Do We Need More Rain After Last Week?

One quick update first from the National Weather Service in Cleveland.

...The short answer to that question is NO. The long answer to it is YES.

Here is a graph showing our actual rainfall versus the normal rainfall for all of Ohio over the last 2 weeks.

No wonder why the grass is so much greener recently.  90% Northeastern Ohio is above normal since May 1st.

Now, look at the map showing actual rainfall versus the normal rainfall over the last month.

A totally different picture.  Aside from some select areas where severe storms developed last week, more than 50% of Northeastern Ohio is still slightly below normal over the long haul.

Coming up Monday and Tuesday, we'll talk about the MUCKELHEADS!

"Today we chased a mesocyclone from the Western panhandle of Oklahoma into Texas, got some great footage of initial rotation and lightning, this storm did produce 1 tornado but it was on our southwest side and it was rain-wrapped so we couldn’t see it. It eventually weakened but left us with some great photo opportunities and footage, will post those pictures tomorrow, however I did want to post my first official footage clip, this was one of the first tornadoes that touched down on Monday just south of Wakita before all the chaos ensued"

Odds of Getting Struck by Lightning and other Weather

After a rough weather week and a much quieter weekend ahead, let's have some fun looking at weather odds.

Many people are deathly afraid of severe weather.  Are the chances of getting killed by severe storms as high as what most people believe?  According to the bookofodds.com, the chances of being killed by a tornado are:

1 in 4, 513,000

For comparison, the chances of dying from a fall off a cliff is:

1 in 4,101,000

The bookofodds.com correctly points out these facts about the deadliest tornado on record:

"The tornado with the highest death count was the 1925 Tri-State Tornado, which ravaged a path a mile wide and 219 miles across through Missouri, Illinois,and Indiana. The speed was 60 miles per hour—twice the forward speed of the average tornado. Although the Tri-State Tornado lacked the classic funnel cloud, and was therefore virtually invisible, the damage was catastrophic: nearly 2,000 people were injured, property losses totaled more than $16 million, and 689 people died."

The Deadliest Weather of the Decade; Top ten states/chances of getting killed by weather. (1999 to 2008). A word of caution: A distaster like Hurricane Katrina will significantly skew these chances higher for the state effected.

1. Louisiana 1 in 49,330
2 Mississippi 1 in 112,700
3 Alaska 1 in 116,900
4 Wyoming 1 in 173,800
5 Missouri 1 in 182,900
6 Oklahoma 1 in 240,500
7 Arkansas 1 in 287,800
8 Kansas 1 in 290,300
9 Illinois 1 in 303,900
10 Utah 1 in 337,700

The odds of getting by lightning: 1 in 835,500

The odds of getting killed by hail: 1 in 734,400,000

The odds of a meteor landing on your house: 1 in 182,138,880,000,000

More Severe Possible Today

A few storms earlier today along the warm front.   They moved away very fast.

I rarely go into the science into weather forecasting mainly because it bores most people.  People want an accurate forecast and could care less where you get it or how you come up with it.

Since we've had several severe weather events over the last week, I figure that this is good time to go over some of the parameters that are analyzed in determining whether or not severe weather is possible.

Today, another two pronged system is developing in the middle of the US early Thursday morning.  The first wave is along the warm front which pushes through Ohio later on this morning/early afternoon.  Temperatures surge into the 70s after the warm front goes north.

After that, the cold front approaches with plenty of energy with it.

The components for today's severe weather are these:

* Humid air
* Warm temperatures & sunshine
* Strong cold front/lots of lift
* Changing wind direction from the ground up to 18,000 feet

How Massive is the Oil Spill? Tornado Video

A new image from NASA's recent earth imagery section shows the massive extent of the Oil Spill.  The legend at the top shows a 25 kilometer length (15 miles).  That is roughly 120 miles long!

Oklahoma City Tornadoes - May 10th

Monday evening just outside of Oklahoma City, Oklahoma, a tornado outbreak began killing 5 and injuring dozens of others.

Here is a photo that my sister's neighbor took as one of these approached the area.  

A brandnew photo of my sister and her kids in the neighbor's storm shelter.  The shelter is approximitely 4 feet by 10 feet.

The National Weather Service office in Norman, Oklahoma created this preliminary map of the tornadoes after the event.  More information about each tornado will be released once severe weather surveyers inspect the damage to determine the intensity of each tornado.

Friday's Severe Weather Recap

Friday marked the first time Cleveland, Akron and Canton (The NE Ohio metro area) was under a TORNADO WATCH in roughly 4 years.  The setup for severe weather was tremendous yet no TORNADOES. 

(ALL GRAPHICS COURTESY OF THE STORM PREDICTION CENTER AND THE NATIONAL WEATHER SERVICE OFFICE IN CLEVELAND, OHIO)

The Storm Prediction Center put northern Ohio under a MODERATE RISK early in the morning.  Northern Ohio is rarely under a MODERATE RISK--maybe once every two years--so the experts believed that this could have been deadly.

The Tornado Watch was issued at 3:50PM then the extension through 11PM
