central...south central and southeast Colorado.
.DAY ONE...Today and Tonight
Strong to severe thunderstorms are forecast for this afternoon and
evening across the Eastern Mountains, into the Interstate 25
corridor. The strongest storms will be capable of 1.5 inch diameter
hail, damaging wind gusts near 60 mph and locally heavy rainfall.
For areas of the Continental Divide and San Luis Valley, more
generally thunderstorms are forecast, with small hail to the size of
dimes and wind gusts to near 50 mph. For areas east of Interstate
25, much will depend on clearing and whether thunderstorms can
develop late this afternoon.
.DAYS TWO THROUGH SEVEN...Sunday through Friday
Daily afternoon and evening showers and thunderstorms are expected
Sunday through Friday. The best chances for storm activity will be
found across the mountains and high valleys Sunday through Tuesday,
then will become more widespread and include the eastern plains
starting Wednesday. The primary threat from any of the stronger
storms will be gusty outflow winds nearing 60 mph. Otherwise, the
most likely hazards with any organized storms will be gusty outflow
winds around 40 mph, small hail, frequent cloud to ground lightning,
and brief periods of moderate to heavy rain.
.SPOTTER INFORMATION STATEMENT...
Weather conditions that meet reporting criteria for spotters will

This hazardous weather outlook is for northeast and north central
Colorado.
.DAY ONE...Today and Tonight
Scattered to numerous thunderstorms are expected to develop this
afternoon behind a cold front, with heavy rainfall and damaging
winds being of greatest concern, and an isolated threat of large
hail in the stronger, more organized storms. The greatest
moisture is expected over the north central and northeastern
portion of the forecast area (generally north of I-70) where dew
points are already in the mid 50s this morning, and expected to
increase behind the approaching cold front, where dew points are
currently in the 60s. Forecast soundings indicate PWATs increasing
to ~ 1", bringing them to between 100-130% of normal through
tonight across the far northeast corner, with a decreasing
gradient towards the foothills. There is less certainty with how
far west the higher moisture makes it, but there is potential for
the heavy rainfall to make it as far west as the urban corridor.
The heaviest rainfall threat is expected to diminish from west to
east, with showers and thunderstorms sticking around through late
tonight.
.DAYS TWO THROUGH SEVEN...Saturday through Thursday
Scattered afternoon thunderstorms are expected on Saturday and
Sunday over the higher terrain, with some capable of spilling onto
the plains on Saturday. More of the same will be in store into
next week, with temperatures expected to remain in the 90s for the
first half of next week, and a short reprieve by mid-week, when
high temperatures will be in the 70s/80s for the lower elevations
as widespread showers and storms will return to the forecast area.
.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed today or tonight, but any
observations of severe hail/wind or heavy rainfall reports will be
appreciated.
