Forecast Discussion:

The front is sweeping down the Front Range this evening, Wednesday. We've had enough rainfall to wet the ground.  Hurray!

I'll update briefly in the morning with the rainfall and snowfall reports.

Rainfall update in Figure 1A... Longmont got enough water to make a puddle... well most of us did!

Figure 1a: Rainfall reports for the 24 hours ending 1/11/2018 at 7am from CoCoRaHS.

The longer range forecast:

Temperatures go back above normal today and get even warmer beyond that for the next 10 days (Figure 1). There is a small storm passing on Friday and another prolonged unsettled period from Sunday PM to Tuesday... but neither are very wet or cold.

Just for fun - let's look at the GFS and the next 10 days. Figure 2 has Longmont as the pink dot- and it only gives us 1-2".   Someone needs to do some sort of mystical snow ritual for us!

Figure 1: The 10 day graphical forecast for Longmont. Notable storms and the temperature trend is here.

Figure 2: The GFS snowfall total forecast for the next 10 days. Longmont is the pink dot.
