Area forecast discussion, Jul 6, 11:18 PM MDT, 26 minutes before
Area Forecast Discussion...UPDATED National Weather Service North Platte NE 1218 AM CDT Sun Jul 7 2019 .SHORT TERM...(This evening through Sunday night) Issued at 326 PM CDT Sat Jul 6 2019 Atmosphere again in recovery mode this afternoon in the wake of the latest MCS that crossed the area last night. A weak surface low is noted across north central Nebraska, with bands of stratocumulus clouds in areas of weak convergence across the region. An isolated weak thunderstorm could develop in one of those areas of weak convergence, but the better threat of thunderstorms will come later this evening and overnight. HRRR and several other Hi-Res HREF members organize thunderstorms into a small complex across the central and southern Panhandle early this evening. The storms then track east across portions of the southern Sandhills and southwest Nebraska late this evening and overnight. Some strong wind potential with the cluster as well as locally heavy rainfall. Will carry a swath of likely pops where the system is expected to track with 40 or less pops elsewhere. Similar set up on Sunday with southeast moist low-level flow aiding in destabilization across the western High Plains Sunday afternoon and evening. This should once again lead to scattered afternoon thunderstorm development, with the activity possibly moving into western Nebraska Sunday evening. Otherwise southeast winds will increase Sunday as pressure falls across the Western High Plains. Gusts up to 30 mph are possible across portions of the Sandhills and north central Nebraska. The increased wind will aid in better mixing with highs into the mid 80s across western Nebraska. .LONG TERM...(Monday through Saturday) Issued at 326 PM CDT Sat Jul 6 2019 The start of the upcoming week will be unsettled. Upper level ridging will be suppressed well south as an upper level trough moves east across the Central and Northern Plains. This will lead to an uptick in shower and thunderstorm chances Monday and Tuesday. By the middle and latter parts of the week, GEFS and ECMWF build upper level ridging into the four corners region and much of the Central and Southern Plains. This will spread a warm layer aloft across much of the region which will limit rain chances. Above normal temperatures are also expected, with highs climbing into the lower 90s by Friday and Saturday. && .AVIATION...(For the 06Z TAFS through 06Z Sunday night) Issued at 1218 AM CDT Sun Jul 7 2019 Numerous thunderstorms will move through wrn and ncntl Nebraska overnight and exit the region 10z-13z this morning. Scattered thunderstorms are possible this afternoon and this evening, mainly south of highway 20. Otherwise VFR is generally expected across western and north central Nebraska Sunday and Sunday evening. && .LBF WATCHES/WARNINGS/ADVISORIES... None. && SHORT TERM...Taylor LONG TERM...Taylor AVIATION...CDC
