Area forecast discussion, Jun 30, 3:29 PM CDT, 1 hour 28 minutes before
Area Forecast Discussion National Weather Service Hastings NE 329 PM CDT Sat Jun 30 2018 .SHORT TERM...(This evening through Sunday) Issued at 328 PM CDT Sat Jun 30 2018 A few thunderstorms have developed along a front that is nearly stationary across far southern Nebraska this afternoon. Otherwise, there are mostly cloudy skies for much of the area. Temperatures to the south of the front are in the upper 80s to lower 90s and to the north are mostly in the upper 70s and 80s. The initial period will be the most interesting. The front should be the focus of thunderstorms during the late afternoon hours. This area has dew points around 70 degrees. These will be mainly wind and hail as they affect the area this afternoon into the evening. Later, mainly during the evening hours, an upper level wave will move into the area and bring a line of thunderstorms into the area. These should develop on the high plains and move into the area during the evening. These storms will have mainly wind as the storms move through. All of the storms should be through the forecast area by morning. A surface high moves into the area behind the thunderstorms and clears things out for Sunday. The skies will become sunny, but temperatures will be a little cooler with highs only in the 80s. This will be cooler than much of the last week has been. .LONG TERM...(Sunday night through Saturday) Issued at 328 PM CDT Sat Jun 30 2018 Sunday night through Monday should be a dry period, with temperatures warming up a little. The surface high moves to the east Sunday night and by Monday the winds turn to the south and will help temperatures warm a little. The south winds will continue to bring in warmer temperatures through Tuesday. There is a weak upper level wave that moves through the area Monday night and there could be a few thunderstorms. For the period Tuesday night through Saturday there will be an upper level ridge across the central and eastern part of the CONUS. There are a few mainly weak upper level waves that move around the ridge. There could be a few thunderstorms, but they should be more on and off and not very widespread. Temperatures will be fairly warm with highs in the upper 80s and 90s across the area. && .AVIATION...(For the 18Z KGRI/KEAR TAFS through 18Z Sunday) Issued at 1224 PM CDT Sat Jun 30 2018 The MVFR ceilings should be relatively short lived and there could be a little clearing during the afternoon, just enough to get more thunderstorm development for later this afternoon and into the evening. The thunderstorms should move out of the area late tonight and clearing is expected behind the thunderstorms as a surface high builds into the area. && .GID WATCHES/WARNINGS/ADVISORIES... NE...None.
