More of the Same...
A coldfront passed through the region today and will settle to the south in our coastal waters for the weekend. Before the front made it to Boston, the temp reached 79 degrees just before noon. Then the wind shifted into the NE behind the front and temps have been falling ever since...they are now in the 60s!
We will be on the cooler side of the front all weekend so expect below normal temperatures in the 70s especially near the coast. A shortwave trough will dig into the Mid-Atlantic spawning a weak surface low to ripple along the front. This will keep the NE flow going for most of the weekend locking in low-level moisture. Clouds and fog will be thick every night...thankfully this time of year the sun is very strong and during the early afternoons sunny breaks will chew through the overcast...especially away from the coast. With cool air aloft from the trough, any sun that we do see will aid in destabilizing the atmosphere, so pop-up showers and downpours will be possible especially in the afternoons. They will be scattered, and no washouts will happen. Not every town will see them...they will be most likely to occur inland.
The low will head out of here by Monday and brief surface and mid-level ridging will commence leading to some very nice Summer weather early next week with sunshine, warm and somewhat humid conditions Monday and Tuesday. However, much of next week, and the week after for that matter, will be dominated by a longwave trough in the East. This will keep a cap on the heat and very humid air will be present with a southerly fetch of moist air coming up from the SE US. Along with those two, the cool air aloft from the trough will keep a daily T-storm threat with us for several straight days leading into the first week of August.
Have a great weekend all...
