This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

Showers and thunderstorms will develop across the area this
afternoon and evening. The storms will develop near the foothills
by noon, then across the I 25 corridor through 3 pm, then east
across the northeast plains the rest of the afternoon and evening.

There will be a slight risk of severe thunderstorms over the
northeast plains this afternoon and evening. Large hail up to 2
inches and damaging wind in excess of 60 mph will be the main
threats. The greatest severe threat will be along and east of a
line from around Greeley to Byers to Monument. Locally heavy
rainfall could produce urban and small stream flooding as well.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Tuesday will be another active day with plentiful thunderstorm
activity. The threat of severe weather will be lower there, with a
marginal risk of hail and damaging winds mainly on the plains
south of Interstate 70. Once again, some of the storms may produce
heavy rainfall but the threat of flooding looks lower.

Wednesday and Thursday will see less thunderstorm activity. There
may be a small threat of severe storms near the eastern border
Thursday evening. For Friday and the weekend, storms will increase
again and there will be a risk of severe storms.


Spotter activation may be needed after 1 pm this afternoon.
