Chase Summary of 16 November 96 by Craig A. Green N5WEH Numeric modeling showed some promise for a seasons end chase on Saturday, November 16th and I anxiously awaited the SWODY1 early Saturday morning. Finding a moderate risk for most of Oklahoma, I prepared to depart at about 11:00 AM. After running a few errands, I logged in for the ETA modeling and some last minute data. Oh no! Eta models were not available. I grabbed a surface analysis, moisture advection, 300 mb streamlines, and my camera and picked up my partner Bill Brockman. Crossing the OK border north on US 81 headed for the Lawton area, we heard the SPC box for SW OK a little after 1300. Gulf advection was obscuring the sky so we began monitoring NWS and their 147.045 liaison frequency. Knowing the front was west of us we began looking . Heading north on OK 58 from Medicine Park, we began hearing severe thunderstorms warnings SW of us near the Wichita Mts. Wildlife Refuge. We could already see a rapidly growing raincore to our SW. As we paused, NWS issued a tornado warning for SE Caddo Co. If we hurried we could cut the corner across to OK 19 and go east to get on the upshear side of the storm. Hearing of a lowering with slow rotation on the rear flank of the storm, we drove south and then east through heavy rain which subsided at Apache. We parked and faced SW at 1545 PM, observing an approaching intense rain shaft and when it arrived with intermittent 1 inch hail, we began driving east on OK 19 toward Cyril. Approximately 3 to 4 miles east of Apache, several transformer explosions (4 to 5) were seen directly north of us. A wall cloud with 5 or 6 fingery filaments had spun up a weak tornado with no visible condensation funnel ! Cloud tags and inflow were visibly moving up into the updraft base. Off to the SE was an inflow band connected to the upshear side of the storm with the wall cloud. No further transformer explosions or debris clouds on the ground were observed as we headed through Cyril and towards Cement on US 277. We kept taping the wall cloud as it moved off to the NE at a reported 45 MPH. This storm and another that had formed SW later merged into a long squall with some impressive shelf clouds and CG. We turned south on US 81 from Chickasha and caught another gustfront from a large squall cell between Geronimo and Duncan before we headed back to Dallas. Not bad for mid-November.
