NWS Goodland, KS wrote its last area forecast discussion before the first event at May 14, 1:26 PM MST, 1 hour 14 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Goodland KS 226 PM MDT Tue May 14 2024 .KEY MESSAGES... - There is a marginal risk for severe thunderstorms this afternoon. The main hazards will be strong wind gusts and hail up to one inch. Blowing dust may also be possible with any strong thunderstorm winds. An isolated landspout cannot be entirely ruled out. - Additional chances for showers and thunderstorms will be possible Wednesday through early Thursday morning. - Low chances for showers and thunderstorms Thursday, Saturday, Sunday, and Monday. && .SHORT TERM /THROUGH FRIDAY NIGHT/... Issued at 223 PM MDT Tue May 14 2024 For the rest of this afternoon, expect temperatures to climb into the 80s in most locations. A boundary has set up, extending from Trenton, Nebraska to Goodland, Kansas to Kit Carson, Colorado. This can be seen on visible satellite and faintly on radar. A couple of storms have developed near the boundary in eastern Colorado. Showers and thunderstorms are expected over the next several hours, moving west to east. Models are showing the potential for two rounds of thunderstorm activity. The first round will move through the area this afternoon and could produce some strong to severe thunderstorms. The main concerns will be hail and wind; however, a landspout may also be possible near the boundary. The second potential wave of storms will move through late this evening into early tomorrow morning. Wednesday, an upper trough moves into the region. Cooler temperatures are expected, with highs in the low to mid-70s. Additionally, showers and thunderstorms will be possible. There is a chance that a few areas could get some decent precipitation out of them. Thursday, a few lingering chances for rain will be possible in the morning. There may be a few isolated showers or storms in the afternoon, mainly for areas south of the interstate. Temperatures will be slightly warmer with highs in the mid to upper 70s. Friday, a pattern change will bring dry weather to the region. Westerly flow will set up over the region as a broad upper trough moves in from the PACNW to the Dakotas. High temperatures are currently expected to be in the 80s for most areas. && .LONG TERM /SATURDAY THROUGH TUESDAY/... Issued at 1235 PM MDT Tue May 14 2024 A dry and warm start to the extended period is forecast as the area looks to be between two systems. Warm area looks to be in place across the SW CONUS and then spread northward through the High Plains. High temperatures in the 80s are currently forecast. Dew points are currently forecast in the 30s to 40s which should help keep heat indices below the actual air temperature therefore mitigating any potential heat risk concerns. However due to this being one of the more warmer couple day stretches we have seen so far this year, some may not be quite acclimated to the warmth. I do have some concerns for how warm it actually be as moisture will remain in place. GFS also has a surface high in place with with NNE winds which may advect in cooler air from that area; the climatological days that usually give us the warmest air are when southerly or southwesterly winds are present. The latter portion of the extended looks to become more active as a trough sets up across the SW CONUS emanating multiple waves of energy across the Plains. Moisture currently does look to be in place for showers and storms, perhaps severe. Currently the more favored day for severe weather looks to be Monday as a surface low develops across SW Kansas. GFS forecast soundings indicate 2500 j/kg of MUCAPE and 0-6 shear in excess of 40 knots. PWATS will also be on the increase Sunday night on through the new week so will need to keep an eye on excessive rainfall potential as well. The potential active pattern does look to continue for the majority of the week as SW troughing remains in place. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1140 AM MDT Tue May 14 2024 VFR conditions are expected at both terminals through the forecast period. There will be a chance of showers and thunderstorms in the vicinity of the terminals beginning later this afternoon and continuing into the evening and overnight hours. There is a possibility of two waves of storms, the first occurring this afternoon/evening, and the second occurring around daybreak. Any storms will result in wind shifts due to outflow and the possibility of some blowing dust. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...None. CO...None.
