Hazardous Weather Outlook...Updated National Weather Service Little Rock AR 745 AM CST Fri Jan 10 2020 ARZ003>008-012>017-021>025-030>034-037>047-052>057-062>069-111100- Boone-Marion-Baxter-Fulton-Sharp-Randolph-Newton-Searcy-Stone-Izard- Independence-Lawrence-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- 745 AM CST Fri Jan 10 2020 This Hazardous Weather Outlook is for a Large Part of Arkansas. .DAY ONE...Today and Tonight Showers and isolated thunderstorms remain in the forecast today. That will be followed by an outbreak of severe weather and a significant heavy rain event tonight and through the early morning hours Saturday. A large storm system approaching from the southern Plains will be responsible for the active pattern. Thunderstorms will begin developing in eastern Oklahoma and eastern Texas by late this afternoon, and will remain in place through the evening awaiting the arrival of the system. Once the system nears, a line of storms will kick to the east and move through Arkansas tonight. The incoming line of storms will likely bring widespread severe weather to the region. The main concern will be damaging winds, and there may be a few tornadoes as well. Where wind damage occurs, gusts may be hurricane force or higher. Ahead of the line, some data is indicating scattered thunderstorms in southwest Arkansas this evening. This will be monitored very closely, as storms such as these will have the potential to spawn tornadoes. Storms overnight will produce torrential downpours. Two to more than three inches of rain is expected to dump in much of the state. Given that vegetation is dormant and not consuming much ground water, downpours will runoff quickly, and this will increase the flash flood potential. This event will also feature windy conditions. South to southeast winds at 10 to 20 mph today will increase to 20 to 30 mph tonight before shifting to the northwest. Gusts could reach 40 mph in portions of eastern Arkansas. .DAYS TWO THROUGH SEVEN...Saturday Through Thursday Precipitation will gradually taper off on Saturday as colder air filters into Arkansas. Lingering light rain will change to light snow in the Ozark Mountains of the northwest. Some spots could pick up a half inch to an inch of snow, mainly on grassy areas. Roads will remain wet, with icy patches possible Saturday night as temperatures drop below freezing. .Spotter Information Statement... Spotter activation may be needed tonight and early Saturday. && Visit NWS Little Rock on the web. Go to https://weather.gov/lzk. 46
