In Brief:
We rapidly warm up to above normal temperatures before the weekend and remain mostly dry for the next week.
Forecast Discussion:
We had a vigorous cold front slam us with winds, cold air, and snow down to about 9000 feet elevation on Monday. It was exciting. For rainfall, Longmont received about 1/2 to 2/3rds of an inch of rain where Boulder missed out a lot (Figure 1 in the gallery). You can see the progression of this abnormally cold air on Tuesday as it pushed out onto the Great Plains (Figure 2). By Thursday, we are getting warm and dry with high pressure at the surface (Figure 3) and a big ridge overhead (Figure 4). Forget rain and cool temperatures for the next week and more.
The Longer Range Forecast:
By Saturday, the ridge still dominates the middle of the country with southwest flow aloft over our state (Figure 5). The ridge is really tipped over with troughs passing the state to the north by the start of next week (Figure 6) - but we are still warm/hot and dry in the long term.
Over the next 5 days, random showers (I'm doubtful this much water will fall) may give us a trace to a 1/10th inch (Figure 7). Over the next 10 days, we maybe add another 1/10th inch, on average, around Longmont (Figure 8). More on storms we can't yet see in a future post! Stay cool.
