s and even lower 50s today. Although it's chilly at sunrise, readings will warm up quite quickly.

The cloudiness we will experience today is a result of warmer air. As warm air moves into a region with cold air, it is lifted up and over it, and often produces clouds.

There are a couple of weak weather systems that will affect the region Tuesday and Wednesday.

Shower activity will be limited. There could be a couple of showers overnight, and there may be a few more again tomorrow during the overnight.

Wednesday morning could see a shower before skies return to becoming partly sunny. If there is going to be a commute affected by wet roads, I think Wednesday morning is the most likely.

Thursday is a beautiful day, with readings near 50 and plenty of sunshine, along with light winds.

Later this week, we'll be watching a storm system developing off the coastline. If the storm comes close enough to the coast and there's cold air, we could see some snow. But there's also the possibility that it ends up as rain — or absolutely nothing. It's definitely something to keep an eye on, but there have been many false alarms all winter, so it's just a watch for now.
