Transitioning to cooler conditions
Updated Video 10 pm Weathercast
HASTINGS, Neb. (KSNB) - After an afternoon that saw Grand Island tie a 1934 record of 96 degrees, we will make a transition to much cooler weather as a cold front moves out of northwest Nebraska and sweeps across the state this evening. Cooler temperatures, gusty northwwest winds and the chance for some showers and thunderstorms will be the end result. Storms will be limited for the Tri-Cities area due to warmer air aloft and modest moisture, with the better dynamics for storms positioned north and east of the area. Storms are forecast to pop just around and to the north of Grand Island by mid evening and push east into an area more condusive for better development.
There is a marginal to slight risk area from near Grand Island, east to the Missouri River where storms could strenthen to severe levels capable of producing damaging winds and hail.
In the wake of the front, Friday’s weather will be as much a 20 to 30 degrees cooler with highs only expected in the 40s and 50s far west, to the 50s and 60s central, and 70s southeast.
A reinforcing shot of cooler air will push into the area Friday night into Saturday, when we could see some showers to open the weekend. Highs on Saturday will only warm into the lower 50s, which could threaten records for the ‘coolest afternoon highs’ for May 21st. By Sunday morning temperatures could drop into the 30s over a broad area, promoting a frost threat.
