Area forecast discussion, Aug 7, 1:23 AM CDT, 2 hours 49 minutes before
Area Forecast Discussion National Weather Service Hastings NE 123 AM CDT Wed Aug 7 2019 .SHORT TERM...(This evening through Wednesday) Issued at 326 PM CDT Tue Aug 6 2019 Satellite and observations show mostly sunny skies across the area this afternoon. A weak surface high will continue to move east this evening. An upper level wave will move into the area tonight. Models still have a few differences in the timing of thunderstorms for tonight. The GFS is earlier, but the NAM and HRRR are both later with the thunderstorms. Have slowed down the PoPs just a little bit. Expect most of the thunderstorms toward morning. With the thunderstorms late tonight, they will likely continue into Wednesday morning across the eastern part of the area. By afternoon, the wave is still lingering and there could be a few, mainly spotty, showers and thunderstorms with the afternoon heating. .LONG TERM...(Wednesday night through Tuesday) Issued at 326 PM CDT Tue Aug 6 2019 An upper level ridge just to the west of the forecast area will leave northwest flow across the area for Wednesday night through Sunday. There are expected to be some mainly weak upper level waves that move through the area. These lead to on and off, mainly small, chances for thunderstorms. With the waves being weaker in nature, the models are challenged to keep the timing and location of the waves consistent. This also leads to having smaller, more generalized PoPs across the area. Temperatures should be mostly in the 80s to lower 90s, just a little below the normal highs for this time of year. Sunday and Monday, the ridge pushes just a little east, but there are still some weak waves that move across the ridge. This will keep the small chances for thunderstorms across the area and some clouds will keep temperatures in the 80s. By Tuesday, the ridge builds to the west again. There is another wave that moves through, but it is pretty weak. Temperatures will be just a little cooler. && .AVIATION...(For the 06Z KGRI/KEAR TAFS through 06Z Thursday) Issued at 117 AM CDT Wed Aug 7 2019 Thunderstorms will impact KGRI between 0730Z and 1000Z, but should remain just to the northeast of KEAR. The wind could be gusty and variable in and around thunderstorms. However, after the storms pass off to the southeast prior to sunrise the wind will again become light and variable with VFR conditions. The wind will remain light through the day and become more easterly with time. Can not rule out thunderstorm redevelopment again this evening, but there is a lot of uncertainty regarding where storms could reform this evening anywhere from southern Nebraska to central Kansas. && .GID WATCHES/WARNINGS/ADVISORIES... NE...None. KS...None. && SHORT TERM...JCB LONG TERM...JCB AVIATION...Wesely
