Flooding concerns are increasing across NW Arkansas and the River Valley over the next few days due to multiple rounds of rain.
A blocking pattern across the eastern United States is providing the necessary setup for a rainy week. This pattern is called an “omega block” due to its shape, with low pressure to our west and high pressure to our east funneling plenty of moisture into the southern Plains.
Current forecasts call for the heaviest rain to be mainly in eastern Oklahoma and the River Valley. Overall, we expect widespread 2 to 4 inches over much of the NW Arkansas/River Valley region. Locally higher amounts are possible if storms persist over the same area.
The rainfall will not be consistent throughout the week. Many will see breaks in the rain, perhaps even a few breaks in the clouds. However, some of the rain may be heavy at times. The Weather Prediction Center (WPC) has placed NW Arkansas and the River Valley under flash flood risks for the next couple of days.
The greatest risk for flash flooding across the region will be Tuesday morning through Thursday morning.
The National Weather Service (NWS) has placed Le Flore County in Oklahoma and Scott County in Arkansas under a flood watch until 7AM Thursday. Keep in mind, additional counties may be added over time.
Low Severe Weather Potential
The Storm Prediction Center (SPC) has placed our area under a marginal (level 1/5) risk for severe storms.
Monday Overnight – Tuesday Morning
The day 1 Convective Outlook from the SPC keeps the greatest severe weather risk to our west. However, a few strong storms could hold together as they move into NW Arkansas and the River Valley Monday night.
Tuesday Morning – Wednesday Morning
The day 2 Convective Outlook puts our region in a level 1/5 (marginal) risk again. A few storms could be strong across the region, however, the ingredients for severe weather do not appear to be very high over the area at this time.
