In Brief:
Mild weather continues with tiny chances of precipitation.
Friday update:
Things remain very quiet and mild (for this point in Fall). The chilliest day in the future will be Thanksgiving day itself, when temperatures return to normal briefly (Figure 2 update). There are very small chances of showers this weekend, the night before Thanksgiving and the following weekend. We will probably set the record for the latest measurable snow after all. When those small chances occur, the northern mountains will pick up some nice snow. Enjoy the pleasant weather unless there are showers on Saturday!
End Friday update:
Tuesday Update:
The front is blasting down the Front Range currently and a bit of moisture and uplift will occur in the mountains. Figure 1 update shows the expected snow overnight. Look close, it is hard to see. We "may" have a coating or dusting in the morning, but probably not. We are still in the running for a record late snow and record period of snow-less weather in Denver. It WILL be pretty chilly for the next.
End Tuesday update.
Forecast Discussion:
A giant ridge over the west keeps us very warm through Tuesday (Figure 1). A strong cold front arrives Tuesday around sunset, temperatures plummet and precipitation chances rise (see the Longer Range Forecast below).
The Longer Range Forecast:
A pretty strong trough sweeps the nation and brings down some cold Canadian air on Wednesday (Figure 2). At present, the area of snow this storm will kick up is very limited in coverage (Figure 3). The precipitation will be confined to the northern Colorado mountains and a few spots on the Plains (Figure 4). The snow in the mountains might be pretty impressive but with only a dusting apparent at lower elevations (Figure 5). The latest recorded measurable snow in Denver is November 21 which occurred in 1934. Looking further out, we might just break this record if this storm does not hit the airport.
