* AT 238 PM CDT...NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATED

VERY STRONG ROTATION ASSOCIATED WITH A CONFIRMED TORNADO 3 MILES

SOUTH OF GRAY. THIS TORNADIC STORM WAS MOVING NORTHEAST AT 40 MPH.

LARGE DESTRUCTIVE HAIL UP TO BASEBALL SIZE IS ALSO EXPECTED WITH

THIS STORM.

* LOCATIONS IMPACTED INCLUDE...

GRAY...BURDETT...ROZEL...SANFORD AND ASH VALLEY.

A LONG TRACK TORNADO IS IN PROGRESS. LOCATIONS FROM HANSTON

TO BURDETT ARE IN PARTICULARLY HIGH IMMEDIATE DANGER!

New Day 1 is out:

http://kamala.cod.edu/spc/latest.acus01.KWNS.html

LATEST RUC MODEL GUIDANCE SUGGESTS THAT COOLING ALOFT

WITH THE UPPER TROUGH MAY BE MORE ADVANCED THAT PREVIOUSLY FORECAST

WITH 500 MB TEMPS OF -12 TO -13 C TO THE DRYLINE BY 00Z. THIS WILL

ONLY HELP TO INCREASE UPDRAFT ACCELERATION IN AN ALREADY VOLATILE

SETUP. AT THIS TIME...IT APPEARS THE MOST LIKELY CORRIDOR FOR

VIOLENT TORNADOES WILL BE FROM NW OK ACROSS NRN OK INTO CNTRL AND

S-CNTRL KS. VERY LARGE HAIL WILL ALSO OCCUR. WITH ONGOING CELLS OVER

CNTRL KS...THE LOCATION OF OUTFLOW BOUNDARIES MAY ALSO PLAY A KEY

ROLE IN TORNADOGENESIS AS SUPERCELLS INTERACT WITH THEM LATER. SOME

OF THE CITIES WITH THE HIGHEST RISK INCLUDE ENID...PRATT...GREAT

BEND...SALINA...HUTCHINSON...WICHITA.

45% TOR probs now confined to KS

SPC AC 141942

DAY 1 CONVECTIVE OUTLOOK

NWS STORM PREDICTION CENTER NORMAN OK

0242 PM CDT SAT APR 14 2012

VALID 142000Z - 151200Z

...THERE IS A HIGH RISK OF SVR TSTMS FOR CNTRL AND ERN KS AND

NEB...AND MUCH OF NRN OK...

...THERE IS A MDT RISK OF SVR TSTMS FROM CNTRL OK NWD ACROSS

KS...NEB...SWRN IA AND NWRN MO...

...THERE IS A SLGT RISK OF SVR TSTMS FROM N TX INTO SERN SD AND SRN

MN...

..OK/KS

VISIBLE SATELLITE IMAGERY SHOWS THICK STRATUS RELATED TO THE

ADVECTION OF MID 60S F BOUNDARY LAYER DEWPOINTS FROM NRN TX INTO

CNTRL OK AND CNTRL KS...WITH SSELY SURFACE WINDS GUSTING OVER 30

MPH. A SPECIAL 17Z OUN SOUNDING SHOWS THE PRESENCE OF A WARM LAYER

NEAR 650 MB...WITH RELATIVELY COOL...BUT MOIST...PROFILES IN THE

LOWEST 3 KM. LATEST RUC FORECAST SOUNDINGS INDICATES CAPPING

INCREASING AFTER 21Z OVER PORTIONS OF SRN AND ERN OK. THUS...THE

THREAT APPEARS MORE CONDITIONAL THERE...BUT VERY CLOSE TO THE EDGE

OF THE ONGOING HIGH RISK AREA. THUS...NO CHANGES WILL BE MADE.

TO THE W...CLEARING WAS TAKING PLACE ALONG AND E OF THE DRYLINE FROM

SW KS INTO THE OK AND TX PANHANDLES AND WRN OK. SURFACE OBSERVATIONS

SHOWED TEMPERATURES RISING INTO THE MID TO UPPER 70S OVER WRN

OK...AND AT OR ABOVE 80 F IN THE PANHANDLES. AS A RESULT...THE

ATMOSPHERE HAS BECOME UNCAPPED IN THESE AREAS. INDEED...SEVERE

STORMS WERE ALREADY ONGOING OVER WRN KS INTO FAR NW OK ALONG THE

DRYLINE...WITH TOWERING CU FARTHER S.

WAVES OF STORMS SHOULD CONTINUE TO FORM ON THE DRYLINE...WHERE

CONVERGENCE IS INCREASING AS SURFACE WINDS VEER OVER THE PANHANDLES.

THESE STORMS SHOULD BECOME PROGRESSIVELY MORE SEVERE...AS LOW LEVEL

SHEAR CONTINUES TO INCREASE ACROSS THE WARM SECTOR. FORECAST

SOUNDINGS SUGGEST THAT UPPER 70S TO LOWER 80S TEMPERATURES WILL BE

NEEDED TO INITIATE STORMS.

MEANWHILE...LATEST RUC MODEL GUIDANCE SUGGESTS THAT COOLING ALOFT

WITH THE UPPER TROUGH MAY BE MORE ADVANCED THAT PREVIOUSLY FORECAST

WITH 500 MB TEMPS OF -12 TO -13 C TO THE DRYLINE BY 00Z. THIS WILL

ONLY HELP TO INCREASE UPDRAFT ACCELERATION IN AN ALREADY VOLATILE

SETUP. AT THIS TIME...IT APPEARS THE MOST LIKELY CORRIDOR FOR

VIOLENT TORNADOES WILL BE FROM NW OK ACROSS NRN OK INTO CNTRL AND

S-CNTRL KS. VERY LARGE HAIL WILL ALSO OCCUR. WITH ONGOING CELLS OVER

CNTRL KS...THE LOCATION OF OUTFLOW BOUNDARIES MAY ALSO PLAY A KEY

ROLE IN TORNADOGENESIS AS SUPERCELLS INTERACT WITH THEM LATER. SOME

OF THE CITIES WITH THE HIGHEST RISK INCLUDE ENID...PRATT...GREAT

BEND...SALINA...HUTCHINSON...WICHITA.

..NRN KS/NEB

LARGE SUPERCELLS ARE ONGOING ACROSS NRN KS...WITH STRONG

MESOCYCLONES NOTED ON RADAR AND PROBABLY TORNADOES. THESE CELLS WILL

CONTINUE TO TREK NEWD INTO NEB WHERE SHEAR REMAINS STRONG AND

INSTABILITY IS SUFFICIENT WITH RELATIVELY COOL TEMPERATURES. IN

ADDITION TO A TORNADO THREAT...SOME OF THESE HP CELLS MAY EVENTUALLY

BOW WITH DAMAGING WIND THREAT AS WELL.

ANOTHER LIKELY AREA OF SUPERCELL TORNADO DEVELOPMENT WILL BE FROM

NWRN KS INTO WRN AND CNTRL NEB. VISIBLE IMAGERY SHOWS A LARGE CU

FIELD...W OF THE ONGOING KS ACTIVITY...AND E OF THE DRYLINE. BACKED

SURFACE FLOW OVER NEB...ALONG WITH CONTINUED HEATING AND COOLING

ALOFT SHOULD PROVE FAVORABLE FOR A DEVELOPING TORNADO AND LARGE HAIL

THREAT. STRONG TORNADOES WILL REMAIN POSSIBLE AREA-WIDE.

Hey guys!

Not to try and derail the thread here, as there are obviously bigger things to discuss, but looking at Chaser TV after getting home there are a lot of chasers to choose from...is there a particular chaser/cam that anyone here could recommend?

Thanks!
