This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

Isolated thunderstorms are expected this afternoon and evening,
mainly over the plains. A few storms could become severe over the
Palmer Divide region by mid afternoon with damaging wind gusts
to 60 mph and hail up to one inch in diameter. Temperatures will
be slightly cooler today.

An approaching upper level disturbance and cold front will bring
a better chance of showers and thunderstorms tonight over the east
slopes and northeast plains.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

The chance for showers and thunderstorms will increase on Friday
with a weak storm system moving across the state. The showery
upslope precipitation east of the mountains will be accompanied
by noticeably cooler temperatures. Precipitation amounts should
be on the light side. Over the weekend, storm chances will
decrease with a high pressure ridge building in from the Desert
Southwest. Look for a slight uptick in thunderstorm activity and a
slight dip in temperatures on Monday with another weak upper air
disturbance passing over the area. Warmer and drier weather will
then return to the outlook area for Independence Day and Wednesday
beneath a strong ridge of high pressure.


Spotter activation may be required across Elbert, Lincoln, and
southern Washington counties after 2 pm this afternoon.
