Area Forecast Discussion National Weather Service Goodland KS 440 PM MDT Sat Jun 10 2023 .SHORT TERM...(This evening through Tuesday) Issued at 236 PM MDT Sat Jun 10 2023 Across the Tri State region this afternoon, skies are a mostly sunny to sunny mix, with most of the current cloud cover from diurnal heating. The latest RAP40 500mb analysis and mid level water vapor imagery are showing an ridge over the central Rockies with activity forming along the eastern side of the ridge. There is a frontal boundary draped along the northern cwa and a surface ridge to the west. Winds are northerly with stronger gusts near the CO border around 15-20 mph. Temperatures are mainly in the 70s with a few spot 80s. For the remainder of the afternoon into this evening, the main wx concerns will again focus on the potential for strong to severe storms. The threats will be hail initially, but the latest CAMs showing convection to initiate around 00z Sunday near the CO border, form into a line and move across the cwa through 06z. This will shift threat to more wind as the evening progresses. Along with the wind/hail threats, the possibility for heavy rainfall is there again, posing a flash flooding threat. Areas south of the Interstate have the most risk for tonight based on the heavy rainfall received last night. The region will continue to see PW values near an inch with dewpts in the 50s overnight. Model soundings show narrow profiles hinting at heavy rainfall potential. WPC continues to have Excessive Rainfall Outlooks impacting portions of the region this weekend, with the entire cwa under a Slight/Marginal risk for the Monday timeframe. Currently no watches in effect for flooding potential as not all storms will produce the heavy rainfall, limiting areal coverage, but Monday may need one as the threat increases as well as how much areal coverage of rain this weekend. The passage of the storms threat tonight will usher in more cloud cover/cooler temps going into Sunday and Monday as a surface ridge builds south. The increased cloud cover will inhibit temps, while dewpts remain high. The focus for storms on Sunday will mainly be over west-southwest areas as winds go from northerly to more east- southeast. This will persist into Monday as well, keeping the low level moisture feeding into the region during this time. The increased/persistent moisture will increase PWATs keeping the heavy rainfall/flooding threat intact. Model guidance on Monday has upper ridge breaking down over the south-central Plains, allow for a shortwave to traverse the northern periphery into the cwa. This will add further instability for storms in the afternoon/evening. The threat persist during the day Tuesday as the aforementioned shortwave lingers over the KS region providing a focus for storms during the afternoon hours. For temps, highs on Sunday will range widely with upper 60s west to upper 70s east are expected. By Monday, cooler even more with 60s along and west of Highway 83, with up to lower 70s east of there. By next Tuesday, mid 60s west up to mid 70s east with warmest areas east of Highway 83. Overnight lows will have ranges in the 50s for most locales. Far west could see an isolated upper 40s, while isolated near 60F possible east of Highway 83. .LONG TERM...(Tuesday night through Saturday) Issued at 1247 PM MDT Sat Jun 10 2023 Another active pattern looks to be in store for the Tri-State area in the long term. The upper level pattern starts off with the subtropical jet providing zonal flow across the southern CONUS and a low pressure system over the Great Lakes. By Thursday, the jet stream slows a bit and begins moving north, pushing a ridge into the region. That ridge may be short lived as another low pressure system over the Pacific Northwest moves east into the Northern Plains. It's around this time, Thursday, that model guidance begins to vary wildly. There will be chances of thunderstorms every night with the lowest chance of precipitation being Wednesday afternoon. With PWATs remaining around the 1 inch mark, training or slow moving storms could create flooding issues. Shear is back on the menu, at least more than what we have been receiving the past week. This could lead to more organized storm systems that last longer. Temperatures will be a little cooler than normal on Wednesday, and possibly Thursday, depending on how quickly the ridge moves into the area. The jet is expected to act as a barrier and keep warmer/normal temperatures to our south. As the ridge moves over the Tri-State area, temperatures closer to normal, in the 80s, are expected to take over for the remainder of the long term. && .AVIATION...(For the 00Z TAFS through 00Z Sunday evening) Issued at 429 PM MDT Sat Jun 10 2023 Storms are forecasted to impact each terminal this evening, the potential does exist for a severe storm or two with strong winds the primary hazard and torrential rainfall. Storms look to impact KMCK around the start of the period moving in from the NNW and KGLD from an hour or two later from a different cluster of storms advancing east from Colorado. A tempo has been included for each terminal for this potential. Guidance has been showing low stratus developing around sunrise at each terminal as the storms move out of the area. IFR conditions are possible but was not confidentin the timing of the IFR conditions to include at this time so opted to go with high end MVFR for now. The stratus should continue for the most of the day before becoming VFR again by mid to late afternoon. Fog is not currently expected at this time, but will need to be monitored in case winds to weaken a bit more around sunrise. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE.
