This hazardous weather outlook is for northeast and north central
Colorado.

.DAY ONE...This Afternoon and Tonight

Another hot afternoon on tap with highs in the 90s across the
urban corridor and northeast plains. Thunderstorms will form over
the higher terrain by midday, increase in coverage and spread
eastward after 2 pm and continue through this evening. The
stronger storms will likely produce frequent lightning, 1 to 2
inches of rain in one hour, small hail, wind gusts to 40 mph along
with minor urban and small stream flooding.

There is a marginal risk of severe thunderstorms north and east of
Sterling. The main risk there will be hail up to one inch in
diameter and wind gusts to 60 mph. Heavy rainfall could also
result in localized flash flooding.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

There will be a chance of afternoon and evening thunderstorms on
Tuesday. A few thunderstorms could be severe over the far
northeast plains. Otherwise storms will produce lightning, gusty
winds to 50 mph, small hail and brief heavy rain.

A weather system to the north will increase winds across the area
on Wednesday, increasing fire weather concerns as temperatures
get hotter and humidity drier. Thunderstorm activty will decrease
on Wednesday with only isolated activity for Thursday and Friday,
if any at all. Temperatures will remain hot through the period.
Readings across the plains will be in the upper 90`s to lower
100`s for Thursday and Friday.

A return of moisture for the weekend will bring scattered afternoon
and evening thunderstorms again to the region.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight. Rainfall
reports however would be greatly appreciated.
