Overview: A Slow Soaker With Some Storm Risk
A sluggish low-pressure system is bringing widespread, soaking rain to the foothills of western North Carolina this week. It’s a classic spring setup: deep tropical moisture flows in from the Gulf and Atlantic, slams into the mountains, and dumps several inches of rain over a couple of days. From Alexander to Polk Counties—and everywhere in between—residents should brace for a soggy stretch through midweek.
Rainfall totals between 3 and 5 inches are likely, with localized higher amounts near the Blue Ridge. Flash flooding is a growing concern, mainly in low-lying areas, poor-drainage spots, and near creeks and streams. This is NOT another Helene situation. While rain is the main story, we also can’t rule out a few stronger thunderstorms, some with gusty winds or even a brief tornado on Monday.
Temperatures will start the week well below normal, but we’ll see gradual warming and clearing by Wednesday as the system lifts out and drier air moves in.
Monday: The Wettest Day, With Flooding Concerns and a Storm Risk
Monday brings the brunt of the rain. Steady, soaking downpours are expected much of the day, with embedded thunderstorms possible. This is the type of rain that can last for hours—perfect for staying indoors if you can.
Rainfall could exceed 3 inches in some places just by the end of Monday, especially along the eastern slopes of the Blue Ridge. With that much water coming down in a short period, flash flooding is possible. Low-lying areas, urban drainage basins, and creeks will be most vulnerable.
On top of the heavy rain, there is also a risk for isolated strong to severe thunderstorms. If we get any breaks in the clouds this afternoon that allow warmer, more unstable air to build in, a few storms could rotate. That means there’s a low-end risk for a quick tornado or damaging wind gusts later today, especially in areas that briefly warm up before the next round of rain. Many will not see any sunshine, keeping the severe weather risk at bay.
Highs today will struggle to reach 70°, and many foothill communities may stay in the 60s. It’ll feel more like early spring than mid-May. Expect the rain to taper to scattered showers overnight, but wet conditions will persist into Tuesday.
Safety Reminder: Never drive through flooded roads. Just a foot of water can float a car. “Turn around, don’t drown.”
Tuesday: Lighter Rain, A Few Thunderstorms, and Milder Temps
Tuesday won’t be as intense as Monday, but it still won’t be dry. We’ll see waves of showers through the day, especially in the morning and then again in the afternoon. A few thunderstorms may develop as the air warms up during the day, though these are expected to be garden-variety storms—not severe.
Rain amounts on Tuesday will be lower, generally around a quarter to half an inch, with some locally heavier totals under stronger cells. With the ground already saturated from Monday’s rain, even modest rainfall could keep creeks and streams running high. However, the overall flooding threat should begin to decrease by late Tuesday.
Afternoon highs will rebound into the low to mid 70s—still slightly below average, but noticeably milder than Monday. Showers will gradually taper off into the evening.
Wednesday: A Transition Day—Drying Out and Warming Up
By Wednesday, we finally begin to transition into a drier and brighter pattern. Lingering morning clouds and spotty showers are possible, but the rain should become increasingly isolated as the day progresses. Many locations could go the whole day without measurable rainfall.
Skies will start to clear, especially in the afternoon. With a bit of sun and some drier air moving in, temperatures will climb into the mid to upper 70s—near or even slightly above normal for this time of year. It will feel much more pleasant and spring-like.
By Wednesday night, skies will turn mostly clear, and any remaining showers should fade. This marks the beginning of a much-needed dry stretch, just in time for the second half of the week.
Looking Ahead: Dry and Warm by Thursday, Storms Return Late Week
Thursday looks beautiful—mostly sunny skies, highs in the 80s, and dry air in place. It’s the kind of day you’ll want to spend outside after several days of clouds and rain.
Looking toward Friday and the weekend, another system may approach from the west, bringing back the chance of scattered showers and thunderstorms. Some of those storms could be on the stronger side, but we’ll fine-tune that forecast later this week.
Final Thoughts
This is shaping up to be one of the wetter stretches we’ve seen in a while across the foothills. Flooding, especially Monday into Tuesday, is the biggest concern—so please stay alert and don’t take chances with high water. Thunderstorms may also bring a few surprises today, so make sure your weather alerts are turned on.
The good news? After this dreary start to the week, brighter skies and warmer temps are on the horizon. Hang in there and stay safe!
