Severe Storm Timeline – Flooding and Damaging WindsFebruary 19th, 2014 at 11:14 pm by Robb Ellis under Weather
Heavy rain and strong storms are expected on Thursday, and it brings several threats along with it. Here’s a look at a timeline of what you can expect from these storms and when they’ll arrive.
Scattered showers with potential for heavy rain north of Indy in the morning. Temperatures will likely be above freezing and warm up quickly. Winds of 15 to 25 mph will keep temperatures rising. A rumble of thunder could be possible in the morning, but we aren’t expecting the greatest threat for severe weather until later in the day.
A brief lull in the heaviest rain is likely, though a few showers will still be ongoing. A few isolated thunderstorms may develop in southern Indiana. Temperatures will be very warm, likely near 60 degrees. Winds will be breezy (20 to 30 mph with gusts to 40mph) throughout the day. Some sunshine may be possible through afternoon.
A strong line of storms will roll through in the evening. This line will contain gusty winds and heavy rain. Some of the storms may contain gusts over 58mph (severe criteria) and while the threat for tornadoes isn’t high, an isolated tornado can’t be ruled out.
In addition to the immediate threat of severe weather within the line of storms, heavy rain will lead to some flooding. Street and creek flooding will be a concern immediately after the rain, but river flooding will be an ongoing concern as rain runs off and more snow melts.
The line of storms will exit before midnight, but the flooding threat will continue, especially along rivers.
