156 FXUS63 KLBF 292045 AFDLBF Area Forecast Discussion National Weather Service North Platte NE 345 PM CDT Wed Mar 29 2017 .SHORT TERM...(This evening through Thursday) Issued at 344 PM CDT Wed Mar 29 2017 The wrap-around rain and drizzle across Ncntl and Swrn Neb should slowly move east tonight. The forecast uses the HRRR models and RAP model. This rain is associated with lower level moisture and support from the upper low across KS. Most of the short range models show fog forming across the Sandhills tonight. The RAP model indicates dry air moving in at the 850-500mb layer and this would promote radiational cooling given the clearing skies and light winds that are expected to develop tonight. Areas east of highway 83 remain in the wrap-around clouds overnight. Clearing is expected from west to east Thursday afternoon across the Ncntl Neb. The forecast uses blended guidance plus bias correction. The wet ground appears to limit lows tonight to a few degrees above the straight guidance numbers. Highs Thursday rise into the upper 40s east to around 60 west where mostly sunny skies are expected. .LONG TERM...(Thursday night through Wednesday) Issued at 344 PM CDT Wed Mar 29 2017 Friday will be a transition day in between systems, as upper level ridging briefly builds over the area ahead of the next system that will dig southeast to near the four corners by Friday evening. By Friday afternoon clouds will be on the increase, with rain likely developing across portions of the Panhandle and southwest Nebraska Friday night. The center of the upper level low pressure system will very slowly meander it's way into northern New Mexico Saturday. Ahead of the system deep southerly flow aloft will draw moisture northward, with rain once again expected through Saturday from the western half of Nebraska, southward through Oklahoma and Texas. Sunday could see a lingering shower or two as the system moves into the plains from New Mexico and weakens. There is yet another system that arrives Tuesday into Wednesday, this too appears quite vigorous with more rain and perhaps some wet snow. All in all beneficial moisture will continue to accumulate the next several days. && .AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon) Issued at 1233 PM CDT Wed Mar 29 2017 Showers will remain in the vicinity of KLBF, KBBW and KONL through late this afternoon, but thereafter ceilings will gradually lift into the evening. Dryness in the mid levels may promote the development of fog at KVTN and other north central Nebraska terminals overnight as winds go light, but fog should be absent across southwest Nebraska. Overall forecast confidence is good due to strong model agreement. && .LBF WATCHES/WARNINGS/ADVISORIES... None. && $$ SHORT TERM...CDC LONG TERM...Taylor AVIATION...Jacobs
