Today’s weather was disappointing for everyone in northeastern MA and along the coast through Boston onto the South Shore. The western flank of the slowing system offshore resulted in bursts of mist and brisk winds. I had expected the sunshine from the west to break onto the coastal plain but the blocking spoiled that scenario. In the sun-heated air, the anticipated afternoon heavier showers and storms rumbled into central MA and RI. Those will weaken quickly this evening as the original ribbon of rain which soaked the region yesterday begins to rotate and pivot southward where it has been stalled over ME all day today. Thus, in April, we had some June-like weather and now we’ll have just the reverse over the next few days. The weather block that never materialized this past winter is in full swing now. Consequently, anomalously cool weather accompanied by occasional rain and mist will make it damp, dank and dismal into Wednesday. The surface low pressure system over the Gulf of ME will track southward and eventually shift far enough out of the picture to reduce the wind and rain. In the meantime, with a tightening pressure gradient, the north-northeasterly wind will increase up to 15-35 mph with a few gusts of 40-45 mph along the coast late tonight through tomorrow night. This strong onshore wind will enhance the extra high tides due to astronomical conditions. Consequently, expect some minor coastal flooding later this evening followed by a greater threat of minor to moderate flooding tomorrow night. High tides are scheduled for about 11pm tonight and just before midnight tomorrow night. Shore road closures are likely along with some wave battery and beach erosion.
Looking ahead, this blocking will weaken later in the week so sunshine will become more noticeable with only a few showers possible Thursday. A disturbance digging southeastward from Canada will trigger a swath of showers and storms later Friday afternoon and the rain could linger into early Saturday. After that, building high pressure will lead to a warmup next weekend and perhaps 80-85 by a week from tomorrow with the 85-90 the day after. That’s next week.
