Area Forecast Discussion National Weather Service Goodland KS 155 PM MDT Sun Apr 21 2019 .SHORT TERM...(This evening through Monday) Issued at 145 PM MDT Sun Apr 21 2019 Scattered to numerous thunderstorms will move out of northeast Colorado and across northwest Kansas/southwest Nebraska this evening as shortwave trough ejects across the area, exiting to the north by around 07z. Severe threat will be limited to about 04z, then wane as boundary layer cools. Primary hazard will be wind gusts of up to 60 mph with favorable DCAPE environment/relatively high bases, followed by a marginal threat of hail up to quarter sized, and finally a low end risk for locally heavy rainfall. Clouds will persist through the night with breezy north winds. Lows will range from the upper 30s in Colorado to the lower 50s in north central Kansas. Clouds will persist into Monday with perhaps some partial clearing late in northern areas. As a result, temperatures will be much cooler, with highs in the upper 50s to lower 60s. North winds will be gusty and strongest in the morning, then slowly diminish in the afternoon. .LONG TERM...(Tuesday through Sunday) Issued at 139 PM MDT Sun Apr 21 2019 While near term models show a decent amount of disagreement with how southern plains H5 trough evolves, consensus still appears that system will track well to the south of the area with only slim chances of light precipitation glancing the southern CWA. After system departs, medium range models in reasonable agreement that ridging will build over the area through the weekend. Differences emerge with the amplification and strength of the ridge, with the GFS being a bit more amplified than other available guidance. Regardless of preferred solution, seems like weather will be fairly quiet from Tuesday through Thursday as temperatures slowly warm, but surface flow does not look really favorable for any meaningful moisture return until Thursday Night and Friday as sfc high shifts east and strong southerly flow develops again. Should we get enough moisture/instability development shear profile with fast zonal flow would support some organized/severe storms, but details at this point remain very unclear. Main forecast changes to available guidance were to nudge temperatures to warmer end of distribution/ensemble data, although potential for mountain cirrus limiting insolation a bit concerning. && .AVIATION...(For the 18Z TAFS through 18Z Monday afternoon) Issued at 1121 AM MDT Sun Apr 21 2019 Main aviation concern will be thunderstorm chances this afternoon and tonight at both KGLD and KMCK. Expecting a line of storms to develop south of KGLD by mid afternoon which will progress northward during the late afternoon and evening hours. Gusty winds and small hail may accompany the storms at KGLD, but with later arrival time at KMCK do not expect storms to be as strong. Thunderstorm threat will end by 04z at KGLD and 07z at KMCK. During the overnight, models show MVFR ceilings moving into the area from the north and persisting through Monday morning. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE.
