Metro Boston, North Shore and Metro West: If you thought it was excessively cold this first week of March you are correct. The temperature departure from normal in Boston was 10 degrees below the average and that is a significant number over a period of a week. Although we had temperatures climb into the 30s on Friday those readings still remained 5 to near 10 degrees below the average for early March, yet it was a pleasant day overall. It tells you something about how use we have become to the cold. We will do better than that on Saturday as temperatures break well into the 40s. In any event, with light winds and a good amount of sunshine it will feel like Spring and at this point we take anything we can get.

A brief warm up is in store for Saturday ahead of the next cold front passage at night.

A weak cold front moves through Saturday night and this will taper back temperatures on Sunday as cooler air overspreads the area on brisk northwest winds. A disturbance in the upper levels moves through Sunday night and early Monday and could set off a few flurries or light snow showers. By Monday afternoon temperatures recover to near seasonal levels.

Tuesday, milder air rides in on southwesterly winds ahead of an approaching cold front. Temperatures are expected well into the 40s with a fair amount of sun. The cold front passes through at night dragging cooler air across the area for Wednesday. There is a slight chance of a flurry associated with the frontal passage.

Developing low pressure emerges out of the lower Ohio Valley and rides along a frontal boundary to our south. Although this has the potential to be a significant storm for later Wednesday and Thursday as of now the evolution of this storm is still in question. Precipitation timing, amounts and types remain in question. There is an equal chance that the storm does not come together and tracks too far south to do much of anything here but give us a glancing blow or completely miss. More to come on this later in the weekend.

Colder air returns on the backside of the departing storm for Friday.

Don't forget to turn the clocks ahead one hour tonight as Daylight Savings Time returns Sunday.
