Thursday: Sun’s back

/ January 31, 2024 at 7:29 PM

The sun comes back out on Thursday with the upper low long gone, and this leads to a nice warmup for Thursday. After starting the day in the mid-to-upper 30s, we’ll warm to the low-to-mid-60s for the start of February. Overall, no major weather concerns to kick off the month, and that ain’t bad.

Rest of the work week: A few showers Wednesday morning, but quiet thereafter

/ January 30, 2024 at 6:00 PM

Generally quiet weather continues for the balance of the work week. The exception will be Wednesday morning, when a little bit of energy aloft traverses the area and squeezes out some shower activity. Rain gauges won’t catch much precipitation at all, and it should be out of here by afternoon. Clouds could hang around, though, and some cooler air blowing in behind the disturbance will keep highs pinned to the mid-50s Wednesday afternoon.

High pressure — and, as a result, sunshine — returns to close out the work week. Expect mostly sunny skies on Thursday. After a seasonably cool start in the upper 30s, highs will warm to the mid-60s in the afternoon. Friday is still looking good, too, with low 40s yielding to upper 60s in the afternoon under partly cloudy skies, so if we get stuck in a temporal loop, at least the weather will be nice.

Peeking ahead at the weekend, we see a quiet and seasonably warm Saturday but an increasingly unsettled Sunday as another storm system approaches the area. This storm system peaks overnight Sunday into Monday with decent rainfall expected. Rain chances diminish heading into next Tuesday, with a little bit of a chill in the air as well.

Tuesday: Quiet and seasonable conditions

/ January 29, 2024 at 7:05 PM

Expect another seasonally-appropriate day on Tuesday, though we will start out a little cooler than we did on Monday. Lows should bottom out in the mid-30s, and with a little wind still blowing, it’ll feel a few degrees cooler. Temperatures should head to the low-to-mid-60s under mostly sunny skies. Winds will shift southerly and pick up a bit in the afternoon ahead of a weak low, nudging dewpoints up a few degrees but certainly nothing outrageous.

The week ahead: More seasonable temperatures than last week

/ January 28, 2024 at 11:06 PM

Temperatures will be much more seasonable this week as a trough re-establishes itself in the east over the next few days, though we will still run a couple degrees above late-January and early February normals (highs generally in the low 60s). Weather will be generally quiet this week as generally dry air and surface high pressure generally rules the roost. The main exception will be Wednesday as an upper low dips nearby, instigating surface low pressure across the Carolinas, but even then the risk for showers will be generally very limited given the dearth of moisture. Quiet weather resumes Thursday through Saturday before another storm system develops in the Gulf of Mexico and strafes the area to the south. Drier air will again limit our rainfall potential, but we will turn a little cooler heading into next week as another upper low lumbers through the area.

Weekend forecast: Unseasonable warmth comes to an end

/ January 26, 2024 at 5:56 PM

After setting a daily high temperature record and tying the monthly high temperature record for January today, we have one more warm day for Saturday before a front brings temperatures back down to earth on Sunday. We start Saturday in the low 60s once again before warming to the mid-to-upper 70s in the afternoon. Scattered showers should be a factor ahead of the aforementioned front, but coverage won’t really amount to much until we get into the overnight as the front moves by. Showers will taper off early Sunday morning, and as cooler and drier air moves in behind the cold front, cloud cover will break up. Temperatures will be held to the mid-to-upper 60s as gusty west winds — perhaps with gusts approaching 30 MPH in the early afternoon — blow into the area. More normal temperatures return for next week, with a stretch of quiet weather expected to close January and start February.

Friday & the weekend: Warm with occasional showers and maybe some thunder

/ January 25, 2024 at 5:45 PM

More warm and occasionally unsettled weather is on the way for Friday and the weekend. Lows will continue to run where January normal highs should be, and highs will still run well above normal, especially Friday and Saturday. In fact, Friday’s forecast high of 78° gets close to the record high of 80° set in 1950. The warm starts will lend themselves nicely to fog potential in the mornings, and sea fog may be persistent throughout the day as the warmer air overtops the much cooler waters.

Showers remain in the forecast as well as we stay within the warm sector of a stalled out frontal system. Friday could even feature a few thunderstorms, but severe weather is not anticipated. Saturday will once again feature a scattering of showers and maybe a rumble of thunder as well. A stronger front will push into the area on Sunday, pushing through later in the day to clear us out and cool us off. Showers and a few thunderstorms will be possible ahead of this front as well early in the day, but once the front is through — generally thinking early to mid-afternoon — the shower threat will end, cloud cover will decrease, and dewpoints will begin to fall.

Much more seasonable weather returns to the area starting Monday, with generally quiet conditions through at least Thursday.

Thursday’s forecast: Another unseasonably warm day with showers

/ January 24, 2024 at 8:06 PM

We hit 77° at the airport on Wednesday, narrowly missing a record high by two degrees (79°, set in 1950 and tied in 1974) and making this the warmest day so far in this young year. We have a chance to top that on Thursday despite showers working their way into the area as we stay within the broad warm sector of a storm system in the mid-South. We should start the day with some patchy fog as lows fall to the low 60s, right around the normal high for this point in the year. Temperatures will then warm to the upper 70s, and there’s a more-than-decent shot that some spots reach 80°. (The record high for January 25 is 82°, set in 1949.) A few showers will be possible across the area during the day, but coverage should be relatively sparse.

Rest of the work week: Unseasonable warmth continues with some showers mixed in

/ January 23, 2024 at 7:01 PM

The warming trend continues Wednesday as a warm front lifts north of the area. Temperatures start in the mid-to-upper 50s owing to cloud cover blanketing us for much of the night. Once the warm front shifts ashore and winds go southeasterly, temperatures will respond further and head to the mid-70s. It’ll be kind of muggy, too, with dewpoints in the mid-60s expected behind the warm front. Scattered showers will remain possible throughout a fair bit of the day, though we should see more sun than we did Tuesday (not hard to do, tbh).

At a minimum, we’ll get the first part of Thursday in rain-free, if not the vast majority of it, before a front approaches the area and reintroduces shower and storm chances for Friday. Temperatures will peak Thursday, with lows in the low 60s and highs topping out around the mid-to-upper 70s. There will be a chance for a few showers late, but most of us should stay out of that until Friday, when shower coverage looks to increase with some thunder possible as well. Severe weather currently doesn’t appear to be a concern, though, as wind fields are largely unimpressive and instability appears meager. Temperatures on Friday will be tamped down a little by the shower activity, “only” reaching 75° after starting in the low 60s once again. We stay in the 70s on Saturday, but a second, stronger front will restore order to temperature chaos on Sunday, and by Monday, expect temperatures near normal with much more sunshine.

Tuesday: Warming trend continues, maybe a few showers

/ January 22, 2024 at 6:45 PM

After a day in which we warmed up some 14° compared to Sunday with a high of 60° at the airport, the warming trend continues for Tuesday and beyond as surface high pressure continues to move offshore. Temperatures on Tuesday start in the low-to-mid-40s — roughly where we were for a high on Sunday — and warm into the mid-60s in the afternoon under mostly cloudy skies. A few showers will be possible at times, but any rain will be generally light. Still, y’all know how traffic can get even with the lightest of rain, so prepare accordingly.

The week ahead: Decidedly warmer, but showers hang around

/ January 21, 2024 at 10:58 PM

After a quite chilly weekend, we will be thawing out very quickly as we get into the new work week. Monday gets off to one more frigid start with lows in the mid-20s. From there, though, we start to see the arctic airmass begin to modify as a ridge builds aloft and surface high pressure shifts offshore. Monday’s high goes into the mid-50s, much warmer than we were at any point over the weekend. Then it gets downright spring-like: Tuesday warms into the mid-60s after a mid-40s start, and by Wednesday we’re in the 70s. Mid-70s take hold Thursday through Saturday ahead of a cold front, which should help to bring temperatures down a touch by Sunday.

The only fly in the ointment will be scattered shower chances beginning Tuesday and really lasting for the next few days as we sit between an upper trough to the west and ridging to the east. This will transport moisture and occasional upper-level disturbances into the area, and a surface trough along the coast will help act as a focal point for shower development. It won’t rain all the time or all day at any one spot, but all the same you’ll want rain gear handy just in case, especially heading into the weekend as the aforementioned front approaches.
