CHARLOTTE, N.C. -- The Charlotte area is back under a severe weather threat this evening. The entire region will see a very high risk for damaging winds from 60-80mph. There will also be a smaller threat of isolated tornadoes or hail.

Temperatures are in the very warm low 90s this afternoon. A strong cold front will move into our area late in the day.

Our big problems will come along the front itself where a squall line will pose a widespread damaging wind threat. The main line of storms will carry a very high threat for 60-80mph winds. We will also watch for bow echoes within the main line of storms.

A bowing line segment shows up as an arched or bowed-out line of storms within the larger or main line of storms. Bow echoes are associated with an axis of enhanced wind speed that can do a tremendous amount of damage at the surface. Tornadoes can also occur in the parent line of storms or in bowing line segments, but they are usually shorter-lived and weaker than those we see in individual supercell thunderstorms.

If any individual storms can develop out ahead of the cold front, they will be watched for possible rotation, isolated tornadoes or downburst winds.

 

Downburst winds are powerful winds that descend vertically from a thunderstorm then spread out horizontally once they hit the ground. These winds can easily cause damage on the scale of EF0 to EF1 tornadoes with speeds from 65 to 110 mph.

As we saw in Monday’s storm winds, trees are easily snapped or toppled causing damage to homes, cars and power lines. These storms may also pose a large hail threat.

Storms will march east as we move into the overnight. Behind the front, we will see clearing skies.

Friday will be sunny and less humid, with highs in the low 80s. The upcoming weekend looks great with plenty of sunshine. Morning lows will be back in the lower to mid-60s and afternoon highs will stay in the 80s.
