The Front Range Forecast: Mostly quiet and warm

In Brief:

Late Spring weather settles in with only a weak cold front cooling and bring moisture Monday.

Forecast Discussion:

Things are quite warm and quiet as we sail through the weekend (Figure 1). There will be a return of wandering afternoon thunderstorms for the weekend.

The Longer Range Forecast:

The next 'system' is weak cold front pushed by the trough approaching from the west in Figure 2. Temperatures do drop below normal, but don't even approach freezing (Figure 1).  At this time, the weatherunderground model has about 1/3rd of an inch of liquid falling. The GFS gives us 1/10th to 1/4th of an inch.  Thunderstorms may drop locally heavier totals.

For fun, I included the snowfall forecast.  It is only the highest elevations that will see falling flakes.
