774 FXUS63 KGLD 252331 AFDGLD Area Forecast Discussion National Weather Service Goodland KS 531 PM MDT Tue Jun 25 2024 .KEY MESSAGES... - Not as hot through the weekend. - A little more promising for widespread rainfall Wednesday night, Thursday night and Friday night. - Severe thunderstorms possible Wednesday and Thursday. && .SHORT TERM /THROUGH FRIDAY NIGHT/... Issued at 200 PM MDT Tue Jun 25 2024 Tonight...mid and perhaps some high level clouds move through from the west with dry weather expected. Low temperatures are forecast to be in the lower 60s to around 70. Wednesday-Wednesday night...a fairly well organized weather system moves off the Colorado front range and into far eastern Colorado by late afternoon, supporting 20%-40% chances for showers and thunderstorms. Overnight, this system continues moving east across the remainder of the forecast area with 40%-50% pops currently advertised. PWAT values increase into the 1.4-1.9" range with general storm motions to the northeast around 20 mph, supporting some beneficial rainfall amounts. High temperatures are forecast to be in the 90 to 95 degree range with low temperatures in the 60s. There will also be east to southeast winds gusting 20 to 35 mph during the day, strongest west of Highway 25. Thursday-Thursday night...showers/thunderstorms east of Highway 25 in the morning move away with 30%-50% chances for thunderstorms across the area in the afternoon. Thunderstorm chances increase into the 50%-70% range during the evening before this system moves east and away from the area after midnight. PWAT values hover in the 1.3- 2.0" range during the day and into the evening before slowly decreasing after midnight. 0-6km winds remain from the west- southwest at 20 to 25 mph, supporting another chance for beneficial rainfall. High temperatures are currently forecast to be in the upper 80s to middle 90s. Low temperatures are forecast to be in the lower 60s to around 70. Friday-Friday night...another weather system moves off the Palmer Divide and into far eastern Colorado adjacent counties west of Highway 27 in the afternoon with pops in the 20%-40% range, continuing east overnight with 50%-60% chances for showers/thunderstorms. High temperatures currently range from the upper 80s to upper 90s with low temperatures in the middle 50s to middle 60s. && .LONG TERM /SATURDAY THROUGH TUESDAY/... Issued at 103 PM MDT Tue Jun 25 2024 The upper-level high pressure system looks to remain in place over Texas for the long-term. A 250mb low pressure system over the Great Lakes will allow a ridge to extend from the high pressure system and cover the High Plains. This will cause the flow aloft to slowly shift from zonal to southwesterly over the weekend. Some weak 500mb shortwaves are possible in the afternoon hour Saturday and Sunday, but nothing very strong is showing up in the guidance. The weak shortwaves could provide us enough forcing for diurnal showers and storms Saturday and Sunday. Sunday looks less likely for convection due to the 250mb ridge amplifying. Guidance is showing a pretty strong signal that another trough will work into the northwestern CONUS Monday, causing stronger southwesterly flow during the mid-day Monday. This trough could cause enough forcing, and remove the ridge just long enough, to cause some moderately organized convection Monday afternoon and evening, but there is a lot of uncertainty this far out. After the trough moves through the area, likely late Monday night, zonal flow returns. Temperatures over the weekend will generally remain in the 80s to low 90s. Monday and Tuesday, temperatures will be int he 90s to low 100s. Monday has potential for being the next very hot day with heat indices approaching 103F. Overnight temperatures will only cool into the 60s, with Saturday night being the coolest. && .AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/... Issued at 518 PM MDT Tue Jun 25 2024 For KGLD & KMCK...
