Hazardous Weather Outlook National Weather Service Little Rock AR 500 AM CDT Fri Apr 28 2017 ARZ003>007-012>016-021>025-030>034-037>047-052>057-062>069-291000- Boone-Marion-Baxter-Fulton-Sharp-Newton-Searcy-Stone-Izard- Independence-Johnson-Pope-Van Buren-Cleburne-Jackson-Logan-Conway- Faulkner-White-Woodruff-Scott-Yell-Perry-Polk-Montgomery-Garland- Saline-Pulaski-Lonoke-Prairie-Monroe-Pike-Clark-Hot Spring-Grant- Jefferson-Arkansas-Dallas-Cleveland-Lincoln-Desha-Ouachita- Calhoun-Bradley-Drew- 500 AM CDT Fri Apr 28 2017 This Hazardous Weather Outlook is for a Large Part of Arkansas. .DAY ONE...Today and Tonight A warm front will gradually lift northward over Arkansas today, then become nearly stationary across northern to north-central Arkansas. As an upper level weather system moves through the region, showers and thunderstorms will develop mainly north of Little Rock, especially during the late evening and into the overnight hours. Isolated to scattered strong to severe storms will be possible near the frontal boundary, with large hail and damaging winds the main threats. An isolated tornado may also be seen. Areas of heavy rain will also be seen especially over northern Arkansas, which could lead to flash flooding across the area. This weather will continue tonight over the northern half of Arkansas. .DAYS TWO THROUGH SEVEN...Saturday Through Thursday Severe thunderstorm chances will continue on Saturday, mainly in the afternoon to evening, as Arkansas will be in the warm sector with an approaching cold front. Large hail and damaging winds will once again be the main threats, with an isolated tornado possible. The potential for heavy rainfall will also exist, increasing the concern for flash flooding and river flooding. Expect 3 to 5 inches over mainly the northwest and northern half of the state with isolated heavier amounts Saturday through Sunday. The widespread and very heavy rain may produce life threatening flash flooding. Also, area river levels will rise, and some river flooding will be possible. Interests along area waterways and rivers should monitor the weather closely this weekend due to the threat of possible flooding. Forecast details are still being fine tuned, including where the stationary front will set up today and Saturday, and the timing of the rounds of very heavy rain. Please continue to monitor the latest forecasts from your National Weather Service concerning this potentially serious situation. .Spotter Information Statement... Spotter activation will likely be needed Friday evening and again Saturday evening, and possibly Sunday due to the forecast of severe weather and the flash flooding and river flooding potential. && Visit NWS Little Rock on the web.
