Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – April 5, 2019

The forecast discussion:

We have entered a very warm and quiet period, so I'll save words here. The showers that came through Longmont just slightly wetted the ground. Figure 1 shows a few trace amounts reported. Oh well.

With moisture around and some little upper-level ripples passing over the state, we have a slight chance of a thunderstorm or two (quite weak) Friday afternoon/evening and Saturday afternoon/evening (a bit of a better chance).

The longer range forecast:

We climb into the 70's F for the weekend and start of the week before our next big change in the weather. Tuesday night, showers return and it cools enough that snow may return some evenings into next weekend. More on that later!
