Flash floods are still a possibility in the South US, and rain has soaked 40 states.
As the jet stream shifts from west to east, a zonal flow pattern moves in and swiftly directs storms across the Lower 48.
Flash Flood, Warm Temps
According to FOX Weather analyst Britta Merwin, certain regions-like the middle Plains-need rain, while other areas may have received too much of it. Between 3 and 5 inches of rain are expected to fall, according to the FOX Forecast Center, across parts of Texas, Oklahoma, northeastern Wyoming, South Dakota, and southeastern Montana.
The weather will warm up south of the jet stream, much like it does in the summer.
The FOX Forecast Center predicted that this week's highs throughout a large portion of the central and southern US will range from the middle to upper 80s, which is roughly 10 to 20 degrees warmer than typical for this time of year.
Tuesday Scattered Showers and Storms
Most of the Plains, as well as portions of the Southeast and mid-Atlantic, are forecast to experience scattered showers and storms.
The FOX Forecast Center predicts that southeast Texas, particularly the Houston metro region, where flash flooding is a major worry, would likely receive the highest rainfall.
Wednesday
On Wednesday, the top levels of the atmosphere's low-pressure system will inject enough instability to increase the possibility of severe weather across portions of eastern Colorado and southeastern Wyoming. According to Weather & Radar, isolated severe storms along the dry line might potentially occur in parts of West Texas, which stretches from Amarillo all the way south near Del Rio.
Every day, the rain will continue to have an impact on those areas, and flash floods from eastern Texas and Oklahoma into western Arkansas and Louisiana are likely.
The Houston metro area and southeastern Texas could once more experience the highest risk of flash flooding.
Thursday
Again, a sizable portion of the Plains, Mississippi Valley, and Southeast are predicted to experience showers and storms.
A more structured storm system, on the other hand, will move slowly across the northern Rockies along with the northern Plains while dropping a lot of rain.
The FOX Forecast Center predicts that this could cause 3 to 5 inches of rain to fall over locations that are not accustomed to receiving this much rain in such a short period of time.
Therefore, regions of eastern Wyoming, eastern Montana, the western Dakotas, and western Nebraska will provide the greatest risk of flash flooding.
From Wednesday evening until late Friday night, the National Weather Service has issued multiple Flood Watches for eastern Montana and portions of northeastern Wyoming.

Friday
On Friday and into the weekend, the last disturbance will settle across the Southwest and Mexico.
According to the FOX Forecast Center, there is a strong signal for potentially heavy rainfall of several inches on top of what has already fallen by that time. Deep moisture from the Gulf of Mexico will be driven north into the southern Plains.
Multiple bouts of moderate to locally heavy rainfall are more possible, which increases the risk of more flash flooding due to the increasingly saturated ground, FOX Weather reports.
