LOUISVILLE, Ky. (WHAS11) -- The Louisville area is expected to be hit with two waves of storms as severe weather is expected to move through the region Sunday.

According to the WHAS11 Storm Team and the Storm Prediction Center, The first round of storms (non-severe/strong) is started moving through the area in the early morning with heavy rain, lightning and gusty winds up to 40 mph. This first round of showers/storms will end by early afternoon (1-2PM).
 
Look for a small break (2-4PM)...If we see any sun during this time temperatures will climb (instability) and our risk for tornadoes will increase, especially in S. Indiana. If we stay cloudy all day the threat for severe weather decreases, but we will still see the afternoon/evening squall line.
 
The second round is very concerning...with the chance for damaging winds and isolated tornadoes. SPC has upgraded a small section of our area to a HIGH risk for this afternoon/evening (See attached map). SPC says "a tornado outbreak with multiple significant tornadoes & widespread damaging winds expected" in this HIGH risk area. With that said...the greatest threat of this happening will be north towards Indy.
 
Here is what to expect with the line of storms:
- Squall Line Strong to Severe Storms
- Slight chance of isolated tornadoes ahead of squall line (Dependent upon amount of sunshine)
- Damaging Winds Gusts 60-75 mph
- Isolated quick spin-up tornadoes possible along the squall line

Timing of PM Squall Line
- 4-7pm NW Counties
- 5-8pm Metro
- 7-9pm SE Counties
- If isolated tornadoes do develop timing would be about an hour earlier than squall line

Wind Advisory
- Winds will increase by late this morning outside of any storms
- 11am-Midnight
- S 15-25 Gust 40mph
