It looks like more thunderstorms are on the way, and some of them may be severe with large hail, damaging winds, and heavy rainfall.
The frontal system that seems to have become a permanent fixture on the weather map is still situated to our south and west, though it is beginning to lift north and east. This front is what will cause showers and storms as it tries to move through Greater Nebraska overnight. The best chance for storms is until about midnight, though we could still see some activity through the overnight. It will be warm and humid with lows around 70 under mostly cloudy skies.
Thursday’s forecast is a bit tough because it will depend on exactly where the front establishes itself. If it pushes completely to our north, and ends up over South Dakota, it could become very hot with high well into the 90’s, and it could even approach 100 over extreme southwestern areas. However, if the front stalls over central Nebraska, it will be hot but not quite as hot, especially over southwestern areas. Because of the uncertainty, I am forecasting low to middle 90’s with partly to mostly cloudy skies, with the risk of more late day storms. However, highs could be hotter if the front pushes well north.
Friday could also be quite hot depending on the position of the front, but regardless of where it is Friday morning, it will begin to come southward and cross the regions late in the day. Highs should be in the lower to middle 90’s, and there is a continued risk of late day storms.
The active weather will continue for the foreseeable future until we can get a strong ridge of high pressure into the central Plains. There are signs that this could happen around the middle of next week, but until then expect more of the same.
