The Front Range Forecast: Spring plus some moisture

In Brief:

Spring marches on with showers returning mid-week.

Forecast Discussion:

Our normal high temperature for this week is about 62F. We start the week somewhat above normal until a cold front arrives on Wednesday (Figure 1).

The Longer Range Forecast:

That cold front is driven down by an upper air trough (red line, Figure 2). We have a period of upslope flow behind a low slipping into Kansas (Figure 3). This should be a northern Colorado storm with a bit of nighttime snow along I-25 (Figure 4) and a bit of moisture north of Colorado Springs (Figure 5).

In the week beyond (Figure 1), we remain cool with chances of showers now and then.  More later!
