Area Forecast Discussion National Weather Service Goodland KS 531 PM MDT Mon Jul 8 2019 .UPDATE... Issued at 337 PM MDT Mon Jul 8 2019 Storms are moving into northeastern Colorado and northwestern Kansas. Strong to severe storms are possible this afternoon and into this evening with large hail, damaging winds, and localized heavy rain possible in addition to flash flooding. A Severe Thunderstorm Watch has been issued for the entire Tri- State area until 10 PM MDT/11 PM CDT. && .SHORT TERM...(This evening through Tuesday) Issued at 1245 PM MDT Mon Jul 8 2019 This afternoon, with the push of a shortwave ahead of a trough moving north of us, expecting to see some convection tonight. As of latest SPC mesoanalysis, our CWA has an axis of instability running diagonally from Yuma County, Colorado, to the border of Greeley and Wichita County Kansas. Areas along and in the northeastern-half of this area have the higher chances of severe weather. Threats include large hail, damaging winds, and flash flooding. Areas that received rainfall last night are in higher risk of seeing potential flash flooding. Tomorrow, dryer and warmer conditions are expected to prevail over the Tri-State area, as high pressure moves in over the Tri- State area. Daily highs will climb up into the low to mid 90s. Not expecting any convection after 12z on Tuesday. Tuesday night, we will see lows in the mid 50s to mid 60s. .LONG TERM...(Wednesday through Monday) Issued at 217 PM MDT Mon Jul 8 2019 Wednesday morning, a trough will continue to progress eastward over the Dakotas and northern Nebraska with a weak ridge over the Bighorns in Central Wyoming. High pressure will set up over the Central High Plains through the day Wednesday as the ridge axis shifts slightly east. Temperatures will be in the mid-80s for highs and the upper 50s to mid-60s for lows. Thursday, the high will shift slightly east, centering over Central and eastern Kansas and Oklahoma. Surface flow will become slightly south- southwest during the day. High temperatures will rebound back into the 90s for highs and the low 60s to low 70s for highs. Long term model guidance suggests that the ridge will remain in place over the Tri-State region through the end of the forecast. Return flow around the high will bring some Gulf moisture into the region. A few shortwaves moving through will bring a daily chance for showers and storms, though areal coverage will be spotty at best through Friday. Saturday and Sunday, there is a little better chance at coverage of showers and storms. && .AVIATION...(For the 00Z TAFS through 00Z Tuesday evening) Issued at 530 PM MDT Mon Jul 8 2019 A line of thunderstorms in northeastern Colorado is slowly moving to the east. Conditions will deteriorate to MVFR between 00z and 04Z as the storms move through the area. The terminal may experience gusty thunderstorm winds during this time in addition to reduced visibility due to heavy rain and lowered ceilings. Conditions will return to VFR for the remainder of the night and through the duration of the forecast period. VFR conditions are expected to prevail at MCK terminal throughout the start of the forecast period. Showers and thunderstorms are expected to be in the area through 05Z which could lower conditions to MVFR for a few hours. Conditions will improve to VFR after showers and storms move through the area. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE.
