Rain and storm chances are in the forecast for parts of the Desert SW with a cutoff low nearby and remnants of Alvin pushing northward! Heavy rain has already lead to isolated instances of flooding around Arizona, where some places have surpassed 2 inches of rain! So much rain fell in Phoenix to SHATTER the previous daily record. Of course, with so much rainfall, the flooding threat will need to be monitored.
This is sorely needed rainfall, though. Let's check out the drought monitor below and you will notice lots of Level 4 and 5 drought across southern California, New Mexico, and Arizona.
Today and tomorrow's rain chances will be highest as the cutoff low will be pushed eastward into the Plains. Some of the storms could be severe in Colorado and New Mexico, producing large hail and damaging winds.
The stronger storms will favor the afternoons - be weary of blowing dust in the vicinity of any stronger thunderstorm this afternoon.
This serves as a good reminder: monsoon season begins in less than 2 weeks.
