In Brief:
With northwest flow aloft for a bit longer, we have one more notable front this week. This front comes through Wednesday afternoon followed by showers overnight into Thursday. After that, we warm up to summer levels with afternoon storm chances. June 1st IS the beginning of meteorological summer (even if June 20th is the start of astronomical summer).
Forecast Discussion:
Let's look backwards before we look forwards. That was a very nice wet storm. Figure 1 shows the actual rainfall pattern for the storm - it matches the GFS's forecast very well. Denver, Boulder, and Colorado Springs were the big winners with over an inch of water. Looking at individual gauges in Boulder county, Longmont saw 0.70 to 1.00 inch across town. Boulder saw around an inch to 1.40 inch - Figure 2.
High pressure settles in for a couple of days (Figure 3) before...
The Longer Range Forecast:
There is one notable cool front coming in Wednesday afternoon. It will only shave about 5 degrees off of temperatures but brings in a chance of showers Wednesday night into Thursday AM. After that, we return to very warm temperatures (hovering around 90F) with afternoon storm chances. It will feel and look a lot like summer.
Note, if all goes well, this will be the last discussion on the Longmont Observer. The next forecast discussion should appear on the Longmont Leader.
