893 FXUS63 KGLD 261050 AFDGLD Area Forecast Discussion National Weather Service Goodland KS 450 AM MDT Thu Jun 26 2025 .KEY MESSAGES... - Mild weather is forecast today with clear skies and lighter winds. There could be a few sub-severe storms this afternoon and evening. - Another round of potentially severe storms are expected Friday afternoon into the evening hours. && .SHORT TERM /THROUGH TONIGHT/... Issued at 1220 AM MDT Thu Jun 26 2025 The remainder of the early morning hours are expected to see storm activity lower and push east of the area as the air becomes more stable, outflows push off to the east, and the upper shortwave also shifts east. With the remnants of showers and storms upstream in Central Colorado, skies are forecast to remain cloudy through the night and help keep temperatures generally in the 60s. For today, a fairly mild day is forecast for the area as the upper pattern over the area is forecast to be somewhat zonal, keeping the flow weak. With the weak flow, winds are forecast to be lighter around 5 to 15 mph tomorrow. Sunny skies are forecast for the area due to marginally drier air that is forecast to push into the area, allowing temperatures to warm into the mid to upper 80s. Late in the afternoon and evening, there is the possibility of a few storms as guidance hints at a very weak upper low upstream of the area with a weak surface low pushing through the area. On top of causing the winds to slowly shift to out of the east during the day, these features may allow some storms to develop either over the higher terrain in Eastern Colorado or along convergence boundaries. With the drier air in place, storm coverage and intensity are forecast to be fairly low, potentially with no storms forming at all. If storms did form while the surface low pulled in some more moisture, we could see storms pop up across more of the area along outflow boundaries. Even then, storms would be unlikely to be severe or long lived. Tonight, some cloud cover could linger if storms managed to form, but otherwise mostly clear skies are forecast. Winds are also forecast to be light as the pressure gradient weakens. With this, low temperatures should cool to near dewpoints around 60 degrees. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... Issued at 1255 PM MDT Wed Jun 25 2025 A weak shortwave trough sliding through the lee side of the Rockies and a weak surface low over southeast Wyoming and western Nebraska will tap into a marginally unstable atmosphere across the western and northern portions of the CWA to produce some isolated convective activity late Friday afternoon into Friday evening along a weak dry line boundary. Any storms that form should be very short-lived and isolated as a lack of moisture and limited deep layer forcing will keep updrafts from sustaining themselves for any long period of time. Temperatures will also be significantly warmer on Friday as the drier airmass easily heats up into the low to mid 90s. The heat will be on this Saturday as a weak shortwave ridge builds over the area. Increased subsidence will limit cloud development and allow highs to climb into the upper 90s or a good 10 degrees above average. Although overall rain chances will be low, there could be enough heating to overcome a weak capping inversion aloft by the late afternoon and evening that will support an isolated thunderstorm. If storms fire up, they could produce some gusty winds due to the dry airmass in place aloft. Heading into next week from Sunday through Wednesday, a deepening longwave ridge over the western third of the CONUS will allow a deep layer northwest flow regime to take hold in the upper levels. Unfortunately, this sets up a decent pattern for a series of mesoscale convective complexes to form over eastern Wyoming and western Nebraska and then sweep to the southeast across the forecast area each evening as the system follows the theta e axis. Confidence on this scenario is a bit lower than average, but is something we need to monitor over the next couple of days as both a heavy rainfall and severe weather threat could accompany any MCS that forms. The northwest flow pattern will allow for cooler temperatures to filter in with highs cooling back into the mid 80s for next week. && .AVIATION /12Z TAFS THROUGH 12Z FRIDAY/... Issued at 443 AM MDT Thu Jun 26 2025 This morning, both KGLD and KMCK have a chance at seeing MVFR ceilings until about 15-16Z. However, for KGLD, any cloud deck looks to be very sparse, so no TEMPO was included. KMCK has been in and out of MVFR over the past couple of hours, and also has a slim chance to see some patchy fog add to the MVFR conditions. Winds through the period will start off favoring the northwest, before northeast, and eventually southeast by tomorrow morning. Winds look to be generally weak, so I opted to go with variable instead of noting each 60 degree change. The light, easterly winds tomorrow morning could allow fog to form around KMCK, but not enough confidence exists to put it in the TAFs. There is a <5% chance KGLD and KMCK could see some storms around 23-2Z, so keep an eye out for that! && .GLD WATCHES/WARNINGS/ADVISORIES... KS...None. CO...None.
