We're continuing to track strong to severe storms set to impact the area this evening. The enhanced risk (level 3/5) has been extended into northeast Iowa, now including Mason City and Decorah.
The main threat with these storms is very strong wind gusts up to 70 mph that could cause damage to trees and buildings. Large hail over two inches in diameter (slightly larger than a golf ball) is also likely. You may want to cover your gardens or bring potted plants into the garage or closer to your house to protect them from being damaged.
Timing has now been pushed back about an hour from yesterday's forecast. Storms moving in from the northwest will begin to impact the area between 7-8 p.m. tonight, becoming more widespread as the night goes on.
This line of storms does look to be moving quite quickly which could limit rainfall totals. However, strong downpours are expected within these storms which could bring rainfall totals up to an inch in isolated areas. Widespread rainfall totals are expected to be between a quarter and a half inch.
Again, the storms will move out quickly so we'll be completely dry through Wednesday. Temperatures will be in the mid to low 80s, with dew points still near 60s. Temperatures and dew points will both be declining as we head through the rest of the week, so we'll be sitting more comfortably by the weekend.
