Area Forecast Discussion National Weather Service Goodland KS 934 PM MDT Thu Sep 30 2021 .SHORT TERM...(This evening through Friday night) Issued at 219 PM MDT Thu Sep 30 2021 Satellite imagery and 500mb RAP analysis showed almost southerly flow above the High Plains today on the eastern side of an upper trough. This trough appeared to be digging into the Desert Southwest, closing off into a low in the process. At 1 PM MT, cloud cover had shifted off to the northeast and south, allowing clearing across the central portion of the region. Northerly winds continued at the surface, gusting around 30 mph at times, with temperatures in the 60s. For tonight, south to southwest flow persists aloft as the aforementioned low pushes further into the southwestern CONUS. Dry weather is anticipated with low temperatures in the 40s to low 50s. Cloud cover may creep back into the area ahead of the disturbance as early as the overnight hours. On Friday, the system ejects towards southwestern Kansas, resulting in rain showers and perhaps a few thunderstorms moving into the region from the south. While there is a chance for precipitation south of I-70 in the afternoon, the better opportunity for the entire area will be Friday night as the disturbance draws nearer to the High Plains. Severe weather is not expected with any thunderstorms that develop. This should tend to be more of a steady rain rather than convective, so am not anticipating flash flooding issues at this time. High temperatures are currently forecast in the mid 60s to low 70s. However, with cloud cover building in through the day, this may be a little warm. This is followed by dropping to the mid 40s to mid 50s for Friday night. .LONG TERM...(Saturday through Thursday) Issued at 132 PM MDT Thu Sep 30 2021 Precipitation will be fairly widespread during the morning hours at the start of the period with H5 low to the south of the area lifting northeast through the day. Eastern CWA remains in favorable WAA/Isentropic upglide with respect to low circulation through 18z, so expect a fairly persistent area of precipitation to develop. As system moves away from the area Div Q fields indicate strong forcing for subsidence and with limited residual instability, expect a pretty rapid decline in precipitation after 18z. H5 low will continue to the east and merge with another system forming new closed low system over the southeastern CONUS. Ridge will amplify across the area in response to this system and one approaching the four corners in an omega like pattern. While this pattern will be transient and not an Omega block, net result will be area once again under the influence of upper level ridge and associated warmth and generally quiet conditions. Although temperatures will be above normal, highs will generally be seasonal in the mid 70s. && .AVIATION...(For the 06Z TAFS through 06Z Friday night) Issued at 920 PM MDT Thu Sep 30 2021 KGLD and KMCK expect to see VFR conditions throughout the 06Z TAF period. KGLD starts with westerly winds around 5 kts before becoming light and variable at 16Z. At 00Z, KGLD winds become southerly around 5 kts then turn west-southwesterly with vicinity showers possible at 02Z. KMCK begins with northwesterly winds at 5 kts before becoming northerly around 7 kts at 18Z. At 20Z, KMCK winds become northeasterly around 6 kts then turn easterly by 23Z. KMCK may also see showers possible just beyond the TAF period. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE. NE...NONE. && SHORT TERM...JBH LONG TERM...JRM AVIATION...076
