We may be past the autumnal equinox, but Monday clearly looks to have missed the memo as it brings back a bit of summer before temperatures fall back below normal later this week. Dry air will keep skies mostly clear, and a bit of shortwave ridging will help highs top out around 90° in the afternoon after starting the day in the upper 60s to around 70° at the coast. From there, though, changes will be afoot as high pressure anchored in New England starts to wedge into the area beginning Tuesday. This will drive high temperatures from the mid-80s on Tuesday to the low 80s by Wednesday, with below-normal highs lasting into the weekend. A trough developing offshore will help keep shower chances in play for much of the week, primarily in the afternoons, though it’s worth noting that we’ll likely get some sunshine in as well at times. Northeasterly winds will turn breezy as we head into the second part of the week, and this could drive some coastal flooding concerns through the weekend. Some of the guidance is spitting out some fairly high tides, but it’s also worth noting that this guidance isn’t really that awesome and often goes to extremes. Keep an ear out for Coastal Flood Advisories from the National Weather Service.
We’ll continue to deal with the fringes of Tropical Storm Ophelia on Saturday, though the weather will be gradually improving as time goes on. We’ll see a mix of sunshine and cloud cover, and northwest to westerly winds will still be a little elevated. However, as the day goes on and Ophelia moves further away, we’ll see those winds slacken and some of that cloud cover begin to break a little. The cooler and drier air wrapping around Ophelia will keep temperatures on the low side, with highs topping out in the upper 70s after a comfortable start in the low 60s.
Ophelia will have exited the weather picture on Sunday, and we’ll see much more sunshine and, overall, a warmer day as a result. Expect highs to top out in the mid-to-upper 80s after starting the day in the mid-60s. Winds will have backed down to generally light speeds, too, making for a nice day to get outside a bit. Try to take advantage, if you can!
The weather for Friday and at least the first part of the weekend will be dictated in part by Potential Tropical Cyclone Sixteen, which is forecast to become a tropical storm — probably named Ophelia unless an Atlantic wave develops faster than forecast — as it approaches the NC Outer Banks this weekend. We will stay well on the western periphery of the storm and only feel the occasional shower on Friday, with a gusty breeze for most of us. It will be a rough go at the beaches — probably not the best day to go with gusty winds, high surf, rip currents, and some afternoon coastal flooding around the 1:45 PM high tide. Erosion is certainly not out of the question as well. Highs on Friday top out in the low 80s.
Showers depart by Saturday as maybe-Ophelia moves northward away from us. We start the day in the low 60s with temperatures heading into the low 80s once again under mostly cloudy skies. We should see some breaks in the clouds develop particularly as we get later into the day, though. Winds will remain somewhat breezy, but not to the degree we’ll see Friday.
Sunday is the pick day of the weekend as far as outside stuff goes; lows in the low 60s give way to highs in the mid-80s under mostly sunny skies. Another plus to Sunday: Winds will have tapered off considerably, too, as maybe-Ophelia loses tropical characteristics around the Delmarva Peninsula.
Rain-free conditions come to an end Thursday as we should see some scattered showers from time to time courtesy of developing low pressure well offshore. We’ll get off to a much warmer start than the previous couple days, with lows across the metro in the upper 60s to around 70°. Expect a scattering of showers and maybe some rumbles of thunder throughout the day, coming ashore within onshore flow. A few heavy downpours can’t be ruled out. Highs top out in the low 80s.
We’ll get close to coastal flood stage with Thursday afternoon’s high tide, forecast to peak around 12:41 PM, thanks to the increasing northeasterly flow, which tends to pile water up quite efficiently, so we’ll need to keep an eye on that in case some salt water works into the area.
The rest of the work week will turn somewhat unsettled as a coastal low spins up later this week into the weekend. Wednesday still looks good, though, with seasonable warmth in the mid-80s under partly cloudy skies in the afternoon. We could see a couple isolated thunderstorms pop on Thursday as onshore flow becomes a little more pronounced as a coastal trough sharpens nearby. Temperatures will start in the mid-60s and top out in the mid-80s in the afternoon.
Friday is when we should start to see winds begin to kick up at the coast as the pressure gradient between low pressure developing offshore and high pressure over New England begins to tighten. The stronger onshore flow as well as a scattering of showers and a few thunderstorms will keep highs in the mid-to-upper 70s. Yes, there is still a low chance that this system could attain some tropical characteristics, but it’s not something I’d be overly concerned with. Could make for a less-than-ideal weekend at the beaches, though. Stay tuned to forecast updates as we get closer to the weekend.
