The warm weather that spawned springtime longing Saturday and Sunday morning was short-lived, as the temperature dropped 18 degrees in about 40 minutes Sunday afternoon.

6News meteorologist Jennifer Schack said steady rain would last most of Sunday evening and would turn to snow overnight. The rain and colder temperatures could cause roads to freeze, while she predicted a snowfall of 1 1/2 inches.

“After midnight, it will cool off enough to change into snow. The potential is there for some accumulative snow late tonight,” she said. Schack said temperatures will fall into the 30s Sunday evening, reaching 29 degrees. The high for Monday is expected to be 32, with winds from the northwest gusting between 15 and 20 mph.

The Lawrence area is under a winter weather advisory from 9 p.m. Sunday through 6 a.m. Monday. A flood watch is in effect until midnight Sunday.
