Started a new thread, knowing we have possibly a significant threat tomorrow in addition to today's widespread severe weather.
The MDT for tomorrow was surely a surprise though!

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1215 PM CDT WED APR 23 2008
VALID 241200Z - 251200Z
...THERE IS A MDT RISK OF SVR TSTMS THU AFTN/EVE ACROSS MUCH OF
SOUTHERN/EASTERN NEBRASKA...KANSAS...AND PARTS OF SOUTHWESTERN
IOWA/NORTHWESTERN MISSOURI....
...THERE IS A SLGT RISK OF SVR TSTMS SURROUNDING THE MDT RISK
AREA...ACROSS MUCH OF THE MID MO VALLEY SOUTHWARD THROUGH THE
PLAINS....
...SYNOPSIS...
MODELS INDICATE THAT BROAD CYCLONIC UPPER FLOW WILL PERSIST ACROSS
MUCH OF WESTERN NORTH AMERICA THROUGH THIS FORECAST PERIOD... AROUND
A WESTERN CANADIAN POLAR LOW...WITHIN A BELT OF STRONGER POLAR
WESTERLIES TO ITS SOUTH...FROM THE EASTERN PACIFIC THROUGH THE
CENTRAL ROCKIES/UPPER MISSISSIPPI VALLEY...AND WITHIN THE
SUBTROPICAL WESTERLIES ACROSS THE NORTHERN MEXICAN PLATEAU/RIO
GRANDE VALLEY. DOWNSTREAM...UPPER RIDGING WILL REMAIN PROMINENT
ACROSS EASTERN CANADA AND THE UPPER GREAT LAKES...AND EAST OF THE
MISSISSIPPI VALLEY.
WITHIN THIS PATTERN...THE MOST SIGNIFICANT FEATURE OF INTEREST FOR
THURSDAY INTO EARLY FRIDAY APPEARS TO BE THE COLD CLOSED LOW NOW
MIGRATING INLAND ACROSS THE PACIFIC NORTHWEST COAST. MODELS SUGGEST
THAT THIS SYSTEM WILL ACCELERATE EAST SOUTHEASTWARD LATER
TODAY/TONIGHT...BEFORE CONTINUING TO DIG ACROSS THE EASTERN GREAT
BASIN/CENTRAL ROCKIES AND CENTRAL HIGH PLAINS BY 12Z FRIDAY.
ASSOCIATED FORCING IS EXPECTED TO CONTRIBUTE TO THE CONTINUATION OF
WIDESPREAD CONVECTIVE DEVELOPMENT...NOW UNDERWAY...ACROSS A LARGE
PORTION OF THE CENTRAL UNITED STATES.
A MOIST LOW-LEVEL AIR MASS IS ALREADY IN PLACE ACROSS MUCH OF THE
SOUTHERN PLAINS. AND...THIS MOISTURE WILL CONTINUE TO ADVECT
NORTHWARD AROUND THE WESTERN EDGE OF A RETREATING SURFACE
RIDGE...THROUGH THE CENTRAL PLAINS...AND AHEAD OF A COLD FRONT
ADVANCING INTO THE NORTHERN PLAINS INTO THE UPPER MISSISSIPPI
VALLEY. BENEATH STEEP MID-LEVEL LAPSE RATES ASSOCIATED WITH A
SUBSTANTIAL ELEVATED MIXED LAYER FORECAST TO SPREAD OFF THE
ROCKIES/PLATEAU REGION...THIS WILL CONTRIBUTE TO SEASONABLY LARGE
CONDITIONAL AND CONVECTIVE INSTABILITY OVER MUCH OF THE PLAINS/UPPER
MISSISSIPPI VALLEY.
...PLAINS/MISSISSIPPI VALLEY REGION...
UNCERTAINTIES DO EXIST CONCERNING THE MAGNITUDE/EXTENT OF THE
CONVECTIVE POTENTIAL ACROSS THE PLAINS FOR THIS PERIOD. RATHER
SIGNIFICANT MID-LEVEL INHIBITION WILL EXIST AND PERSIST ACROSS A
LARGE PORTION OF THE CENTRAL/SOUTHERN PLAINS. AND...FLOW FIELDS/
DEEP LAYER...AND LOW-LEVEL...SHEAR MAY BE INITIALLY MARGINAL DUE TO
PERHAPS A SOMEWHAT LATE ARRIVAL OF THE APPROACHING UPPER IMPULSE
INTO THE CENTRAL ROCKIES/HIGH PLAINS REGION.
HOWEVER...EXTENSIVE EARLY CONVECTIVE DEVELOPMENT...PRIMARILY
ASSOCIATED WITH A WEAKENING SHORT WAVE EMANATING FROM THE
SUBTROPICAL STREAM...IS EXPECTED TO SHIFT EAST OF THE PLAINS
EARLY...ALLOWING FOR ABUNDANT SURFACE HEATING SOUTH/EAST OF THE
NORTHERN PLAINS COLD FRONT...AND CENTRAL/SOUTHERN HIGH PLAINS DRY
LINE. THIS INITIAL THUNDERSTORM ACTIVITY IS EXPECTED TO REMAIN
MOSTLY BASED IN AN ELEVATED WARM ADVECTION REGIME EAST OF THE
STRONGER CAP...BUT AT LEAST AN ISOLATED/GENERALLY MARGINAL SEVERE
HAIL THREAT MAY ACCOMPANY CONVECTION AS IT SPREADS ACROSS AND EAST
OF THE MID/UPPER MISSISSIPPI VALLEY DURING THE DAY. MEANWHILE...
MIXED LAYER CAPE IN THE MOIST PLAINS BOUNDARY LAYER...WITH SURFACE
DEW POINTS IN THE MID/UPPER 60S...IS EXPECTED TO INCREASE IN EXCESS
OF 2000 J/KG BY LATE AFTERNOON...ACROSS MUCH OF EASTERN/ SOUTHERN
NEBRASKA...SOUTHWARD INTO TEXAS.
MID/UPPER FORCING MAY BEGIN TO GRADUALLY INCREASE IN THE VICINITY OF
THE COLD FRONT/DRY LINE INTERSECTION ACROSS PARTS OF CENTRAL/
SOUTHWEST NEBRASKA INTO WESTERN KANSAS BY LATE AFTERNOON. THIS IS
WHERE THE INITIATION OF STORMS APPEARS MOST PROBABLE...BUT THE CAP
MAY WEAKEN SUFFICIENTLY FOR AT LEAST ISOLATED TO WIDELY SCATTERED
STORMS SOUTHWARD ALONG DRY LINE INTO WEST CENTRAL TEXAS BY EARLY
EVENING...BENEATH DIFLUENT UPPER FLOW.
GIVEN INSTABILITY...DEEP LAYER SHEAR IS EXPECTED TO BECOME
SUFFICIENT FOR SUPERCELLS CAPABLE OF PRODUCING VERY LARGE HAIL AND
LOCALLY DAMAGING WIND GUSTS. TORNADO POTENTIAL IS A BIT MORE
UNCERTAIN. BUT...A STRENGTHENING OF LOW-LEVEL AND MID-LEVEL WIND
FIELDS IS PROGGED TOWARD EARLY THURSDAY EVENING...ALONG WITH AN
ENLARGING OF CLOCKWISE CURVED LOW-LEVEL HODOGRAPHS...TO SUPPORT MORE
FAVORABLE CONDITIONS FOR TORNADOES...PARTICULARLY ACROSS KANSAS INTO
SOUTH CENTRAL NEBRASKA. AN ISOLATED LONG-LIVED SUPERCELL OR TWO
ACCOMPANIED BY PERSISTENT TORNADIC ACTIVITY DOES NOT APPEAR OUT OF
THE QUESTION...BEFORE MID/UPPER FORCING SUPPORTS INCREASINGLY
WIDESPREAD STRONG/SEVERE CONVECTION ACROSS PARTS OF NEBRASKA/KANSAS
THROUGH THE MIDDLE MISSOURI VALLEY THURSDAY NIGHT.

Re: Severe weather/outbreak? - April 23-25
Over 75 dbz on the Dyess AFB radar base reflectivity. Now, maybe Wall-Cloud knows the magic VIL of the day just South of the AMA and LBB NWS CWA, and can dial that up and tell us if that is baseball, softball or basketball sized hail.
