Chase Case 7

I know the date so I am out. All I have to say is I remember watching this event unfold from Arkansas and was wishing I was on the Plains chasing.
 
I've decided to sit in Clarendon,TX. I'd rather be too far north than too far south.
 
I enjoy the lower LCL's and higher SRH around the central Texas panhandle. I like Childress, Texas, where I can use 287 as a springboard wherever development begins.
 
Gonna slip north on Hwy 207 to Silverton, Tx. May jog east to Caprock Canyons State Park after that. I like the lower LCL's in the area and this will be my target for the afternoon. From Pampa to Lubbock and points east and northeast. I should be in Silverton by 19z.

AREAS AFFECTED...WRN NEB...SW SD

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY

DEEPENING CONVECTIVE DEVELOPMENT EVIDENT IN LATEST VISIBLE IMAGERY
APPEARS TO BE OCCURRING IN ZONE OF ENHANCED LOW-LEVEL
CONVERGENCE/WARM ADVECTION TO THE NORTHEAST OF CENTRAL HIGH PLAINS
SURFACE CYCLONE. THIS IS ALSO ALONG AND JUST AHEAD OF SURFACE COLD
FRONT ADVANCING TO THE EAST OF THE WYOMING FRONT RANGE.

DUE TO LIMITED LOW-LEVEL MOISTURE...MIXED LAYER CAPE IS PRESENTLY
VERY WEAK. BUT...MID-LEVEL COOLING IN THE EXIT REGION OF STRONG
SOUTHERLY HIGH LEVEL JET IS CONTRIBUTING TO STEEPENING MID-LEVEL
LAPSE RATES. AND...LIFT SEEMS LIKELY TO OVERCOME WEAK INHIBITION
FOR AT LEAST ISOLATED TO WIDELY SCATTERED DEEP CONVECTIVE
DEVELOPMENT LATE THIS AFTERNOON...POSSIBLY AS EARLY AS 20-21Z.

AS THIS OCCURS...IN STRONGLY SHEARED DEEP LAYER FLOW WITH STRONG
CLOCKWISE CURVED LOW-LEVEL HODOGRAPHS...FORMATION OF SUPERCELLS IS
EXPECTED WITH RISK FOR TORNADOES...IN ADDITION TO LARGE HAIL/
ISOLATED DAMAGING WIND GUSTS. ACTIVITY SEEMS POSSIBLE AS FAR NORTH
AS THE BLACK HILLS AREA...WHERE FAVORABLE OROGRAPHY WILL ENHANCE
FORCING FOR STORMS...DESPITE PRESENCE OF COOLER LESS UNSTABLE
BOUNDARY LAYER.

Expect the next hourly update tomorrow afternoon, and expect three updates tomorrow.
 
Am thinking about positioning a little further south...closer to the deeper moisture
aimed north from the TX Panhandle. I will stop at Scott City KS and re-evaluate later data.
 
Arrived Pampa, like where I am, but may adjust a bit east and north into SW Oklahoma if needed. Line may form just east of here, awaiting further data before I make a decision.
 
Hmm, this last update says get your butt moving! No stopping in Liberal, KS, I need to get NE quick before these storms fire..don't wanna get behind em. I'm headed straight to Minneola, KS
 
Oakley is drying out, with the the best moisture and shear still northeast of me. I'm sort-of committed to the north option, so 20Z will find me in Clayton, and Norton, KS, about 20:20Z. Hopefully things will be starting to pop about then.
