We will get off to an unsettled start to the weekend as a frontal boundary sags south into the area during the day on Saturday. Ahead of the front, expect highs to top out in the low 90s before numerous showers and thunderstorms develop across the area. Chances are pretty good that you’ll see at least a little rain at some point tomorrow. With plenty of available moisture to wring out, though, it is conceivable that flooding may be a concern tomorrow within the strongest storms. While severe weather looks unlikely, all storms are dangerous due to the lightning they produce. When thunder roars, go indoors!
It’s expected that the front will pass through and stall out to our south by Sunday. Temperatures will run a little “cooler” with highs topping out in the mid-80s, but scattered showers and thunderstorms should still develop in the afternoon. How Sunday ultimately evolves will depend on what goes on during the day Saturday, so keep an eye out for forecast adjustments.
Summer heat will make its debut this weekend as high pressure at the surface and aloft dominates the weather picture. We’ll begin to feel a little of this on Saturday, but onshore flow will help keep temperatures capped in the mid-80s given a progressive seabreeze in the afternoon. Winds turn more westerly on Sunday, which will hinder the seabreeze’s inland progress and allow temperatures across much of the metro area to reach the low 90s for the first time this year. Temperatures will run cooler at the beaches — think upper 70s on Saturday and mid-80s on Sunday. The ridge aloft will keep a strong lid on any thunderstorms that try to fire, so don’t count on any rain over the weekend heading into the next several days. We look to get even hotter heading into the work week as the blocking pattern aloft looks to hang around for several more days.
We’ve got a good-looking weekend queued up to start May. A cold front came through earlier today, and drier air is moving into the area from the north. This will make for a comfortable start to Saturday, with lows bottoming out in the mid-50s. Temperatures will rise into the mid-to-upper 70s under a mostly sunny sky — a really great day to get outdoors. Sunday will turn a little warmer with highs topping out in the low 80s under partly cloudy skies, but should still be quite nice.
As we get into next week, the pattern turns a little more unsettled with shower and thunderstorm chances each day through Thursday, though this should all settle out for another gorgeous weekend afterward. Enjoy!
As I mentioned last night, the weekend’s forecast remained a bit fluid and there could still be changes. As time has gone on, we’ve seen a more southward trend to this weekend’s rainfall chances as drier air looks to hold on a little more tightly across the area. Thus, shower chances remain generally low as the target timing for showers generally lies between Saturday afternoon and Sunday morning. Looking at the data coming in right now, it certainly looks like Sunday morning may be the better opportunity for some showers to come through, but rainfall amounts look light.
Temperatures will continue to run a little cooler than normal across the area with more cloud cover than sun, but mid-70s won’t feel too bad, either. All in all, it’s not the best weekend of weather we’ve ever had, but it could be a lot worse, too.
After very likely setting a new record low maximum temperature today with a high so far of just 53°, our cold snap continues into tonight and tomorrow. A Freeze Warning is in effect for the Tri-County tonight as temperatures are expected to dip below freezing for at least a little while particularly inland and in sheltered areas. The record low of 33° at the airport, set in 1962, certainly seems in jeopardy to fall. Even where temperatures don’t drop below freezing, there is some potential for frost. Wherever you are, protect plants and pets tonight!
Saturday afternoon should see high temperatures run about 9-10° warmer as the trough that brought us this cold snap moves well away from the area and the April sun angle is able to modify the airmass. We’ll keep high pressure firmly in place at the surface, and that should yield an exceptionally nice spring day with highs in the low 70s in the afternoon.
Beyond the weekend, temperatures will gradually warm to the low 80s by the middle of next week. We’ve got a pretty decent dry stretch ahead of us before our next storm risk arrives for next weekend. Enjoy, and stay warm!
High pressure will assert control of the weather through the weekend. It’ll be chilly out — highs in the low to mid-50s and lows around or below freezing will be common — but the sun will be shining, and that alone is worth celebrating. Have a great weekend, everyone.
A cold air damming regime will remain in place over the weekend, with plentiful moisture and upper-level energy keeping numerous showers in the forecast along with chilly temperatures. This rain will be no joke — NWS is forecasting 1-3″ across the area by Monday morning, with the higher rain totals generally to be found inland of 17. The wedge of cold air nestled between the Appalachians and the Atlantic and its associated persistent overcast will keep temperatures well below normal (62° is the normal high for this time of year).
Despite what some weather apps were showing this time last week, no precipitation type issues are in the forecast this weekend as the core of the coldest air remains well to our north and west.
Showers, overcast, and chilly temperatures will continue on Saturday. The best rain chances will come in the afternoon into Saturday night as some upper-level energy and a surface low pressure system traverse the area. The weather improves Sunday as low pressure moves away from the area, yielding to high pressure building back into the area from the northwest. Cloud cover will scour out, allowing temperatures to rise into the mid-to-upper 50s across the area with ample sunshine throughout the day, giving you a great excuse to skip the 12 hours of Super Bowl pregame shows and get outside for a bit.
There will be an outside shot at some minor coastal flooding very early Sunday morning (high tide ~4:01am) as low pressure deepens off the coast. The current tide forecast peaks around 6.9’, which could be just enough to put some salt water on Hagood Ave. at Fishburne. Given the early hour on a weekend, it should not have major impacts on travel. We remain at five total coastal flooding events (tide levels at or above 7.0’ mean lower low water) so far in 2021.
Get ready for a hard freeze tonight as temperatures plummet into the low-to-mid-20s pretty much everywhere inland of the immediate coast, where temperatures will still likely reach freezing. While winds will die down a little, there will still be enough to send wind chills into the upper teens for Saturday morning. Protect plants, pets, pipes, and people tonight.
Saturday will be another day where temperatures struggle into the mid-40s despite full sunshine. After another freeze Sunday morning, temperatures will begin to moderate, topping out in the mid-50s in the afternoon with plenty of sunshine to continue.
If you want to get outside a bit this weekend and enjoy some legitimate sweater weather, Saturday is the day to do it — we’ll have a mix of sun and clouds with highs topping out in the mid-50s. Rain should hold off until after midnight, with periods of showers in the cards for Sunday. It’ll be a touch warmer despite the rain, but temperatures will continue to run below normal through the last shopping weekend before Christmas.
