All good things must come to an end and that rang true today. After several consecutive ”sunsational” weekends, our luck ran out with showery rains of varying intensity on this second day of June. The wet weather spoiled many various outside events like weddings, commencements, graduation parties, golf tournaments, charity walks, etc. The good news is that a break is projected for tomorrow so the whole weekend will not be a washout for southern New England. As a dry slot pivots into the area late tonight following some exiting downpours and isolated lightning in places this evening, drier air will flow in from the southwest as a weak wave of low pressure tracks across Boston to the western Gulf of ME. The ribbon of rain offshore will stall and soak much of ME and northern NH through most of tomorrow so some flooding in that portion of the region is likely while the FLOOD WATCH has been cancelled for southern NH and northeastern MA. After tonight’s lows of the upper 50s, it should warm up to 74-78 tomorrow with the help of some sunshine. As the atmosphere becomes unstable from approaching colder air aloft, building clouds will trigger scattered mid-late afternoon showers and boomers. There could be some small hail in places.
The area of stalled rain way up north will be steered south so the wet weather will collapse back into southern New England in a weakened mode late tomorrow night or early Monday morning as the wind becomes northeasterly. The pressure gradient will tighten during Monday so northeasterly gusts to 20-35 mph are possible along the coast with 15-25 mph inland. This increasing onshore wind will kick up the seas and enhance the already exceptionally high tides due to astronomical conditions. Consequently, I expect that minor to pockets of moderate coastal flooding could occur Monday night. The tide is high close to midnight. We’ll be closely monitoring this situation. Expect occasional mostly light rain and drizzle Monday with highs only in the middle to upper 50s. Tuesday will remain dank and raw with occasional to periodic lighter rain and mist and highs in the upper 50s to near 60. The clouds will hang tough on Wednesday but some bursts of brightening and a few glimpses of sunshine cannot be ruled out enabling a slight warmup to the middle 60s. Slow improvement is scheduled for the second half of the week but any spells of sunshine will result in scattered afternoon showers. Hopefully, it will be sunnier and warmer next weekend as the present Greenland-Quebec atmospheric blocking that was missing all winter long starts to break down a bit.
Joe Joyce will deliver his AccuWeather Forecast in the morning and I shall return later in the day.
Enjoy the rest of the weekend.
