Marching Out

Posted by: Buckey2745, 4:16 PM GMT on April 04, 2012

Winter. It's something we expect to see every year. Heavy snows.
Ice storms.
Cold early season rains.
Temps dropping below zero at least a few times. These are all things you invision when you talk about winter. But these are still things you can think of when you hit a transition month, like March.

Not this year.

It should come as no surprise after the relatively mild winter we had that something like this would happen. The warmest March on record.

When the NWS compiled the stats it was clear that our transition was non-existant. We went from a chilly February to a hostile March. Warm weather and intense storms marked our March.

When you start your March out with the second deadliest tornado outbreaks in the month, you know you're in for an interesting month. The March 2-3 Tornado Outbreak dropped 65 tornadoes and caused 39 deaths. One of the more interesting things I've seen came from just south of Cincinnati in Crittenden, KY when an EF4 hit that area. The NWS in Wilmington was able to capture this classic hook echo on terminal doppler, and did a nice job illustrating the anatomy of a supercell tornado:

While the tornado was a big story, it wasn't the main story last month. Record warmth was the norm, as record highs fell, and the all time record for warmest March on record fell. Here's a comparison of March over the past few years here in Central Ohio:

2008: 40.0°
2009: 45.5°
2010: 45.2°
2011: 42.9°
2012: 55.2°

What will April bring? My guess would be more of the same. Expect a bumpy rest of Spring.

April 1st: Another Slight Chance of Storms

Posted by: Buckey2745, 5:27 PM GMT on April 01, 2012

Another day, another chance for storms this afternoon. After Friday's system rolled through we were left with a cooler airmass in place. With a very strong ridge building in from the west we'll have a pretty good boundry layer this afternoon.

The SPC has us under a Slight Risk. The advancing warm front will clash with a backdoor cold front coming in from Canada, putting southern Ohio, Indiana and Northern Kentucky in the target zone:

ILLUSTRATED: Warm front advancing from the west, backdoor cold front, dying MCS dropping southeast through Kentucky. Highlighted over SPC's current SBCAPE and Day 1 Outlook.

CAPE values won't reach intense levels today, possibly in the 1000 J/KG range. The main component today will be the forcing from the converging airmasses. Expect to see storm redevelopment later this afternoon almost in the same spot the original MCS developed early this morning.

That being said, I don't feel like this is an ideal setup for us here in Central Ohio to get storms. We'll be right on the border of the worst, so expect Cincinnati to see more action than Columbus.

I'll update later if storms begin developing further east than expected.
