The National Weather Service office in Little Rock has issued a Freeze Watch for a part of North Arkansas, including counties of Baxter, Boone, Fulton, Izard, Johnson, Logan, Marion, Newton, Pope, Searcy, Sharp, Stone, Van Buren, Arkansas, Washington, Madison, Benton, and Carroll. This Freeze Watch will be in effect from late Friday night through Saturday morning.
A cold front is expected to move through the region from the north on Thursday and Thursday night. The front will be followed by a large area of Canadian high pressure, which will move over Arkansas Friday night and Saturday morning. Given a mostly clear sky and light winds under the high, temperatures are expected to drop to well below normal levels.
Below freezing temperatures are likely in the Ozark Mountains of the north and portions of the Arkansas River Valley and the Ouachita Mountains of the west. The watch includes locations from Cave City, Clinton, and Booneville northward. The watch may need to be expanded into Central Arkansas if it appears freezing temperatures will occur and persist for more than an hour or two.
These conditions could kill plants and tender vegetation left outdoors without protection. Unprotected water popes could freeze, especially if left without running a slow steady stream of liquid.
