Scattered t’storms redevelop Wednesday; severe threat increases into evening

We’ve made it to the month of May this Wednesday… and the many rounds of April showers lately you can surely bet have helped the May flowers. Based on climate normals for the month, we’ll see our average highs rise toward the lower 80s by the end. Overnight lows also get a lot milder.

This May 1st, we’ll be very close to the average high in the upper 60s. Partly sunny conditions with increasing rain and storm chances will help limit our heating during the day compared to the lower 80s of yesterday.

Rain chances increase into the afternoon with some scattered activity moving in from the south before more widespread thunderstorms happen tonight into Thursday.

Showers and thunderstorms are expected to redevelop toward the late morning hours into the afternoon, with weaker storms that may at times become marginally severe with hail as the main concern. It’ll be later tonight into early Thursday that the severe threat is the highest in the near future.

The Storm Prediction Center has southern Nebraska in a Slight (Level 2 of 5) risk for tonight’s storms. Since these storms are expected to be more elevated in nature (higher cloud bases), the tornado threat is low. Primary threats will be hail and damaging wind.

As a warm front lifts north through our area, stronger storms are expected after about 7-8 p.m. tonight in southeast Nebraska. Those storms will lift and weaken through the night, before some flash flooding may occur with the heavy rain expected overnight into Thursday morning.

After this, the severe threat drops for the rest of the week – there’s a Marginal risk for southwest Nebraska by Friday night to keep an eye on.
