Tornado Watch issued for southeast Nebraska

Date: 2021-12-15 19:53:56

Wednesday looks like it’s shaping up to be a very active weather day across the state of Nebraska. Let’s discuss what is possible one by one.

SEVERE STORMS

We’re watching the potential for severe storms as well. A Tornado Watch is in effect until 8PM Wednesday for all of southeast Nebraska.

Stormcast shows a line of thunderstorms developing in eastern Nebraska. This would likely arrive in Lincoln in the ballpark of 2-6PM.

Stormcast Wednesday Afternoon

Know that we may see a few embedded tornadoes within this line of thunderstorms. That said, the main threat with these is damaging straight-line winds. The wind speeds aloft are very strong, and a thunderstorm would be a good way to mix those winds down to the surface. Understand that if a storm develops, there is a good chance of it becoming severe.

Severe Weather Threat Assessment

These storms will be very fast-movers, so the lead times may be shorter than usual.

HIGH WINDS

A High Wind Warning is in effect until 9PM CST for all of Nebraska. This type of warning is not issued very often, which highlights how windy Wednesday will be.

The potential is for sustained winds in the ballpark of 30-40mph with wind gusts in excess of 60mph. In some areas, we may see wind gusts exceeding 75mph on Wednesday.

Stormcast Winds Wednesday Afternoon

If you haven’t already, secure your loose outdoor items or bring them inside so they don’t blow away! Please be very careful while traveling on Wednesday. Travel will be more difficult for high-profile vehicles. Winds this strong can overturn semi-trucks, so be extra cautious driving around those.

These winds are likely all afternoon and evening and will occur outside of thunderstorms.

FIRE WEATHER

Wind speeds will be elevated throughout much of the afternoon and evening. As the day wears on, the air will start to dry out. The combination of dry air with gusty winds will make for conditions conducive to rapid fire spread.

A Red Flag Warning is in effect until 9PM Wednesday for southeast Nebraska.

Red Flag Warning

Per the National Weather Service: “Any fires that ignite will spread rapidly and exhibit extreme behavior. Outdoor burning is not recommended.” Outdoor burning is not a good idea on Wednesday.

RECORD WARMTH

As of 12PM Wednesday, Lincoln has already shattered the record of 64° set back in 2002. Highs should top out in the low-70s Wednesday afternoon – well above our average high of 39°.

Temperatures quickly plummet Wednesday night as low temperatures bottom out near 28° on Thursday morning in Lincoln.

SNOW?

As this storm system pushes off to the east, colder air begins to arrive across the state. This could bring some accumulating snow for northern Nebraska. Some computer model guidance suggests the potential for a brief flurry out towards Kearney on Wednesday evening. Accumulations are not likely there. No snow is expected in Lincoln.

Make sure to have a way to receive weather alerts this afternoon and evening. We’ll continue to provide updates on-air and online as needed. Stay safe!
