Area forecast discussion, Aug 4, 5:47 PM MDT, 0 minutes before
Area Forecast Discussion National Weather Service North Platte NE 647 PM CDT Sun Aug 4 2019 .SHORT TERM...(This evening through Monday night) Issued at 352 PM CDT Sun Aug 4 2019 The main concern this forecast period is thunderstorm development this afternoon and evening. Thunderstorms will continue to develop across northwest Nebraska this afternoon. There is some inconsistencies with the models in how far eastward the thunderstorms will sustain themselves. Leaned more with HRRR and HREF where storms will form into a cluster across northern Nebraska and drop southeastward but should enter a less favorable environment and will begin to diminish before reaching portions of southwest and central Nebraska. Storms that occur late this afternoon and evening have the potential to become strong to severe, with the main hazards being strong winds, large hail and heavy rain potential. The best chance for severe thunderstorms will be across northwestern Nebraska, mainly along and west of a line from Kilgore to Ellsworth. A cold front will push through the area on Monday. There is a chance of thunderstorms Monday afternoon and evening in association with the cold front. At this time the severe threat looks to be marginal as storms may develop behind the cold front in a less favorable environment for severe storms but with the amount of moister in the area could have the potential for heavy rainfall. .LONG TERM...(Tuesday through Sunday) Issued at 352 PM CDT Sun Aug 4 2019 Surface high pressure will sit over the Central Plains Tuesday into Wednesday before a frontal boundary moves through the area Wednesday evening. Highs will remain seasonal in the 80s, with slight chances of thunderstorms on Tuesday afternoon and evening. A better chance of widespread thunderstorms will be Wednesday afternoon in association with the cold front. Cooler temperatures on Thursday and Friday with highs only in the upper 70s to low 80s. There will be a chance of thunderstorms Thursday through Sunday. && .AVIATION...(For the 00Z TAFS through 00Z Monday evening) Issued at 643 PM CDT Sun Aug 4 2019 Scattered thunderstorms across the central Sandhills to near VTN will continue to push south and east this evening. Expect quickly improving conditions at VTN with return to VFR by 05/01z. Rain and storms will move into TIF/ANW/ONL areas by 05/02-04z timeframe and be capable of brief strong winds up to 35 knots and visibility less than 1 mile with RA+. Confidence in impacts at LBF are low at the moment so have limited wording to VCSH for now with possible amendments to come later. && .LBF WATCHES/WARNINGS/ADVISORIES... None. && SHORT TERM...Gomez LONG TERM...Gomez AVIATION...Jurgensen
