How about that weekend? Yesterday was especially splendid and would you concur that it was close to a perfect 10 June day? The highs around 80, a pleasant breeze, the low humidity and a mix of sunshine and clouds were a great combination. It was nice while it lasted and it isn’t lasting much longer as we see the high cloudiness already increasing this morning. The timing is working on our behalf as most of the rain had fallen by daybreak Saturday and the next round arrives later today. Yes, indeed, another drenching with spotty lightning and thunder is on the menu but it will not match the magnitude of the Friday and Friday night deluge of 2.5 to 5″. Nevertheless, a projected 1 to 2.5 inches will be adequate to produce more flooding in poor drainage locations and place the small streams and some of the small rivers into flood stage. Consequently, the National Weather Service has posted another Flood Watch for most of the region excluding Cape Cod for this evening through tomorrow evening. Watch for more ponding on some of the roadways tonight and early tomorrow morning as the greatest amount of rain falls west of the I-95 corridor with the least probably near or under an inch over Cape Cod. Once again, thankfully, there will NOT be any coastal flooding with this system either. There will be less wind with this feature compared to the Friday night storm. An approaching warm frontal boundary will advance northward into extreme southern New England as a wave of low pressure runs along it tonight and exits on the Plymouth County coastline tomorrow morning. Showery rains will break out northeastward as the boundary closes in on the area from the southwest. The main thrust of rain will surge into CT and western and central MA later this afternoon. It should become wet in those places by mid-late afternoon as the showers slowly shift eastward into the Boston area by early this evening and over Cape Cod by mid-evening. There could be some areas of dense fog tonight as well. With the departure of this wave first thing tomorrow morning, it will be murky and damp with only some mist and a few sprinkles lingering during the commute. As another impulse arrives in the afternoon, more showers and some scattered boomers will break out. The good news is that NO severe weather is anticipated because little or no sunshine means less destabilization of the atmosphere. It will warm up to the lower 70s inland with upper 60s at the coast today with lows of 57-61 tonight then back up to the middle to upper 60s tomorrow.
Looking ahead, as the upper level low pressure and surface features linger Wednesday morning, it will still be damp with some scattered showers and some mist. As these systems start their departure in the afternoon, drier air means some breaks of sunshine should occur sending temperatures up to the lower 70s by the end of the afternoon. After that, a ridge of high pressure will build in to completely clear the sky Wednesday night. It will cool off to the lower to middle 50s with nice dry air. The next weather maker will already be sending some feathery clouds into the Northeast later Thursday morning and it will probably become cloudy in the afternoon. The next wave disturbance transiting along a frontal boundary in the Midwest will be steered south of New England Thursday night into early Friday. At this time, there is some uncertainty regarding the extent of its northern fringe of rainfall. Presently, I will predict that some showers may graze southern CT, southern RI and the lower Cape for a few hours early Friday before the developing storm is kicked southeastward by a cold front moving out of southern Canada into northern New England. So the sunshine will take over by midday Friday followed by the risk of a brief shower with the front Friday night. If this scenario verifies, we’ll be set up with another wonderful weekend with high pressure taking control and providing dry air with delightful temperatures of 75-80. How sweet is that?
Looking way ahead, there are still NO signs of any real hot weather through at least the first day of astronomical summer. That works for me!
Joe Joyce posts his blog by early this evening and I shall return early tomorrow morning.
Make it a great day!
