This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

Scattered to numerous thunderstorms are expected to move across
the area this afternoon and evening as monsoon moisture continues
to stream over the state. Heavy rain, wind gusts to 40 mph, and
cloud to ground lightning are the main threats with the
thunderstorms. Slow moving storms will have the potential to
produce a quick inch of rain in a very short time, which could
lead to localized flooding.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

There is a continued chance for showers and thunderstorms on
Saturday with the passage of an upper level weather disturbance.
A few storms on the plains could produce up to a half inch of
rain in 30 minutes. Otherwise rainfall amounts should be on the
light side, and severe weather is not anticipated. A return to
drier and warmer weather Sunday through Tuesday will give way to
an increase chance for thunderstorms, particularly in the high
country Wednesday and Thursday with the monsoon moisture plume
returning to the region.


Spotter activation is not expected to be needed today or tonight.
