Your Weather Briefing for Northwest Arkansas
Weather Briefing Last Update: 4:30 p.m. cdt Wednesday, June 19, 2019

Late this afternoon, skies around northwest Arkansas were mostly sunny to partly cloudy. It was a breezy afternoon with wind speeds in the 9 to 18 mile per hour range. Temperatures late this afternoon had warmed into the lower and mid 80s. An isolated thunderstorm will be possible late this afternoon and up until about sunset this evening across northwest Arkansas, in the vicinity of a weak frontal boundary. Any thunderstorm which might develop would have the potential to be strong to severe with damaging winds and large hail the main concern. Although, the latest model data suggest the greatest threat for severe weather will be from far southeastern Oklahoma, into central, and southern Arkansas this evening. Meanwhile, high pressure settles over northwest Arkansas later tonight with a return flow and upper level high pressure ridging keeping Thursday very warm and dry. There is a slight chance of showers and thunderstorms spreading across portions of northwest Arkansas late Thursday night into early Friday morning.

Looking ahead to Friday afternoon into the upcoming weekend, a building ridge of high pressure will result in humid and warmer weather. By Friday into Saturday, high temperatures will climb into the upper 80s to lower 90s across northwest Arkansas. In addition to the warmer temperatures, dewpoints climbing into the lower 70s will be a prime recipe for sticky weather across northwest Arkansas with heat index values pushing into the 95 to 105 degree range. As we settle into a southwesterly flow pattern by Saturday, a few mid level weather disturbances will once again translate through the central U.S. bringing a chance for scattered showers and thunderstorms Saturday night into Sunday. Forecast models continue to differ on exact solutions, thus some varied solutions on timing and location of potential rainfall exist into early next week.
