Comments on: Mircroburst http://www.neptunuslex.com/2007/01/20/mircroburst/ The unbearable lightness of Lex. Enjoy!

I'm currently working on my IFR ticket (helicopter) and GA training takes microbursts very seriously. As far as the weather briefs go, www.aviationweather.gov has pretty much everything that the military gets (unless things have changed recently) with the exception of fewer PIREPS. The FAA requires you to get a weather brief, but does not require it to be from DUATS or the FSS (where that fact that you got a brief is documented). That being said, it's up to the pilot to use the tools. Since I'm flying in the Phoenix area we generally have clear indications of microburst conditions so it's pretty easy to avoid the situation. A helicopter is going to respond a little differently to the windshear, but I have no interest in being swatted out of the air like a bug.

“The thunderstorm event of Dec. 29, 2006, that spread almost the entire length of Texas was one of the most unusual weather circumstances we’ve seen in 20 years,” said Tim Wagner, a spokesman. More than 80 flights were diverted from D/FW that day.

It was an MCS (and a fundamental misunderstanding of its nature) that had a whole lot to do with an MD-80 finding its way into the Arkansas River a while back…

…THE POTENTIAL FOR NEAR SURFACE-BASED STORMS WITH DAMAGING WINDS SHOULD INCREASE AS SURFACE LOW DEVELOPS EWD AND FORCING ACROSS THE WARM SECTOR AND ALONG THE WARM FRONT INTENSIFIES
FROM THE RED RIVER SWD ACROSS TX. THIS POTENTIAL APPEARS MOST LIKELY TO UNFOLD THROUGH EARLY FRIDAY MORNING.

They shouldn’t let Mr. Wagner discuss the weather…
