Today: Low clouds and areas of freezing fog will blanket many areas on the plains of eastern Colorado for several hours this morning. The freezing fog has caused spotty roadways to ice up, be particularly mindful of the bridges and over passes early this morning. Lower elevations will remain quite cool, especially during the morning hours, and warm very slowly as the sky gradually clears today. In the meantime, much warmer air is moving overhead. Over the higher terrain where the sun pops out early this morning the air should warm relatively quickly, and in some cases the mountain communities will end up warmer than the plains. Late day high temperatures should reach the 40s and 50s for lower elevations along and north of the Arkansas River, but again, much of the day will likely be spent in the 30s and 40s. South of the Arkansas River, places like Walsenburg & Trinidad should warm into the 60s. We expect mainly 50s over our local mountain areas today. During the afternoon some areas will notice a pretty stout breeze, particularly over the far eastern plains.
Tonight: Another wave will bring mainly rain to the valleys, but a burst of heavy snow will fall over the high country tonight, and Winter Storm Warnings have been issued by the National Weather Service for the central and northern mountains. Although most of the heavier precipitation will fall along and west of the Continental Divide tonight, we do expect areas of rain and snow will drift out across the plains as well. Right now it appears the best chances for precipitation will exist over the Pikes Peak Region with the heaviest precipitation through just after midnight, but a secondary surge of cool air could kick of another round of scattered rain and snow showers late. The air overhead will be pretty warm tonight so for lower elevations we expect primarily rain showers, but some wet snow could fall at times over Teller County and the Palmer Divide. Over Teller County in particular as much as 1” to 3” of snow could accumulate on mainly cooler surfaces, but if any heavier bursts of precipitation drift overhead the roadways could briefly whiten up in spots overnight. Most areas won’t be as chilly tonight with low temperatures in the 30s to lower 40s area wide.
Extended: Sunday may start out a bit unsettled with spotty rain and/or snow showers leftover from the overnight wave, but precipitation should be winding down for most areas. Enough instability may exist for scattered showers, and possibly some thunderstorms to develop over the plains during the afternoon. The plains will be warmer with highs in the 60s for many areas. Any showers that may have developed Sunday afternoon should wind down Sunday night. Monday looks breezy and cool, but mostly dry. The air should begin to warm on Tuesday, and then Wednesday and Thursday look quite warm. The wind will increase as a cold front approaches by the end of the week likely leading to fire weather concerns again.
