Closest strike: 8.62 miles Stay Alert! Remain in a safe area until there has been no lightning within 10 miles of this location for 30 minutes. Please be aware that lightning activity can remain high even when a storm is moving away from your location. Even if rain has stopped, do not leave your safe area until WeatherBug indicates that lightning is more than 10 miles away from this selected location. IF OUTDOORS Avoid water, high ground, and open spaces. Avoid all metal objects including electric wires, fences, and machinery. Find a safe area in a building or in a fully enclosed vehicle with the windows completely shut. Unsafe places include underneath canopies, small picnic or rain shelters, convertibles, or near trees. IF INDOORS Avoid water and stay away from doors and windows. Avoid using a hard line telephone. Take off headphones. Turn off, unplug, and stay away from appliances, computers, power tools, and TV sets. Lightning may strike exterior electric and phone lines, inducing shocks to inside equipment.

There is a Marginal Severe Storm Risk for your location.

Large to very large hail and severe winds are the primary hazards. Thunderstorms capable of scattered wind damage are possible in parts of the Carolinas. Dakotas to IA/WI through tonight Radar mosaic this morning shows a bow echo moving eastward along the MN/IA border primarily north of a buoyancy gradient/warm frontal zone. Occasional severe gusts (60-70 mph) have been observed with this MCS the past couple of hours. Expecting more of an east-southeastward motion with the linear system with a continued risk for wind damage before perhaps weakening near the MS River towards midday/early afternoon. Farther west, a belt of south-southwesterly midlevel flow near 50 kt will be maintained from CO to the Dakotas, east of the broad closed low over the northern Great Basin/Rockies. A separate lee cyclone is expected to form in the vicinity of northeast CO this afternoon and then progress northeastward across NE/SD overnight. In the wake of the morning storms, richer low-level moisture will advect northward in tandem with a warm front. Model guidance continues to delay storm development for much of the day as an EML overspreads a destabilizing airmass across the north-central US. A few storms will be possible in ND during the afternoon with perhaps an isolated severe risk developing. Much of the severe threat will likely focus after dark immediately north of the lee cyclone into SD. Westward advection of richer moisture and ascent preceding the surface cyclone (and subtle embedded speed maxima aloft) will likely support elevated thunderstorm development overnight across western SD into southern ND. The environment will favor elevated supercells and small thunderstorm clusters capable of large to very large hail and severe gusts. Farther east, a zone of low-level warm advection will be focused across WI by late evening/early tonight along the northeast edge of the warm elevated mixed layer. Sufficient moistening above the surface and large CAPE will favor the potential for at least isolated large hail/strong gusts with largely elevated storms tonight. Carolinas/southern VA this afternoon/evening A convectively augmented mid-level disturbance over the southern Appalachians will move into the Piedmont by this afternoon. A moist airmass sampled by area 12 UTC raobs (PW near 2 inches) will heat/destabilize to the south of a patch of clouds more prevalent over western NC. By early to mid afternoon, steepened 0-2 km lapse rates and a belt of slightly stronger westerly 3-6 km flow (30 kt) may act to loosely organize cold pools of developing thunderstorm clusters. Isolated to scattered wind damage (50-60 mph gusts) will be the primary hazard with the more intense water-loaded thunderstorm cores. West TX late this afternoon/evening Strong surface heating and deep mixing along a sharpening dryline will allow high-based thunderstorm development from late afternoon through late evening. Flow aloft will be weak, but inverted-V profiles will favor isolated severe outflow gusts of 60-75 mph.
