National Weather Service Denver/Boulder CO 236 PM MDT Fri Oct 28 2016 .SHORT TERM...(This evening through Saturday) Issued at 220 PM MDT Fri Oct 28 2016 Current satellite imagery showing continued diminishing cloud cover over the plains. Temperatures have gotten above the previous record of 80s degrees set in 1994 with lower 80s further east. Over the mountains cloud cover will increase through the evening as an approaching trough will bring a slight chance of showers to the mountains mainly north of I-70 and the Park range. Wet bulb zero temperatures will stay elevated but some rain and snow mixture will be possible down to 10,000 feet with rain below that. The plains will stay dry but increasing clouds overnight will keep low temperatures in the lower 50s. With the moisture moving into the mountains combined with increasing westerly winds isentropic packing will increase allowing for another mountain wave to form by tomorrow morning that will persist into the afternoon. Temperatures for Saturday will be cooler with passage of a weak front with highs in the mid 70s and 40s in the mountains. Continued dry conditions combined with breezy conditions continue to increase fire concerns over the plains. LONG TERM...(Saturday night through Friday) Issued at 220 PM MDT Fri Oct 28 2016 the strong high pressure ridge responsible for the dry and unseasonably warm weather of the past several days is projected to weaken midweek with the passage of a weakly organized upper trough tethered to a closed low over the nrn Baja Peninsula. Moisture appears limited at all levels with this system and the bulk of the forcing for ascent passes over Wyoming. In addition...models also show a weak sfc cold front sliding down acrs nern Colorado Tues night ushering in cooler temperatures for Wednesday. Any cloud formation with this frontal boundary should be limited due to the dry environment in place. Cooler temps on tap for Wed and Thu will still be above average but only by a few degs. During the day Thu models show the upper ridge regaining strength over the Rocky Mtn region aided by the potent upper level trough moving onshore out west. At the same time some of the models show the closed low over Arizona lifting northeast towards the Four Corners region. Its possible southwestern sections of the CWA could begin feeling the effects of this system by late on Thu in the form of increased cloud cover and showers chances.National Ag.
