Boston weather, metro north and west: Weekend Forecast

Boston weather, metro north and west: Weekend Forecast, After some pleasant spring like weather earlier this week we sure did end the work week ugly. With temperatures generally in the 30s throughout Friday we had a cold rain with even some sleet and a few flakes mixed in for good measure in some locations. That will be behind us as the weekend unfolds and we have a return to seasonably cool weather and then a milder trend early to mid week of next week.

The storm responsible for yesterdays unsettled weather continues to pull away from the area. Saturday starts off cloudy with gradual improvement later in the morning. An early sprinkle or shower is possible, otherwise a dry day ahead. Sunshine returns for the afternoon. Highs generally in the mid to upper 50s inland, however winds off the ocean will keep it chilly on the coast with highs only around 50 degrees. Northeast winds 10 to 15 mph on the coast, with a more north to northwest wind inland.

Skies become mostly cloudy Saturday night and a chance of a few sprinkles, light shower or even a flurry courtesy of an upper level disturbance. Lows cooling into the mid to upper 30s. Light west winds.

On Sunday, the upper level disturbance lifts out and we should see far more sun than clouds. Although temperatures may be a few degrees lower inland they will be a few degrees higher on the coast as a land breeze from the northwest will be in place. Expect highs in the low to mid 50s. A ridge of high pressure will also be moving into the area and by evening winds should diminish as we get set up for a chilly night under a mostly clear sky. Lows in the mid 30s with a few low 30s in the outlying areas and usual colder valleys.

High pressure takes firm control of the weather on Patriots Day and we are in for a fine spring day with plenty of strong April sunshine. After a cool start to the day the mercury will quickly jump through the 30s and 40s, topping out in the upper 50s inland. However, a sea breeze keeps temperatures in the low 50s on the shore. That means the marathoners will be heading into the wind as they approach Boston. Winds will come around to the east and then southeast at 5 to 10 mph.

A partly cloudy sky and not so cool temperatures are in the mix Monday night. Lows in the upper 30s to 40 degrees.

By Tuesday the ridge of high pressure will be offshore setting up a milder flow. Meanwhile, a strong low pressure system will move well west and north of New England Tuesday and Wednesday through Ontario and Quebec. The attendant cold front to this low will pass through northeast Massachusetts and the metro Boston area late Tuesday night or early on Wednesday. With the approaching front we can expect an increase in clouds Tuesday and Tuesday night, with a chance of showers Tuesday, Tuesday night and early Wednesday. Temperatures in the low to mid 60s both days, with the lows in the mid to upper 40s Tuesday night.

Enjoy your weekend.
