038 FXUS63 KGLD 230943 AFDGLD Area Forecast Discussion National Weather Service Goodland KS 343 AM MDT Mon Sep 23 2024 .KEY MESSAGES... - Low temperatures in the mid to upper 30s are forecast for eastern Colorado early Monday morning, potentially allowing for some patches of frost. - Near average temperatures and dry conditions forecast for the upcoming week. && .SHORT TERM /THROUGH WEDNESDAY NIGHT/... Issued at 125 PM MDT Sun Sep 22 2024 Current observations show the elongated upper low over the area as satellite shows clouds swirling over the area. The precipitation has largely moved out of the area, but could see a few additional showers in Eastern Colorado before the afternoon ends. Otherwise, temperatures are warming to the mid to upper 50`s with a few breaks in the cloud cover. This evening and through the night, the upper low is forecast to continue to shift further east and help bring in drier air in the mid-levels which will clear the cloud cover out across the area. While the skies are clearing, the surface winds are forecast to become light as the pressure gradient weakens heavily. With the clear skies and light winds, lows are forecast to drop into the upper 30`s and 40`s, near the dewpoints. There is still a very low chance for patches of frost in Eastern Colorado as temps drop into the 30`s. However, the recent rains are forecast to keep dewpoints a bit higher in the mid to upper 30`s, which will limit the chance for temps to drop to or below 36. If the winds are a bit higher than forecast, there is a chance that drier air can mix in and help lower temps to the mid 30`s. Tomorrow, a sunny day is forecast with dry air across the area. With the clear skies and relatively light winds, temperatures should be fairly warm in the mid to upper 70`s. Tomorrow evening, another shortwave is forecast to move through the Plains from the north and help bring some mid-level moisture and forcing. However, the dry air near the surface is forecast to limit the area to just an increase in cloud coverage and maybe some virga. Lows are forecast to be near 50 with the increase in cloud cover. && .LONG TERM /THURSDAY THROUGH SUNDAY/... Issued at 343 AM MDT Mon Sep 23 2024 As we move into the latter half of the week, a giant ridge extending across the Central to SW portions of North America in a semi-omega pattern. Both the GFS and ECMWF favor cut-off or closed lows developing on the southern ends of upper troughs that will pinch the side of the ridge closer over the Rockies and Great Plains. This pattern will unfortunately lead to dry conditions most likely through early next week. There is a cutoff system that sets up over the lower Mississippi River Valley. This system does meander and retrograde some late in the week. The ECMWF shows the best potential for some increased moisture to work towards the eastern CWA, but the overall trend keeps this east of the area. Temperatures throughout the long term are expected to be slightly above average for the highs and lows. High temperatures have been fluctuating between the mid 70s to lower 80s each day. Overnight lows could be in the mid 40s to lower 50s. && .AVIATION /06Z TAFS THROUGH 06Z TUESDAY/... Issued at 935 PM MDT Sun Sep 22 2024 KGLD...VFR conditions are expected through the period.
