944 FXUS63 KGLD 091741 AFDGLD Area Forecast Discussion National Weather Service Goodland KS 1141 AM MDT Sun Jun 9 2024 .KEY MESSAGES... - Sunday and Monday are forecast to be near to below average in temperatures with highs in the 70`s and 80`s. There are a few chances for storms in Eastern Colorado during the evening hours, with a low chance for a severe storm or two on monday. - Potential break in the active weather pattern mid week with near triple digit temperatures. - Next system looks to impact the area Friday or Saturday. && .SHORT TERM /THROUGH MONDAY NIGHT/... Issued at 121 AM MDT Sun Jun 9 2024 Today is forecast to start out a bit foggy and cloudy with the low levels remaining saturated from the recent rain and little to no dry air advection. As long as winds remain from the east and provide a slight upslope flow, fog should form within the next few hours by 10Z. The fog would then persist until a few hours after sunrise as temperatures start to heat up and slight ridging helps provide subsidence. The remainder of the day would see mostly sunny skies and highs in the 70`s with the saturated air and slightly cooler air mass over the area. There could be a chance for a few storms and showers in Eastern Colorado, but the lack of forcing and slight subsidence should keep most of the area clear. Tonight, skies are forecast to start mostly clear with lows dropping into the 50`s. Later in the night, low stratus clouds and fog may begin to form again, especially over higher terrain in western portions of the area. Low level flow is forecast to have a southeasterly component while ample moisture remains over the area. Tomorrow, slightly warmer temperatures are forecast in the 80`s with sunny skies and the colder air mass pushing off to the east. The ridging from the prior day is forecast to be short lived as a shortwave trough is forecast to through the Northern Rockies and help push lower surface pressure into more of the Plains. For the daytime hours, this could allow winds to be a bit stronger around 20- 25 mph. During the evening hours, storms could develop with the additional forcing in the region and try to push east. The forcing still looks to be rather weak with the surface low forecast to be broad, but the higher terrain should aid storm development. With forecast instability and shear on the weaker side (MLCAPE around 1000 J/KG and effective shear around 20 kts), severe storms aren`t likely, but there is a chance one or two could move through far Eastern Colorado. Storm chances are then forecast to lower going east and into the night with the low instability. However, the increase in cloud cover is forecast to keep lows a bit warmer in the upper 50`s. && .LONG TERM /TUESDAY THROUGH SATURDAY/... Issued at 1234 AM MDT Sun Jun 9 2024 Upper low pressure will move through the OK/TX Panhandle region Tuesday morning, followed by high pressure building in over the Four Corners region through mid-week all the while low pressure meanders off the West Coast. It`s during the latter part of the work week this upper low begins its inland progression, breaking down the ridge, and allowing a return of more active weather to the area. East-southeasterly upslope sfc-850 mb flow will draw in ample moisture for storm development - current guidance suggests PWAT values climb into the 1-1.75 inch range across the area for Friday. Further details on strong to severe storm potential late in the work week into the weekend are uncertain at this range, so continue to monitor the forecast. Tuesday will begin a warming trend with highs forecast in the 80s. With ridging really getting underway mid-week, will be looking at afternoon highs in the 90s. Temperatures late in the work week and over the weekend drop slightly - into the mid 80s to lower 90s. Overnight lows are forecast in the upper 50s to middle 60s. Regarding shower/storm chances for the period, chances will linger into Tuesday morning-afternoon before a drying trend thereafter - at least until Thursday evening-night when we`ll see daily chances return through the remainder of the long term period as the next system nears and subsequently moves through the area. && .AVIATION /18Z TAFS THROUGH 18Z MONDAY/... Issued at 1135 AM MDT Sun Jun 9 2024 VFR to MVFR conditions forecast for the TAFs. Light winds today will continue. Tonight there may be LLWS for KGLD and KMCK around 6z. There does not look to be much of a change in the wind direction until toward 12z. During this time low clouds, maybe even fog, will approach Goodland from the west. Some model data has the clouds down to IFR levels at Goodland. KMCK will be well east of the fog/low clouds. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...None. CO...None.
