Area Forecast Discussion...CORRECTED National Weather Service Goodland KS 1126 PM MDT Sun Apr 30 2023 .SHORT TERM...(This evening through Wednesday) Issued at 234 PM MDT Sun Apr 30 2023 The Tri-State area is experiencing a pleasant Sunday afternoon as temperatures continue to warm towards the afternoon highs in the 60s. High pressure near the surface remains over the area tonight keeping us dry. Winds are expected to become light and variable across the area after sunset. This evening cloud cover is expected to increase over Eastern Colorado and move east through Monday morning as a weak band of moisture moves off the Rockies. Overnight low temperatures are expected to be in the 30s. On Monday the upper ridge is expected to continue moving east over the Rockies as the Omega Block synoptic pattern sets up.Dry conditions are expected to prevail through the first half of the week. Temperatures are expected to be in the 60s to lower 70s during the afternoon hours tomorrow. Overnight lows are expected to be in the 30s across the area Monday night. On Tuesday the upper ridge gets pushed over the High Plains as an upper low moves over the West Coast. The stream of moisture coming off the Rocky Mountain Snowpack is expected to expand over the western half of the area on Tuesday. Dry conditions are anticipated during the day with potential for diurnal showers and storms to develop along and south of a Yuma, CO to Leoti, KS line during the late afternoon to evening hours. Instability has decreased compared to the morning forecast package; however, PWAT values remain 0.5-1" for Flagler, Goodland, and Tribune in model soundings indicating heavy rain is still possible. High temperatures are expected to be in the upper 60s to lower 70s on Tuesday with overnight lows in the low to mid 40s. .LONG TERM...(Wednesday through Monday) Issued at 125 PM MDT Sun Apr 30 2023 Long range guidance continues to indicate that an omega block -- broadly characterized by ridging aloft (500-300 mb level) over the central CONUS and troughing aloft along the Pacific and Atlantic coasts -- will prevail through next weekend. In the lower levels, a relatively persistent surface to 850 mb ridge over the Lower MS River Valley and Deep South -- associated with synoptic subsidence on the eastern periphery of the central CONUS ridge / western periphery of the eastern CONUS trough -- will foster a prolonged period of low-level southerly flow /moisture advection/ from the Gulf of Mexico into the Southern and Central Plains throughout the period. In such a pattern, expect above normal temps and above normal chances for precipitation (convection). Guidance varies considerably w/regard to finer aspects of the upper level pattern -- [1] the orientation (and general evolution) of the central CONUS ridge and [2] eastern extent of cyclonic flow aloft over the western CONUS, in particular -- lending considerable uncertainty to forecast specifics, e.g. location, coverage, timing of.. and overall potential for.. convection). && .AVIATION...(For the 06Z TAFS through 06Z Monday night) Issued at 1055 PM MDT Sun Apr 30 2023 VFR conditions are currently forecasted at each terminal through the period. LLWS is observed on the VAD wind profile at KGLD so will include in the TAF. Uncertainty in how long this will last as guidance is struggling with this, will monitor through the night.Mid level clouds around 080 are forecasted to develop across the center portion of the area affecting mainly the KGLD terminal. Ridging will be set up across the area resulting in mainly clear skies and light winds less than 10 knots for the duration of the period. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE.
