General Discussion:

Colder temperatures will play a big role in the beginning of the weekend, staying relatively the same as they’ve been the last couple of days. These temperatures will start to increase come Sunday, going into the mid-60s. Expect to see clouds in the sky all weekend, slowly increasing with time as we head into fall break.

Key Messages

• Temperatures will remain cooler (48°F) Saturday before winds shift to a southerly flow, encouraging warm air advection to warm our area back up Sunday (67°F)
• This weekend will be mostly dry, but a chance of showers (10%) will be a possibly Sunday evening

Currently, clouds are working their way out of our forecast area, courtesy of NW winds through the entire troposphere. This will get rid of the overcast conditions we witnessed today, although clouds will still be a theme we see through the forecast period. There is a surface high pressure system in association with a large upper-level ridge located over southern Missouri, which will be moving ESE with time. This high has been the cause of the northerly winds we’ve been experiencing, which has added a chill to the breeze.

On Saturday, as the surface high pressure propagates ESE with time, winds will shift to a southerly component, which will give Columbia a bit of a warm up (Upper 40s) compared to the trend of the last week. Due to the shift of winds, moisture transport will provide increasing cloud cover as Saturday rolls on. This shift to southerly winds will also prohibit temperatures overnight Saturday from dropping significantly (42°F).

An upper-level trough is forecast to move eastward across the Rockies over the weekend, promoting cyclogenesis in eastern Colorado by Sunday morning. This, in association with the high pressure system previously mentioned, will strengthen the pressure gradient at the surface which will induce warm air advection. These winds are forecasted to strengthen (20-25mph) out of the south, which will also help promote moisture advection throughout Sunday. By Sunday evening, a shortwave and an associated surface low will be pressing into Missouri. A cold front is draped southwest of the surface low, and will drift through the region Sunday night into Monday morning. Ahead of the front, we are expecting to see a low chance of precipitation (10%) with little to no accumulation. Although these katafront showers are a possibility, increasing cloud cover is the primary trend with this front rather than precip.
