Despite a little more cloud cover, expect temperatures to run a little warmer Tuesday in part due to a little more moisture being available and the overall modification of the airmass that settled in behind the front last week. Temperatures will still run generally around, if not slightly below, normal for mid-May, with cooler air at the coast keeping highs at the beaches in the 70s.
Despite high pressure continuing to build across the area, one cannot totally rule out a shower or two developing on the southern extent of the ridge. The better rain chances will be south of us, but a few sprinkles aren’t out of the question. All in all, the vast, vast majority of us stay dry tomorrow — and we’ll stay that way through at least early next week.
A late-season cold air damming wedge will remain in place on Thursday, keeping temperatures well below normal for mid-May and shower chances in place as low pressure develops off the Florida and Georgia coasts. We’ll start the day in the upper 40s to around 50° with highs — provided the wedge scours away a bit — topping out in the mid-60s. That may be generous, though. Breezy northeast winds will continue within the wedge throughout the day with persistent cloud cover. There’s a chance we could see some breaks in the clouds later in the evening, but that’s somewhat up in the air based on how much moisture could be trapped within the wedge.
As mentioned before, scattered showers look probable, with even some drizzle possible especially if the wedge remains entrenched. Suspect that the best rain chances are going to be closer to the coast and will be greatest in the morning. As low pressure pulls away, drier air will punch into the area, but it may take time to erode the layer of overcast just off the surface.
Fortunately, this will be relatively short-lived — clouds will begin to break on Friday, and by the weekend we’ll see mostly sunny skies and temperatures in the mid-to-upper 70s. Hang in there!
We will start Wednesday in the low to mid-60s across the area with showers and maybe a thunderstorm or two ahead of a cold front. Said front will sink southward through the area during the morning, and we will cool off as the day goes on. Expect our high in the mid-60s to be recorded before noon, with temperatures falling into the 50s during the afternoon and evening hours. Rain will be off and on throughout the day, so just be prepared with the rain gear as needed. (You might want to go with something fleece-lined.) Models suggest we may see a little break in the rain as we get into the evening hours once low pressure develops offshore and heads away, which may not be the worst thing for the commute home.
It looks like we will set a new record low maximum temperature on Wednesday. The current coldest high recorded at the airport on May 12 is 69° set in 1963. The current forecast high of 67° will clear that bar fairly comfortably. All will hinge on how quickly the cold front can get through the area during Wednesday morning.
We have one more day in the 80s on Tuesday before a backdoor front sinks south of the area Tuesday evening, bringing quite a cooldown to the area Wednesday and Thursday. Isolated showers and thunderstorms will be possible as the front sags southward across the area, particularly in the afternoon.
Better rain chances arrive overnight into Wednesday, as moisture overruns a weak wedge of high pressure, setting up widespread precipitation for Wednesday and potentially into Thursday. An excessive rainfall event is not expected — indeed, this rain will be quite welcome as we continue to experience abnormally dry conditions across the Lowcountry. The persistent rain falling into the wedge will keep temperatures pinned down in the upper 60s. Record low maximum temperatures of 69 on Wednesday (set in 1963) and 68 on Thursday (set in 1996) are certainly in jeopardy. (At least it’s May and not January, where the wedge is often much chillier and the rain much more unpleasant!)
Temperatures rebound beginning Friday, and we continue to look really good for an extremely pleasant weekend of weather. (It’s never too early to think about the weekend, after all.)
A cold front came through early this morning and you can really feel the difference out there! The air is much drier this morning in comparison to yesterday, with dewpoints down into the upper 50s and low 60s as opposed to the mid-to-upper 60s as they were 24 hours ago. Partly cloudy skies will continue today as low pressure organizes off the coast later today, with a very tiny chance of a shower this evening. We’ll see a second round of dry air punch in overnight, making for excellent weather especially Friday into Saturday.
After the high topped out at 88° yesterday, we look to take at least one step closer to 90° today with another very summer-like day ahead. Humid air will allow heat indices to head up into the mid-90s for the first time this year. We’ll stay dry for much of the day absent any triggers for thunderstorm development, with our best chance of showers and thunderstorms coming later this evening (much like last night). Once again, we’ll be looking to our west throughout the day to nail down timing of any showers and thunderstorms that impact the area. Much like last night, there will be a damaging wind risk as well with the strongest thunderstorms, so keep an ear out to forecast updates throughout the day.
This morning, we find a cold front moving into the Upstate of SC. Said front looks to cross the area this afternoon with mostly little fanfare; expect mostly clear skies by sundown. Despite the front, today will be the warmest day of the week as deep downslope flow in the wake of the front allows temperatures to warm into the upper 80s. Dewpoints will trend downward, though, and it will feel pretty good outside despite the higher heat to close April. The weekend looks pretty good, with an especially nice day coming up on Saturday — more later today!
We’re going to feel a little more like late May than late April tomorrow as high pressure slides a little more offshore with strong ridging remaining aloft. Humidity creeps up a little bit, and with a little compressional warming beginning ahead of a cold front, temperatures will get into the mid-80s in the afternoon. We will remain rain-free for at least one more day given the ridging aloft; with only a slight chance of thunderstorms on Friday as the front swings through, it is conceivable we will stay rain-free through the weekend as high pressure builds back in behind it, cooling things off a little for Saturday.
Minor coastal flooding will remain an issue with the evening high tides through Friday. Winds will then shift offshore and lingering astronomical influences will wane, ending this cycle of coastal flooding.
If you liked today, you’ll like Wednesday — we’ll get back up into the low 80s under mostly sunny skies. Temperatures will run a little warmer in the morning thanks to a little more cloud cover overnight, but will still be largely comfortable around 60°. The warming trend continues into Thursday, when we’ll reach into the mid-80s across the area ahead of a cold front. Said front looks to bring some showers and thunderstorms into the forecast for Friday, but the exact details of how rain will go down are still a little iffy. Stay tuned.
Coastal flooding will remain a concern with the 10:10 PM high tide Wednesday night as lingering astronomical influences and onshore flow persists. We’ll likely have another Coastal Flood Advisory as a result.
We’ve got another nice day ahead on Tuesday with high pressure remaining in control both at the surface and aloft. Temperatures will start in the mid-50s before rising to about 80° in the afternoon (it’ll run a few degrees cooler at the beaches) under mostly sunny skies. There could be a few patches of fog in the morning, but nothing too out of band.
We’ll want to keep an eye on high tide Tuesday evening for another round of minor tidal flooding. High tide is expected around 9:18 PM, and water levels could approach 7.2′. Be ready to reroute in case roads close or are otherwise covered with water.
