Temperature Inversion Explainer
If you happen to have a thermometer in your car (which most modern cars do), have you ever noticed that on a given winter morning when skies are clear, it reads warmer on hills? Then, when you descend into the valleys or are in a very open area that lacks development (such as the Pine Barrens), it is much colder? This kind of early morning can see 20-degree temperature swings across a relatively small region. But… why?
A Mainly Dry and Warm September in the Northeast
What a flip-flop of a month September was! While August gave us the impression summer really wasn’t going to make a comeback, September brought back the real dog days of summer. While we were initially cool with tropical influences, the second half of the month was a near non-stop stretch of warmth and largely dry weather.
First Month of Fall Gets a Summer Finish
The Midwest once again found another month with major temperature swings in September as the transition to meteorological fall began. It was a cool beginning to September as a trough presided in the east with a large blocking ridge in the west. Ideally, this may have been a sign of the end the heat and a move over to cooler fall weather. However, summer decided to make a comeback instead.
First Frost, Freeze, & Snow Dates: Northeast
Despite the best efforts of summer to hold on into fall, cold weather will inevitably prevail across the area once again. Daylight has been decreasing at a rapid rate over the last month and average temperatures have been falling steadily as well. While parts of the interior Northeast have already seen their first frost at the time of this writing (October 6th), most along the coast (including the big cities) have not.
Midwest Average First Frost / Freeze / Snow
The long days of summer have come and gone, and we are now well into Autumn. Pumpkins, Halloween, and changing leaves are just some of the reasons that many people love this season. With all of the great things that come along with Autumn, much cooler air is certainly one of them. Before long, chilly nights and cooler days will begin to settle in. The first frost and freeze of the year typically occur by the end of October or the beginning of November, marking the end of the growing season, and starting the trek through the coldest months of the year.
Superstorm Sandy: 5 Years Later
Half a decade ago, thousands of lives were changed over the course of just a few days.
Record storm surge descended over barrier islands and towering sandbags. Roadways, homes, and even subways were inundated with water. Power was knocked out to millions of people. It would take months to even years for people and businesses to fully recover from what became the second-costliest storm in U.S. history (at the time), but even time couldn't wipe away the memories of one of the most destructive events to ever hit the Northeast.
How Do We Measure Temperature?
You’ve seen it before: on the evening weather report, in your home, on your phone, and even displayed on your local bank’s signage. Temperature is everywhere. It is one of the most crucial points in any forecast. It can determine whether you’re sweating or shivering, or if it’s wet or frozen outside. For the busy person on the go, the temperature can be the difference between a light jacket and a full-fledged parka during the winter.
August 2017: Up and Down End to Meteorological Summer
Dog days of summer? What dog days of summer?
The last holdout of the season for characteristic summer weather didn’t exactly pan out as some typically expect in August 2017. This was not unusual for this year though, especially given the pattern that has dominated over the course of the season. Those looking for extensive, consistent hot and sunny stretches for the last month of meteorological summer were instead left with plenty of storms and temperature swings.
Harvey and Irma Wreak Havoc
Before 2017, the last major hurricane to make landfall in the continental U.S. was Wilma in 2005, leaving some to believe that they were still in the clear while others felt that their time was almost up. Regardless of the odds, there is no real pecking order to where the next tropical system will set its eye on. In fact, from the start of June to the end of November anywhere along east coast of North America and the Caribbean Sea is fair game for the next landfall.
