Fall is here, but Summer doesn't want to let go

Maria's current track keeps it away from land

TONIGHT: Clear to partly cloudy and comfortable. Low: 56

SATURDAY: Mostly sunny and very warm with some patchy fog around in the morning. High: 88 

SATURDAY NIGHT: Clear and mild. Low: 62

While the sun has set on another season of Summer, it sure didn't feel that way on Friday. At 4:02 PM the season officially changed to Autumn (or Fall). However, with daytime highs once again extending well into the 80s and plenty of sunshine overhead it felt like a midsummer day. Post-Tropical Cyclone Jose continues to spin off the southeastern coast of New England, but as was the case on Friday it's basically a non-issue for us moving forward. It's a different story if you're heading to the shore. Keep in mind that Jose will continue to produce rough seas and dangerous rip currents through the weekend, so please be careful.

The strong ridge of high pressure centered to our west is responsible for the sunny, summery day on Friday. This high will continue to be the dominating weather feature through early next week. This means the area will see clear to at worst partly cloudy skies at night and mostly sunny skies during the day through Monday. While temperatures may dip into the 50s tonight, after that look for them to stay in the 60s. Over this stretch, daytime highs will be in the upper 80s to near 90 degrees. That may not be enough to break any record highs, but it will certainly be enough to challenge them. 

Tuesday and Wednesday will remain dry and very warm, but we'll start to see the cracks in the foundation of this pattern. Daytime highs will slowly retreat from the mid-80s on Tuesday to the low 80s on Wednesday. Meanwhile, we'll start seeing a little more cloud cover. Some of those clouds will be the outer bands associated with Maria. What those clouds mean is that the dominating ridge of high pressure isn't as dominating as it once was. 

By Thursday, the area of high-pressure slides off the coast and a cold front will move in from the west bringing the possibility of showers to the area. This front will also bring cooler temperatures to the area, but they're not necessarily cool for late-September. In fact, the upper 70s we'll see on Thursday are still roughly 5 to 10 degrees above normal.

Meanwhile, we continue to monitor Hurricane Maria. Maria's current track has the eye of the storm exiting the Turks and Caicos area and passing east of the Bahamas through Sunday. The storm is moving northwest and should eventually make more of a northerly turn over the weekend. Maria is not expected to lose any significant strength through the weekend. As it moves into the colder water churned up by Jose we will see Maria start to weaken early next week. By that time Maria will be passing safely between the East Coast of the United States and Bermuda. Once again, the East Coast beaches will have to deal with rough surf and dangerous rip currents. This is not good news for those folks trying to get a few beach days in before cool Fall weather arrives for good.
