About to Warm Up...
Boston hasn't seen 80 degrees since the first day of October 2010...months and months ago! That has a very good chance to change tomorrow...a warmfront will slide through late tonight and early tomorrow morning ushering in the warmest air in quite some time. As this front comes through, temps will actually rise later tonight and so will the mugginess...along with those two, scattered showers and maybe even a rumble will seen/heard tonight.
Tomorrow morning will start cloudy and foggy but the sun will come bursting through and temps will soar to the lower 80s. Dewpoints will also reach the lower 60s and the two will provide good fuel for thunderstorms to develop later in the day. Any storm that develops could have damaging wind, hail and very heavy rain.
The front and therefore the t-storm threat will clear the coast late in the evening. N/NE winds will pick behind the front this will bring in some cooler air at the surface creating a low-level inversion that will likely trap some moisture in it causing low clouds to form. The low clouds will be around early in the day on Wednesday then we should be in burn off mode for the afternoon. Highs will reach the lower 70s inland but stay in the 60s at the coast due to the persistent onshore wind...even if it is light.
For the end of the week and the weekend, high pressure will be strengthening off the East Coast...a good place if you like Summer weather. At the same time, a front will be migrating in from the west. There will be a very fine line between unsettled, stormy weather and dry, sunny weather...that line, right now looks like it will set up just to our west...but it could easily be over us. One thing is for sure there will be a flow of very muggy and pretty warm air...with a little luck we could end up with a pretty good start to the Summer season!
