KEARNEY — A Slight Risk for severe weather is in place for western Nebraska and parts of central Nebraska during the evening of Tuesday, Sept. 16.
According to the National Weather Service – Hastings, the area can expect dry conditions to persist through most, if not all of the daylight hours.
Thunderstorms are expected to develop over the Sandhills as models are in good agreement as to where initial storms will initiate along and ahead of a cold front.
Isolated to scattered coverage during the late afternoon and early evening is forecast to grow upscale into a larger storm complex by sunset thanks to modest wind shear that will be in place.
The speed and timing of the storm complex will have an impact on the threats for the region. If the complex arrives around 7-10 p.m., there will be higher chances for marginally severe hail, a quarter to half dollar size and severe winds.
If convection is slower to shift east, then mostly sub-severe winds up to 45-55 mph will be expected and locally heavy rainfall amounts of 1-2 inches per hour will be the main concerns, per NWS Hastings.
The greatest concentration and magnitude of the severe risk looks to lie mainly west of Highway 283, with a gradually decreasing risk with time and eastward extent.
Scattered to widespread showers and non-severe thunderstorms are likely to persist well pass midnight and some areas east of Highway 281 might be able to manage at least a few tenths of rain.
The heavier, isolated 2-3 inches of rainfall looks to lie mainly west and northwest of the Tri-Cities earlier in the evening. Rain will generally decrease from west to east by Wednesday morning as subsidence works in behind the initial upper-level disturbance.
Areas that remain under thicker cloud cover could struggle to warm out of the 60s, but most should see the 70s on Wednesday.
