Historic Multi Day Tornado Outbreak. 4/25-28/2011

[kayci]

SO! Can any of you awesome weather mets/pros/mods/etc. people tell me what's in store for galveston county tonight??? I'm getting mixed messages from neighbors.

Both Tornado Watches will be replaced within the hour. New MCD extends into the Houston metro area....if the circled region is accurate, the new watch *may* include Harris county. That remains to be seen however. Here is the link.

The new watch coming out will be for the same region except it will exclude Austin and Waller counties.

A strong cap remains in place across the southern sections of the region this evening and with the combination of losing daytime heating plus the majority of the energy passing to our north, I do not see a severe threat for the Houston area. It might have been a different story if the clouds had mixed out and we saw greater daytime heating.

Unfortunately it looks like Houston county will be under the gun again this evening as numerous tornadic supercells are going to be moving in from the northwest over the next 30min to 1-hr. Storms could get into our northwest counties in the next couple of hours if they hold together or can send out a strong enough outflow boundary to overcome a slightly weaker cap in place across those areas.

I heard that if the storms hold up, they may reach Houston.

Soooo...should I be sleeping with one eye open??

Most likely not. Looking at the current radar NE of Harris county might get something but besides that development out to the west looks minimal to non-existent. As a result you will most likely be in the clear.

Check out the action right now in Alabama.

Is there any relationship with tornado activity and US getting hit by tropical cyclones. This is from 1950-2010.

Let's start with April and May tornado activities.


Two-tailed p value: 0.019
Pearson's R statistic: 0.303
Degrees of Freedom (df): 58

The more active April is, the more likely May will be active as well. This is going to be very concerning.

Now, let's look at spring tornado activity and tropical cyclone landfall.



Two-tailed p value: 0.019
Pearson’s R statistic: 0.303
Degrees of Freedom (df): 58



Two-tailed p value: 0.972
Pearson’s R statistic: 0.005
Degrees of Freedom (df): 58

There is a correlation between Spring tornado activity and tropical cyclones making landfall. However, there is no correlation between Spring tornado activity and major hurricane making landfall on America.

what a heart-wrenching day of storms http://tinyurl.com/3ly6jz6

What a historic Tornado Outbreak. It appears this multi day event has come very close to rivaling the infamous 1974 Super Outbreak. As the investigations/surveys continue, my thoughts are with those that are suffering and with those many (over 300+ so far) that have lost their lives.

The amount of tornado warnings were unreal yesterday. I watched this unfold yesterday on ChaserTV.com, Facebook, and Twitter, as well as numerous NWS websites and SPC. There was no doubt this would be an extreme event. My heart goes out to all those effected by a historic weather event. I am sure the death toll will rise. I am also sure we will hear many incredible survivor stories over the next few weeks.

Sadly, AP reporting death toll has surpassed the 1974 Super Outbreak.
