UPDATE. Issued at 920 PM MST Sat Dec 14 2019
Dense freezing fog being reported at KITR presently. Numerous model visibility forecasts support dense freezing fog developing and lasting through about or shortly after sunrise Sunday morning for Cheyenne and Kit Carson counties of Colorado, Sherman, Wallace and Greeley counties of Kansas. Have issued a Dense Fog Advisory as a result.
Not terribly impressed about precipitation chances the rest of the night. Cant rule out something light across the northeast and eastern zones through sunrise before drier air moves in from the northwest putting an end to any chances.
UPDATE Issued at 515 PM MST Sat Dec 14 2019
Numerous model visibility forecasts are advertising freezing fog redeveloping around 03z or 04z continuing through about 12z mainly for areas along and south of the interstate although Cheyenne county Kansas is also included. These areas will see limited chances of snowfall and will have upslope flow with low clouds near the surface. Have added areas of freezing fog for now with visibilities around 1/2 mile possible. Could certainly see dense freezing fog but will wait a bit longer to see if it actually materializes.
SHORT TERM. (This evening through Sunday) Issued at 224 PM MST Sat Dec 14 2019
Forecast focus is on the snow expected across the forecast area staring late this afternoon and continuing through early Monday morning.
One of the difficulties in forecasting for this event is there is not a single low pressure system driving the snow expected across the forecast area. Instead, there are several waves moving through a large scale upper trough that will be moving east of the Rockies and across the Central High Plains region between this evening and Monday. The initial weak short wave trough is moving out of northeast Colorado and southeast Wyoming and eastward across southwest Nebraska and northwest Kansas beginning late this afternoon and continuing through this evening. The next stronger short wave trough moves across a similar area during the day on Sunday with the deeper upper trough expected to move across the region along a more southerly track from southeast Colorado and northeast New Mexico through Western Kansas. The end result is the northern sections of the forecast area will see snow beginning late this afternoon and evening that then transitions to a more southerly track across the southern part of the forecast area on Sunday. While overall QPF and resulting snow amounts have been tapering off with each of the last several model runs, there is currently a band of enhanced snowfall rates moving through the BOU forecast area towards the northwest corner of the GLD forecast area that could produce some impressive snowfall rates if it remains intact over the next several hours. This would necessitate the need for a forecast update to include mainly a greater snowfall amount across the northern sections.
With QPF and snowfall amounts on the decrease, the main area of snowfall remains mainly south of Interstate 70 and over the far east between Norton and Hill City through the weekend with generally around one inch of snow expected in those areas by early Monday morning. Elsewhere north of Interstate 70, locations are looking at one half inch or less of snow. In addition to the snow possibly producing lower visibilities across the area, the potential for areas of fog is showing up in a variety of locations across the forecast area over the next couple of days. Confidence is low at most locations for the formation of the fog with higher confidence in fog showing up around the MCK area tonight.
The main upper trough moves east of the area by late Monday with the upper ridge over the western U.S. moving into the Rockies by Monday night. Temperatures remain cold Sunday and Monday with highs only in the 30s and lows in the teens. Winds are expected to remain mostly light as the surface low that consolidates east of the Rockies on Sunday tracks east through Texas with high pressure remaining at the surface over the Central High Plains Region. Even with mostly light winds, wind chill values do manage to dip down to around zero over eastern Colorado Monday night into early Tuesday morning.
LONG TERM. (Tuesday through Saturday) Issued at 130 PM MST Sat Dec 14 2019
Exceptionally quiet in the long term period with no precipitation forecast and temperatures near to slightly above normal. Upper ridge will move across Tuesday and Wednesday. Upper low will kick out of the west on Thursday, but GFS and ECMWF in poor agreement on its track, though neither model is producing much in the way of precipitation. GFS solution would result in windy conditions Thursday and Friday, but otherwise can see little to no impacts. A strong upper ridge rebuilds for the weekend.
AVIATION. (For the 06Z TAFS through 06Z Sunday night) Issued at 1010 PM MST Sat Dec 14 2019
KGLD, sub vfr cigs/vis expected from taf issuance through about 14z. Winds from the southeast gusting 25kts early becoming 6kts or so after 09z. After 15z vfr conditions return with winds becoming northwest then north at speeds around 10kts, maybe a bit higher in the afternoon.
KMCK, sub vfr cigs expected through the period. Sub vfr vis expected through 13z. winds generally from the east under 10kts at taf issuance becoming light and variable from 14z through the rest of the period.
