Forecast Discussion:
Saturday was a near picture perfect day for Veterans Day. We saw very mild temperatures, very little wind, and just a few clouds. There is a weak cold front moving into the state Saturday PM and Sunday AM (Figure 1). This is in response to a small short wave trough moving through the pretty strong westerly jet stream flow over the state all this week (the red line in Figure 2).
By midday today (Sunday- Figure 3) the front will be far to the south and we'll see weather about 10 degrees cooler than we did on Sunday. Sadly, this is a very dry front.
The longer range forecast:
Another weak trough will move over the state on Tuesday. This will kick up some winds (more up in the mountains) and cool us just a bit. Still, it will be very dry (Figure 4). The very next day another ridge (blue line) is overhead and the front is gone (Figure 5). The deeper trough out west will move through on Thursday and bring down yet another front, but that one may have enough moisture to bring snow and rain showers to the mountains (not much on the Plains at this time). We'll watch that to see if it might put water down on Longmont.
