We’ve got one more generally quiet day of weather coming up for Tuesday before turning a little more unsettled heading into the second half of the week. Temperatures will remain around if not a touch below normal as a solid onshore breeze keeps us on the “cool” side. We’ll see a few clouds from time to time, but overall, expect a mostly sunny day. The only downside to the onshore flow will be a moderate risk of rip currents at the beaches, so be alert if you are going to be heading into the surf.
The rest of the work week will generally trend warmer and stay mostly rain-free, especially the further inland you are. Expect generally partly cloudy skies Wednesday, though we’ll see a disturbance swing through later in the day that’ll add some high cloud cover to the mix. Expect highs to top out in the upper 80s to around 90° after a start around 70°.
The aforementioned disturbance in association with the stalled front nearby could kick up some stray showers and thunderstorms on Thursday, especially near the coast. Most locations inland of 17 could have a brief window for a storm or two Thursday morning, but the vast majority of us should get the day in rain-free. Temperatures get a little warmer, with a low 70s start yielding to highs in the low 90s.
The disturbance and associated low is out of here by Friday, yielding a warm and mostly sunny day. Once again, we start in the low 70s, warming to the low to mid-90s in the afternoon. We’ll keep this warming trend going into the weekend, with upper 90s possible on Saturday.
It’s a low bar to clear, but Tuesday will be much quieter than Monday was weather-wise as drier air noses in from the northeast. This should be enough to keep storms, much less significant cloud cover, at bay for a day. We start the day in the upper 60s to around 70°, warming to about 90° in the afternoon under mostly sunny skies. Unfortunately, we’ll need the good weather for some cleanup after severe storms brought large hail and damaging winds to the Summerville area on Monday evening.
Scattered thunderstorms return to the forecast on Wednesday afternoon, once again focusing inland along and ahead of the seabreeze. It’ll be another mild start around 70°, warming to near 90° in the afternoon. Dewpoints around 70° will help drive heat indices to around the low to mid-90s.
Thunderstorm chances peak Thursday ahead of a cold front. Expect scattered to numerous storms to develop ahead of the seabreeze first as temperatures head to the mid-90s with dewpoints in the low 70s. Heat indices should crack 100° in the afternoon, so if you have outdoor plans, be ready to move those indoors. Thunderstorm chances will approach the coast later Thursday evening into the overnight as the front draws closer, and a stronger storm or two can’t be totally discounted. Be alert to quickly changing conditions if your Thursday night includes some out and about time.
The front clears the area Friday. It won’t get cooler, but the dewpoints will be dropping throughout the day, so while highs top out in the mid-90s once again, we shouldn’t see the heat indices we saw on Thursday. A stray storm might be possible in the afternoon, but all in all we should see plenty of sunshine and a rain-free day for many.
Warm and muggy conditions can be expected for the rest of the work week, with some periods of thunderstorms possible especially Wednesday and Thursday.
Tuesday starts around 70° and warms to near 90° in the afternoon. A few thunderstorms will be possible, particularly further inland near the I-95 corridor. Not everyone will see storms, and the Charleston metro area in particular should be clear of any unsettled weather by evening in the wake of the seabreeze.
Disturbances aloft working with ample instability will maximize shower and thunderstorm chances Wednesday and Thursday. The best risk for storms will be during the afternoon and evening hours. Severe weather isn’t expected, though storms could pack some gusty winds where outflow boundaries collide. Temperatures Wednesday top out once again near 90°, while we turn even warmer on Thursday with highs in the low to mid-90s. Given dewpoints in the low 70s, we could get close to heat indices around 100°.
A front approaches the area on Friday, but drier air will be working its way in, so while temperatures will be similar to Thursday (low to mid-90s), dewpoints will be trending lower. This should also keep the thunderstorm risk a little more at bay, leading into a generally quiet weekend.
Quieter weather looks to generally be in store for the rest of the abbreviated work week as temperatures run on a cooling trend heading toward the weekend (and the end of May). We start Wednesday in the mid-to-upper 60s, warming to around 90° in the afternoon. Yes, still quite warm, but with some drier air aloft mixing dewpoints down to the mid-50s, relative humidity values will be in the 30-45% range. Expect just a few clouds from time to time with no expectation of any seabreeze showers or thunderstorms.
A bit more in the way of cloud cover arrives Thursday into Friday as a weak front approaches. Thursday’s highs run in the mid-to-upper 80s, while Friday’s highs run solidly in the mid-80s. Showers don’t appear likely, but can’t be totally ruled out with the frontal passage later Thursday into Friday. Dewpoints remain reasonably tame, though slightly cooler temperatures will elevate the relative humidity a little bit. All in all, not a bad end to May (and climatological spring).
The forecast for the rest of the work week is fairly straightforward: Partly cloudy to mostly sunny skies with temperatures gradually getting warmer (with dewpoints unfortunately following suit) as time goes on. Wednesday will feature one more cool start in the low 60s before warming to the mid-to-upper 80s in the afternoon. Dewpoints will mix out to the low 60s, so it won’t feel too bad. They’ll start to climb into the upper 60s on Thursday, though, as highs reach 90° in the afternoon. With the additional humidity, expect heat indices to run a few degrees warmer. Friday continues the warming trend, with highs once again in the low 90s and dewpoints creeping up even further to the 70° mark making for another warm and muggy day.
While the rest of the work week looks to remain rain-free, slight shower and thunderstorm chances will figure into the forecast as we head into the Memorial Day weekend. It doesn’t look like a rainout, but you’ll want to have indoor backup plans in case thunderstorms threaten.
Finally, a programming note: I’m taking the next few days off for some much-needed downtime. Posts will be scattershot at best. As always, the latest NWS forecast is on the chswx.com homepage. See y’all next week!
We have another nice day ahead Tuesday. We’ll start the day in the low 60s once again, with highs topping out in the low-to-mid-80s under mostly sunny skies. It’ll be a touch breezy, with winds out of the northeast once again around 10 MPH, but this is what’s keeping us a little on the cooler side, so we’ll take it.
The only weather concern will be the risk for water levels peaking in minor flood stage again with the Tuesday evening high tide. Minor coastal flooding looks probable between 7-9 PM with water levels peaking around 7.1’. It’ll be enough to cover the more vulnerable roads once again with salt water, but it won’t be a widespread issue.
Expect generally quieter but warmer conditions for the second half of the work week as high pressure gives us a respite before another unsettled period commences Saturday.
Wednesday will feature a mix of clouds and sun that’ll help drive temperatures into the mid-80s in the afternoon after a start near 70°. A few showers and thunderstorms will be possible in the afternoon and early evening as a weak front moves through the area, and a strong wind gust or two can’t be ruled out in the stronger storms.
High pressure is the main weather driver on Thursday, yielding a fairly quiet and warm day across the Lowcountry. We’ll start the day in the mid-to-upper 60s, warming to the mid-to-upper 80s in the afternoon with just some passing clouds from time to time. Friday should remain mostly quiet with temperatures once again starting in the mid-60s before yielding to mid-80s in the afternoon. High pressure will be departing ahead of our next disturbance, and there’s still some question as to how soon showers and thunderstorms arrive in the area as a result. So, for now, there’s a slight chance we could see some activity Friday night, but it’s more likely that unsettled weather holds off until Saturday.
Tuesday figures to be a fairly active weather day with a couple rounds of storms expected. The first one will be ongoing as we wake up and commute; periods of heavy rain will be possible within thunderstorms, so be ready for delays in the morning. One other twist will be in the form of a warm front that will lift north across the area as we get into mid-morning; this could enhance low-level shear enough where the environment might support a brief tornado (though this risk is fairly low all things considered). The first round of showers and thunderstorms should get offshore roughly around midday, and many of us will catch a break from the rain early Tuesday afternoon. Heading into mid-to-late afternoon, expect additional scattered showers and thunderstorms to fire across the area. There will be a damaging wind risk within the strongest storms, so you’ll want to keep an ear out for possible weather warnings. Storms will be possible well into the evening before chances head back down around midnight or so.
Temperatures Tuesday start on the warm and muggy side in the mid-to-upper 60s. Expect highs to top out in the low 80s given the expected showers, thunderstorms, and overall cloud cover.
