May Weather Discussion.

Spent the weekend in Onalaska, TX/Livingston to fix mom & dad's A/C... came home to find my big oak tree down in my front yard (Texas city). What happened Saturday???? Left at 8 a.m. Saturday morning and it was just drizzling... came back today (Sunday) and my Oak tree was down. Neighbor said we only had light rains but a little wind. pooooor oak tree. breaking out the chainsaw.

My guess, kayci, is that a severe thunderstorm produced very strong wind gusts that were again powerful enough to uproot your large oak tree. Wxdata, could we go back in time with the radar as far as rewind it beginning from yesterday morning to this evening?

I did find this-

1235 PM FUNNEL CLOUD LEAGUE CITY 29.49N 95.11W
05/15/2010 GALVESTON TX EMERGENCY MNGR

It may be that the associated storm was strong enough to take down a tree.

[kayci]

Wow! Thanks, that's interesting!

[srainhoutx]

Looks like the sea breeze is heading N. Appears to be a weak boundary to our N as well. Perhaps enough of a 'trigger' to fire off some showers/storms this afternoon. Keeping eye to our NW as well with yet another meso heading ESE.

[wxdata]

NAM is showing no cap by 4pm, however severe indices are marginal for the afternoon (according to 12z NAM.)

[wxdata]

At 12:30 seabreeze readily apparent on satellite:

I would just be happy for some more rain, can see towering CB's to my NW, with planty of daytime heating and a weakening cap, I wonder how active it may get?

Can someone please tell me what SCATTERED TSRA DEVELOPMENT means? I was just looking at the forecast for my area on the NOAA website and didn't know what that meant. Thank you!

[srainhoutx]

Folks in the Porter/Kingwood areas need to keep an eye out!

Better chance of getting wet than "isolated", less chance than "widespread"

Thank you...to all the members in the path of these severe storms please stay safe!
