Things are quiet locally with a big warm up in store for us over the weekend. A ridge is moving overhead and a stationary front will push east as a warm front early today (Figure 1). The monster storm, now down in Texas, is headed to meet the cold air associated with the high pressure centered over Missouri and Illinois right now. Enjoy this wonderful weekend!
The longer range forecast:
By Sunday, we’ll see a ripple and weak cool front kick up mountain snows to our west, but in town, we’ll be high and dry. The monster storm is really dumping rain, ice, sleet and snow on the southeastern U.S. states by the end of the weekend (Figure 2).
Our next chance of snow comes with a cold front and upper air trough coming in on Wednesday night (Figure 3). The upper air trough looks pretty significant (Figure 4 – red line on top of us and cutoff isopleth overhead) with a good blob of surface precipitation over the region (Figure 5). Figure 3 still only forecasts about an inch of snow then. We’ll keep watching it, as always.
Long Range (fantasy) Christmas Forecast:
There still is no hint of a major snow storm between now and Christmas Day for Longmont. Christmas Eve and Day look to be in the 30’s F for highs and around 10°F for lows. Christmas Eve is cloudy while Christmas Day is clear. We’ll watch that too as the weeks pass.
