Comfortably warm sunshine to wrap up the weekend

Solar eclipse will peak around 2:43 p.m. Monday

TODAY: Sunny, pleasant, and warm with low humidity. High: 84

TONIGHT: Clear and comfortable; some late night patchy fog. Low: 62

MONDAY: Patchy morning fog; otherwise sunny to partly cloudy and warm. A spotty p.m. shower or t-storm.  High: 87  Low: 69

 

Despite a few gusty thunderstorms across parts of the area Saturday evening, the first half of the weekend featured warm and increasingly comfortable sunshine on Saturday as humidity levels gradually lowered throughout the day. That sunshine returns for an encore on Sunday, as the weather should fully cooperate with any outdoor plans for the rest of the weekend.

As high pressure crests overhead, it will ensure a sunsational Sunday with abundant sunshine, seasonably warm highs in the mid 80s, and still refreshingly low humidity levels. So even though a few of us saw those Saturday night storms, both weekend days will feature dry and pleasant summer weather. Mother Nature is thankfully abiding by the unwritten rule that if it has to rain on the weekend, make sure it rains at night.

Monday will bring us the highly anticipated “Great American Eclipse,” a relatively rare total solar eclipse of the sun. Granted, we won’t see totality here in Pennsylvania and New Jersey, as you have to head well to our south to the Carolinas, Tennessee, and Kentucky to see 100 percent of the sun entirely blocked by the moon for a few minutes Monday afternoon.

However, we’ll still be able to see a partial eclipse, around 75% coverage, and most importantly, we should have pretty good viewing conditions with at least partly sunny skies currently expected on Monday afternoon. There may be an isolated thunderstorm or two approaching from the west later in the day, but hopefully not until after the eclipse has ended.

The eclipse will begin around 1:20 p.m. and end around 4 p.m., with the peak occurring around 2:43 p.m. and lasting just a few minutes. Remember, never look directly at the sun without special glasses as damage to your eyes can result. You can also safely view the eclipse by making a special “pinhole” device to portray the effects on a piece of paper. If you miss this eclipse, the next one doesn’t occur until 2024.

Beyond the celestial show, much of the week looks fairly quiet, one of the nicer and drier forecasts we’ve had amidst a very wet summer. The only other chance of rain is in the form of a few scattered showers and thunderstorms Tuesday night or early Wednesday morning. Otherwise, it’s a welcome break from the repeated rounds of wet and stormy weather that have plagued us over the last six weeks.

Temperature-wise, the heat and humidity will make a brief return to the area on Tuesday, and help fuel any Tuesday night thunderstorms. 90-degree temperatures are possible Tuesday, which will be the hottest day of a forecast that will trend cooler and more comfortable later in the week as a longer lasting shot of Canadian air settles in for an extended stay, likely right through next weekend.

The tropical Atlantic has gone from rather active to less threatening over the last day or so. Tropical Storm Harvey weakened in his trek across the Caribbean Sea, degenerating into an open tropical wave Saturday night. While there are a few more tropical waves in the open waters of the Atlantic, chances for development have been lowered across the board, so there are no imminent tropical systems to track at the moment. However, there is still the chance that Harvey could try to redevelop over the next few days.
