thunderman Posted July 8, 2012 Share Posted July 8, 2012 Gotta admit, not really sure what's keeping these storms from going up. Great cape, decent (and increasing) shear... Shear is marginal at best ... sfc - 6km under 30kts. Also, low level wind fields aren't overly great either ... which helps to put a lid on new cells forming and sustaining themselves along gust fronts. Mid level lapse rates are marginal. Lastly, PWATS are very high which means you have a lot of mass to lift in the updrafts today. Without good shear/SR winds to vacate that mass, updrafts will struggle.

Kmlwx Posted July 8, 2012 Share Posted July 8, 2012 winds dont look svr on radar.. plus it's not moving the shape of the box Re: the polygon warning boxes - there have been some weird shaped ones in the days since 6/29 - there was one the other day that was way bigger than it needed to be. I seem to remember LWX canceling a huge chunk that hadn't seen so much as a drop of rain within 10 or 15 minutes of the issuance. Link to comment Share on other sites More sharing options...
yoda Posted July 8, 2012 Share Posted July 8, 2012 Hail up to the size of quarters? The tops are 13,000 ft... I aa confused as to why that cell is warned... I am waiting hopefully for the one behind it to the west Link to comment Share on other sites More sharing options...
Ian Posted July 8, 2012 Share Posted July 8, 2012 Hail up to the size of quarters? The tops are 13,000 ft... for tops it's too close to the radar if you're looking at lwx Link to comment Share on other sites More sharing options...

mattie g Posted July 8, 2012 Share Posted July 8, 2012 Seems like its taking its sweet time moving too... hoping that storm can get me in Southern fairfax later.. as Ian said above, storms seem to have a more easterly component of late That big cell just south of Leesburg looks like it's got its eye on us, yoda.

thunderman Posted July 8, 2012 Share Posted July 8, 2012 winds dont look svr on radar.. plus it's not moving the shape of the box Not a 100% sure, but I guess they did it because reflectivites aloft jumped again right after the warning was dropped. Between that and what they are seeing out their window, they must fell like it will be become severe again. Link to comment Share on other sites More sharing options...
