The National Weather Service, North Little Rock, is reporting the recent spate of mild weather and the increase in moisture brought with it has primed the skies for thunderstorms Sunday afternoon and evening.

An arriving cold front from the west will introduce a line of thunderstorms beginning in the west at 5 to 7 p.m. The front will advance across Arkansas through the evening, reaching the Mississippi River Monday morning.

The service is calling for a possibility of severe weather, “mainly west of Little Rock” this evening. “Strong to damaging winds will be the main concern,” the service reports.

The state has two risk areas, a Slight risk area from central Arkansas to the west, as far north as Van Buren County then in a east-west line running just below Fayetteville. A marginal area is north and east of this, running as far east as Jonesboro.

“Slight,” in weather service terms, shows a possibility for short-lived but intense storms, possibly tornados, with isolated hail as large as 1 inch. “Marginal” is less severe storms with winds up to 60 mph, low tornado risk and hail up to 1 inch. The highest risk in the warning map shows for damaging winds.
