You may want to have a Plan B as severe weather will likely crash your party tomorrow evening

HASTINGS, Neb. (KSNB) - Most of us will enjoy a quiet evening and overnight tonight. The exception will be northern counties along the South Dakota border where thunderstorms are expected to fire up later this evening into the overnight. There is a lower end chance of some severe weather across far northern spots in the viewing area. Otherwise, quiet for the rest of us with lows tonight in the low to mid 60s.

A cold front will begin diving southeast through Northwest Nebraska late tonight and tomorrow morning. Temperatures will be noticeably cooler behind the front. But it will be a rather toasty out ahead of the front. Most of those places will reach the 90s in the afternoon. There may be some lingering showers and thunderstorms in Northern Nebraska tomorrow morning. As the front proceeds southeast, a few more thunderstorms may fire up through the afternoon. So the timing of the cold front will be important to determining where the better chance of thunderstorms will be. Meanwhile, behind the front, temperatures will be dropping. Highs will be in the 80s and 70s as you go to the northwest with some seeing drops in temperatures once the front comes through. I do expect thunderstorms to really start firing up starting mid afternoon near that front. At this point, the chance of severe storms will increase rapidly. There is an enhanced risk of severe threats tomorrow with the biggest threat being damaging wind gusts between 60 and 80 mph. Hail to quarter in size will be the secondary threat. While not expecting any tornadoes, we can’t rule out a quick spin up along the line of storms. This line will trudge eastward with the cold front through the evening. Later in the night, more showers and thunderstorms could move across the area from west to east with at least a lower end chance of severe storms, but also a potential flooding threat. While the chance will continue through the late night, much of the heavier activity will move out by Wednesday morning. Lows Wednesday morning will be down into the mid 50s to the mid 60s behind the front as it clears out.

On Wednesday, some showers and isolated thunderstorms may linger through noon time, but most will clear out by the afternoon. It’ll be an unseasonably cool day with highs mostly in the low to mid 70s. There will still be some chances for showers and thunderstorms through the end of the week. At least a slight chance will continue this weekend. Temperatures are expected to continue to be on the cooler side for July with highs mostly in the 70s. It may warm up a little more over the weekend, but most will remain a bit below average.
