PM CDT.
HAIL TO 2 INCHES IN DIAMETER...THUNDERSTORM WIND GUSTS TO 70
MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE AREAS.
THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 70
STATUTE MILES EAST AND WEST OF A LINE FROM 40 MILES WEST
NORTHWEST OF ROCKFORD ILLINOIS TO 50 MILES EAST OF COLUMBIA
MISSOURI. FOR A COMPLETE DEPICTION OF THE WATCH SEE THE
ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU1).
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...LINE OF THUNDERSTORMS IS EXPECTED TO INCREASE EARLY
THIS AFTERNOON AND DEVELOP ENEWD ACROSS WW ALONG STRONG SURFACE COLD
FRONT NOW MOVING INTO ERN IA/CENTRAL MO. STRONG ASCENT AND MARGINAL
INSTABILITY SHOULD SUPPORT BROKEN LINE OF STORMS...WITH SUFFICIENT
SHEAR FOR SMALL LINES AND A FEW SUPERCELLS. PRIMARY SEVERE THREAT
WILL BE MARGINAL SEVERE HAIL INITIALLY...ALTHOUGH POTENTIAL FOR
DAMAGING WINDS AND EVEN A BRIEF TORNADO WILL LIKELY INCREASE THROUGH
THE LATE AFTERNOON.

It's quite common, and there are several reasons:
1) Tornadoes can occur in any severe thunderstorm, local/small-scale wind patterns can spin up tornadoes unexpectedly.
2) When a severe thunderstorm watch is issued, the tornado risk is never zero (they always give a small number), just that they are generally too few in number to warrant a tornado watch (the main threats are wind and/or hail).
3) Sometimes patterns can change quickly and the atmosphere can unexpectedly turn favorable for tornadoes. (Usually when that happens, a tornado watch is issued shortly thereafter.)
It is common also to see severe thunderstorm or tornado warnings when there are no watches in effect.

...MID MS/LWR OH VALLEY INTO THE GREAT LAKES REGION...
VIGOROUS SHORT WAVE IMPULSE IS JUST NOW IN THE PROCESS OF TAKING ON
A MORE NEUTRAL TO NEGATIVE TILT AS IT BEGINS TO LIFT NORTHEAST OF
THE CENTRAL PLAINS. AND...WITH THE MID LEVEL COLD CORE LAGGING TO
THE WEST OF THE MOIST WARM SECTOR OF SURFACE CYCLONE NOW MIGRATING
NORTHEASTWARD INTO WESTERN WISCONSIN...MID-LEVEL LAPSE RATES ARE NOT
AS STEEP AS THEY COULD BE. COUPLED WITH CONSIDERABLE LINGERING
LOW-LEVEL CLOUD COVER BENEATH A SUBSIDENT/ CAPPING MID-LEVEL DRY
SLOT...PRE-FRONTAL MIXED LAYER CAPE IS STILL WEAK AND GENERALLY ONLY
MAXIMIZED IN A NARROW BAND ALONG THE FRONTAL ZONE EXTENDING
NORTHEAST OF THE OZARK PLATEAU INTO THE SURFACE LOW CENTER.
THIS HAS SLOWED THE INTENSIFICATION OF ONGOING DEVELOPING FRONTAL
CONVECTIVE BAND...BUT RUC GUIDANCE IS SUGGESTIVE THAT MIXED LAYER
CAPE WILL PROBABLY APPROACH/EXCEED 1000 J/KG IN THE PEAK AFTERNOON
HEATING. IN THE PRESENCE OF STRONG DEEP LAYER SHEAR NEAR A 70+ KT
500 MB JET CORE...WHICH IS PROGGED TO STRENGTH EAST OF THE UPPER
TROUGH LATER TODAY/TONIGHT...EVOLUTION OF SEVERE SQUALL LINE WITH
POSSIBLE EMBEDDED SUPERCELLS...IS EXPECTED TO PROCEED ACROSS EASTERN
MISSOURI/EXTREME EASTERN IOWA INTO ILLINOIS AND SOUTHERN/ EASTERN
WISCONSIN INTO EARLY EVENING.
IN THE WAKE OF AN INITIAL MID-LEVEL IMPULSE ALREADY LIFTING THROUGH
MICHIGAN...AND PROGGED INTO ONTARIO BY EARLY EVENING...VEERING
SURFACE FLOW IS REDUCING THE SIZE OF LOW-LEVEL HODOGRAPHS BENEATH
35-40 KT SOUTHERLY 850 MB FLOW. AND...A STRENGTHENING MID-LEVEL CAP
MAY CONTINUE TO INHIBIT ISOLATED CONVECTIVE DEVELOPMENT IN ADVANCE
OF FRONTAL SQUALL. THIS IS CONTRIBUTING TO UNCERTAINTY CONCERNING
THE EXTENT OF TORNADO POTENTIAL IN PROXIMITY TO THE SURFACE CYCLONE.
BUT...LOW-LEVEL HODOGRAPHS WILL STILL BE LARGE ENOUGH TO SUPPORT A
RISK FOR TORNADOES IN SUPERCELLS WITHIN THE SQUALL LINE AND PERHAPS
JUST AHEAD IT...PARTICULARLY ACROSS PARTS OF CENTRAL/EASTERN
WISCONSIN. ISOLATED TORNADOES ARE ALSO POSSIBLE WITH STORM
DEVELOPMENT NOW OCCURRING IN ADVANCE OF INITIAL IMPULSE ACROSS LOWER
MICHIGAN LATE THIS AFTERNOON. OTHERWISE...THE RISK FOR LARGE HAIL
WILL EXIST WITH MOST STORMS...AND FAST SQUALL LINE MOTION WITHIN A
40+ KT SOUTHWESTERLY MEAN ENVIRONMENTAL FLOW WILL CONTRIBUTE TO
POTENTIAL FOR DAMAGING WIND GUSTS.
THE SEVERE THREAT IS EXPECTED TO WANE LATE THIS EVENING WITH LOSS OF
DAYTIME HEATING...BUT SPORADIC WIND DAMAGE/HAIL MAY CONTINUE IN
CONVECTION SPREADING ACROSS THE GREAT LAKES REGION AND OHIO VALLEY
OVERNIGHT.
...TEXAS...
DEEP LAYER SHEAR IS WEAK...BUT DIVERGENT UPPER FLOW FIELD BETWEEN
THE POLAR TROUGH TO THE NORTH...AND THE SUBTROPICAL STREAM TO THE
SOUTH...PROBABLY WILL ENHANCE CONVECTIVE DEVELOPMENT NOW UNDERWAY
ALONG THE FRONT ACROSS PARTS OF CENTRAL INTO NORTHEAST TEXAS. WITH
MIXED LAYER CAPE ON THE ORDER OF 2000-3000 J/KG AHEAD OF THE
FRONT...PARTICULARLY IN THE VICINITY OF THE FRONT/DRY LINE
INTERSECTION SOUTHWEST OF THE AUSTIN/TEMPLE AREA...SEVERE STORMS ARE
POSSIBLE AS INHIBITION WEAKENS LATE THIS AFTERNOON. LARGE HAIL IS
LIKELY IN MOST ACTIVITY. AND...THERMODYNAMIC PROFILES WITH A FAIRLY
DEEP MIXED BOUNDARY LAYER AND LOW MID-LEVEL HUMIDITY LEVELS...COULD
PROVE SUPPORTIVE OF ISOLATED STRONG DOWNBURSTS AND SURFACE COLD POOL

OF FRONTAL SQUALL. THIS IS CONTRIBUTING TO UNCERTAINTY CONCERNING
THE EXTENT OF TORNADO POTENTIAL IN PROXIMITY TO THE SURFACE CYCLONE.
BUT...LOW-LEVEL HODOGRAPHS WILL STILL BE LARGE ENOUGH TO SUPPORT A
RISK FOR TORNADOES IN SUPERCELLS WITHIN THE SQUALL LINE AND PERHAPS
JUST AHEAD IT...PARTICULARLY ACROSS PARTS OF CENTRAL/EASTERN
WISCONSIN. ISOLATED TORNADOES ARE ALSO POSSIBLE WITH STORM
DEVELOPMENT NOW OCCURRING IN ADVANCE OF INITIAL IMPULSE ACROSS LOWER
MICHIGAN LATE THIS AFTERNOON. OTHERWISE...THE RISK FOR LARGE HAIL
WILL EXIST WITH MOST STORMS...AND FAST SQUALL LINE MOTION WITHIN A
40+ KT SOUTHWESTERLY MEAN ENVIRONMENTAL FLOW WILL CONTRIBUTE TO
POTENTIAL FOR DAMAGING WIND GUSTS.
THE SEVERE THREAT IS EXPECTED TO WANE LATE THIS EVENING WITH LOSS OF
DAYTIME HEATING...BUT SPORADIC WIND DAMAGE/HAIL MAY CONTINUE IN
CONVECTION SPREADING ACROSS THE GREAT LAKES REGION AND OHIO VALLEY
OVERNIGHT.
...TEXAS...
DEEP LAYER SHEAR IS WEAK...BUT DIVERGENT UPPER FLOW FIELD BETWEEN
THE POLAR TROUGH TO THE NORTH...AND THE SUBTROPICAL STREAM TO THE
SOUTH...PROBABLY WILL ENHANCE CONVECTIVE DEVELOPMENT NOW UNDERWAY
ALONG THE FRONT ACROSS PARTS OF CENTRAL INTO NORTHEAST TEXAS. WITH
MIXED LAYER CAPE ON THE ORDER OF 2000-3000 J/KG AHEAD OF THE
FRONT...PARTICULARLY IN THE VICINITY OF THE FRONT/DRY LINE
INTERSECTION SOUTHWEST OF THE AUSTIN/TEMPLE AREA...SEVERE STORMS ARE
POSSIBLE AS INHIBITION WEAKENS LATE THIS AFTERNOON. LARGE HAIL IS
LIKELY IN MOST ACTIVITY. AND...THERMODYNAMIC PROFILES WITH A FAIRLY
DEEP MIXED BOUNDARY LAYER AND LOW MID-LEVEL HUMIDITY LEVELS...COULD
PROVE SUPPORTIVE OF ISOLATED STRONG DOWNBURSTS AND SURFACE COLD POOL
DEVELOPMENT.

Oh, fun, our first tornado watch. It's quite humid outside, but the sun wasn't out for long today. Sky is very dark right now, and we're getting rained on, but the severe stuff is directly to the west, and then to the southwest. I have rehearsal tonight and won't get to keep up to date with what's going on. Hopefully our stage manager will have access to a weather radio or something similar should a tornado develop while we're there....

Yay, thanks, Bunk! Reminds me..I have a bottle of wine that I picked up in Freiburg that I should probably pop open one of these days....
Wind's picking up a lot now. They extended the SVR to the west so it's just barely missing Madison by the north and west. This little bit will miss us I think. Not so sure about the stuff in northern IL and NE IA....

Re: Severe weather/outbreak? - April 23-25
Not streaming, but weather updates with severe weather video can be found: http://www.nbc15.com/weather. It's possible they stream during Madison warnings, but I'm not sure yet.
