Severe Weather Risk Today: Marginal (Main Risk: Damaging Winds)
Detailed Meteorological Discussion
A spring-like weather pattern continues to evolve across the southern Appalachians, with western North Carolina positioned within a warm, increasingly moist southwest flow regime ahead of a slow-moving frontal boundary approaching from the west. The broader synoptic pattern features a developing trough moving across the central United States while ridging remains positioned along portions of the Southeast coast. This setup is allowing warm Gulf-modified air to surge northward across the Carolinas, resulting in temperatures well above early March climatological averages.
Surface observations and model guidance indicate strong warm air advection occurring across the region this morning, with temperatures expected to rise into the mid to upper 70s across much of the foothills this afternoon, with some locations across Cleveland and Rutherford counties potentially approaching near 80 degrees.
The primary forecast challenge today centers around convective development associated with increasing instability and embedded shortwave energy translating through the southwest flow aloft.
Forecast soundings suggest modest destabilization through the afternoon as surface temperatures warm into the 70s while dew points climb into the mid- to upper 50s. This will likely support moderate surface-based instability, though values remain somewhat limited compared to more classic severe weather setups.
Meanwhile, mid-level winds are forecast to strengthen through the afternoon as a weak impulse approaches the southern Appalachians. This will introduce modest deep-layer shear, which may allow for some storm organization should thunderstorms develop along the Blue Ridge escarpment.
Orographic lift along the mountains will serve as a primary forcing mechanism for convective initiation during peak heating.
Radar-based projections and convective-allowing guidance suggest the following general evolution through the day.
Morning (8 AM – Noon)
The morning period should remain relatively quiet across much of the foothills. While isolated showers may develop near the higher terrain, coverage should remain minimal with most areas experiencing partly to mostly cloudy skies.
Early Afternoon (12 PM – 4 PM)
As surface heating increases, isolated thunderstorms may begin developing along the Blue Ridge as instability increases. These storms would then track eastward into portions of McDowell, Burke, Caldwell, and Rutherford counties.
Storm coverage during this time frame is expected to remain isolated with probabilities around 20 percent.
Late Afternoon and Evening (4 PM – 8 PM)
This time period represents the highest probability for thunderstorm development as additional forcing associated with the approaching disturbance moves into the region.
Storm coverage may increase to scattered levels around 40 percent, with storms generally moving east or northeast across the foothills.
Severe Weather Potential
Western North Carolina remains within a Marginal Risk for severe weather today. A marginal risk classification indicates that isolated severe storms are possible but limited in coverage and intensity. The primary hazards with any stronger storms would include:
• Isolated damaging wind gusts
• Small hail
• Brief heavy rainfall
• Frequent lightning
Terrain influences across the southern Appalachians often disrupt organized storm structures as convection moves eastward across the mountains. However, storms occasionally maintain sufficient intensity to produce localized severe wind gusts across the foothills, especially when topographic lift along the eastern escarpment is aided by southeast flow. 850mb southeast winds will drive moisture in from the south and southeast, lift it up the east slope of the mountains, and into a marginally unstable atmosphere. This could allow for the clustering of thunderstorms right along and immediately east of the Blue Ridge late this afternoon, then translating to the northwest piedmont by sunset. Overall, severe coverage should remain very isolated and limited to the strongest areas of convergence, which will be difficult to pinpoint until the event is underway.
Storms today and Sunday may produce localized heavy rainfall. Rainfall totals through the weekend will generally range from 0.10 to 0.75 inches, with locally higher amounts possible during stronger thunderstorms and in locations where thunderstorms cluster and train. Again, chances of widespread flash flooding are limited due to antecedent conditions and streams and creeks running below normal across the region.
Sunday Forecast
Another disturbance embedded within the southwest flow will move across the region Sunday afternoon, bringing another opportunity for showers and thunderstorms. Rain coverage on Sunday may be higher than today, with probabilities near 60 percent across portions of the foothills. Temperatures will remain above average, though slightly cooler than today, with highs generally near 70 degrees.
Early Week Pattern
The pattern briefly transitions toward a quieter regime early next week. Monday and Tuesday should feature mostly dry conditions as weak high pressure temporarily builds across the Southeast. Temperatures will remain mild, with highs generally in the mid-70s.
Midweek System
Forecast guidance continues to indicate a stronger trough approaching the eastern United States by midweek. This system will push another cold front toward the Carolinas by Wednesday and Thursday. Ahead of the front, a strengthening pressure gradient may produce gusty winds across the foothills on Wednesday, along with increasing chances for showers and thunderstorms. Rain chances may peak on Thursday as the frontal boundary moves through the region.
Late Week Pattern Change
Behind the midweek system, a much cooler air mass will move into the Southeast. Temperatures by Friday could struggle to reach the upper 40s to near 50 degrees, marking a sharp drop from the unseasonably warm conditions experienced earlier in the week.
Extended Outlook
The extended forecast suggests temperatures moderating again heading into next weekend, with additional disturbances possibly bringing occasional rain chances.
Our Bottom Line
• Unseasonably warm temperatures today
• Isolated to scattered thunderstorms this afternoon and evening
• Marginal severe weather risk today
• Another round of storms on Sunday
• Quiet start to next week
• Windy midweek system with more rain
• Much cooler air arriving late week
