Meteorologist Max Schuster is warning that the remnants of Hurricane Polo have been absorbed into a powerful upper-level storm, creating a surge of tropical moisture that could keep producing dangerous flooding across parts of the central United States before the system shifts east and a sharp cold front changes the weather pattern.
In a forecast from Max Velocity – Severe Weather Center, Schuster said the storm has access to an unusually large amount of moisture for this time of year, with some of the hardest-hit areas already dealing with saturated ground. Texas remains one of the biggest concerns going into Thursday, October 1, while additional rain and thunderstorms could linger into Friday and the weekend.
“The remnants of Hurricane Polo are fueling a massive storm,” Schuster said, describing a setup capable of producing both flash flooding and renewed severe weather before cooler, drier air eventually pushes farther south.
Texas Faces Another Round Of Heavy Rain
Schuster said one of the most concerning areas on Thursday will stretch along the Interstate 35 corridor from Dallas toward San Antonio and Killeen, where an elevated threat of excessive rainfall remains in place.
The main problem is not simply how much rain falls over an entire day, but how quickly it can come down.
Schuster said some thunderstorms could produce rainfall rates of roughly 1 to 3 inches per hour, meaning locations that spend much of the day dry could still run into flooding problems if a slow-moving band settles overhead for several hours.
Dallas and Fort Worth are among the areas he is watching closely.
Some model guidance was less aggressive around the metro area, but Schuster said other projections showed several inches of rain, with localized totals potentially climbing past 6 inches if storms repeatedly move over the same locations.
He also highlighted areas farther north and west, including parts of Oklahoma and the southern Plains, where the ground has already taken on substantial moisture.
That combination matters. Heavy rain is dangerous on its own, but when soils and drainage systems have already absorbed repeated rounds of water, it takes less additional rainfall to turn a troublesome situation into a flash-flood emergency.
Flood Threat Does Not End Immediately
Schuster said the overall risk should begin easing somewhat by Friday and Saturday, but he does not expect the moisture to disappear all at once.
Texas could continue seeing scattered showers and thunderstorms, with enough tropical moisture hanging around to create additional flooding issues in spots that have already received heavy rainfall.
Farther north, Schuster pointed to a broad corridor from Kansas and Missouri into Iowa and Illinois where several inches of rain could accumulate by the time the storm is finished.
He said areas near Des Moines, Kansas City, Topeka and Maryville could see widespread totals in the 3-to-6-inch range, with isolated pockets reaching 8 to 10 inches.
A wider area stretching toward Chicago and Milwaukee could receive roughly 1 to 3 inches.
The wide reach of the system is one of the more notable parts of the forecast. This is not a compact storm affecting one state or one metropolitan area; moisture tied to a former hurricane is being pulled into a larger upper-level circulation, allowing the impacts to spread across a large portion of the country.
Tropical Moisture Could Keep Storm Alive Into Weekend
Schuster said the storm may continue evolving through the weekend rather than simply fading over the Plains.
Because the original moisture source came from a hurricane, the atmosphere contains what he described as an “absolutely unbelievable amount of moisture” for early October.
As the system slowly moves east, he said it could redevelop or strengthen somewhat closer to the East Coast on Saturday and Sunday.
That does not necessarily mean every area east of the Rockies will experience severe conditions, but Schuster said the storm will continue affecting a large part of the country before it finally moves out.
The biggest immediate flooding danger remains focused farther west, especially in Texas and parts of the central Plains, but the weekend evolution is worth watching because the same broad disturbance will still be present.
Schuster also noted the possibility of continued rainfall in southeastern Colorado and nearby areas, where the circulation around the low pressure system could support very large localized totals.
Some projections showed extreme amounts in that region, including the possibility of more than a foot of rain in isolated locations northeast of Trinidad.
A Strong Cold Front Pushes South
After the heavy rain and tropical moisture, Schuster said the next major change will come from a strong cold front dropping through the central United States.
Thursday will still be warm across much of the Southeast, with many locations in the 80s, but cooler air will spread south and east behind the front.
By Friday morning, lows are expected to fall into the 30s and 40s across portions of the northern Plains.
Schuster described a sharper temperature divide developing around Missouri and central Indiana, where some areas will remain relatively mild while locations behind the boundary settle into much cooler conditions.
The front should continue progressing south into Saturday, reaching closer to northern Tennessee and northeastern Arkansas.
North of that dividing line, Schuster expects much cooler and drier air.
That should come as welcome relief for areas that have spent days under muggy, stormy conditions, although the break may not last particularly long.
Another System May Develop By Sunday
Schuster said a new disturbance may begin taking shape over the weekend, allowing warmer and more humid air to return northward.
By Sunday, highs could rebound into the 70s across many areas that turn cooler behind the first front.
The warming trend may continue into Monday, although Schuster still expects relatively pleasant mornings across parts of the southern Plains and lower Mississippi Valley.
That quick rebound is typical of the kind of changeable early-fall pattern he has been describing, where strong fronts temporarily sweep away humidity before the next system starts drawing warm air back north.
It also means the cooler weekend weather should not necessarily be viewed as the beginning of a permanent seasonal shift.
Instead, the country may continue swinging between storm systems, warm moisture surges and colder pushes from the north.
Schuster Says The Setup Demands Attention
Schuster repeatedly emphasized that flooding is the central concern as the remnants of Polo continue interacting with the larger storm.
The danger comes from several ingredients lining up at once: deep tropical moisture, slow-moving thunderstorms, already-wet ground and a large upper-level low capable of keeping rain around for an extended period.
Even where forecast totals appear modest, he said localized bands could produce much higher amounts than models suggest.
That uncertainty is especially important around urban areas such as Dallas-Fort Worth, where a few hours of extreme rainfall can create serious problems even if neighboring communities receive much less.
Schuster’s forecast also shows why hurricane remnants can remain dangerous long after the organized tropical system itself is gone.
Polo is no longer behaving like a conventional hurricane, but its leftover moisture has become fuel for a much larger weather system, one capable of affecting locations hundreds of miles away from the storm’s original path.
By Friday and into the weekend, the focus should gradually begin shifting from the heaviest flooding toward cooler temperatures and the storm’s movement farther east.
Until then, Schuster said areas in Texas and the central United States remain under the greatest pressure from a system carrying an extraordinary amount of moisture into the opening days of October.
