Most of the day stays dry, but the moisture-rich air will turn out a shower or two , so pack the umbrella just in case.

Partly to mostly cloudy skies will remain Wednesday night with a low shower chance as lows slip to the mid and upper 60s.

Wednesday’s weather will be influenced by a warm front gradually progressing through New England from the southwest, bringing along warmer air, more humidity, and the chance for a shower or two in Greater Boston and most of Southern New England.

A steep southerly flow with the front will lead to plenty of clouds throughout the day, but there should be a few cracks to let the sunshine in at times. The air will have plenty of moisture so the chance of a spot shower or two will linger throughout Wednesday, morning and evening. Should more sunshine crack through the clouds then there’s the chance for an isolated downpour with the additional heating. Any precipitation should be brief.

For the commute in, it’ll be in the the mid- and upper 60s with highs building to the mid- and upper 70s. There will likely be a few spots that reach 80 around or west of I-95, wherever the sun breaks through the clouds.

You’ll notice the heavier air when you head out in the morning, with dew points around sunrise already in the low 60s. By the time you wrap up work for the day, the air will feel thick and heavy with dew points in the upper 60s.

But come Thursday, it’ll feel like Southern Florida, with dew points reaching the low 70s.

Dew points in the 70s are a precursor to a chance for a brewing storm, and New England, including Boston, will see a thunderstorm chance come Thursday afternoon and evening.

Under a blend of sun and clouds, highs will be near 90 degrees in Boston with higher readings west of the city. Mixing in very humid and moist air, the atmosphere will be primed for a classic line of thunderstorms to develop ahead of a cold front pushing into the region from the west. Some will turn severe with damaging wind gusts and heavy downpours. Boston should see any action after the commute home but that may change as we get a bit closer to Thursday afternoon.

So far so good. The trend is that high pressure will linger near New England on Saturday with it holding on long enough through Sunday. There may be a few showers well west of Boston but there’s growing optimism for a completely dry weekend.

That would snap 14 straight weekends where a trace or more rain has fallen in Boston.
