This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

Scattered to isolated thunderstorms are expected to move across
the area this afternoon and evening. Some storms may become
severe over and east of Logan and Washington counties where golf
ball size hail and wind gusts to 80 mph will be possible.
Elsewhere, storms are expected to be weaker with brief heavy
rain, small hail, and wind gusts to 40 mph.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Afternoon and evening thunderstorms will be possible through
Tuesday of next week, with the best chance of storms in the high
country, over the Palmer Divide and the northeast corner of the
state. A few storms on the far northeast plains could turn severe
late on Monday and Tuesday, with large hail and damaging wind
gusts the main weather threats. Drier and slightly warmer weather
is expected for the latter half of the week as a large high
pressure ridge slowly builds in from the west.
