Weather Authority Alert Day issued for Thursday, April 11

Thursday Afternoon Update

We’ve seen plenty of cloud cover, drizzle, rain and fog so far.

That’s kept the atmosphere stable enough to prevent storms to this point. Any breaks of sun will create an unstable atmosphere, raising the threat for severe weather between 5 and 10 p.m.

Below is a look at the worst-case scenario regarding storm potential Thursday evening.

Damaging wind gusts are the main threat from these storms. Those winds could cause power outages so be sure to have batteries and a flashlight on hand Thursday evening. High winds even last later into the week.

Flooding is also likely due to rain that reaches more than an inch in many spots in less than 24 hours.
