If you think there’s been a lot of rain so far this year, you would be right.

Total rainfall in the region since January has been recorded at 33.06 inches, which put the region at 11.77 inches above the normal of 21.29 inches, according to Derek Eisentrout, meterologist with the National Weather Service in Morristown.

Eisentrout said the month of June was one of the months that recorded a high rainfall total.

“There were several storm systems that moved through. We were generally in a pattern, a wet pattern for this time of year, where we had more systems track across the region than what is normal,” he said. “The monthly total of precipitation for the Tri-Cities was 8.37 inches and that does set the record. The previous was 7.37 inches and that was set in 1998.The normal for June is 3.9 (inches), so you can see we were 4.47 inches above the normal.”

Eisentrout said during weather system that came through on June 18, the region received 2.9 inches of rainfall in a 24-hour period, an amount he said would cause flooding.

Information from the Climate Prediction Center website also indicates that the month of July could see above average precipitation alongside normal temperatures.

Eisentrout said rainfall already seen this week is expected to continue on throughout the rest of the work week.

“There’s (an) upper level low (pressure system) over West Tennessee today and what it’s doing is essentially ... streaming Gulf moisture over the area,” he said. “We’re in a generalized area of low pressure over the east United States and then the low over ... the Memphis area, or West Tennessee is going to ... pull moisture across the area. So, you mix moisture with low pressure and instability and you’re going to have chances of rain and showers and some thunderstorms about every day.”

According to the National Weather Service website, thunderstorms are likely today, with a 60 percent chance of rain and a high of 79 degrees.

Tonight showers and thunderstorms are predicted before 8 p.m. with a 60 percent chance of rain, with the low around 63 degrees.

Showers and thunderstorms are back again throughout the day and night Wednesday, with approximately a 70-80 percent chance of rain. The high Wednesday is forecast at 79 degrees and a low of 66 degrees.

According to the NWS website, the Fourth of July has a 70-80 percent chance of rain throughout the day, with showers and thunderstorms likely Thursday night, including some heavy rainfall.

Chances of rain start to decrease Friday, with a 50 percent chance of showers and thunderstorms and a high near 80 degrees. A 30 percent chance of rain is forecast for Friday night with a low around 65 degrees.

NWS also placed Northeast Tennessee under a flood watch beginning Wednesday afternoon and ending Friday afternoon.

A 20-30 percent chance of rain is expected for Saturday, with a high near 85 and a low near 67.

On Sunday, the chance of rain is forecast around 10-20 percent. The high Sunday is 87 degress, with a low around 67 degrees.
