In Brief:
Very warm and windy conditions return.
Saturday Update:
Very warm (70F today!) weather returns and the winds pick up again creating fire weather danger. We return to seasonable temperatures with low precipitation chances until we get to Thursday. The week-end storm looks fairly warm and not particularly wet, but I'll keep an eye on it here. Go out and play - it is beautiful out there!
End Saturday update.
The Forecast Discussion:
We have a few days of unusual warmth and wind creating red flag fire warning conditions (Figure 1). A strong, but fast moving, cold front hits Monday night. (See the Longer Range forecast below for more).
The Longer Range Forecast:
The approaching upper air trough stretches from Canada down into the Pacific (Figure 2). If this could have arrived as a cut-off low (as the models showed a week ago) - we could have had significant state-wide snowfall. But, it will move through rather quickly. The peak snowfall for the storm appears to center on lunchtime Tuesday (high sun angle will make sticking snow difficult to achieve - Figure 3).
Currently, the GFS (Figure 4) gives Longmont 2-4 inches. The NAM (Figure 5) gives us 1-3 inches with more quickly piling up closer to the mountains.
More later!
After that passes, it looks like we return to the 60's very quickly.
