Central Ohio

Posted by: Buckey2745, 08:03 PM GMT del 01 Maggio 2012

Not long after I made my last post the NWS issued a Tornado Watch for the southwestern portion of Ohio. While this wasn't a total shock, it was interesting to see something that went from a low risk severe day go to a Tornado Watch being issued.

Here's the watch area not including the Columbus area:

A warm front is lifting through our area with storms firing along the boundry. What's noticeable is an area of partly cloudy skies to the south of I-70 which should help feed this instability.

Map highlights area of greatest instability lifting slowly to the north.

There's a sharp cutoff of instability that coincides with the break in the clouds. Most of Kentucky has moderate instability while areas north of I-70 has almost none.

So far there's been little spin in the upper atmosphere over Kentucky where the greatest instabity is. However it appears decent shear sits over Indiana and will move east, while the greatest instability moves northeast. That'll put southern Ohio in the crosshairs.

It'll be interesting to see how quickly the atmosphere recovers after these debris clouds move out later. We have a small window for any supercells, but bowing segments will be probable overnight. Right now I feel like the worst won't make it much further north than Cincinnati. We'll see. I'll post more as storms develop.

Quiet April

Posted by: Buckey2745, 02:51 PM GMT del 01 Maggio 2012

I've gone almost a month without posting because putting filler in the blog seemed kind of pointless. April was too quiet for any type of update. In all we had one Severe Thunderstorm Warning for this hail storm on the morning on April 26th:...and a Severe Thunderstorm Watch yesterday, our last day of the month, for a complex of storms that never panned out. That was it.But when you look closer and the quiet month of April you'll notice the temperature difference co...

Marching Out

Posted by: Buckey2745, 04:16 PM GMT del 04 Aprile 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 compi...

April 1st: Another Slight Chance of Storms

Posted by: Buckey2745, 05:27 PM GMT del 01 Aprile 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 ...

March 30th: Slight Risk of Evening Storms

Posted by: Buckey2745, 03:22 PM GMT del 30 Marzo 2012

Our active March continues with our latest risk of severe weather this evening. A deeping low pressure is ejecting out of the Plains and in to the Ohio Valley this evening. We've already seen some cold shower activity out ahead of the system this morning, bringing about a tenth of an inch of rain. What this is going to do is leave a fairly moist airmass in place for this afternoon when clouds will break up a bit ahead of the storm and allow decent daytime heating to...
