In Brief:
Weather remains cool and stormy (afternoons) for two more days (the rest of Monday and Tuesday). We get hot and dry for Wednesday and Thursday (90F more more Thursday???). Cooler 70'sF and showers return Friday through Sunday. Severe weather is not expected around Longmont through Thursday (but updates will show up here).
Forecast Discussion:
The cool front is still here (stationary) and the trough is still overhead. Afternoon showers are drifting around Monday (severe to our east) and will return (non-severe) Tuesday (Figure 1).
We might pick up 1/3rd of an inch of rain depending on where storms wander Tuesday (Figure 2).
The Longer Range Forecast:
After this, we get a very short, 2 day visit from summer (Figure 2). That is due to a ridge that will move rapidly by Wednesday and Thursday (Figure 3 - blue line to our east).
The trough to our west moves in for the weekend and we go back to the current pattern (Figure 2). The GFS gives us about 1/2 inch of water over the next 5 days (Figure 4). The NAM seems to be about 0.3-0.4 inch over the same time period (Figure 5).
