Hold on, I'm looking something up... tedious, dull, monotonous, repetitious, unvaried, dry... OK those were synonyms for boring. Except for a slight chill and a couple of dry cold fronts, Longmont will see very little variation in the weather for the next week or more. That just means that exciting winter weather is building up for a big hit later this season! (I hope.)
Snow continues in the mountains with most to all ski resorts getting a daily addition of fresh powder (Figure 1). We'll see warming down-slope flow here with some gusty windy conditions this afternoon (Monday). The upper air pattern this week is very "zonal" or flowing west to east. There is a gentle troughniess in the West with small short waves embedded in the flow. These troughs aren't deep enough or slow enough to pull in moisture east of the Rockies (Figure 2). We remain dry.
The Longer Range Forecast:
We will see about 5-8 degrees of cool down from a dry cool front Wednesday afternoon and again Friday afternoon (Figure 3). The rest of the time we'll rise to about 50F each afternoon. Those fronts do mean that the mountains will see a bit more enhanced snow fall rates (good for them!).
The first front is approaching Tuesday night (Figure 4). The upper air pattern rebounds to a shallow ridge heading into Thursday (Figure 5) - allowing us to quickly warm again to 50F (watch for down slop winds every 'warm' day). Over the next 10 days the mountains see a foot to a foot and a half in the higher mountains, but no snow occurs down on the Plains (Figure 6).
