LITTLE ROCK, Ark. – The Flash Flood Watch was cancelled early Wednesday morning. The Upper-level low will be moving over Arkansas Wednesday and Thursday, so periods of rain. and at times heavy rain, will continue, but the National Weather Service feels widespread heavy rainfall will not occur and the Flash Flood Watch is no longer warranted. Regardless, stay weather aware.
Tuesday, 4:20 a.m.
LITTLE ROCK, Ark. – A Flash Flood Watch is in effect for much of Central, Southwest, and Central North Arkansas until 7 p.m, Wednesday. Monday most of far West Arkansas received over one inch of rain. Mena received 3.50″!
Since Monday, a few counties in NWA have been dropped from the Flash Flood Watch and counties have been added in Central, Central North, and Northeast Arkansas as model consensus is that the heavier rain will begin to impact the eastern part of Arkansas rather than the western half.
An upper-level low will establish itself and circulation in Oklahoma Tuesday, and then the center of that circulation will be near Fort Smith Wednesday. This is a different position than model guidance gave Monday which had the low centering itself in the DFW Metro. The rainiest areas associated with upper-lows are on the eastern side of them. So, instead of West Arkansas, Central and East Arkansas will become rainier. For some residents in West Arkansas that already picked up multiple inches of rain Monday, this is good news.

Monday, 7:35 p.m.
LITTLE ROCK, Ark. – A Flash Flood Watch has been issued for the western half of the state of Arkansas until 7 p.m Wednesday.
This part of the state has already seen ample rainfall over the past few days, stretching back to last week. Parts of southwest Arkansas has picked up 4-6 inches of rain. Super saturated soil will lead to the potential for flash flooding to occur in these areas as runoff from additional rainfall will not seep into the ground.
A large area of low pressure will remain almost stationary over Oklahoma and northern Texas Tuesday and Wednesday. Due to the counter-clockwise wind flow of a low pressure system, a stream of moisture from the Gulf of Mexico will flow from south to north. With a moisture-rich environment in place, rain and storm development is likely to be scattered in nature across Arkansas (and many other neighboring states to the east) for the next few days.
Forecast models have trimmed back on large rainfall estimations. Our meteorologists predict an additional one to three inches of rain across central and west Arkansas over the next 48 hours. There may be localized higher amounts recorded, especially where thunderstorms produce downpours.
