The drought status for these counties remained largely unchanged, except for the drought worsening to D3 for the far western part of Yuma County. Heavy rainfall events occurred over the eastern parts of these counties, which lessened the drought over the eastern half.

Area Forecast Discussion National Weather Service Goodland KS 1146 PM MDT Tue Jun 30 2020 .SHORT TERM...(This evening through Wednesday) Issued at 241 PM MDT Tue Jun 30 2020 As of 3 pm CDT...2 pm MDT...skies across the Tri-State Region are clear. Temperatures are quite nice, relatively, compared to yesterday's heat. Current readings are in the 80s across east Colorado, ranging to the mid 90s towards Hill City, Kansas. Winds are generally north at 10 to 20 mph...gusting to 30 mph at times. At the surface, a cold front extends roughly from just east of McCook, NE to just west of Hill City. Aloft, a shortwave trough is moving across Colorado. Latest radar and satellite trends show a few showers developing in Colorado in association with this disturbance. For the rest of today, a few showers/storms could move across locations north of I-70. In addition, a storm or two could form in Red Willow, Norton, and Graham Counties along the cold front. Anything that is able to fire along the front in the previously mentioned counties could be severe as there is a large amount of instability (SBCape of 3000 J/kg, lapse rates of around 8 C/km) and shear (effective bulk shear of 60 kts or so, 0-3 km SRH of 100-200 m2/s2). The main threats would be large hail and damaging winds. Behind the front, instability is quite lacking with MUCAPE around to less than 500 J/kg so am not anticipating much in the way of severe weather behind the cold front. For the rest of the evening, the cold front will move east, exiting the area and taking any precipitation with it. For tomorrow, surface high pressure will move across the region. As this happens, subsidence aloft will prevent any convection developing, so expect a precipitation free day. Winds will be generally light although southeast winds will return. Winds may pick up across eastern Colorado during the afternoon hours. Temperatures will be in the 90s and with low relative humidity readings, there will be elevated fire weather conditions along and east of HWY 27. Otherwise, quiet weather should be expected. .LONG TERM...(Wednesday night through Tuesday) Issued at 220 PM MDT Tue Jun 30 2020 Somewhat uncertain forecast for the holiday weekend as large H5 ridge begins to build to the north and becomes centered over the Goodland CWA. While normally this would lead to a a period of hot and dry conditions, but unlike some of the past ridges, looks like airmass over the area will be somewhat humid. With possibility of more clouds, have questions on how warm things will get actually get. Kept forecast on the warmer side of data distribution, but for the reasons mentioned earlier am hesitant to push temps to the extreme end of heat. Looks like highs will continue in the lower to mid 90s throughout the period, with another round of 100 degree weather possible should moisture profile not be as high as expected. Given the weak flow associated with the building ridge it is hard to really focus on the individual disturbances that may help set of thunderstorms. Instead, think we will see pattern favorable for diurnally driven storms in the late afternoon and evening with close to climatologically normal (20-30%). && .AVIATION...(For the 06Z TAFS through 06Z Wednesday night) Issued at 1125 PM MDT Tue Jun 30 2020 VFR conditions are anticipates at MCK and GLD through the 06Z TAF period. Skies will be mostly clear with light north winds overnight turning southeast by late afternoon/early evening on Wednesday. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE.
