The episode as NWS GLD wrote it up.
In the late afternoon of the 24th, storms formed east of Denver and continued east-southeast. As these storms neared Kit Carson, CO, a single storm became stronger than the nearby storms and produced 1.75 inch hail.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Goodland, KS wrote its last area forecast discussion before the first event at Apr 24, 4:53 PM MST, 1 hour 57 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Goodland KS 553 PM MDT Thu Apr 24 2025 .KEY MESSAGES... - Shower and thunderstorm chances continue through Sunday. - Locally dense fog possible early Friday morning. - Below normal temperatures tonight through Saturday. - Potential fire weather concerns across eastern Colorado Sunday afternoon and south of Interstate 70 Monday afternoon. && .SHORT TERM /THROUGH SUNDAY NIGHT/... Issued at 135 PM MDT Thu Apr 24 2025 Tonight...cant rule out a few showers/thunderstorms this evening but the better chance may be after midnight as the GFS/NAM/HRRR models bring some mid level moisture into the southwest parts of the forecast area. Overall precipitation chances are in the 20%-40% range. There may also be some fog and we're watching for the potential for dense fog. Low temperatures are forecast to be in the middle 30s to middle 40s. Friday-Friday night...it will be a cloudy period due to a saturated boundary layer. Once again, the 700-500mb layer is rather dry during the day with increasing moisture overnight from the southwest. Daytime precipitation chances are in the 20%-30% range which may be a bit optimistic. Overnight precipitation chances are in the 30%-60% range. High temperatures are currently forecast to be in the 50 to 60 degree range. If the NAM/GEM models verify, high temperatures could be about 5 degrees colder in the middle 40s to middle 50s. Low temperatures fall into the upper 30s to middle 40s. Saturday-Saturday night...morning precipitation exits the area to the east during the day. I'm not terribly excited about precipitation chances given the amount of dry air aloft moving in, leaving us once again dependent on moisture below 700mb to generate precipitation. Right now, rainfall chances are in the 30%-50% range which may be optimistic. South to southeast winds quickly increase through the day with gusts up to 45 mph. Breezy southerly winds continue overnight. Overnight, the GFS model has a weather system moving through from the southwest, aiding in deepening the moisture column. Current precipitation chances are in the 30%-60% range. High temperatures are forecast to be in the 60 to 65 degree range with low temperatures in the middle 40s to lower 50s. Sunday-Sunday night...showers and thunderstorms (20%-50% chance) are possible during the day, along and ahead of a dryline mainly in the vicinity of Highway 27. Breezy to windy conditions continue with southerly winds gusting up to 40 mph. GFS/GEM models show favorable 0.5-1km wind speeds and 0-2km lapse rates for blowing dust based on local research findings. However, given steep (unfavorable) 2-2.5km lapse rates, its unlikely the dust would be confined closer to the ground and instead would easily lift and dissipate into the atmosphere so for now will not include a blowing dust mention in the forecast. High temperatures rise into the lower to middle 80s. Overnight, the dryline exits the area and we should be precipitation free. Gusty southerly winds through midnight slowly decrease while veering to the southwest and west. Low temperatures fall into the lower 40s to near 60. && .LONG TERM /MONDAY THROUGH THURSDAY/... Issued at 135 PM MDT Thu Apr 24 2025 Monday...as an upper level trough axis (oriented northeast to southwest) approaches the area during the day, moving into the area during the night, there will be enough moisture in the 850-500mb layer to support a 20%-30% chance for showers mainly north of a line from Flagler to Norton. West winds gusting up to 35 mph are possible west of Highway 27 during the day. High temperatures range from the lower 70s to lower 80s with low temperatures in the middle 30s to middle 40s. Tuesday...as Monday nights trough moves through, we watch to our northwest as another trough approaches. Presently, no precipitation is expected. It will be cooler with high temperatures in the 60s. Low temperatures are forecast to be in the upper 30s to lower 40s. Wednesday...as another upper trough moves through, there will be a 20%-50% chance for showers and thunderstorms. High temperatures bounce back into the 70s with low temperatures in the 40s. Thursday...there is currently a 20%-30% chance of showers with high temperatures in the middle 60s to lower 70s. && .AVIATION /00Z TAFS THROUGH 00Z SATURDAY/... Issued at 545 PM MDT Thu Apr 24 2025 Conditions will deteriorate at both terminals late this evening as low stratus /MVFR-IFR ceilings/ envelopes the region from north to south. Further deterioration to LIFR (most likely in association with ceilings) is expected at both terminals Friday morning. Improvement will be slow to occur on Friday.. and substantial improvement appears unlikely until early-mid Friday afternoon.. near the end of the 00Z TAF period. ENE winds at 5-10 knots will back to the NE-NNE and increase to 10-15 knots late this evening and persist through Friday morning. Winds will veer to the ENE-E Friday afternoon.. near the end of the TAF period. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...None. CO...None.
