Accumulations are already 5 inches above average for the year with Tuesday's 1.5 inches of rain, and heavy rain and thunderstorms are expected to make for another soaker Wednesday.

"The result is some river flooding," WRCB-TV Channel 3 meteorologist David Karnes wrote in his weather blog.

"Both Lookout Creek and Coahulla Creek are above their banks, and many others are coming close," Karnes said.

Looking ahead, "we will have a few light sprinkles on and off through the first half of [Wednesday]," he said. "[Wednesday] will also be breezy with winds from the south at 10-15 mph."

A flood watch is in effect across the area in anticipation of heavy rain through the day, he said.

"Overnight the rain will end, and Thursday morning will be dry with temps in the mid- to upper-40s," Karnes said. "The high Thursday will reach 56, and we may see a few showers lifting up through the area from the south."

There's a 40 percent chance of rain and it'll be warmer on Thursday.

"More rain will stream in through the day Friday," Karnes said. "Temps will range from 49 in the morning to 57 in the afternoon Friday."

Most of the rain on Saturday with be to the north and west of Chattanooga with the chance of rain at 30 percent.

While Saturday "may not be a washout, we will certainly see some pop-up showers throughout the day," Karnes said. "We will be warm Saturday. The high will reach a whopping 65 degrees."

Then, more rain will move in overnight into early Sunday morning, followed by drier conditions and a high of 61 Sunday afternoon, he said.

"Next week looks fairly dry and pleasant with highs right around 60 degrees," Karnes said.
