With a high pressure area drifting toward the Middle Atlantic coast, it's a fine day from the Great Lakes through the Northeast. Another high pressure area from southern Canada will take over from north to south on Sunday and dominate the region's weather early next week. Along the front separating the two high pressure areas, some showers and thunderstorms will develop, and they can affect the central and northern Great Lakes region tomorrow, then the area from coastal New England through Pennsylvania to the Ohio Valley on Sunday.

A short summary of the current weather scene:
In the wake of a serenely cool and settled September sunrise, today will be simply super with scintillating sunshine, subtle stirrings, and sensible seasonality in a sublime and splendid setting. Temperatures will top off in the 70s, then sink back to the 50s at night. It's something to savor. All will be well with our world as we head through the course of an easy evening, followed by a late night when fingers of fog spread past farms, fields and factories, favoring the valleyways and cloaking the morning in a membrane of mist while encapsulating the blades of grass in a glassy envelope of drippy damp droplets of dew.
Yes, the Northeast is settling down into a period of tranquility and bliss. There'll be two and perhaps three days of dry weather with moderately warm afternoons and comfortable nights. It won't just be the comfortable serenity and sunny geniality of the days, but the untroubled soothing coolness of the nights. This run of pleasantness will encourage and hearten while reducing the tension and unpleasantness that unsettled weather or extremes of one kind or another can bring. Yes, it will be a time of pleasurable delectability, delightfulness and amenity, winsomeness and charm, enchantment and harmony, frictionless joy, soothing tastefulness, pleasurable tranquility, and exhilaration and happiness, not to mention zesty oblectation plus grace and gratification.
Now, drier air has arrived, and most of the Northeast will have abundant sunshine today and tomorrow.
A front that will usher in slightly less humid air for the Northeast tomorrow will trigger locally strong thunderstorms today.
Thunderstorms will continue to erupt near the northern edge of the heatwave, enhanced by a series of disturbances rippling along in the upper air flow. This is the NWS Storm Prediction Center's severe thunderstorm outlook for today
... the main upper air steering current moves eastward across the northern Plains, then dives southeastward toward the Middle Atlantic states. The core of this current defines the rim of the hottest weather and serves as a conduit for clusters of thunderstorms.
3. Hot air will be moving east from the Plains, reaching the major East Coast cities Friday and Saturday. This map shows the upper-air flow that will make this happen.
This map shows lightning strikes from 8 a.m. EDT yesterday until 7:20 a.m. EDT today. A concentration of thunderstorms can be seen in the Midwest ahead of the cold front.
