Thursday Forecast: Staying warm and humid with more thunderstorms expected into Thursday evening
LINCOLN, Neb. (KOLN) - Another round of strong to severe thunderstorms headlines your forecast as we head into Thursday afternoon and Thursday night. The midday update from the SPC keeps south central and southeastern Nebraska and northern Kansas under a slight and enhanced risk for severe weather. Large hail, damaging winds, isolated tornadoes and locally heavy rain will all be possible into Thursday evening.
Partly to mostly cloudy skies are expected as we head into Thursday afternoon and most of us should remain dry, though there could be a few hit and miss showers and isolated t’storms across the state. Into the mid and late afternoon hours, a remnant outflow boundary from this morning’s convection is expected to lift north into parts of southern Nebraska and northern Kansas. At the same time, a low pressure system across Kansas and the low-level jet will strengthen across the area, which should lead to scattered supercells developing near that lifting outflow boundary. How far north that boundary reaches will be a big determining factor in where the severe weather sets up this afternoon and evening. If that boundary doesn’t reach as far north ,severe storms would likely stay south of our area, it if reaches a little farther north than expected, we could see more widespread severe weather across the area. Regardless of where the boundary sets up, storms are forecast to develop by this afternoon and initially could pose a threat for some very large hail and some isolated tornadoes. Storms are then progged to develop into another bowing complex that will move to the east and southeast towards eastern Kansas and western Missouri.
More warm and humid weather is on tap by Thursday afternoon with temperatures reaching back into the mid and upper 80s for most of the area with a few locations in far southern Nebraska potentially reaching into the lower 90s. After seeing much of the moisture used by early morning thunderstorms across the area, the atmosphere is expected to recharge by this afternoon with dew points jumping back to the upper 60s and lower 70s with southeast winds at 5 to 15 MPH.
The extended forecast will keep periods of stormy weather in the forecast over the coming days with temperatures falling into the lower 80s on Friday and into the upper 70s by Saturday as we start the weekend. From there, temperatures should settle into the lower and middle 80s by Sunday and into early next week as models indicate an upper level trough settling into the area. This will keep rain chances in the forecast for much of next week with near normal temperatures.
