Area Forecast Discussion National Weather Service Goodland KS 238 PM MDT Sat Jul 22 2017 .SHORT TERM...(This evening through Sunday) Issued at 236 PM MDT Sat Jul 22 2017 Latest upper air analysis shows a trough breaking down the ridge over the Plains. Ahead of this trough showers and thunderstorms were developing. At the surface an outflow boundary/cold front was moving southeast. A second boundary was present running from Johnson City northeast to Oakley and Hill City then turning east toward Stockton. Along the east extent of the cold front cumulus clouds were developing. So far the storm activity has been remaining behind the outflow boundary in the more stable environment. Due to the cold front advancing southeast faster than expected, am beginning to wonder if any severe weather will occur for the southeast part of the forecast area today. Based on the current speed of the boundary, the cold front will be on the southeast border of the forecast area in roughly 2 hours. While severe weather cannot be ruled out yet, the window of opportunity is quickly shrinking. In addition, by the time peak lift from the upper level short wave trough will occur, the front will be well south of the forecast area. If severe weather does occur it will be south of a Hoxie to Hill City line and east of a Russell Springs to Hoxie line. Should severe weather occur, hail up to ping-pong ball size is possible with the strongest storms, along with damaging wind gusts. Due to the almost stationary nature of the storms, heavy rainfall is likely. This may cause flash flooding in low lying areas, but do not have enough confidence at this time to issue a watch. There maybe some lingering storms over the southeast half of the forecast area overnight ahead of the upper level short wave trough that will be moving slowly south. Sunday morning the upper level short wave trough will move south of the forecast area before mid morning. Once it does the weather should be dry due to subsidence/very weak lift moving overhead as the ridge, that retrograded west during the overnight hours, pushes back east onto the High Plains. Due to the cooler air mass in place highs will be cooler than today. .LONG TERM...(Sunday night through Saturday) Issued at 236 PM MDT Sat Jul 22 2017 Sunday night-Tuesday: This period should remain dry as upper level ridging dominates the weather. Temperatures will be above normal with eastern sections of the area once again, seeing highs near the century mark on Monday and Tuesday. Tuesday night-Saturday: Ridge flattens somewhat allowing zonal to NW flow aloft. Series of shortwaves will traverse the area through the period. These, combined with some leeside troughing at the surface will bring chance to likely PoPs through Saturday morning with best rain and storm chances coming Thursday night through Friday night. Some storms may become strong to severe each afternoon and evening. Temperatures now look to be at or below normal for the period. 12Z Euro MOS actually has a high of 79 in Goodland on Thursday. Will be fine tuning the forecast through the weekend to better pinpoint hazards and temps since global models have not been very consistent from run to run the past few days. && .AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon) Issued at 114 PM MDT Sat Jul 22 2017 Updated timing on both TAFs to account for earlier arrival of showers and storms... Previous Discussion: For KGLD and KMCK...VFR conditions expected through the period. Main concern will be thunderstorms this afternoon and whether they will directly affect terminals. Line of storms currently in Dundy and Hitchcock counties are slowly moving to the east towards KMCK. Some computer models have these storms dying out before reaching the terminal, but looking at radar trends, it will be close. Went with VCTS for both terminals for the afternoon. Tempo for KMCK since one of the approaching storms could make it to the terminal before dissipating. Winds overnight become light and slowly turn from NE to W by sunrise. Went with variable just to account for the direction changes. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE. NE...NONE. && SHORT TERM...JTL LONG TERM...SME AVIATION...SME

Large hail up to ping- pong ball size and damaging winds will be the main threats. Due to the nearly stationary storm movement, heavy rainfall will also occur. Flash flooding may occur in low lying areas east of Highway 25 and south of Highway 24. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH SATURDAY...
