The air change is noticeable across New England on Tuesday, with a drop in temperature and dew point – the measure of the amount of moisture in the air – but with the energy that drove the front Monday cold across the region still drifting east over New England, renewed and scattered showers and thunderstorms are expected in the north of the country.

While cold air aloft can bring small hail to the heart of these northern storms, central and southern New England will remain mostly dry with only a few isolated splashes and light showers falling in spots during in the afternoon due to the construction of puffy cumulus clouds.

The drier air for most of us will mean drying fast enough to provide moderate bushfire danger across the region in the afternoon and the breeze blowing at 40 mph at times from the west will make fall just about all types of pollen.

Dry air tends to cool quickly with loss of sunshine, so overnight on Tuesday evening low temperatures will drop to 30 degrees in the north and 40 degrees in the south before a quick rebound to 70 degrees in sunshine on Wednesday afternoon.

The next disturbance to cross the New England skies comes on Thursday, with showers moving west to east Wednesday night and through the first half of Thursday before the wind shifts from a moist southerly ocean flow -east or east to a westerly wind by afternoon to begin the drying process again.

Thursday’s showers mark the start of the return of warm weather which will be felt on Friday, then really turn around Saturday and Sunday with high temperatures in the 80s, increasing humidity and a chance of afternoon thunder both afternoons. weekend noon, but especially as a cold front approaches later on Sunday or Monday.
