KEY MESSAGES

- Cooler and drier weather will develop this weekend into next week, with frost or a light freeze possible in some areas.

DISCUSSION

Issued at 133 PM CST Wed Nov 4 2026

Through Thursday: Local radars showed the last of the rain associated with a cold front moving through our CWA, just to the southeast of our CWA. A surface high to the northwest will settle over our region tonight into Thursday. This will bring in drier air in the wake of the cold front and allow temperatures to bottom in the 40s at most locations. Under strong radiational cooling tonight, patchy fog will be possible toward sunrise. The near zonal flow aloft tonight will become southwesterly Thursday. Combined with the surface high and near full insolation, temperatures will warm above normal, peaking near 80F in the southeast. /22/

Through early next week...

While the pattern will be substantially more suppressed heading into the weekend with high pressure and continental air largely in control, an active southern stream jet will provide for an opportunity for increased cloudiness and perhaps an isolated shower or two through early next week. Overall, though, most locations will stay dry and those that do see a brief shower won't see much. The next 7 days will likely be dry and cool as overnight lows average 5 to 10 F below climate normals for this time of year.

Lows temperatures at times will flirt with the mid to lower 30s F, particularly in some of the typically cooler spots. This could result in some chance for a light frost though most places likely manage to stay above freezing. The coldest night appears to come Sunday night before we begin a slow moderating trend (lows "only" down into the lower 40s F) into the middle of next week. Regardless, these near-freezing temperatures serve to remind that now is a good time to begin practicing those winter safety practices. Ensuring plants, pets, and people are considered for as nights begin to more routinely threaten frost/freeze. /LP/KP
