Drought-helping rain in the central U.S. this week will get a boost from the remnant moisture and energy of former Eastern Pacific Hurricane Norma.
No – a hurricane is not coming to the Lower 48 anytime soon.
Instead, some deeper tropical moisture will be pulled northward into the region along with some leftover spin provided by Norma itself.
Norma hit Mexico's southern Baja California Peninsula on Saturday as a Category 1 hurricane. It's remnants have since moved inland.
An upper-level low-pressure system that's digging into the Southwest early this week will help pull Norma's moisture, as well as moisture from the Gulf of Mexico, northward through the Plains and upper Midwest.
Parts of West Texas and Oklahoma stand the best chance at some elevated rainfall totals. Two to perhaps five inches of rain could fall in this zone. More than an inch of rain is likely from southwest Texas to the upper-Mississippi Valley through Thursday.
And this may not be the end of the wetter weather. Computer model guidance suggests that disturbed weather could continue into the following week, but those details will need to be figured out in the coming days.
The rainfall should be beneficial for most spots. Moderate or worse drought continues in pockets from Texas to Minnesota and Wisconsin. Some in this swath are experiencing a 6 to 12-inch deficit so far this year.
That said, if too much rain falls too quickly then we can't rule out some localized flash flooding.
