• After witnessing the continued decrease of involvement in the SpotterNetwork staff in serving SN members with troubleshooting issues recently, I have unilaterally decided to terminate the relationship between SpotterNetwork's support and Stormtrack. I have witnessed multiple users unable to receive support weeks after initiating help threads on the forum. I find this lack of response from SpotterNetwork officials disappointing and a failure to hold up their end of the agreement that was made years ago, before I took over management of this site. In my opinion, having Stormtrack users sit and wait for so long to receive help on SpotterNetwork issues on the Stormtrack forums reflects poorly not only on SpotterNetwork, but on Stormtrack and (by association) me as well. Since the issue has not been satisfactorily addressed, I no longer wish for the Stormtrack forum to be associated with SpotterNetwork.

    I apologize to those who continue to have issues with the service and continue to see their issues left unaddressed. Please understand that the connection between ST and SN was put in place long before I had any say over it. But now that I am the "captain of this ship," it is within my right (nay, duty) to make adjustments as I see necessary. Ending this relationship is such an adjustment.

    For those who continue to need help, I recommend navigating a web browswer to SpotterNetwork's About page, and seeking the individuals listed on that page for all further inquiries about SpotterNetwork.

    From this moment forward, the SpotterNetwork sub-forum has been hidden/deleted and there will be no assurance that any SpotterNetwork issues brought up in any of Stormtrack's other sub-forums will be addressed. Do not rely on Stormtrack for help with SpotterNetwork issues.

    Sincerely, Jeff D.

I just observed a heat burst a few minutes ago at our house about 15 miles east of Norman. This started about 10:40 pm with some gusts out of the southeast. The temperature maxed out at 85.0 deg F at 10:51 to 11:01 pm before slowly falling.

Looks like the Norman mesonet got pinged a bit too:

at about 10:30 pm, reaching about 84 or so with dewpoints falling off precipitously.

Radar during the event (winds had died down by this time):

Sounding 4 hours ago (warm temperatures from earlier daytime high of 86F):

I wonder why this pattern is so particularly conducive to heatbursts... I hear they happened last night near Waurika.

I kept waiting for the good winds here in south Norman, but nothing exciting. Certainly could feel the warmup as well as the drier air. This beats a tornado any day.

Three nights in a row with recorded heat bursts...quite the treat!

Looks like Shawnee recorded an 88 degree reading just downstream from Tim. Freedom experienced a heat burst closer to Waurika's early Sat. morning. The Mesonet site recorded a 91.4 degree temp. and 38.9 degree dew point reading shortly after 4am. Wish I could have experienced either event.

I did my M.S. research on heat bursts... June and July are actually prime time for heat bursts to happen due to a couple of things:

- It's MCS season, and
- It's getting hot.

Heat bursts happen with dissipating high based convection after the nocturnal inversion has begin to develop. The thermodynamics were perfect for heat bursts last week because there was a good, dry EML up to a high cloud base - especially on Norman's heat burst evening. This just accelerates the parcels descending from the dissipating convection and helps erode the nocturnal inversion, resulting in the rapid warming and drying.

Heat bursts are really cool (no pun intended!), and quite interesting - although I don't necessarily agree with Rob's comment! Haha! :D
