Comfortably warm Sunday ahead

/ April 22, 2023 at 11:54 PM

No weather concerns for Sunday as the cold front has cleared the area, leaving behind a cooler and drier airmass that’ll be highly conducive for outdoor activities. We start the day in the low-to-mid-50s across the area (warmer near the coast). Northwesterly winds, which will have a downslope component from the mountains, will help drive temperatures to the upper 70s in the afternoon under mostly sunny skies. Winds will shift a little more southerly in the late afternoon/evening hours behind the seabreeze, which will nudge dewpoints up a bit, but it’ll still be very, very comfortable outside with low humidity. Enjoy!

Weekend forecast: Stormy Saturday, but Sunday lives up to its name

/ April 21, 2023 at 10:59 PM

A cold front will affect the area this weekend, bringing showers and a few thunderstorms to the area on Saturday before a beautiful Sunday.

Two rounds of precipitation are possible Saturday. The first round could arrive in the morning from offshore, bringing showers and maybe a thunderstorm to the area through mid-morning. It then appears probable that we’ll see a break in the rain for a few hours before the cold front approaches the area later in the afternoon, which will bring the risk for another round of showers and a few thunderstorms. We’ll want to see how many breaks in the clouds can develop midday Saturday, as that’ll have impacts on how much the atmosphere can destabilize. Depending on how unstable things get, we could see a few stronger storms with gusty winds and hail. Wait and see, but be ready for thunderstorms if you have outdoor activities — remember, every thunderstorm is dangerous because of lightning. Highs on Saturday top out in the low 80s after a very warm start in the mid-60s.

The cold front gets through later Saturday, and will yield a beautiful Sunday. We start Sunday in the low 50s before northwest flow drives dewpoints down and temperatures up to the upper 70s in the afternoon. We’ll see a few clouds at most, and it’ll be a great day to get out and about.

Friday & the weekend: Saturday storms lead to a really nice Sunday

A cold front will move through this weekend, knocking temperatures down a peg but also bringing showers and a few thunderstorms into the area on Saturday.

Thursday: Another warm, sunny day

/ April 19, 2023 at 10:28 PM

One more predominantly sunny day is in store for Thursday as stacked high pressure remains in place across the Carolinas. We’ll start the day in the mid-50s, generally around normal for April 20, before warming into the mid-to-upper 80s in the afternoon, which is ten degrees above normal. Unfettered sunshine is expected once again, with very little, if any, in the way of cloud cover. It’ll be another great day to get outside for lunch or even a nice golden-hour dinner.

Rest of the work week: Sunshine continues as warmth peaks Wednesday

/ April 18, 2023 at 10:41 PM

Quiet weather continues through the end of the work week. Wednesday will run quite a bit warmer than the past couple days as stacked high pressure settles in right over the Carolinas. Surface high pressure will slip into the Atlantic during the day Wednesday, turning winds a little more southerly and allowing temperatures to rise well into the mid-80s. The aforementioned high pressure will keep cloud cover to an absolute minimum, much like we saw on Tuesday.

Tuesday: Meteorological brilliance

/ April 17, 2023 at 11:02 PM

Tuesday will be one of those meteorologically brilliant days that will undoubtedly make all of us wish it was the weekend instead. We start the day in fairly crisp fashion with lows bottoming out in the upper 40s to around 50°. High pressure will sit atop the area, and this combined with a very dry airmass will keep the sky unmarred by cloud cover. Temperatures will respond nicely, warming about 30° to the low 80s in the afternoon. Winds will be a little lighter, starting out of the north and swinging around to the northwest, west, and finally south by sunset.

The week ahead: A whole lot of sunshine — and 80s

/ April 16, 2023 at 9:58 PM

There’s not much to write about this week, weather-wise. A cold front coming through overnight Sunday will give way to expansive high pressure that will dominate the weather conversation for the next several days, primarily around just how much sunshine there’s going to be along with above-normal temperatures for mid-late April.

Sunday: Watch for scattered showers and storms, otherwise another warm day

/ April 15, 2023 at 6:30 PM

Sunday will not be rain-free, but it will not be a total loss, either, as a couple rounds of scattered showers and thunderstorms are expected — one in the morning, and then another late afternoon/early evening, with likely some dry time in the middle.

We will likely start the day with some showers in the area as temperatures bottom out in the low-to-mid-60s. These come on the heels of a decaying thunderstorm complex that, as of this writing, is moving over Alabama and the Florida Panhandle. This will pass by mid-morning, and we should see a stretch of reasonably quiet conditions before a cold front gets close to the area later in the afternoon/early evening hours. High temperatures should peak in the low 80s despite an uptick in cloud cover.

As the front approaches, a second round of scattered storms should fire, and a couple of those could be on the stronger side with damaging wind gusts the primary concern. Regardless, if you’re out and about and hear thunder, it’s time to find safe shelter indoors because all thunderstorms are dangerous due to the lightning they produce. This is especially critical for the later shows at High Water.

On balance, nobody will be socked in with rain all day, and some of you may not get any at all! That’s just how this works as we get into the later spring months, after all. The risk for showers and thunderstorms should end by mid-evening, with the front pushing offshore generally before midnight.

From here, beautiful weather ensues for much of the upcoming work week (as seems to be customary in 2023), with the next rain chances not for several days.

Weekend forecast: Sunny Saturday, a few storms Sunday

/ April 14, 2023 at 8:17 PM

Warm weather continues this weekend, with a break in the rain coming Saturday as we’ll sit in-between storm systems. Highs on Saturday peak in the mid-80s after starting in the low 60s, several degrees above normal for mid-April. If you’re headed to High Water, make sure you’re applying sunscreen as the UV index will peak around 9, in the Very High category.

A cold front will approach the area Sunday, bringing with it the risk for some scattered showers and thunderstorms. Guidance is still somewhat mixed on the exact onset of these storms, but expect the best chance for a few thunderstorms in the afternoon and early evening. There is a small risk for a storm or two to produce damaging straight-line winds and some hail. Remember, though: Lightning makes every thunderstorm dangerous. When thunder roars, go indoors! Outside of storms, expect highs to once again top out in the mid-80s.

The front passes by late Sunday/early Monday, and the cooler and drier airmass behind it will bring us a pretty brilliant stretch of weather for the beginning of the work week. But let’s not think about the new work week yet if we can help it. 🙂

Friday & the weekend: Showery bookends to a warm and sunny Saturday

/ April 13, 2023 at 6:30 PM

We’ll see some showers at times over the next few days, but there’s going to be ample amounts of good weather, too — crucial for this High Water Festival weekend.
