A strong storm or two is possible Tuesday

/ October 21, 2019 at 11:08 PM

Another cold front will be moving through the area on Tuesday, bringing along some more fall-like weather for Wednesday and beyond. Before it passes, though, we’ll see temperatures spike into the mid-80s with scattered thunderstorms in the area. A few thunderstorms could produce strong, gusty winds in the late afternoon/early evening hours. Be alert to possible warnings.

The front is expected to clear the area around sunset or a little later. Temperatures will cool down nicely behind said front, bottoming out in the low 50s for Wednesday morning.

Our tranquil, fall-like weather will come to an abrupt halt Saturday as the remnants of Tropical Storm Nestor, currently in the Gulf as of this writing, move through the Carolinas Saturday into Saturday night, bringing heavy rain, gusty winds, coastal flooding, and maybe even a tornado or two.

Potential Tropical Cyclone 11 at 12:40 PM.

It’s hard to believe that after the coolest morning since April 27, we are talking about the potential for a little tropical mischief in the Gulf. But, it’s still hurricane season, and this one has a shot at bringing us some much-needed rain over the weekend.

Here comes some legit fall weather, at least for a couple days

/ October 16, 2019 at 11:30 PM

After the wettest day since Dorian, a ridge of high pressure will usher in fall weather for a few days, with the potential for the first 40° readings of the season Thursday and Friday mornings. Then, a slug of tropical moisture will bring in another solid rain chance late this weekend into next week.

A nice weekend concludes; much-needed rain coming next week

/ October 13, 2019 at 7:57 AM

Sunday will finish with a little more warmth than we’ve had the last couple days as high pressure slips offshore and a front stalls out nearby. Clouds will be on the increase throughout the day, but rainfall is expected to hold off until overnight. Highs will top out in the mid-80s; with dewpoints in the 60s, this will feel a little warmer and more humid than we felt on Saturday.

First measurable rain since mid-September at the airport today

/ October 7, 2019 at 1:25 PM
Our stretch of very dry weather comes to an end.

For the first time since September 14, the airport has recorded measurable rainfall. (Traces of rain were recorded September 15, September 30, October 5, and October 6.) As of this writing, a whole one-hundredth of an inch has been recorded at the airport today. (Hey, it’s something.)

One more Augtober day

/ October 3, 2019 at 9:03 AM

We’ve just got one more sweltering Augtober day left before a backdoor cold front swings through the area, cooling us off for the weekend. This will come with a little bit of much-needed rain, too, but don’t expect a washout. After that, another frontal system will usher in a little bit more Fall weather.

The week ahead: An end in sight to Eternal August

/ September 30, 2019 at 5:00 AM

Our abnormally warm and dry September will roll into the first few days of October as strong high pressure aloft remains anchored over the southeast U.S.

Changes are coming, though, and I suspect many of you will be OK with them.

Friday and the weekend: Eternal August continues

/ September 26, 2019 at 10:52 PM

Fall fans, the news isn’t great: Above-normal temperatures will continue for the foreseeable future as a strong ridge of high pressure remains firmly entrenched over the area. A weakening front nearby will help kick off a few showers and maybe a thunderstorm or two across the area. This would be good — it’s been twelve days since measurable rain at the airport — but not everyone is going to get relief. Rain-free conditions move back into the area for the weekend while temperatures in the upper 80s remain more in line with mid-August norms than late September.

Tropical update: Seriously, Karen?

/ September 25, 2019 at 1:32 PM

The tropical Atlantic basin remains fairly active: While Jerry is no longer a tropical cyclone, it continues to spread strong winds and heavy rain across Bermuda. Lorenzo, well out in the Atlantic, has strengthened to a hurricane and is no threat to any land at this time.

And then there is Karen.
