Area forecast discussion, Aug 6, 12:43 AM CDT, 1 hour 57 minutes before
AREA FORECAST DISCUSSION National Weather Service Hastings NE 1243 AM CDT Thu Aug 6 2020 .SHORT TERM...(This evening through Thursday) Issued at 328 PM CDT Wed Aug 5 2020 Skies are mostly clear across the area this afternoon. There are only a few clouds moving through. South winds have helped temperatures to warm into the upper 70s to lower 80s. Expect little change in the weather for the rest of the afternoon and into the evening. It will be later this evening when thunderstorms on the high plains spread an anvil into the area. Expect the thunderstorms on the high plains to move east and could get into the western part of the forecast area closer to 10pm. What happens after it moves into the area is somewhat of a question. Most of the models have it die shortly after entering the forecast area. Yet, there are some that take it across the area. Have kept closer to the majority of the models, but have kept a little buffer of low PoPs, a little further north than what they should be and longer along the southern part of the area. Expect that the southwest will be the main area that could see a couple of hours of thunderstorms this evening. By Thursday morning the upper level wave is out of the area and expect that clouds will diminish during the morning. An upper level ridge builds to the west and temperatures will be a little warmer on Thursday. There is an upper level wave that moves through the area Thursday night. It is fairly weak, but there is a chance for a few thunderstorms overnight. .LONG TERM...(Thursday night through Wednesday) Issued at 328 PM CDT Wed Aug 5 2020 There is an upper level wave that moves through the area Thursday night. It is fairly weak, but there is a chance for a few thunderstorms overnight. Friday through Sunday an upper level ridge builds into the area and temperatures warm up. There are a couple of waves that move through Saturday night and Sunday night with some small chances for thunderstorms, but the period will be mainly dry and warmer with highs in the 90s for most of the area. The period Monday through Wednesday will be nearly zonal flow with a few waves that move through. Timing the waves is always a challenge and expect there will be on and off, mainly small chances for thunderstorms. Temperatures will be a little cooler with highs only in the 80s. && .AVIATION...(For the 06Z KGRI/KEAR TAFS through 06Z Friday) Issued at 1242 AM CDT Thu Aug 6 2020 Scattered thunderstorms are present west of the terminals...did include a Tempo Group at KEAR for prevailing storms, but since high-res guidance continues to limit the eastward extent...have not included the same at KGRI...so will be watching and amend as necessary. Winds are southerly and some low clouds may be present towards the morning with patchy fog. Southerly winds will be breezy...gusting to 20-25kts during the afternoon. && .GID WATCHES/WARNINGS/ADVISORIES... NE...NONE. KS...NONE. && SHORT TERM...JCB LONG TERM...JCB AVIATION...Billings Wright
