Rain, heavy at times, will target areas from Texas to Ohio, including cities such as Little Rock, Ark., and Louisville, Ky., through Monday. Repeated episodes of heavy rain could push some rivers and streams out of their banks and residents in flood-prone areas should be prepared.
A persistent weather pattern over the last couple of weeks brought an abundance of rain from the mid-Mississippi Valley northeastward to the Ohio Valley.
Alex Sosnowski recently wrote that Little Rock, Ark., has received over 13 and a half inches of rain from the 15th through the 27th of November. This amount is nearly six times their normal rainfall for the period and is three times their normal rainfall for the entire month of November.
Several more inches of rain will fall across the Little Rock area through Monday. A similar fate will be found in areas farther southwest in northeastern Texas, and areas to the northeast surrounding the Ohio River, including Louisville, Ky.

Flooding will primarily target small streams and rivers along with any low-lying and poor-drainage areas. Although the rain will bring abnormally high levels in the Mississippi River this week, no significant flooding is forecast from the river.
By Tuesday, the rain will head into the Appalachians while diminishing in intensity. Only a few showers will linger by Wednesday from southeastern Texas east-northeast toward the Carolinas. The break Tuesday and Wednesday should allow any swollen small streams and rivers to retreat to lower levels.
Unfortunately, one more round of rain is possible, perhaps heavy at times, Wednesday night in Arkansas to the Tennessee Valley on Thursday. Enough cold air could even get wrapped in with the moisture to change the rain to snow for a period of time from eastern Arkansas and western Tennessee.
