Greater Boston, North Shore and Metro West: It has been a long time since we have experienced a period of dry weather. After several weeks of rain and snow we are settling into a drier pattern with the possibility of no precipitation for the next 5 to 6 days. This is mostly courtesy of high pressure that has nestled into the region and is in no hurry to leave. A blocking pattern over the north Atlantic will help slow systems to a crawl over the next week or so.
Temperatures near the mid point of April have been running about 2 degrees below average in Boston. This is mostly due to the very chilly week we had the first week of the month when there were days the mercury ran some 20 degrees or so below average. Through the first 14 days of the month 9 have been below normal. The highest reading so far was on the 1st, before the mercury crashed back to winter, when it hit 69 in Boston. The lowest was 22 degrees on the morning of the 5th during our revisit with Old Man Winter. Average highs and lows for mid April are 55/40 and over the next couple of days we will struggle to reach those numbers along the coast because of a persistent ocean breeze.
Looking ahead we have the long Patriots Day weekend, the Boston Marathon on Patriots Day, the Red Sox are on a home stand and through all of next week many of the school districts are on spring break. With all of that in mind the change in the weather pattern is a timely one for those of us that are eager to get back outside and enjoy what should be exceptionally nice weather well into next week. The only issue will be those pesky ocean sea breezes that will knock temperatures down during some afternoons. The farther inland you are the better your temperature recovery will be so that the afternoons will not force you to run for the heavier sweatshirt or jacket.
High pressure will dominate our weather through at least Tuesday of next week. Once this high moves to our south it will create a more southwest airflow and with that come the milder temperatures for Sunday and Monday. Even coastal locations will share in the milder air. Then a cold front crosses the area sometime late Monday or Monday night. Once that happens cooler air once again overspreads the region for the middle portion of next week.
Here is a snapshot of the weather outlook for the next 5 days:
Mostly sunny days and fair skies at night into Patriots Day. Highs generally in the 50s Friday and Saturday, then into the 60s Sunday, although a cooling sea breeze may still persist along the shore. Patriots Day now looks to be the mildest day of the period with temperatures crossing into the low 70s for many. The cool down Tuesday and Wednesday drop highs back into the 50s. Overnight lows mainly in the mid 30s to mid 40s with the mildest nights on Sunday and Monday.
There will be a period of clouds late Patriots Day and Monday night with the passing of the cold front. Then on Tuesday a sunny start followed by afternoon clouds.
