SEVERE THUNDERSTORM WATCH NUMBER 555
NWS STORM PREDICTION CENTER NORMAN OK
1005 PM CDT MON JUL 28 2025
THE NWS STORM PREDICTION CENTER HAS ISSUED A
* SEVERE THUNDERSTORM WATCH FOR PORTIONS OF
NORTHERN, CENTRAL, AND EASTERN IOWA
SOUTHEAST MINNESOTA
* EFFECTIVE THIS MONDAY NIGHT AND TUESDAY MORNING FROM 1005 PM
UNTIL 400 AM CDT.
* PRIMARY THREATS INCLUDE...
WIDESPREAD DAMAGING WINDS AND ISOLATED SIGNIFICANT GUSTS TO 85
MPH LIKELY
ISOLATED LARGE HAIL EVENTS TO 1.5 INCHES IN DIAMETER POSSIBLE
A TORNADO OR TWO POSSIBLE
SUMMARY...AN INTENSE AND WELL-ORGANIZED CONVECTIVE LINE IS MOVING
QUICKLY INTO NORTHEAST IA. THIS LINE SHOULD REMAIN INTENSE AS IT
CONTINUES PROGRESSING EASTWARD OR PERHAPS EAST-SOUTHEASTWARD FOR THE
NEXT SEVERAL HOURS. STRONG GUSTS ARE LIKELY WITHIN THIS LINE,
INCLUDING THE POTENTIAL FOR GUST REACHING TO AROUND 85 MPH. A BRIEF
LINE-EMBEDDED TORNADO IS POSSIBLE AS WELL. ADDITIONALLY, ANOTHER
CONVECTIVE LINE IS MOVING SOUTHEASTWARD INTO MORE OF SOUTHEAST MN.
DAMAGING GUSTS ARE POSSIBLE WITHIN THIS LINE FOR THE NEXT FEW HOURS
AS WELL.
THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 55
STATUTE MILES NORTH AND SOUTH OF A LINE FROM 35 MILES SOUTH OF
SPENCER IA TO 50 MILES NORTH NORTHEAST OF CEDAR RAPIDS IA. FOR A
COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE
UPDATE (WOUS64 KWNS WOU5).
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.

CONCERNING...SEVERE THUNDERSTORM WATCH 553...555...
VALID 290344Z - 290545Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 553, 555
CONTINUES.
SUMMARY...ISOLATED DAMAGING WIND GUSTS WILL BE POSSIBLE OVER THE
NEXT FEW HOURS ACROSS PARTS OF SOUTHEAST MINNESOTA, FAR NORTHEAST
IOWA AND WESTERN WISCONSIN. ALTHOUGH A SEVERE THREAT WILL LIKELY
PERSIST, THE THREAT SHOULD BE TOO ISOLATED TO THE EAST OF THE
ONGOING WATCHES FOR NEW WATCH ISSUANCE.
DISCUSSION...THE LATEST HI-RESOLUTION RADAR IMAGERY FROM
MINNEAPOLIS, MINNESOTA SHOWS A WELL-DEVELOPED SEVERE LINE SEGMENT
FROM WESTERN WISCONSIN INTO SOUTHEAST MINNESOTA. THIS LINE IS
LOCATED ALONG THE NORTHEASTERN EDGE OF A MODERATELY UNSTABLE
AIRMASS, WHERE MLCAPE IS ESTIMATED BY THE RAP IN THE 1000 TO 2000
J/KG RANGE, AND SURFACE DEWPOINTS ARE IN THE LOWER 70S F. AN
ISOLATED WIND-DAMAGE THREAT MAY BE MAINTAINED WITH THE STRONGER
SEGMENTS WITHIN THE LINE, AS IT TRACKS SOUTH-SOUTHEASTWARD ALONG THE
INSTABILITY GRADIENT OVER THE NEXT COUPLE OF HOURS. THE LATEST RAP
SHOWS WEAKER INSTABILITY PRESENT OVER FAR NORTHEAST IOWA AND
SOUTHWEST WISCONSIN, SUGGESTING THAT THE LINE SHOULD GRADUALLY
WEAKEN AS IT MOVES FURTHER SOUTHEAST.

SUMMARY...A COUPLE INSTANCES OF SEVERE HAIL MAY ACCOMPANY ONGOING
STORMS IN TEMPORALLY EXTENDED SEVERE THUNDERSTORM WATCH 551. A
SEVERE GUST IS ALSO POSSIBLE WITH DECAYING STORMS OVER EASTERN MT.
DISCUSSION...MULTIPLE SUPERCELLS HAVE RECENTLY DEVELOPED OVER
SOUTH-CENTRAL MT BEHIND AN OUTFLOW BOUNDARY, WHERE SEVERE HAIL HAS
BEEN REPORTED. IN THIS REGION, STRONG FLOW ALOFT IS CONTRIBUTING TO
OVER 60 KTS OF EFFECTIVE BULK SHEAR, WHICH MAY SUPPORT CONTINUED
SUPERCELL STRUCTURES AND AN ASSOCIATED SEVERE HAIL RISK FOR AT LEAST
A COUPLE MORE HOURS. FARTHER TO THE NORTHEAST, A LOOSELY ORGANIZED
LINE OF LIKELY DECAYING STORMS PERSISTS OVER EASTERN MT, AND A
SEVERE GUST IS POSSIBLE WITH THIS COMPLEX.

MINNESOTA AND NORTHWEST IOWA OVER THE NEXT COUPLE OF HOURS. SEVERE
GUSTS AND HAIL WILL BE THE PRIMARY THREATS. GUSTS OVER 85 MPH WILL
BE POSSIBLE. WEATHER WATCH ISSUANCE WILL BE NEEDED SOON.
DISCUSSION...THE LATEST MOSAIC RADAR IMAGERY SHOWS AN MCS FROM
SOUTH-CENTRAL MINNESOTA EXTENDING SOUTHWESTWARD INTO FAR NORTHWEST
IOWA. THE STRONGEST PART OF THE MCS IS LOCATED BETWEEN SIOUX FALLS
AND SIOUX CITY, WHERE INDICATIONS SUGGEST THAT A COLD POOL IS
STARTING TO ORGANIZE. FROM THIS PART OF THE MCS, A BOWING LINE
SEGMENT IS EXPECTED TO CONTINUE FORMING, MOVING SOUTHEASTWARD ALONG
A SHARP GRADIENT OF STRONG INSTABILITY. THIS SEVERE LINE SEGMENT
SHOULD AFFECT PARTS OF NORTHWEST AND CENTRAL IOWA OVER THE NEXT FEW
HOURS. ALONG THE TRACK OF THIS SEVERE LINEAR MCS, WIDESPREAD
DAMAGING WIND GUSTS MAY OCCUR, WITH THE STRONGEST WIND GUSTS NEAR
THE APEX OF THE BOWING LINE SEGMENT. SIGNIFICANT WIND GUSTS WILL BE
LIKELY.

VALID 290100Z - 291200Z
...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS FROM SOUTHEAST
SOUTH DAKOTA INTO SOUTHERN MINNESOTA AND NORTHERN IOWA...
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER MUCH OF
CENTRAL MONTANA...
...SUMMARY...
A CORRIDOR OF SIGNIFICANT DAMAGING WINDS REMAINS POSSIBLE FROM
SOUTHEAST SOUTH DAKOTA AND INTO SOUTHERN MINNESOTA AND NORTHERN
IOWA. SPORADIC LARGE HAIL OR AN ISOLATED TORNADO MAY ALSO OCCUR.
...SD...MN...NE...IA...
SCATTERED SEVERE STORMS PERSIST THIS EVENING FROM FAR NORTHERN NE
ACROSS EASTERN SD AND INTO WEST-CENTRAL MN. A COMPLEX MIXTURE OF
STORM MODES CURRENTLY EXISTS, BUT LATEST TRENDS INDICATE A
LARGER-SCALE DAMAGING WIND RISK MAY BE EVOLVING.
PREVIOUSLY TORNADIC SUPERCELLS OVER SD ARE NOW MOVING GENERALLY
EASTWARD ALONG THE SD/NE BORDER, WITH ADDITIONAL CELLS FILLING IN
INTO NORTHEAST SD AND WESTERN MN. OF PARTICULAR CONCERN ARE STORMS
WEST THROUGH SOUTHWEST OF THE SIOUX FALLS AREA. IF THESE CAN CONGEAL
FURTHER WITH A MORE CONSOLIDATED OUTFLOW, THE VERY MOIST AND
UNSTABLE AIR MASS MAY SUPPORT SIGNIFICANT DAMAGING GUSTS DOWNSTREAM
INTO NORTHERN IA AND SOUTHERN MN LATER THIS EVENING/TONIGHT.
THE LINE OF STORMS CURRENTLY OVER WEST-CENTRAL MN IS ALSO BECOMING
BETTER ORGANIZED, WITH STRONG DEEP-LAYER MEAN WINDS ACROSS THIS
REGION. THIS MAY COUNTERACT THE LESSER INSTABILITY VALUES OVER THIS
AREA AND TOWARD THE MS RIVER LATER THIS EVENING.
FINALLY, IT IS UNCLEAR HOW FAR SOUTH THE SOUTHERN FRINGE OF THE
SEVERE WIND RISK MAY BE. THE OAX 00Z SOUNDING REMAINS VERY UNSTABLE,
WITH A SURMOUNTABLE WARM NOSE GIVEN AN ORGANIZED CONVECTIVE SYSTEM.
AS SUCH, SEVERE PROBABILITIES WERE NUDGED A BIT FARTHER SOUTH.
...MT...
A COMPLEX OF THUNDERSTORMS IS MOVING EAST ACROSS CENTRAL MT, WITH
AREAS OF SEVERE HAIL AND WIND INDICATED ON RADAR. MODERATE
DEEP-LAYER SHEAR AND STEEP LAPSE RATES ALOFT ARE ALLOWING FOR A FEW
LONGER-LIVED CELLS WITH HAIL. CAPPING WILL BE SLOW TO MATERIALIZE
THIS EVENING GIVEN THE MOIST LOW-LEVEL AIR MASS, AND AS SUCH A FEW
SEVERE STORMS MAY BE POSSIBLE INTO EAST-CENTRAL MT.
