Cooler in the Northeast Thursday and Friday; Hotter next week
Updated Jul 20, 2021 9:26 PM EDT
The recent flow in the upper atmosphere has allowed extensive amounts of smoke to spread eastward from the multiple wildfires now ravaging the West. Fortunately for residents of the East, the smoke is high enough that there was very little effect at ground level except for the haziness of the sky and dimming of the sun. There have been some super spectacular sunrise and sunset pictures and that opportunity will continue. In the visible satellite picture below, you can trace the smoke across central Plains and all the way out past southern New England. Notice a grayish color off southern New England versus blue sky (where there is no cloudiness) in areas from Virginia south past Florida.
The satellite radar composite shows an area of showers and thunderstorms just north of the eastern Great Lakes. Those showers more to the location of a cold front that will pass through the Northeast states between now and Thursday morning. Somewhat cooler and drier air will follow the front, but then some moisture associated with the cloudiness we see in Montana and North Dakota could affect the region as we go through the weekend.
The GFS forecast map for Tuesday evening shows some of the showers extending southward as far as Pennsylvania.
Wednesday could be a changeable sort of day from Pennsylvania to New England, sometimes dark and threatening with a shower or thunderstorm and other times brighter with the promise of clearing.
On Thursday, there could be some leftover cloudiness downwind from the eastern Great Lakes and in northern New England.
Friday looks like a nice day from the Ohio Valley through Pennsylvania and New Jersey but there could be clouds spotty showers farther northeast.
Saturday looks favorable for outdoor activities in most of the Northeast and Middle Atlantic states. However, it appears that showers and thunderstorms will cross the Great Lakes and some of those could reach the Northeast on Sunday and Sunday night.
The cold front approaching this weekend may be the last one for a while as reflected in the higher temperatures for next week in the sample forecast below:
