SPC AC 130602

DAY 2 CONVECTIVE OUTLOOK RESENT 1

NWS STORM PREDICTION CENTER NORMAN OK

0102 AM CDT FRI APR 13 2012

VALID 141200Z - 151200Z

...THERE IS A HIGH RISK OF SVR TSTMS ACROSS PARTS OF OK AND KS...

...THERE IS A MDT RISK OF SVR TSTMS ACROSS PARTS OF NW TX...CNTRL

AND WRN OK...CNTRL AND ERN KS...SE NEB...NW MO AND FAR SW IA...

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE MID-MO

VALLEY...UPPER MS VALLEY...SRN PLAINS AND CNTRL PLAINS...

TORNADO OUTBREAK LIKELY ACROSS THE SRN AND CNTRL PLAINS NWD INTO THE

MID-MO VALLEY FROM SATURDAY AFTERNOON THROUGH SATURDAY NIGHT

...SRN AND CNTRL PLAINS...

AN IMPRESSIVE UPPER-LEVEL LOW WILL MOVE EWD ACROSS FOUR CORNERS

REGION SATURDAY AS A POWERFUL 90 TO 110 KT MID-LEVEL JET EJECTS NEWD

INTO THE SRN AND CNTRL PLAINS. AHEAD OF THE SYSTEM...A CORRIDOR OF

MODERATE TO STRONG INSTABILITY IS FORECAST ACROSS ECNTRL KS...CNTRL

OK INTO NW TX. THIS COMBINED WITH STEEP MID-LEVEL LAPSE RATES AND

STRONG LOW-LEVEL SHEAR WILL BE VERY FAVORABLE FOR SEVERE STORMS AND

A TORNADO OUTBREAK WILL BE LIKELY ACROSS THE SRN AND CNTRL PLAINS

FROM LATE SATURDAY AFTERNOON LASTING THROUGH THE EVENING AND INTO

THE OVERNIGHT PERIOD.

NAM AND NAMKF FORECAST SOUNDINGS AT 00Z SATURDAY EVENING FROM SALINA

KS SWD TO AROUND OKLAHOMA CITY SHOW MLCAPE VALUES FROM 2000 TO 3000

J/KG WITH 0-6 KM SHEAR IN THE 60 TO 75 KT RANGE. IN

ADDITION...HODOGRAPHS ARE LARGE AND LOOPED WITH 0-1 KM SHEAR VALUES

IN THE 30 TO 40 KT RANGE. THIS ENVIRONMENT SHOULD BE VERY FAVORABLE

FOR SUPERCELLS AND TORNADOES. 0-3 KM STORM RELATIVE HELICITIES ARE

FORECAST TO BE AROUND 400 M2/S2 WHICH IS IDEAL FOR STRONG TORNADOES

AND A TORNADO OUTBREAK APPEARS LIKELY. THE GREATEST THREAT FOR

SIGNIFICANT TORNADOES SHOULD EXIST SATURDAY EVENING FROM SALINA SWD

TO OKLAHOMA CITY. 700 TO 500 MB LAPSE RATES AROUND 7.5 C/KM WILL

ALSO BE FAVORABLE FOR LARGE HAIL AND HAIL GREATER THAN 2 INCHES WILL

BE POSSIBLE THE MORE INTENSE SUPERCELLS. A WIND DAMAGE THREAT WILL

ALSO EXIST DUE TO THE EXPECTED INTENSE NATURE OF THE STORMS.

THE MAIN CONCERN FOR THIS FORECAST IS CONVECTIVE COVERAGE. MANY OF

THE MODELS DO NOT DEVELOP NUMEROUS THUNDERSTORMS ALONG THE DRYLINE.

IN SPITE OF THIS...THE MODELS DIMINISH THE CAP ACROSS THE SRN AND

CNTRL PLAINS LATE SATURDAY AFTERNOON SO THIS BRINGS THE MODELS INTO

QUESTION. IN ADDITION...THE MODELS DRIVE A BAND OF LARGE-SCALE

ASCENT ACROSS CNTRL KS DURING THE EARLY EVENING SUGGESTING MANY

STORMS SHOULD INITIATE WITH STORMS INITIATING SWD WITH TIME EARLY

SATURDAY EVENING AS THE LOW-LEVEL JET STRENGTHENS. THESE FACTORS

COMBINED WITH SFC DEWPOINTS IN THE LOWER TO MID 60S F AND VERY

FAVORABLE LOW-LEVEL SHEAR PROFILES SHOULD PRODUCE AND ENVIRONMENT

FAVORABLE FOR A TORNADO OUTBREAK. AFTER COLLABORATION WITH WFOS

WICHITA...NORMAN...TOPEKA...TULSA AND DODGE CITY...A HIGH RISK WILL

BE ISSUED DUE TO THE POTENTIAL FOR A HIGH-END LIFE THREATENING EVENT

ACROSS THE SRN AND CNTRL PLAINS.

...MID-MO VALLEY/UPPER MS VALLEY...

AN IMPRESSIVE UPPER-LEVEL LOW WILL MOVE ACROSS THE FOUR CORNERS

REGION SATURDAY. AT THE SFC...A LOW SHOULD MOVE ACROSS NEB WITH A

WARM FRONT EXTENDING EWD ACROSS IA. THUNDERSTORMS SHOULD BE ONGOING

ALONG THIS BOUNDARY WITH STORMS EXPANDING NWD INTO THE UPPER MS

VALLEY. SOUTH OF THE BOUNDARY...THE MODELS DEVELOP MODERATE

INSTABILITY WITH A DRYLINE LOCATED IN ECNTRL NEB. THUNDERSTORMS THAT

INITIATE ALONG THE DRYLINE AND EWD ACROSS THE WARM SECTOR WILL

LIKELY HAVE AN ENHANCED SEVERE THREAT. STRONG DEEP LAYER SHEAR AND

ENHANCED LOW-LEVEL SHEAR WILL BE FAVORABLE FOR SUPERCELLS AND

TORNADOES. A FEW STRONG TORNADOES MAY OCCUR WITH THE MORE DOMINANT

SUPERCELLS ESPECIALLY AS THE LOW-LEVEL JET STRENGTHENS SATURDAY

EVENING. ALTHOUGH A TORNADO OUTBREAK WILL BE POSSIBLE ACROSS PARTS

OF THE REGION...THE GREATEST MOISTURE RETURN SHOULD REMAIN FURTHER

TO THE SOUTH SUGGESTING THE HIGHEST TORNADO THREAT SHOULD EXIST

ACROSS SERN NEB...SW IA...NW MO AND ERN KS WHERE A MODERATE RISK IS

LOCATED.

...NW TX/WCNTRL TX...

AN IMPRESSIVE UPPER-LEVEL LOW WILL MOVE EWD ACROSS THE FOUR CORNERS

REGION AND INTO THE HIGH PLAINS SATURDAY EVENING. MODEL FORECASTS

DEVELOP THUNDERSTORMS ALONG A WELL-DEFINED DRYLINE DURING THE

EVENING FROM WRN OK SSWWD ACROSS NW TX INTO WCNTRL TX. FORECAST

SOUNDINGS SATURDAY EVENING ALONG THIS CORRIDOR SHOW MODERATE

INSTABILITY...STRONG DEEP LAYER SHEAR AND STEEP MID-LEVEL LAPSE

RATES WHICH SHOULD BE FAVORABLE FOR SUPERCELLS WITH LARGE HAIL.

SUPERCELLS SHOULD BE CAPABLE OF PRODUCING 2 INCH OR GREATER HAIL DUE

TO THE THERMODYNAMIC PROFILE. STRENGTHENING LOW-LEVEL SHEAR DURING

THE EVENING SHOULD ALSO RESULT IN A TORNADO THREAT AS WELL.

Agreed

It is funny though because growing up on the shoreline getting a good thunderstorm east of New Haven was virtually impossible. I think I only saw hail once in my life. Living up here in the valley it's a different beast. Just depends on where in the region you are.

Agree with your agreement. Up in the NE corner, I've seen a lot of storms tear across western and central CT before fading away - but nothing like happens down along the SE cooast.

I hope you get to chase something good this year!

I know!

I'm not doing baseball this year so I won't have that in the way.

My friend from NH will be coming down the final week of May/first week of June...we've had some pretty good success choosing this period the past 3 years we've done this so hopefully this continues.
