SHORT TERM. (This evening through Tuesday) Issued at 228 PM MDT Mon Jul 26 2021

At the beginning of the short term period, the CWA is under a large upper air ridge covering the western CONUS with the controlling upper air high in northeastern CO. The upper air flow varies in a clockwise fashion across the CWA due to the proximity of the upper air high on Monday. At the surface, the remainder of Monday through the night looks to be mostly dry with minimal chances of precipitation. A brief isolated rain shower or non-severe thunderstorm cannot be completely ruled out as there is one currently in northern Gove county. The latest HRRR run does not predict any precipitation, but the RAP and NAM show brief bouts of precipitation in the CO counties and the adjacent counties during the evening. Again, any storms that may pop up should stay below severe criteria as current convective parameters do not support severe weather. Surface winds in the CWA expect to be from the south around 10 to 15 mph for the rest of the day before becoming lighter and south-southeasterly into the night. The CWA should see temperatures near the 90 degree mark for the remainder of the afternoon then see overnight low temperatures in the lower to upper 60s.

For Tuesday, the upper air pattern looks to stay pretty much the same as that on Monday as models show the upper air high barely moving eastward and remaining in northeastern CO throughout the day. At the surface, current model runs aren't showing lower visibilities due to fog in the morning so will not be adding them into the forecast. The main concern for the day will be the above normal temperatures with heat indices exceeding the 100 degree mark in some areas as there looks to be a low chance for precipitation for the CWA. A Heat Advisory has been issued for Hitchcock, Red Willow, Decatur, Norton, and Graham counties from 17Z-01Z as the heat indices might have the potential to reach criteria though it seems marginal at this time. This will be monitored in case the situation changes to favor higher indices in the CWA. Daytime high temperatures in the CWA on Tuesday expect to be in the lower to upper 90s with forecasted heat indices in the lower 90s to the lower 100s. Tuesday's overnight lows look to be between the middle 60s and the lower 70s.

LONG TERM. (Wednesday through Monday) Issued at 200 PM MDT Mon Jul 26 2021

Wed-Fri: An expansive upper level ridge, extending eastward from the Intermountain West into the Central Plains, will persist through the duration of the work-week. Expect dry conditions and above normal temperatures . warmest on Wed and Thu. when heat indices may approach 105F.. and a heat advisory may be needed for eastern portions of the area (mainly east of Hwy 25).

Sat-Mon: Long range guidance suggests that the aforementioned ridge will amplify over the Intermountain West and extend northward through western Canada (Alberta/Saskatchewan) -- and that shortwave energy rotating around a large cyclonic gyre over Nunavut/Hudson Bay/Quebec may progress southward (along the eastern periphery of the amplifying ridge) into the Upper Midwest -- the net effect of which would bring the mid-latitude westerlies (NNW-NW flow aloft, in this case) in closer vicinity to the Central/Northern Plains. If this is the case, a somewhat greater potential for diurnal convection may exist . though. with an increasingly amplified/dynamic synoptic pattern at high- latitudes . confidence is below average. particularly at a range of 120-168 hours.

AVIATION. (For the 06Z TAFS through 06Z Tuesday night) Issued at 945 PM MDT Mon Jul 26 2021

VFR conditions are expected to prevail through the TAF period at KGLD and KMCK terminals. Light south winds continue through the overnight hours, then shift to the southeast by 20z, gusting around 20 knots or so through 01z.
