    Storm Summary Number 7 for Southwest into Central U.S. Heavy
    Rainfall
    NWS Weather Prediction Center College Park MD
    900 AM MDT Fri Oct 02 2026
    
    ...Heavy rainfall and flash flooding threat focuses on southern
    and central Texas today, while rain gradually winds down across
    the Central Plains and Midwest remains lighter and beneficial...
    
    Flash Flood Warnings are in effect for portions of the Heart of
    Texas.
    
    Flood Warnings remain in effect dotted across the central Plains
    from central Kansas, northern Missouri, central and eastern Iowa
    into northwest Illinois.
    
    Flood Advisories are in effect for portions of south-central Texas.
    
    Flood Watches are in effect for much of Eastern Texas.
    
    For a detailed graphical depiction of the latest watches, warnings
    and advisories, please see www.weather.gov
    
    At 800 AM MDT...The well defined stationary front exists from
    northern Coahuila in Mexico, across central Texas into
    south-central Oklahoma, through southern Missouri and into the
    Ohio River Valley.  A few surface waves still exist along the
    front but are generally transient in time, though the most
    persistent low exists in central Texas with a 1012 mb (29.88 in
    Hg) pressure. Deep layer moisture plume from the sub-tropical
    Pacific and Western Gulf over-tops the entire length of the
    frontal zone through the Ohio River Valley, however, only
    remarkable remaining unstable air is upstream near the sources
    across much of Texas.  As such, RADAR mosaic depicts remaining
    strongest thunderstorms along the front in the Heart of Texas,
    with a few more scattered cells into Deep South Texas as well.
    Downstream across the Ozark Plateau into the Lower Ohio River
    Valley, a broad shield of moderate rainfall still exists, mostly
    providing more beneficial, lower intensity rainfall which becomes
    even lighter across Ohio into the St. Lawrence Valley at the far
    extremity of the stationary front.

    The front will remain relatively stationary with a continued slow
    southeastward drift across eastern into southeastern Texas with
    the string of weak surface waves remaining dotted along it through
    the Lower Mississippi Valley through Tennessee/Kentucky and
    through the Northeast.  The reduced moisture and faster moving
    northern stream flow will further diminish the risk of heavy
    rainfall across the northern portion of the front keeping the
    greater risk of intense thunderstorms generally limited to Texas
    and far southeast Oklahoma/southwest Arkansas.  Rainfall rates of
    1-2"/hr and spots of 2-4" will remain across this area of stronger
    thunderstorms and as such WPC has retained a Slight Risk of
    Excessive Rainfall (level 2 of 4) for much of central Texas into
    southeast Oklahoma.  The plume of moisture and risk of
    thunderstorms will continue through the weekend but continue to
    slowly shift eastward into the Southeast.
    
    This will be the last Storm Summary issued by the Weather
    Prediction Center for this event. Please refer to your local
    National Weather service office for additional information.

    The slow-moving cold front will continue to focus showers and
    thunderstorms from South Texas through the Mississippi Valley and
    into the Great Lakes tonight. Over southern and central Texas, the
    front is expected to stall as a strengthening low-level jet feeds
    deep Gulf moisture into the region, supporting repeated rounds of
    thunderstorms with rainfall rates of 1 to 3 inches per hour from
    the Hill Country and the I-35 corridor, including the Austin and
    San Antonio metro areas, to South Texas and the Rio Grande.
    Additional rainfall of 3 to 6 inches with locally higher amounts
    is possible tonight, followed by another 1 to 3 inches on Friday
    over areas already saturated by heavy rain. A Moderate (level 3 of
    4) of Excessive Rainfall is in effect tonight for portions of
    southern and central Texas, with a broader slight risk (level 2 of
    4) extending from Texas to Wisconsin. On Friday, a Slight Risk
    remains in place from South Texas northward into the Dallas-Fort
    Worth metro area. Farther north, the front will push east through
    the Ohio Valley on Friday, bringing the heavy rain threat to an
    end across the central Plains and Midwest, although river flooding
    will continue in many areas. The front is expected to reach the
    Southeast and Gulf Coast on Saturday, shifting the threat of heavy
    rainfall into those regions this weekend.
    
    The next Storm Summary will be issued by the Weather Prediction
    Center at 900 AM MDT. Please refer to your local National Weather
    Service office for additional information on this event.

    At 800 AM MDT...The main surface low associated with the larger
    storm is currently analyzed over southwest Kansas with a central
    pressure of 1004 mb (29.65 in Hg). From the surface low, a
    stationary front extends northeastward across central Kansas, and
    through southern and eastern Iowa to a secondary weaker surface
    low.  A cold front extends southward from the surface low in
    Kansas along 100W before extending westward toward the Lower Pecos
    River.  RADAR mosaic shows strong thunderstorms with heavy
    rainfall along and in advance of the cold front with Hill country
    activity closer to the front and weakening convective line across
    North Texas before becoming more stratiform across eastern
    Oklahoma.  The stratiform showers become more broken and smaller
    in areal coverage across eastern Kansas, northern Missouri before
    broadening into a shield across eastern Iowa, Wisconsin and
    northern Illinois.

    The surface low is expected to slowly shift eastward and weaken as
    a strong high pressure builds in from the north.  In doing so, the
    frontal zone will begin to orient more south-southwest to
    northeast from the central Texas Rio Grande through Oklahoma and
    Kansas and through Missouri into Illinois to southern LP of
    Michigan as the strong ridge of high pressure over the southeast
    holds strong.  This allows for strong, moist and unstable return
    moisture flow from the western Gulf and subtropical Pacific to
    align through the depth of the atmosphere while providing a
    repeating/training environment for thunderstorms that develop
    today. Greatest instability and moisture availability will be
    across portions of TX into Kansas where greater coverage of heavy
    rainfall producing thunderstorms will have the potential intense
    rain rates of 1-3"/hr with broad area of 2-4" across much of
    southern to northeast TX and southeast Oklahoma, with embedded
    higher totals 6+" likely. As such a Moderate Risk of Excessive
    Rainfall is in place aligned with flood watches across Texas into
    far southeast Oklahoma.  Further north across Kansas into
    Missouri, reduced instability but solid convergence should support
    strong thunderstorms but may be a bit more scattered in nature
    relative to further south.  Still a broad Slight Risk remains in
    place across all of southern Kansas across Missouri and downstream
    into Northern Illinois.   As such, incidents of flash flooding and
    river flooding are likely across the areas of concern but will be
    reducing in areal coverage and magnitude into Friday, becoming
    more limited to Texas, Lower Mississippi/Ohio River Valleys and
    the central Gulf coastal states.
    
    The next Storm Summary will be issued by the Weather Prediction
    Center at 900 PM MDT. Please refer to your local National Weather
    Service office for additional information on this event.

    At 800 PM MDT...A surface low has developed and tracked into the
    Central Plains, now stationed over southwestern Kansas with a
    central pressure of 1000 mb(29.53 in Hg). At the surface, a
    stationary front is analyzed from the southern Plains extending to
    the northern Plains. In addition, a warm front was analyze
    extending from southwest Kansas into northeastern Oklahoma and a
    cold front moving east extending from southwest Kansas to West
    Texas. Dew points ahead of the cold front are well into the mid
    60s to low 70s, providing ample moisture for heavy rainfall for
    flash flooding. NWS radar shows a large swath of moderate to heavy
    lines of thunderstorms developing across the Southern and Central
    Plains. Stratiform rainfall with embedded isolated thunderstorms
    are also occurring over northeastern Nebraska, Iowa, and Eastern
    Colorado.

    Flash flooding, some of which could be significant, is likely
    tonight into the overnight hours across western Texas and Oklahoma
    as thunderstorms form in an unstable, moist environment ahead of a
    frontal boundary. Flooding impacts will be amplified where storm
    training occurs. Closer to the surface low, a broad stratiform
    precipitation shield may bring a couple of inches of rain across
    eastern Colorado and New Mexico where saturated grounds from
    previous rainfall could increase water runoff and flooding.
    Lastly, the surface low lifting northwards towards will transport
    anomalously moist environment where heavy downpours are likely.
    Rainfall accumulations of 2-6 inches with isolated higher amounts
    are possible across much of Texas where storms training occurs.
    Tomorrow, a Moderate Risk of Excessive Rainfall continues for
    parts of the Central and Southern Plains, but the greatest flash
    flood risk will remain across Texas and southern Oklahoma where
    the front stalls and interacts with the highest instability.
    
    The next Storm Summary will be issued by the Weather Prediction
    Center at 900 AM MDT. Please refer to your local National Weather
    Service office for additional information on this event.

    Flash flooding, some of which could be significant, is likely this
    afternoon across western Texas into Oklahoma as thunderstorms form
    in a unstable, moist environment ahead of a quasi-statioanry
    frontal boundary. Flooding impacts will be exacerbated where storm
    training occurs. Closer to the upper-level low and forming surface
    low, a broad precipitation shield may bring a couple of inches of
    rain to the Sangre de Cristo and San Juan mountain ranges of
    Colorado and New Mexico where wet antecedent conditions could
    enhance water runoff and flooding. Lastly, the surface low lifting
    northwards towards the Central Plains will advect an anomalously
    moist environment towards northern Kansas, southern Nebraska, and
    western Iowa. Rainfall accumulations of 2-4 inches with isolated
    streaks of 4-6 inches are possible where the storms train.This
    will bring flash flooding concerns, as well as creek and stream
    flooding. Tomorrow, a Slight Risk of Excessive Rainfall continues
    along the intersection of the front and surface low in the Central
    Plains and Midwest, but the greatest flash flood risk will remain
    across Texas and southern Oklahoma where the front stalls and
    interacts with the highest instability.
    
    The next Storm Summary will be issued by the Weather Prediction
    Center at 900 PM MDT. Please refer to your local National Weather
    Service office for additional information on this event.

    At 800 PM MDT...The center of the remnants of Polo is located just
    to the south of the New Mexico-Mexico border and continues to move
    northeast at 23 mph. Moisture associated with Polo continues
    stream northward across the Southwest. In addition, a strong
    upper-level trough is digging into the Southwest U.S., providing
    upper-level divergence and enhancing tropical moisture transport
    from Polo. Rounds of locally heavy thunderstorms with hourly
    rainfall rates of 1-2 in per hour are streaming south to north
    across Arizona, New Mexico and west Texas with ongoing flash
    flooding. Showers and embedded thunderstorms stretch across the

    Flash flooding, some of which could be significant, is likely
    overnight across much of Arizona, New Mexico, western Texas,
    southern Utah, and southern Colorado. Tropical moisture streaming
    ahead of the remnants of Polo, combined with an amplified
    upper-level trough, will support numerous rounds of showers and
    thunderstorms capable of producing heavy rainfall. The remnants of
    Polo is forecast to move northward towards New Mexico and West
    Texas overnight. This will bring another surge of tropical
    moisture and intense rainfall rates capable of producing locally
    significant flash flooding, particularly over sensitive terrain
    such as burn scars and arroyos. Tomorrow, the remnants of Polo is
    forecast to be absorbed into a forming surface low over the
    Plains. Thunderstorms will then initiate in the Plains and bring a
    risk of flash flooding and riverine flooding. West Texas into
    Oklahoma have a targeted Moderate Risk of excessive rainfall as a
    result of greater potential for training storms with embedded
    intense rainfall rates. Additionally, northern New Mexico and
    southern Colorado may see a greater likelihood of flash flooding
    near the comma-head of the forming mid-latitude cyclone.
    
    The next Storm Summary will be issued by the Weather Prediction
    Center at 900 AM MDT. Please refer to your local National Weather
    Service office for additional information on this event.
