Back in the Heat...
Record breaking Central US heat has been bubbling into New England all day long. It has encountered some tough resistance from the cooler marine air over Eastern MA. A sneaky seabreeze has held it's own through most of the day but it is now losing the battle to the hot airmass that lies just to our west. As it succumbs to the heat we are seeing temp jumps of close to 10 degrees in one hour..this has shot most towns up close to 90 degrees this evening! Officially, so far, at Logan the temp has climbed to 89 degrees just one degree shy of that magical mark of 90 so if Logan didn't touch 90 between obs then there won't be another heatwave in Boston this time around. With that said, most towns have touched 90 or higher this afternoon, even the western neighborhoods of Boston did so the potential heatwave is still intact!
Tomorrow the heat peaks...winds will be westerly in the wake of a surface front that sweeps offshore later tonight. This front won't cool us off but it will bring the humidity way down and keep the breeze going so it will be a little more palatable tomorrow despite highs in the mid 90s and blazing sunshine. Sunday will be hot again but with a surface trough in the area and temps cooling aloft, there appears to be a good chance for thunderstorms which will keep highs closer to 90 degrees. In the wake of the through, temps will cool a bit and the 90 degree heat will retreat for several days. Currently, temps through the 4th will mostly be in the mid 80s and with some troughiness overhead, there will be a chance for thunderstorms on the 4th of July.
