Thursday Overview: Cooler and drier air arrives

After a cold front passed through with some showers and thunderstorms on Wednesday evening, another cooler and drier airmass has settled into the area. Temperatures are in the 50s and lower  60s over the region early this morning. High pressure will provide beautiful weather, with mostly sunny skies today. Temperatures will only reach the lower or middle 70s this afternoon over the region. Which is big refreshing, difference from yesterday 90 degree heat. These temperatures are also slightly below normal for mid-September.

Mostly clear skies and calm winds, will lead to more radiational cooling tonight. Temperatures may get down to 50s and some 40s over much of the region. Closer to New York City, low temperatures may be closer to 60. You may want to wear a light jacket or sweater headed to work or school tomorrow morning. Friday and Friday night will be similar to today and tonight, with high pressure remaining in control. Some other highlights over next several days.

Surge of cooler air likely to begin the week

A strong cold front, with an impressive thermal gradient, will push from the Ohio Valley through the Northeast late on Sunday evening. This cold front is associated with a larger mid and upper level system, which features an organized and deep trough emanating from Canada. The cooler air associated with this trough will be most prevalent in the Plains and Mississippi River Valley, but will also be noticeable in our area for a day or two behind the front.

This will be most recognizable on Monday and Tuesday, as atmospheric temperatures significantly cooler than the past several weeks settle overhead. Daytime highs will be cooler — and dew points will be much lower. Overnight lows may fall into the 50’s in the interior and 60’s even in the city and near the coast.

Weekend Overview: Warmth, scattered storm chances return

Worry not! When we say “warmth” we don’t mean the oppressive heat from last weekend. Instead, what will return this weekend are temperatures more typical of late summer. Highs in the upper 80’s will be commonplace throughout the area this weekend, especially away from the area shores. Showers and thunderstorms are possible on each day, most likely during the afternoon and evening, but aren’t expected to be severe. They’ll remain isolated to scattered throughout the area.

Winds will turn southeasterly by Saturday afternoon and evening, meaning the influence of the area waters will be felt a bit more near the beaches. A bit more of a breeze and cooler temperatures are likely near the coast on both Saturday and Sunday. This southeast flow comes ahead of a cold front, which is expected to bring a period of steady rain on Sunday Night. Here are your weekend weather highlights:

A few showers tonight, cooler weather will follow

High clouds are streaming into the area this afternoon ahead of a low pressure system, which is located well to the west-northwest of our area. The associated cold front, however, will sweep through the Northeast States later tonight into early Sunday. After a generally pleasant Saturday, a period of unsettled weather is likely from Saturday Night into early Sunday morning, with moisture pooling along the cold front and aiding in the development of showers throughout the area.

This front will eventually swing east of the area by later on Sunday morning. Behind it, another shot of cooler air will make its way through the Northeast states. Mid level temperatures will drop by several degrees, and northwest winds will begin in earnest. But this won’t occur fully until later on Sunday evening — and so despite the cooling occurring in the mid levels of the atmosphere, high temperatures will end up being quite pleasant. After the showers on Sunday morning, in fact, temperatures will reach into the mid 60’s with abundant sunshine.
