Forecast Discussion:
The moisture is here (Figure 1)! For Loveland, Ft. Collins, and Denver - it came in with a bang (thunderstorms). Longmont saw light showers.
We can track the waves of arriving cold air by looking at my outline of the advancing cold air (thin black lines between blue and orange regions) in Figures 2 to 4. At noon on Wednesday, the cold air was just nosing down towards Ft. Morgan (Figure 2). By tonight the first blob of cool is sinking into Mexico while the next hit is on its way for Friday (Figure 3). For noon on Friday the next wave of colder air is past and things are pretty windy (Figure 4).
The total rainfall through Friday noon still is only a few hundredths of an inch of rain to maybe a one or two tenths (Figure 5).
The longer range forecast:
That cool air slides out for the weekend and we briefly return to upper 80's F for your time by the pool. Next week we drop to 70's F and eventually 60's F later in the week. There are some rain chances next week. We should see lows drop to the upper 30's F later in the week. More on that later!
