DISCUSSION

Issued at 1133 AM CST Fri Jan 30 2026

Cold air advection is forecast to continue into the weekend in the wake of today's cold front. Additionally, skies are forecast to clear overnight, which will likely support some radiational cooling early Saturday morning. This combination will likely allow temperatures to fall to the mid 30s to low 40s tonight.

Mostly sunny skies Saturday will likely allow temperatures to climb back into the upper 50s to mid 60s Saturday afternoon, in spite of the continued northerly winds. More efficient radiational cooling Saturday night will likely result in colder temperatures early Sunday morning, with low temperatures briefly approaching freezing across the northern portion of the CWA. The freeze watch remains in effect for Saturday night into Sunday morning.

Southeasterly winds are forecast to return Sunday afternoon, ushering in a gradual warming trend early next week. High temperatures look to return to the 70s Monday and the upper 70s to low 80s Tuesday. Another cold front is possible mid week, bringing cooler temperatures back to the area through the end of the forecast.
