(Tonight through next Thursday) Issued at 1031 PM CST Thu Feb 19 2026 The latest surface analysis places a 994mb low on the MO/IL border and stretching a cold front nearly parallel to the Mississippi River. The lift from this boundary has a narrow line of convection developing, apparent on KNQA. This convection is expected to remain tamed with gusty winds as the primary concern.

Temperatures will not warm much on Monday due to elevated northwest flow continuing to filter in cold air. Tuesday morning will be even colder as the surface high centers over us, lightening winds and clearing skies for a great radiational cooling setup. Probabilities of a hard freeze (
