Fall Temperatures Forecast for the Weekend, a Chance of Rain Too

It hasn't felt much like fall in recent weeks, but that should change this weekend. We're already experiencing cooler temperatures today ahead off our next upper level trough digging into the west. As clouds burn off later this morning we should see highs climb into the 70s, though they'll remain about 10 degrees cooler than Thursday for most locations.

A shortwave out ahead of the upper level feature will bring a decent chance for showers and storms to the urban corridor by this evening. The HRRR has showers developing along the Front Range by 4 - 5pm, then pushing east across the Plains overnight:

Not a huge amount of precipitation is forecast with any showers/storms that do develop, but a few locations could see ~1/4" of rain by later this evening:

Since you may be thinking, "snow?", we should clarify by saying that this isn't the weekend for the white stuff in the metro area just yet. However, the higher peaks will get snowed on with any system that pushes through from here on out. Think you know when Denver's first snow will arrive? Enter your guess here!

Troughing will stick with us through Saturday, and with that our weather will remain unsettled and cool this weekend. Highs both Saturday and Sunday are forecast to remain in the 60s for Denver, with overnight lows in the 40s. There will again be a chance for showers and storms on Saturday, with a lesser chance Sunday as drier air returns.

Next week will start drier and a bit warmer, but another upper level low is forecast to drop out of the Pacific northwest and dig into California early in the week. This will be the weather system we'll be watching for the Wednesday-Thursday timeframe as it's forecast to slowly trek east by midweek. This system certainly bears watching as it's forecast to dig a bit deeper and generally looks a bit more organized than this weekend's system. That being said, at the moment there's very little agreement on where this thing tracks – with the Canadian and European models taking it too far south for us, bringing a soaking to New Mexico and Texas instead. We'll see.
