Just what we here in West Central Ohio need to hear right? As we venture through the weekend we’ll start things off with a partly to mostly sunny day on Saturday but by Sunday the chance for showers and thunderstorms will return.
The same stationary front that has been sitting to our south for the last 3 or 4 days will creep back northward as a warm front for the second half of the weekend. AS OF NOW it’s still up in the air as to how far this warm front will be able to lift north. The further north the front lifts, the better chance we will see for both more heavy rain and severe weather. Here is a look at the position of the front based on the RPM forecast model as of late Sunday. (Keep in mind, that I’m thinking any showers and thunderstorms on Sunday will probably be below severe limits.)
This front will be the boundary for a VERY warm and unstable air mass into next week. Due to increased heat and humidity CAPE values have the potential to be very high especially Monday here in West Central Ohio. Forecast models are still divided on how far north the front will make it on Monday. The GFS has the front the furthest north and brings the very unstable air mass into NW Ohio on Monday. Here is a look at the CAPE (Convective Available Potential Energy) values into Monday evening. Numbers above 2 or 3 thousand j/kg indicate the potential for an explosive storm environment. Notice much of the region is in the 3 to 4 thousand j/kg range.
When you couple that high CAPE with a warm front in the region that definitely catches a meteorologists attention! This scenario for Monday is still 3 days away and is definitely not set in stone, just something to watch over the next 24 to 48 hours to see if it pans out or not.
Here is a look at the NAM forecast model CAPE on Monday. Notice it’s shifted further west and south but still extremely high!
Basically the point I’m trying to make is that somewhere in the Southern Great Lakes region will be in line for a severe weather outbreak on Monday. It’s all dependent on where exactly that warm front sets up. You can bet I’ll be watching, especially Monday!
