Oklahoma Supercell – August 17, 2009

081709bA great August chase day!  I usually spend the summer months just hoping for storms that will produce good lightning ops… but on Monday (17th), we got lucky with not only nice lightning – but good supercell structure to go along with it.  The atmosphere was extremely unstable with surface based CAPE in excess of 5000 j/kg over parts of northwest Oklahoma.  Mid level flow wasn’t the greatest….but was about 25 knots.  The two combined to produce several severe storms – some of which produced significant severe weather just northwest of Okarche.  The first storm we took a look at was just northwest of Watonga.  This storm had some decent structure for a bit and had a rotating wall cloud that opened eyes.  When this storm was undercut by outflow which spread to the southeast…. another storm formed just southeast of Watonga.  This storm quickly became severe and exhibited supercell characteristics right from the start.  It didn’t move very quickly… lazy would be the best way to put it… as it headed southeast around 5 mph.  Before it made it into Kingfisher or Canadian Counties… it started getting strong development on it’s southwest flank… which caused it to drift southwestward toward Geary.  The end result was us watching a severe storm about 10 miles from where we first started our chase.  The storm itself was incredible!  The supercell structure that it displayed was some of the best you could ever expect to see anytime of the year.  And the lightning that it produced was extremely impressive and fairly easy to photograph.   Below is a radar image of the storm when it looked it’s best visually.  Also… an image from about the same time.  This supercell stayed just west of Okarche and we only received 0.17 inches of rain from it.  Later that night (18th) and into the morning hours… another 1.89 inches of rain fell which set a record for the date.  Yes, things continue interesting around here – and as I type… a line of severe storms is moving east through the western part of the state.
