Plus, PDS is specifically notated on watches, you can't miss it.

It is more coincidental that probabilities are high with a PDS. PDS is issued at the discretion of forecasters, usually mass-life taking/threatening situations unfolding.

Where is the dryline positioned at right now? Oklahoma Texas border?

Pretty well out west...but the entire area ahead of the dryline is pretty well primed. It'll help with getting storms going, but not completely required today. It will not move east of the metro until probably Sunday.

Storm is rotating, hail size is increasing. Stay aware. Right now looks like it'll track up towards Grady/Canadian counties.

CONCERNING...TORNADO WATCH 133...

VALID 062027Z - 062230Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 133 CONTINUES.

SUMMARY...TORNADO THREAT CONTINUES FOR WATCH 0133.

DISCUSSION...A WEAKLY-TORNADIC SUPERCELL THUNDERSTORM CONTINUES TO
ORGANIZE OVER SOUTHEAST CADDO COUNTY WITH ADDITIONAL STORMS
DEVELOPING ALONG A CONFLUENCE LINE ACROSS WESTERN OK. VISIBLE
SATELLITE TRENDS SHOW CONVECTION STRUGGLING TO DEVELOP OVER THE
SOUTHERN PORTION OF THE WATCH AREA...BUT STORMS DEVELOPING BETWEEN
MAF AND ABI WILL AFFECT THE SOUTHWEST PORTION OF THE WATCH SOON.
KTLX VWPS AND 19Z OUN SOUNDING INDICATE THE NORTHERN HALF OF THE
WATCH REMAINS UNDER THE INFLUENCE OF THE ENHANCED 900-700 MB FLOW
ASSOCIATED WITH THE STRONG EXITING WAVE TO THE NORTH WHICH HAS
ENLARGED THE LOW-LEVEL HODOGRAPH AND PRODUCED OVER 200 M2/S2 OF 0-3
KM STORM-RELATIVE HELICITY OVER THE WATCH AREA. RELATIVELY WEAK
WINDS IN THE 700-400 MB LAYER MAY BE PREVENTING A STRONGER
ORGANIZATION TO THE SUPERCELL CURRENTLY. HOWEVER...THE KTLX VWP
INDICATES THE LOW-PRESSURE ASSOCIATED WITH THE SUPERCELL OVER
WEST-CENTRAL OKLAHOMA MAY BE LOCALLY-ENHANCING THE SREH THROUGH
BACKING OF THE LOW-LEVEL WINDS...IN ADDITION TO A LARGER-SCALE
BACKING OF THE LOW-LEVEL WINDS CURRENTLY UNDERWAY. THIS WILL ALLOW
FOR CONTINUED STRONG LOW- TO MID-LEVEL ROTATION. ADDITIONALLY...THE
EASTERN EDGE OF THE HIGHER MLCAPE OVER 1500-3000 J/KG NOW EXTENDS TO
EASTERN OKLAHOMA WITH LITTLE INHIBITION REMAINING. THEREFORE THE
TORNADO THREAT IS EXPECTED TO CONTINUE IN THE NEXT FEW HOURS WILL
THIS STORM AS IT APPROACHED THE OKC METRO AREA.
