Colorado 35-Day Outlook — April 8, 2026

The Pattern in Brief

The dominant story over the next three weeks is a warm anomaly locked over the Front Range and southeastern Colorado, with the Western Slope running cooler and drier. This east-west split is consistent across all three reliable forecast weeks.

Temperature: Weeks 1–4

Week 1 kicks off warm, with departures of +3 to +6°F across the Front Range and +6 to +9°F near Pueblo and Trinidad. The Western Slope sits near normal to slightly below.

The warm signal intensifies in Week 2. The southern Front Range and SE Colorado are the core of the anomaly, with departures potentially exceeding +9°F near the Pueblo–Trinidad corridor. This is the strongest signal in the forecast window — confidence is moderate to high.

The anomaly relaxes but remains warm — +3 to +6°F on the Front Range. The western half of the state stays cooler than average.

By late April the warm anomaly shrinks to a residual signal near Colorado Springs and Pueblo. The pattern is transitioning — confidence drops considerably at this range.

Precipitation: Weeks 1–4

An active pattern for central and eastern Colorado — +0.25 to +0.5 inches above normal per week. The Western Slope runs dry.

The wet signal continues for the eastern half of the state. The east-west dryness contrast persists.

The wettest week of the period for the northern Front Range and northeast Colorado — departures of +0.5 to +1.0 inch above normal. Western Slope remains dry.

The precipitation pattern becomes more mixed. Eastern plains stay modestly wet; the Western Slope picks up some moisture.

Bottom Line

Eastern and southern Colorado face a persistently warm, active April — good news for soil moisture recovery on the eastern plains, though warm temperatures may accelerate snowmelt in the mountains. The Western Slope sits in a drier,
cooler air mass through most of the period.
