Isolated to scattered thunderstorms will be possible later this afternoon and through the evening hours. Some storms could be strong with gusty winds, frequent lightning, and small hail. In addition, there is the potential for a squall line of storms to move south out of Arkansas late today and bring locally severe wind gusts, especially across the Arklamiss. Otherwise, expect hot conditions with peak afternoon heat index values around 100 degrees. .DAYS TWO THROUGH SEVEN...Saturday through Thursday... Isolated to scattered thunderstorms will again be possible Saturday afternoon into the early evening and some of these storms could be strong with gusty winds, frequent lightning, and small hail. Cristobal, currently over the Yucatan Peninsula, is expected to move north through Gulf of Mexico this weekend and make landfall along the Louisiana coast Sunday night as a tropical storm. Showers and a few thunderstorms associated with the outer bands of Cristobal will begin to increase across the region late Sunday, before becoming more numerous by Monday as this system moves inland. As it does so, the threat for strong winds, locally heavy rainfall, localized flooding, and even a few isolated tornadoes will be possible Monday, especially over the Arklamiss. Keep in mind these impacts may shift west or east, depending on the eventual exact track of this system. These showers and embedded thunderstorms will begin to diminish from west to east Tuesday as the remnants of Cristobal lifts north out of the region. Finally, the threat for isolated to widely scattered showers and thunderstorms will exist Tuesday night and Wednesday near and ahead of a weak cool frontal passage. .SPOTTER INFORMATION STATEMENT... Activation of emergency management personnel...amateur radio operators...and storm spotters may be needed for this afternoon into this evening. Please relay any information about observed severe weather to the NWS while following all local, state, and CDC guidelines.
