An upper ridge, warming temps aloft, and downslope flow will lead to well above average temperatures across southern Colorado today (Thursday), with highs across the plains reaching the low 60s, and slightly cooler conditions in the mountain valleys. The region will also remain dry, with mainly light winds. Friday will be even warmer, with highs reaching into the 70s across parts of the plains! Dry air and a lack of recent precip will combine with breezy winds to increase the fire danger for Friday. However, winds will not support widespread critical fire weather conditions. High fire danger will again be present across parts of the plains on Saturday, with temperatures remaining in the 60s. By Saturday, an upper trough will dig into the southwest U.S. and bring winter weather impacts to southern Colorado. The continental Divide will begin to see accumulating snowfall early Saturday, with snow spreading from west to east across the mountains through the day. The upper level energy will develop into a closed low and lift northeast across southern Colorado through Sunday. Surface low pressure will deepen in southeast Colorado as a result, eventually advancing to the northeast. This system will draw a cold front south down the eastern Colorado plains Sunday morning. Along/behind the front, gusty winds and accumulating snow showers are appearing likely, again, sometime in the Sunday morning - afternoon timeframe. While the most intense snowfall appears more likely north of the forecast area, gusty northerly winds combined with the snowfall could lead to a period of hazardous travel with reduced visibilities and slick roads. More specific timing and snow totals will be available as the event draws near. Sunday will be significantly cooler, with highs only in the 30s.
