From now into early next week, you could say the atmosphere has shifted into reverse gear.
Typically, weather systems move from west to east in the United States and the rest of the Northern Hemisphere. This will not be the case over the next couple of days, as we track an area of low pressure, which originated from the Northeast, moving in the reverse direction. The low, which is currently over the Great Plains, is making it's way toward the Desert Southwest. While, it's not unheard of to see a weather system move east to west in the United States, but it's certainly not common.
This is the second odd weather pattern this month. Over the Fourth of July holiday weekend, an area of low pressure in the upper atmosphere got stuck over the South and brought daily bouts of showers and thunderstorms that caused flooding from the Gulf Coast to the Appalachians and Ohio Valley.
Next, let's dig into the potential benefits and possible dangers from this latest strange weather pattern.
Drought Relief in the Plains?
Monday, as the "reverse low" moves further west, widely scattered showers and thunderstorms with locally heavy rainfall, can be expected in parts of the Southeast. A typical type weather pattern for July. Even so, most of the Southeast will see lots of sunshine and temperatures rising into the upper 80's.

Through the middle part of the week ahead, we will see a beneficial aspect of this weather system in the southern Plains and Southwest. The upper low will provide the necessary lift in the atmosphere to produce numerous showers and thunderstorms from Texas and Oklahoma to New Mexico and adjacent parts of Arizona, Colorado and Kansas.
That said, if any one location sees too much rainfall too fast, we could see some pockets of flash flooding develop.
Current forecast guidance shows the potential for an inch or more of rainfall across a wide area in parts of Oklahoma, northern/western/central Texas and New Mexico. Heavier amounts of 3 to 4 inches are possible in an area between Midland, Lubbock and Abilene, TX.
Increased rainfall chances won't be the only result of this odd weather pattern, temperatures will also take a tumble in the southern Plains. Instead of highs in the upper 90s and low 100s seen as rencely and Saturday, temperatures drop into the 70s and 80s in some locations.
