What was reported inside it

Time	Report	Where	Remark
Apr 25, 4:35 AM CDT	TSTM WND GST 40	2 N Albany, MO	ALSO OBSERVED PEA-SIZED HAIL.
Apr 25, 4:49 AM CDT	TSTM WND GST 40	Albany, MO	ESTIMATED 30 TO 40 MPH WIND GUSTS.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The watch it was issued in

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Kansas City, MO wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 25, 3:16 AM CDT, 1 hour 15 minutes earlier.

Area forecast discussion, Apr 25, 3:16 AM CDT, 1 hour 15 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
316 AM CDT FRI APR 25 2008

.DISCUSSION...
YET ANOTHER BUSY NIGHT...WITH SEVERE STORMS MOVING THROUGH
NORTHWESTERN PORTIONS OF THE CWFA.  THESE STORMS ARE STARTING TO
ADVANCE AHEAD OF THE COLD FRONT THAT IS SITUATED FROM THE NORTHWEST
CORNER OF MISSOURI...BACK TO THE SOUTHWEST TO A SURFACE LOW IN
CENTRAL KANSAS. PRESSURE FALLS SHOW THIS LOW WILL BE ADVANCING TO
THE NORTHEAST TOWARD THE KSTJ AREA. SHOULD BE IN THAT AREA BY 12Z.
CURRENT STORMS WILL REMAIN ORGANIZED WITH THE SOUTHWEST LLJ
CONTINUING TO SUPPORT THEM.  THUS THINK BY 12Z...EXTREME NORTHWEST
CORNER OF MISSOURI MAY BE COMING OUT FROM UNDER THE THREAT OF
STORMS...BUT THE REST OF THE CWFA WILL HAVE A GOOD CHANCE OF STORMS
THROUGH THE MORNING HOURS. WITH THIS SURFACE WAVE COMING INTO THE
REGION AND APPROACHING UPPER TROUGH...INCREASING SHEAR WILL ALSO
CONTRIBUTE KEEPING THE SEVERE POTENTIAL WITH THESE STORMS GOING.

FRONT SHOULD ADVANCE EAST OF THE FORECAST AREA BY EARLY AFTERNOON AS
THE UPPER SHORT WAVE TROUGH MOVES INTO KANSAS. MUCH COLDER AIR WILL
BE FEEDING IN BEHIND THE FRONT...SO WILL BE A DAY WHERE MAX
TEMPERATURES WILL BE REACHED EARLY ON...BEFORE THE FRONT MOVES
THROUGH.  RAINFALL WITH THESE STORMS WILL BE INTENSE...BUT NOT
PLANNING ON ANOTHER FLOOD WATCH AS STORMS SHOULD BE MOVING AT A
PRETTY GOOD CLIP. MAY SEE SOME LOCALIZED FLOODING PROBLEMS WITH THE
SATURATED GROUND AND HEAVY RAINFALL FROM THE STORMS...BUT STORMS
SHOULD BE MOVING FAST ENOUGH TO PRECLUDE A WIDESPREAD FLOODING
THREAT SO WILL NOT GO WITH ANY FLOOD WATCH TODAY.

COLDER AIR WILL CONTINUE TO SPILL IN TONIGHT. NOT TOTALLY OUT OF THE
QUESTION SOME LIGHT PRECIPITATION COULD WRAP AROUND THE EXITING
STORM SYSTEM AND AFFECT NORTHERN MISSOURI TONIGHT BUT WILL GO DRY
FOR NOW.

A SECOND SHORT WAVE MOVING OUT OF WESTERN CANADA WILL BE DROPPING
INTO THE MEAN TROUGH POSITION ACROSS THE CENTRAL PART OF THE COUNTRY
OVER THE WEEKEND. THIS SHORT WAVE WILL BRING THE CHANCE OF RAIN TO
THE FORECAST AREA SATURDAY NIGHT...BUT MOISTURE WILL BE LIMITED WITH
THIS WAVE AS GULF WILL BE PRETTY MUCH CUT OFF.  CYCLONIC CURVATURE
SITTING ACROSS THE AREA ON SUNDAY MAY PRODUCE SHOWERS IN THE
FORECAST AREA ON SUNDAY...WITH THE MOST LIKELY AREA FOR THIS TO
OCCUR IN NORTHEAST PORTIONS OF THE CWFA.  THIS SECONDARY WAVE WILL
REINFORCE THE COLD AIR ACROSS THE REGION FOR SUNDAY. WILL NOT GO
WITH ANY FREEZING TEMPERATURES AT THIS POINT FOR MONDAY
MORNING...BUT WOULD NOT BE SURPRISED TO SEE READINGS NEAR THE
FREEZING MARK ALONG THE IOWA BORDER.

/120 AM CDT FRI APR 25 2008/
INCREASING SSWLY LOW LEVEL JET NOW IN EXCESS OF 70KTS IS FEEDING IN
RICH MOISTURE LADEN AND UNSTABLE AIR INTO COMPLEX OF STRONG TO
SEVERE THUNDERSTORMS OVER NORTH CENTRAL/NORTHEAST KS/SOUTHEASTERN
NE. SMALL BOW ECHO STRUCTURES VISIBLE ON RADAR BULGING EASTWARD ON
NOSE OF LOW LEVEL JET INCREASING THE LIKELIHOOD OF DAMAGING WINDS.
IN ADDITION ROTATING AND SLIGHTLY ELEVATED STORMS WITH STRONG
UPDRAFTS SENDING 50DBZ ECHOES IN EXCESS OF 30K FEET WILL BE
SUFFICIENT TO PRODUCE LARGE HAIL IN EXCESS OF 1 INCH IN DIAMETER.
SEVERE THREAT LIKELY TO CONTINUE THROUGH THE NIGHT.

.AVIATION...
FOR THE 06Z TAFS...VFR CEILINGS WILL PREVAIL THROUGH THE EARLY
MORNING HOURS BEFORE MVFR CEILINGS PUSH IN FROM EASTERN KS. ISOLATED
CONVECTION POSSIBLE AT STJ UNTIL THE COLD FRONT AND ITS ASSOCIATED
SHOWERS AND THUNDERSTORMS ARRIVE AROUND 10Z. MCI AND MKC SHOULD STAY
DRY UNTIL AROUND 11Z WHEN THE COLD FRONT ARRIVES. THE CONVECTIVE
SQUALL LINE IS MORE LIKELY TO BE A BROKEN THAN SOLID LINE WITH A
HIGHER PROBABILITY OF OCCURRENCE AT STJ. GUSTY SOUTH WINDS WILL VEER
TO THE SOUTHWEST FOR A FEW HOURS AFTER FRONTAL PASSAGE WITH BROKEN
MVFR CEILINGS AS DRIER AIR AND SUBSIDENCE SPREAD ACROSS THE REGION.
MAY BE ENOUGH DRY AIR ENTRAINED TO SCATTER OUT CLOUDS ALL TOGETHER.
HOWEVER...THIS SHOULD BE SHORTLIVED AS WINDS VEER TO THE
WEST-NORTHWEST AND INCREASE AS COLD AIR ADVECTION BRINGS IN A DECK
OF VFR CLOUD COVER. BY LATE TOMORROW EVENING EXPECT THE CLOUDS TO
CLEAR COMPLETELY AS THE WRAP AROUND CLOUD COVER EXITS EAST.

101 PM CDT THU APR 24 2008

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHWEST...NORTH CENTRAL
AND WEST CENTRAL MISSOURI...AS WELL AS EXTREME EASTERN KANSAS.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

 A STRENGTHENING LOW PRESSURE SYSTEM AND ASSOCIATED COLD FRONT WILL
 DEVELOP ACROSS KANSAS AND LIFT TOWARD FAR NORTHWEST MISSOURI AND
 ADJACENT NORTHEAST KANSAS BY DAYBREAK FRIDAY. THUNDERSTORMS COULD
 IMPACT AREAS NORTH AND WEST OF A ST. JOSEPH TO BETHANY LINE AFTER
 2 AM.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

 A STRENGTHENING COLD FRONT AND DRY LINE WILL MOVE EAST ACROSS
 MISSOURI ON FRIDAY. WITH A WARM AND HUMID AIRMASS IN PLACE AHEAD
 OF THIS FRONT...ISOLATED TO SCATTERED THUNDERSTORMS ARE EXPECTED
 TO DEVELOP ACROSS THE REGION. DEPENDING ON THE TIMING OF THIS
 FRONT...THE COMBINATION OF INSTABILITY AND SHEAR WILL BECOME
 INCREASINGLY FAVORABLE FOR SEVERE THUNDERSTORM DEVELOPMENT...
 INCLUDING SUPERCELLS WITH A THREAT FOR LARGE HAIL AND DAMAGING WIND
 GUSTS. AT THIS TIME...THE GREATEST THREAT FOR THUNDERSTORMS AND
 SEVERE WEATHER APPEARS TO BE EAST OF THE INTERSTATE 35
 CORRIDOR...INCREASING ACROSS CENTRAL AND NORTHEAST MISSOURI INTO
 THE EARLY AFTERNOON HOURS. DUE TO THE FAST STORM MOTION...
 WIDESPREAD HEAVY RAINFALL AND FLOODING IS NOT EXPECTED.

 ON SATURDAY NIGHT AND INTO SUNDAY...ANOTHER COLD FRONT WILL BE
 SWINGING THROUGH THE REGION. AT THIS TIME...IT IS TOO SOON TO TELL
 IF THERE WILL BE ANY SEVERE POTENTIAL WITH THIS SYSTEM. COLDER AIR
 IS EXPECTED BEHIND THIS COLD FRONT WITH A POTENTIAL FOR A FROST BY
 MONDAY MORNING.

.SPOTTER INFORMATION STATEMENT...

 SPOTTER ACTIVATION MAY BE NEEDED LATE TONIGHT IN NORTHEAST KANSAS
 AND NORTHWEST MISSOURI. SPOTTERS MAY ALSO BE NEEDED DURING THE DAY
 ON FRIDAY AS THE COLD FRONT MOVES TO THE EAST ACROSS MISSOURI. ALSO
 SPOTTERS ARE ENCOURAGED TO CALL IN RAINFALL AMOUNTS AND ANY
 OBSERVED FLOODING.
