520 FXUS63 KGID 070100 AFDGID Area Forecast Discussion National Weather Service Hastings NE 800 PM CDT Sat Jul 6 2024 .KEY MESSAGES... - A few strong storms will be possible this evening with half inch hail and 50 mph wind gusts, but widespread severe weather threat has ended. - A few strong storms will be possible again across the local area during the daytime hours on Sunday, although severe weather is unlikely. Chances for thunderstorms should rapidly diminish during the early to mid evening hours tomorrow. - Mostly dry conditions expected next week with just a small chance for thunderstorms Wednesday. - Temperatures will start off the week on the cooler side of normal with a gradual climb back into the 90s for the end of next week and into next weekend. && .DISCUSSION... Issued at 734 PM CDT Sat Jul 6 2024 An active afternoon of weather as as upper level disturbance sparked widespread strong to severe thunderstorms across the local area. A line of redevelopment on the backside of these storms is noted along I-80 this evening, but is expected to remain sub-severe and transitory...pushing eastward and out of the local area by late evening. Could see a few strong storms also reach the local area from development across the high plains this evening, but again, severe weather does not appear likely with this activity either. For Sunday...expect yet another upper level disturbance to track across the local area in the longwave trough, sparking additional showers and thunderstorms across the region. While some of the mesoscale models bring a resurgence in activity prior to dawn - possibly associated with the high plains convection this evening, think the main disturbance/forcing will mostly be a daytime event as this next wave is still well to our northwest across Montana this evening. This would be more in line with the NAM and global models which bring this disturbance across the local area during the daytime hours Sunday. Either way, environmental conditions do not appear favorable for widespread severe weather, and outside a few strong storms, severe weather is not anticipated and the local area remains only in an area of general thunder from SPC. Behind this next disturbance, a nice start to the week is anticipated with high temperatures mainly in the lower 80s along with mostly sunny skies. As the upper level ridge then builds across the west coast, temperatures locally will also begin to climb, with a return to above normal temperatures expected by the end of the week. In addition, there will be a small chance for thunderstorms again on Wednesday with a weak disturbance in the resultant northerly flow, but this has trended down in the past 24 hours, and most location will likely remain dry over the course of the week. && .AVIATION /00Z TAFS THROUGH 00Z MONDAY/... Issued at 616 PM CDT Sat Jul 6 2024 For KGRI/KEAR Airports: An area of SHRAs and TSRAs has developed upstream of the terminals the past hour. Expect these storms to impact both TAF sites through around 07/02Z...with improving conditions expected thereafter. Behind this line of storms, only some scattered mid level clouds are anticipated for the remainder of the night, with another disturbance focused mainly south of the terminals expected to bring a possible VCTS along with MVFR CIGS for much of the day beginning around 07/12Z. && .GID WATCHES/WARNINGS/ADVISORIES...
