This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

Isolated light rain showers will gradually dissipate early this
morning over the mountains and plains. Scattered thunderstorms
will redevelop by early this afternoon over the mountains and
spread over the plains during the late afternoon and evening

A few storms may become severe with large hail up to 2
inches in diameter, winds gusts to 60 mph and heavy rain. The best
chance for the stronger storms will be along and east of a line
from Limon to Grover. Showers and thunderstorms will gradually
diminish later tonight. An upper level disturbance and cold front
will enhance thunderstorm activity this evening.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Thunderstorm chances will gradually decrease during the latter
half of the week as drier air spreads in from the west. Over the
weekend, a return to a moist southwesterly flow will increase
the chance for storms and wetting rainfall starting in the high
country, and then over most of the outlook area by Monday. The
chance for severe weather appears low, however as humidities
increase, some areas could see locally heavy rainfall by early
next week.


Spotter activation may be needed across the plains of Northeast
Colorado after 3 pm.
