Thursday: Another comfortably warm day — minus the wind

/ May 3, 2023 at 11:24 PM

Thursday will represent the peak of our stretch of nice weather for one main reason: the pressure gradient that has kept our winds elevated for several days will finally have relaxed, bringing winds down to a light breeze during the day. Otherwise, it’s a carbon copy of Wednesday: Lows around 50°, with highs in the mid-70s in the afternoon under mostly sunny skies. I hope you can take advantage!

Rest of the work week: Below-normal temperatures continue

/ May 2, 2023 at 9:16 PM

The rest of the work week will continue with plenty of sunshine and below-normal temperatures. We’ll start in the upper 40s to around 50° on Wednesday before temperatures only get up to around the mid-70s despite nearly unfettered sunshine. It will feel quite nice outside, but you’ll still want to mind the breeze that could push 20 MPH at times with higher gusts.

Tuesday: Another bright and sunny — but windy — day

/ May 1, 2023 at 9:38 PM

Tuesday looks fantastic by most objective measures — lows in the low 50s followed by mid-70s in the afternoon with plenty of sunshine. The only fly in the ointment remains the elevated wind gusts that will come along with peak heating in the afternoon thanks to deep mixing of the near-surface air that will tap into some elevated winds aloft. That’s about it, though — will be another pretty day with temperatures that at the end of this month I suspect we’ll wish we had back.

The week ahead: Windy start to May

/ April 30, 2023 at 9:52 PM

May will be getting off to a fairly windy start as a tight pressure gradient features prominently across the Southeast to start the work week. (At least we get comfortable temperatures and sunny skies!)

Weekend forecast: Warm and dry day Saturday, storms arrive in the evening and last through Sunday

/ April 28, 2023 at 10:40 PM

Saturday looks to be a fairly warm and muggy day — a tiny sliver of a summer preview — as we start the day in the mid-60s and top out in the mid-80s in the afternoon. We’ll stay rain-free for much of the day before a cold front and an accompanying upper low starts to get closer to the area. Shower and thunderstorm chances will subsequently increase, and a strong to severe storm isn’t totally off the table later Saturday given sufficient shear. Some heavy rain will be possible overnight and into early Sunday morning as well, with local amounts possibly exceeding an inch of rain before it’s over.

Showers and storms look to be ongoing as we head into Sunday morning, but will taper off as the day goes on as low pressure lifts northeast and the aforementioned cold front moves through. By Sunday evening, we should be largely rain-free and cooling off as a drier airmass builds into the area post-frontal passage. Highs top out around 80° in the afternoon. Winds will be elevated, with gusts 25-30 MPH possible particularly as we get into the afternoon hours as the mixed layer rises to around 6,000 feet, tapping into a decently strong low-level jet, which will hang around for the subsequent few days to provide a gusty start to May.

Friday and the weekend: A few storms Friday, quiet Saturday, then turning busier Saturday night and Sunday

/ April 27, 2023 at 10:48 PM

So one thing you’ll notice out of the gate with Friday’s forecast is that it looks a lot less stormy. This is due to the batch of rain pushing through as of this writing on Thursday evening; once this is through in the early morning, we’ll be in a lull in the more widespread activity, it looks like. Isolated to scattered thunderstorms remain possible, though, particularly further inland. The atmosphere will be primed for some sporadic severe weather if storms can fire given sufficient instability and shear, with damaging winds and hail the main concerns. However, the if in the previous sentence is pretty loaded — some models show very little if any rain during the day Friday. We’ll want to wait and see, and I’ll encourage you to stay weather-aware in case storms threaten, but overall the forecast looks a lot less soggy than it has for a good bit of the week. Highs will top out in the low 80s after starting the day in the mid-60s.

Thursday: Dry start, stormy finish heads into an unsettled weekend

/ April 26, 2023 at 10:34 PM

We should get a fair bit of Thursday in rain-free, but changes will be coming later in the day as low pressure to the west approaches the area. We start one more morning in the upper 50s before a warm front gradually lifts through the area throughout the day, which will bring dewpoints up in the afternoon and put a little mugginess in the air. A shower or storm along the seabreeze in the afternoon and early evening can’t be totally discounted, but the bulk of the rain arrives after dark with the aforementioned low pressure and will be around for much of the overnight.

Rest of the work week: Turning unsettled with periods of showers and storms

/ April 25, 2023 at 7:17 PM

We’ll see steadily more unsettled weather as we head into the second half of the work week as a series of storm systems impacts the area.

Tuesday: One more largely quiet day before showers return to the forecast

/ April 24, 2023 at 10:45 PM

We should get much of, if not all of, Tuesday in rain-free before the pattern changes to something more unsettled to finish up the work week. We start Tuesday in the mid-50s; cloud cover and continued northeast flow will inhibit temperatures from rising much higher than the mid-70s in the afternoon. Some of the higher-resolution guidance has some isolated to scattered showers breaking out later in the afternoon into the evening hours as high pressure loses its grip on the area, but not everyone will see rain.

/ April 23, 2023 at 5:29 PM

We get the week started with quiet, if not somewhat cloudy, conditions across the area. We then turn more unsettled from Wednesday on.
