This Hazardous Weather Outlook is for a Large Part of Arkansas.

.DAY ONE...Today and Tonight

Showers and thunderstorms are in the forecast through tonight.
The potential does exist for some strong and severe storms later
today and tonight, mainly across northwest Arkansas. Damaging
winds will be the main threat, although an isolated tornado or two
cannot be ruled out. Locally heavy rainfall will also be a
concern.

.DAYS TWO THROUGH SEVEN...Thursday Through Tuesday

Thunderstorms remain in the forecast Thursday, some of which may
become strong to marginally severe. The potential for additional
locally heavy rainfall will continue on Thursday.

Ahead of a strong cold front, southwesterly winds will increase
across the eastern half of the state on Thursday. Boaters should
exercise caution on area lakes and rivers.

In the wake of the strong cold front, much colder air will move
into the state by Friday. Wind chill values in the single digits
will be possible Friday morning across northern Arkansas.
