1240pm - severe storms most likely to affect OKC metro area after 8pm. #okwx
Speaking of north central Oklahoma.
Blackwell is one of the most tornado aware small towns in Oklahoma.
For many years every school has had a large underground storm shelter….
They have over lapping storm siren coverage. They have had a good network of storm spotters and a dedicated channel for local cable coverage?
The vast majority of people have a basement or access to a shelter.
Current showers/storms will move through without much fanfare. Western OK is starting to bake again and some CU is starting to go up. Impacts to the metro area will depend which storms get their act together and can be sustained.
First of the day...
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 081921Z - 082115Z
PROBABILITY OF WATCH ISSUANCE...95 PERCENT
SUMMARY...NRN END OF ELEVATED TSTM BAND HAS INTENSIFIED ALONG THE
OK/KS BORDER AND WILL POSE A NEAR-TERM RISK FOR LARGE HAIL AND
STRONG WIND GUSTS. ADDITIONAL STORMS WILL LIKELY FORM ALONG THE
QUASI-STATIONARY FRONT AND DRYLINE BY EARLY EVENING WITH THE TORNADO
RISK INCREASING ESPECIALLY AFTER 00Z.
DISCUSSION...LEAD MID-LEVEL SHORTWAVE IMPULSE THAT HAS PRODUCED
SCATTERED ELEVATED TSTMS WITH LITTLE RAINFALL BUT ABUNDANT CLOUD
COVERAGE HAS SLOWED SURFACE-BASED DESTABILIZATION FROM CNTRL OK SWD.
NRN PORTION OF THIS CONVECTION HAS RECENTLY INTENSIFIED ALONG THE
KS/OK BORDER AREA AND WILL PROGRESS NEWD WHERE SURFACE TEMPERATURES
HAVE WARMED INTO THE LOWER 80S. EVEN THOUGH MODIFIED 18Z TOP RAOB
SUGGESTS MLCIN REMAINS ROBUST...THE PRESENCE OF THIS ELEVATED
CLUSTER AMIDST A VERY UNSTABLE AIR MASS AND STRONG DEEP-LAYER SHEAR
COULD SUPPORT A SWATH OF LARGE HAIL AND STRONG WINDS THROUGH LATE
AFTERNOON.
ADDITIONAL STORMS WILL PROBABLY FORM UPSTREAM OVER NW OK WITHIN THE
NARROW CORRIDOR OF INTENSE HEATING NEAR THE DRYLINE AS HIGH-BASED
CONVECTION OVER THE TX PANHANDLE OVERSPREADS IT LATER. LARGE HAIL
/SOME SIGNIFICANT/ WOULD BE THE PRIMARY INITIAL HAZARD. AS THE LLJ
STRENGTHENS THIS EVENING...THE RISK FOR TORNADOES /A FEW STRONG/
WILL INCREASE AS WELL.

Recent image of the visible satellite with the dryline drawn on. Mesonet images are for dewpoints and also solar radiation - where the sun is out. Currently out in most area ahead of the dryline all the way through SW OK - which there is still a lot of cloud cover but well ahead of the dryline some.
This cloud deck is holding temperatures pretty well.
I am almost ready to go out on a limb and say garden variety storms for SW to C OK, and keep most serious business activity north. The only thing that leaves caution is the fact the atmosphere is very unstable over the entire area which could make some storms pack a decent punch if held together long enough.

Sorry for off topic, but you guys need widescreens! For Pete's sake, you could have about 20x the desktop space with a few 2550x1600 (1600p) displays!
Once again - thank you for the coverage you provide here Venture. I always follow the threads (may not understand all of the terminology) and my friends now think I am a weather guru of some sort!
