PROBABILITY OF WATCH ISSUANCE...40 PERCENT

SUMMARY...STORMS DEVELOPING ALONG THE WARM FRONT ACROSS THIS AREA
MAY PRODUCE AN ISOLATED/BRIEF TORNADO. WW MAY BE REQUIRED.

DISCUSSION...LATEST SURFACE ANALYSIS SHOWS A STATIONARY FRONT
EXTENDING FROM CENTRAL NEB SEWD ACROSS SWRN IA/NWRN MO INTO SRN
IL...SEPARATING A WARM/MOIST AIRMASS /TEMPERATURES IN THE 80S AND
DEWPOINTS IN THE MID TO UPPER 60S/ FROM A MUCH COOLER /MID 50S/

MERGING WITH THE FRONT. WITH MODERATE INSTABILITY /1500 TO 3000
J/KG MIXED-LAYER CAPE/ ALONG THE BOUNDARY...A FEW STRONGER CELLS
REMAIN LIKELY -- AIDED BY PRONOUNCED VEERING OF THE WINDS WITH
HEIGHT WITHIN THE LOWEST 3 KM. ALONG WITH HAIL AND/OR LOCALLY
DAMAGING GUSTS WITH A FEW OF THE STRONGEST STORMS...AN
ISOLATED/BRIEF TORNADO WILL ALSO BE POSSIBLE THIS EVENING...BEFORE

FOR POSSIBLE SEVERE TSTM WATCH ISSUANCE.

DISCUSSION...21Z SURFACE ANALYSIS PLACED A LEE SURFACE CYCLONE ALONG
THE E-CNTRL CO/W-CNTRL KS BORDER WITH A DRYLINE ARCING S/SWWD
THROUGH THE ERN TX PANHANDLE TO THE PERMIAN BASIN. HIGH-BASED CU HAS
GROWN IN THE PAST HOUR BOTH ALONG AND W OF THE DRYLINE. WITH VERY
STEEP LAPSE RATES THROUGHOUT THE TROPOSPHERE...THIS CU SHOULD DEEPEN
INTO TSTMS BY 23Z. WITH SLIGHT BACKING OF SURFACE WINDS IN THE KHHF
AND KCDS OBS...MAINTENANCE OF MIDDLE TO UPPER 50S SURFACE DEW POINTS
E OF THE DRYLINE WILL CONTRIBUTE TO MODERATE BUOYANCY WITH MLCAPE OF
1000-2000 J/KG. PRESENCE OF A MODERATE MID-LEVEL SPEED MAX /SAMPLED
IN AMA VWP DATA/ ASSOCIATED WITH A SUBTLE IMPULSE CROSSING THE SRN
ROCKIES IN WATER VAPOR IMAGERY WILL LIKELY YIELD EFFECTIVE SHEAR
SUFFICIENT FOR A FEW SUPERCELLS. GIVEN 35-40 DEG F SURFACE
TEMPERATURE/DEW POINT SPREADS...SEVERE WIND/HAIL WILL BE THE
HAZARDS.

URGENT - IMMEDIATE BROADCAST REQUESTED
SEVERE THUNDERSTORM WATCH NUMBER 222
NWS STORM PREDICTION CENTER NORMAN OK
350 PM MDT SUN MAY 26 2013

THE NWS STORM PREDICTION CENTER HAS ISSUED A

* SEVERE THUNDERSTORM WATCH FOR PORTIONS OF
PARTS OF CENTRAL AND SOUTHEAST MONTANA
NORTHEAST WYOMING

* EFFECTIVE THIS SUNDAY AFTERNOON AND EVENING FROM 350 PM UNTIL
1000 PM MDT.

* PRIMARY THREATS INCLUDE...
SEVERAL LARGE HAIL EVENTS WITH A FEW VERY LARGE HAIL EVENTS TO 2
INCHES IN DIAMETER POSSIBLE
A FEW DAMAGING WIND GUSTS TO 70 MPH POSSIBLE

THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 80
STATUTE MILES EAST AND WEST OF A LINE FROM 60 MILES NORTHEAST OF
LEWISTOWN MONTANA TO 60 MILES SOUTH SOUTHWEST OF BROADUS MONTANA.
FOR A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH
OUTLINE UPDATE (WOUS64 KWNS WOU2).

PRECAUTIONARY/PREPAREDNESS ACTIONS...

REMEMBER...A SEVERE THUNDERSTORM WATCH MEANS CONDITIONS ARE
FAVORABLE FOR SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
AND POSSIBLE WARNINGS. SEVERE THUNDERSTORMS CAN AND OCCASIONALLY
DO PRODUCE TORNADOES.

&&

DISCUSSION...ONGOING STORMS FROM CENTRAL MT INTO NE WY ARE EXPECTED
TO INTENSIFY SOME THE NEXT FEW HOURS AS SURFACE HEATING CONTINUES IN
THE DOWNSTREAM AIR MASS...AND ADDITIONAL STORMS WILL LIKELY DEVELOP
AS THIS AREA IS BRUSHED BY AN EJECTING SPEED MAX OVER THE NRN
ROCKIES. THE COMBINATION OF MODERATE INSTABILITY AND SUFFICIENT
VERTICAL SHEAR WILL SUPPORT THE RISK FOR A FEW SUPERCELLS WITH LARGE
HAIL THE NEXT FEW HOURS. LATER THIS EVENING...STORM MERGERS COULD
LEAD TO THE GROWTH OF A CLUSTER OR LINE SEGMENTS...WITH THE RISK FOR
DAMAGING WINDS.

AVIATION...A FEW SEVERE THUNDERSTORMS WITH HAIL SURFACE AND ALOFT
TO 2 INCHES. EXTREME TURBULENCE AND SURFACE WIND GUSTS TO 60
KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 500. MEAN STORM
MOTION VECTOR 26025.

MESOSCALE DISCUSSION 0805
NWS STORM PREDICTION CENTER NORMAN OK
0303 PM CDT SUN MAY 26 2013

AREAS AFFECTED...PORTIONS OF CENTRAL/WRN NEB

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 262003Z - 262130Z

PROBABILITY OF WATCH ISSUANCE...60 PERCENT

SUMMARY...SCTD SVR TSTMS MAY DEVELOP IN THE 20Z-00Z TIME FRAME.
LARGE HAIL AND DAMAGING WINDS ARE LIKELY...AND A COUPLE OF TORNADOES
WILL ALSO BE POSSIBLE. THIS AREA IS BEING MONITORED FOR A WW.

DISCUSSION...A COMPLEX SCENARIO EXISTS ACROSS CENTRAL/WRN NEB THIS
AFTN AS A WARM FRONT EXTENDS EAST-WEST ACROSS SRN NEB AND AN
INVERTED SFC TROUGH EXTENDS NORTH-SOUTH FROM JUST W OF OGA TO E OF
CDR. A MOIST BOUNDARY LAYER...WITH DEW POINTS IN THE LWR-MID
60S...EXISTS IN THE VICINITY OF THE WARM FRONT AND EAST OF THE SFC
TROUGH. FURTHER...STEEP MID-LEVEL LAPSE RATES OF 8.5 DEG C/KM ALSO
EXIST IN THIS AREA. CONTINUED DIABATIC HEATING WILL RESULT IN A
STRONGLY UNSTABLE AIR MASS WITH MLCAPE IN EXCESS OF 2500 J/KG AND
LOCALLY NEAR 3500 J/KG. DEEP LAYER SHEAR OF 35-45 KTS ACROSS THE
AREA WILL SUPPORT SUPERCELL TSTMS CAPABLE OF VERY LARGE HAIL AND
DAMAGING WINDS. FORECAST SOUNDINGS INDICATE THAT LOW-LEVEL SHEAR
WILL INCREASE BY LATE AFTN/EARLY EVENING AND SUPPORT A THREAT FOR A
TORNADO...ESPECIALLY WITH ANY STORM IN THE VICINITY OF THE WARM
FRONT WHERE LCL HEIGHTS WILL BE MORE FAVORABLE.

CONVECTIVE TRENDS WILL CONTINUE TO BE MONITORED AND A WW MAY BE
NEEDED PRIOR TO 22Z.

DAY1SVR: Day 1 Convective Outlook

SPC AC 261958

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0258 PM CDT SUN MAY 26 2013

VALID 262000Z - 271200Z

...THERE IS A SLGT RISK OF SVR TSTMS FROM THE SRN HIGH PLAINS INTO
PORTIONS OF THE CNTRL AND NRN PLAINS...

...CNTRL PLAINS AREA...

ONLY MINOR CHANGES HAVE BEEN MADE TO THIS PORTION OF THE OUTLOOK.
VISIBLE IMAGERY SHOW CUMULUS INCREASING ALONG N-S CONVERGENCE AXIS
EXTENDING THROUGH WCNTRL NEB FROM A SFC LOW OVER SWRN NEB...AS WELL
AS ALONG THE E-W QUASI-STATIONARY FRONT ACROSS CNTRL NEB. THE
ATMOSPHERE IS BECOMING STRONGLY UNSTABLE WITH MLCAPE APPROACHING
3000 J/KG...BUT STILL APPEARS TO BE CAPPED TO SFC BASED STORMS. AS
THE SFC LAYER CONTINUES TO WARM...HRRR GUIDANCE INDICATE STORMS WILL
DEVELOP OVER WCNTRL NEB BY LATE AFTERNOON. EFFECTIVE SHEAR IS
SUFFICIENT FOR SUPERCELLS...AND 0-2 KM HODOGRAPHS WILL INCREASE IN
SIZE AS THE LLJ STRENGTHENS DURING EARLY EVENING. VERY LARGE HAIL
AND ISOLATED TORNADOES WILL BE THE MAIN INITIAL THREATS...BEFORE
ACTIVITY EVOLVES INTO ONE MORE CLUSTERS LATER THIS EVENING.

...NRN PLAINS...

PRIMARY CHANGE TO THIS REGION WAS TO INTRODUCE A GAP IN THE SIG AND
30% HAIL COVERAGE LINES. A RELATIVE MINIMUM IN STORM COVERAGE MIGHT
OCCUR WHERE CONVECTIVELY MODIFIED AIR HAS BEEN ADVECTED SWWD AND IS
SERVING TO MAINTAIN STRATUS INTO PARTS OF WRN SD. MORE ROBUST
DEVELOPMENT APPEARS MORE LIKELY FARTHER NW WHERE STORMS WILL SPREAD
EWD OFF THE HIGHER TERRAIN OF MT AND NERN WY.

...SRN PLAINS...

WILL MAINTAIN A CONDITIONAL THREAT FOR ISOLATED LARGE HAIL AND
DAMAGING WIND WITH ANY STORMS THAT CAN DEVELOP WITHIN ZONE OF DEEPER
MIXING ON DRYLINE CIRCULATION. ANY STORMS THAT DEVELOP SHOULD REMAIN
ISOLATED.

..DIAL.. 05/26/2013

.PREV DISCUSSION... /ISSUED 1116 AM CDT SUN MAY 26 2013/

...SYNOPSIS...

LITTLE CHANGE TO THE SYNOPTIC PATTERN IS FORECAST THROUGH THE D1
PERIOD WITH UPPER LOWS OVER BC/AB AND OVER NEW ENGLAND INTO THE
CANADIAN MARITIMES. BETWEEN THESE FEATURES...A RIDGE FROM MB/ON
INTO THE MID-MO VALLEY WILL GRADUALLY LOSE AMPLITUDE IN RESPONSE TO
THE EWD PROGRESSION OF A SERIES OF VORTICITY MAXIMA ORIGINATING
WITHIN THE CYCLONIC FLOW REGIME OVER THE WRN STATES. ONE IMPULSE OF
POTENTIAL IMPORTANCE IS APPARENT IN WATER VAPOR IMAGERY OVER THE
GREAT BASIN AS OF MID MORNING. THIS FEATURE IS FORECAST TO
TRANSLATE NEWD INTO THE NRN HIGH PLAINS BY THIS EVENING.

IN THE LOW LEVELS...CONSIDERABLE CONVECTIVE OUTFLOW HAS MASKED THE
SYNOPTIC BOUNDARIES ACROSS THE NRN PLAINS THIS MORNING.
HOWEVER...IT APPEARS THAT A PAIR OF LEE CYCLONES WILL DEEPEN TODAY
OVER CNTRL OR ERN WY AND OVER ERN CO...ALONG A LEE TROUGH/DRY LINE
WHICH WILL EXTEND ALONG THE HIGH PLAINS. A QUASI-STATIONARY
BOUNDARY WILL INTERSECT THE LEE TROUGH OVER ERN WY BEFORE EXTENDING
SEWD THROUGH THE MID-MO INTO MID-MS VALLEYS.

...NRN/CNTRL PLAINS THIS AFTERNOON AND TONIGHT...

THE COLOCATION OF STEEP MIDLEVEL LAPSE RATES AND MODEST BOUNDARY
LAYER MOISTURE CONTENT WILL COMBINE WITH DAYTIME HEATING TO YIELD A
MODERATELY UNSTABLE AIR MASS BY AFTERNOON ALONG AND EAST OF THE LEE
TROUGH WHERE MLCAPE VALUES WILL APPROACH 1000-1500 J/KG OVER ERN
MT...TO AS HIGH AS 2000-3000 J/KG ACROSS PARTS OF WRN NEB INTO WRN
AND CNTRL KS. IN THE WAKE OF THE INITIAL ELEVATED STORMS CURRENTLY
MOVING THROUGH THE MID-MO VALLEY...LATEST MODEL GUIDANCE SUGGESTS
THAT SURFACE-BASED STORM DEVELOPMENT WILL BE MOST PROBABLE BY MID TO
LATE AFTERNOON INVOF THE LEE TROUGH AND FAVORED TERRAIN OVER ERN
PARTS OF MT AND WY...AS WELL AS TO THE NORTHEAST OF THE ERN CO LEE
CYCLONE. ANOTHER AREA OF POTENTIAL STORM INITIATION WILL BE ALONG
OR JUST NORTH OF THE OUTFLOW BOUNDARY/SYNOPTIC FRONT OVER CNTRL OR
N-CNTRL/NERN NEB LATE THIS AFTERNOON INTO EVENING WHERE
CONVERGENCE/UPLIFT IS AUGMENTED AT THE TERMINUS OF A DEVELOPING
LLJ.

ELY/SELY LOW-LEVEL WINDS VEERING TO SWLY AT 25-35 KT IN THE
MIDLEVELS WILL RESULT IN SUFFICIENT VERTICAL SHEAR FOR SUPERCELLS AS
THE INITIAL STORM MODE. LARGE HAIL /SOME SIGNIFICANT/ WILL BE THE
PRIMARY HAZARD WITH THESE STORMS...THOUGH A FEW TORNADOES WILL BE
POSSIBLE. THIS IS ESPECIALLY THE CASE THIS EVENING OVER WRN NEB
WHERE THE STRONGEST BUOYANCY AND DEEP-LAYER SHEAR WILL ALIGN WITH A
CORRIDOR OF ENHANCED LOW-LEVEL SHEAR. BY TONIGHT...STORMS MAY GROW
UPSCALE INTO ONE OR MULTIPLE MCS/S WITH A CONTINUED RISK FOR HAIL
AND DAMAGING WINDS SPREADING EWD INTO THE LOWER ELEVATIONS OF THE
PLAINS.

...SRN HIGH PLAINS THIS AFTERNOON AND EVENING...

STRONG DAYTIME HEATING WILL COMBINE WITH STEEP MIDLEVEL LAPSE RATES
AND BOUNDARY LAYER DEWPOINTS IN THE UPPER 50S TO LOW TO MID 60S TO
YIELD AFTERNOON MLCAPE VALUES OF 1500-3000 J/KG AHEAD OF THE
DRYLINE. MORNING WATER VAPOR IMAGERY SHOWS A LOW-AMPLITUDE
SHORT-WAVE TROUGH MOVING THROUGH THE LOWER-CO VALLEY WHICH WILL
LIKELY REMAIN TO THE WEST OF THE REGION THROUGH TODAY. THUS...WHILE
THE UPPER-LEVEL PATTERN WILL BECOME SLIGHTLY DIFFLUENT BY
27/00Z...LARGE-SCALE FORCING FOR ASCENT WILL REMAIN NEGLIGIBLE. AS
SUCH...STORM INITIATION WILL BE STRONGLY TIED TO THE DEVELOPING
DRYLINE CIRCULATIONS WITH ONLY ISOLATED COVERAGE ANTICIPATED.

THE COMBINATION OF THE MODERATE TO STRONG INSTABILITY AND DEEP-LAYER
SHEAR INCREASING TO 30-35 KT WILL PROMOTE INTENSE STORMS...INCLUDING
THE POSSIBILITY OF SUPERCELLS...WITH THE PRIMARY HAZARDS BEING LARGE
HAIL AND LOCALLY DAMAGING WINDS. STORMS SHOULD TEND TO WEAKEN BY
LATE EVENING INTO TONIGHT AS THE BOUNDARY LAYER COOLS AND
STABILIZES.
