In Brief:
The forecast is becoming summer-simple: high temperatures around 90F each day with a greater or lesser chance of afternoon thunderstorms coming off the mountains. Our most stormy afternoons appear to be Tuesday (post day for this column) and Friday- Saturday. We do cool to the lower 80'sF briefly Saturday.
Forecast Discussion:
The dark green outline shows the deeper moisture (as it begins to move out of the state - Figure 1). The lighter green line outlines very dry air to our west. The chance of severe weather is marginal just north of Longmont up through Ft. Collins etc. (not shown).
The Longer Range Forecast:
We spend a few hours in the lower 90sF Wednesday and Thursday before we cool to the mid 80'sF then lower 80'sF Friday and Saturday. Afternoon storm chances are low, but still exist.
The 4th of July Forecast:
I have a red asterisks at about 9pm on the charts Figure 2 and Figure 3. The weatherunderground model has us at ab out 76F at 9pm with a 4% chance of showers and 25% cloud cover that is decreasing. The GFS based 7! Timer model (Figure 3) has us at about 63F with cloudy skies and showers occurring. It begins to clear after midnight. There is some clear disagreement - we'll keep an eye on it!
