783 FXUS63 KLBF 181940 AFDLBF Area Forecast Discussion National Weather Service North Platte NE 240 PM CDT Sun Apr 18 2021 .SHORT TERM...(This evening through Monday night) Issued at 236 PM CDT Sun Apr 18 2021 Westerly downslope flow has boosted temperatures into the 60s this afternoon across western and north central Nebraska. This is ahead of a strong upstream cold front and shortwave that is currently moving into the northern Rockies and Plains. The cold front will quickly move southward this evening and reach the NE/SD border about 8pm or so then continue to move south through the area overnight. A band of strong mid-level FGEN and lift will sag into the area behind the front and be located across northern Nebraska by Monday morning. Sounding profiles indicate strong warm air advection in the 750-650 mb layer through the morning hours then fades during the afternoon as the band drops southward. Should be some decent snowfall across portions of northwest into north central Nebraska late tonight into Monday morning, with the snow or snow/rain mix weakening somewhat as it shifts southward during the early to mid afternoon. Late in the afternoon into Monday evening hours, a jet streak will drop through the central Rockies then head east southeast into Kansas and Oklahoma. Snow band should re-intensify within left exit region of the streak across the southern Nebraska Panhandle, northeast Colorado and southwest Nebraska during this time. After midnight the band quickly shifts east/southeast away from the area with snow ending. As far as accumulations, 1-3" still looks good across northwest Nebraska late tonight into Monday morning where a Winter Weather Advisory is already in effect. Then Monday evening a quick 1-3" is possible across portions of southwest Nebraska as the snowband re-intensifies. Will hold off on any headlines for this area as it will be 12-16 hours later and it is possible that the location could change somewhat with a shift farther south, etc. Otherwise cold and windy Monday behind the front with lows Monday night dropping to between 18-25 as skies clear and winds decrease. .LONG TERM...(Tuesday through Sunday) Issued at 236 PM CDT Sun Apr 18 2021 Another weak wave drops southeast across the area Tuesday with perhaps a bit of light precipitation and increased cloud cover once again. In addition another cold front surge will keep northwest winds up. Flow aloft will become more zonal toward the end of the week with a warming trend. Highs by Saturday should be in the 60s with 70s Sunday. && .AVIATION...(For the 18Z TAFS through 18Z Monday afternoon) Issued at 219 PM CDT Sun Apr 18 2021 A cold front will usher in MVFR and local IFR ceilings tonight into Monday.
