Rain chances and cooler weather behind our weekend front lingers today with our lowest high temperature of the recent summer in just the upper 70’s F. The front pulls away and we return to upper 80’s F for highs. Monsoon-like moisture returns Wednesday giving us afternoon storm chances again.
The Plains have been cooled by air flowing in from Canada, but a few storms may fire in the mountains and approach severe limits as far east as the I-25 corridor. The SPC (Figure 1 update) has painted the area as being under a Marginal Risk – for large hail and high winds. It looks like only a couple or a handful of cells will form that get that strong – most folks won’t see severe conditions.
End 7:30am Update.
Our weekend front finally begins to head to the east Monday night (Figure 1) after we see a high today (Monday) only around 78° F (Figure 2). Marginally severe weather might return in the afternoon (but is not currently expected). I’ll update here again if that changes. The GFS gives us about 1/2 inch of rain from Sunday afternoon to Monday evening (Figure 3). The wunderground model thinks we’ll see only about 1/3rd inch of water.
The Longer Range Forecast:
A big upper high sets up for a while in the southwest/four corners area (Figure 4). Tropical moisture will wrap around it into Colorado suppressing the high temperatures that might have occurred. This moisture will also mean afternoon storm chances return Wednesday – but highs struggle to break 90° F this week.
