FXUS63 KLBF 240515 AFDLBF Area Forecast Discussion National Weather Service North Platte NE 1215 AM CDT Wed Apr 24 2024 .KEY MESSAGES... * A dry forecast is expected through Wednesday afternoon with warming temperatures into the 70s. * The next significant rain and thunderstorm potential arrives on Wednesday night lasting through the weekend. * A slight risk of severe weather is possible on Thursday night and into Friday with large hail, severe winds, and heavy rainfall the primary threats. * Rain and embedded thunderstorms continue through the weekend, however, the potential for severe storms is low. && .SHORT TERM /THROUGH THURSDAY/... Issued at 338 PM CDT Tue Apr 23 2024 A quiet forecast is in store for north central Nebraska through the majority of the short term. Outside of some low end slight chance thunderstorm/rain shower PoPs (15 to 20 percent) across portions of south central Nebraska due to a weak shortwave moving through Wednesday morning, conditions remain dry and mild. As the pressure gradient tightens during the afternoon, southerly winds will increase as well. Expect surface wind gusts up to 25 to 30 mph as a weak trough pushes across the region. Increasing clouds throughout the day on Wednesday will keep temperatures in the mid 60s to low 70s. Overnight lows will remain chilly tonight dropping into the upper 30s to low 40s, but with increased moisture and clouds by Wednesday night, lows increase into the mid to upper 40s. && .LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... Issued at 338 PM CDT Tue Apr 23 2024 Active weather will then arrive on Wednesday night bringing significant rain chances to the region through Sunday as well as potential severe storms on Thursday night and into Friday. The developing low will push into the High Plains on Thursday and will continue to deepen across Nebraska and Kansas on Thursday into Thursday evening. Confidence continues to increase in the potential for severe storms mainly late Thursday evening and into Friday morning. Instability remains fairly weak across much of north central Nebraska until after 6pm CT. During the evening, a small nose of higher instability pushes into southwest Nebraska providing enough support for some isolated severe storms. This ribbon of higher instability will push north and east through Friday morning with the severe potential moving into the Sandhills by 12Z Friday. SPC has increased the risk of severe storms from marginal to slight across our extreme southeast forecast area (Frontier and Hayes counties) which seems to support the latest guidance. At this time, large hail up to 1 inch and strong winds up to 60 mph will be the primary hazards. However, with the small area of convective support, any storms will likely move quickly out of the area with an area of more stratiform rain behind the initial line of severe storms. Still, a few embedded thunderstorms are possible into Friday as the environment continues to get worked through before the system becomes more of a widespread heavy rain event. Increasing rainfall totals also continue to gain confidence with amounts increasing into the 1 inch or higher category through only Friday. Additional rainfall is expected Friday night through Sunday with the only break in the rainfall being a small window on Saturday morning across southwest into south central Nebraska. Thunderstorms will be less likely through the weekend as colder air filters in behind the developing low and heavy rainfall becomes the main threat. While flooding concerns are not expected at this time, nearly 4 days of rainfall, sometimes heavy rainfall, may result in some flooding across low-lying areas or in area fields. Be prepared for some rises in small streams and area roadways as the ground may struggle to keep up with the rainfall at times. Weak upper level ridging across the central US on Monday will bring an end to the heavy rainfall and dry weather into the first part of next week. After falling into the upper 40s to mid 50s over the weekend, gradual clearing of skies will allow temperatures to rise back into the 60s on Monday and into the mid to upper 70s on Tuesday. && .AVIATION /06Z TAFS THROUGH 06Z THURSDAY/... Issued at 1213 AM CDT Wed Apr 24 2024 VFR conditions prevail across western and north central Nebraska with SCT to BKN mid to high clouds through the period. Winds remain light and variable overnight, strengthening out of the southeast this afternoon with widespread gusts of 20 to 30 kts expected. && .LBF WATCHES/WARNINGS/ADVISORIES... None. && $$ SHORT TERM...Kulik LONG TERM...Kulik AVIATION...Viken
