The Front Range Forecast: Still Continued Calm + Heat

In Brief:

Quiet late summer weather this week with very warm temperatures.

Tuesday Update:

Other than a tiny return of moisture in early October, we remain dry and warm for the next 10 days (Figure 2 update). Record high temperatures for the end of the month range from 90F to 92F.  We will be close but probably not set record highs in many locations.  Hope for a bigger cool down and return of rain starting October 3rd.

End Tuesday update.

Thursday Update:

The next ten days will see a remarkable lack of temperature variation (about 5-10 degrees above normal) and virtually no chance of rain.  There is nothing to see here. What you saw today, you will get all week.

The Forecast Discussion:

A slow cool down begins this week (Figure 1). The normal high temperatures drop from 78F to 74F over the next 10 days. We start out above normal, but drop to normal by next weekend.  That warmth is due to the big western U.S. ridge in place at the start of the forecast period (Figure 2). Rain chances remain very low all week.  There is just a chance of an afternoon storm now and then.  This is a great week to get a roof replacement (we are scheduled for this week).

The Longer Range Forecast:

Over the next 5 (Figure 3) and 10 (Figure 4) days, rain totals are very low and spotty state wide.  Nothing much to discuss here! Fall is coming!
