Cool but dry weather is the story for Tuesday night and Wednesday day. A front comes through (dry) in the afternoon with wind and cooling temperatures. Clouds move in later in the afternoon followed by drizzle and then freezing drizzle overnight. Precipitation (with maybe a few flurries later in the night) comes to an end before dawn. Bridges and driveways and shaded spots might get pretty slick by morning Thursday. Drive safely before the sun warms things enough to melt that glaze. We stay cool and dry until another front might do this again Sunday afternoon into Monday.
A dry and not too cold cool front will blow things around Wednesday afternoon (Figure 1). Clouds will begin to increase a few hours later with light drizzle beginning in the evening. As temperatures drop below freezing, it will change to freezing drizzle (Figure 2 and 3). We only drop to the mid 20'sF Thursday morning. This isn't super cold. Bridges and cool roadway surfaces might be very slick for the Thursday morning commute. The sun will be out again by late morning Thursday and melt most of those spots. The total snowfall and rainfall over the next five days is below the minimal shaded threshold (Figure 4 and 5). This won't make much of a water impact.
The Longer Range Forecast:
We slowly warm until another front slides over Sunday afternoon. Will we get snow, or freezing drizzle Monday morning? We'll watch it all week.
I'm in Leesburg, VA for my annual work meeting - but I am watching Colorado from here!
