Sunday Update: The Front Range Forecast: Wandering Thunder

In Brief:

Warm temperatures and afternoon storms set up.

Sunday Update:

Temperatures are quite warm this week with moisture coming into the state from the Gulf. We'll see afternoon thunderstorms most days with a bit more of a cool down and more water Wednesday with a brief cool front passage.

Spring is settling in.  I'm thinking that any I-25 snow, between now and June, is looking very unlikely.

End Sunday Update.

The Forecast Discussion:

A short wave ridge is moving in pushed by a short wave trough (Figure 2) that will rapidly warm us up this weekend (Figure 1), then brings fairly strong winds to the Front Range (Figure 3) Monday and Tuesday. See the Longer Range Forecast, below, for the end of the week.

The Longer Range Forecast:

The next 5 days sees precipitation (rain and snow - Figures 4 and 5) confined to the mountains. A broad trough and cut-off low moves in for the end of the week bringing us an extended period of cool wet weather.  I don't see any snow for I-25 folks through mid-month. Was that "it" for snow this side of Summer?
