This hazardous weather outlook is for northeast and north central
Colorado.
.DAY ONE…Today and Tonight
Showers and thunderstorms are expected over the mountains by
early afternoon and spread over the plains through the afternoon
and evening hours. The main impacts will be heavy rain with the
potential for localized flooding, especially over fire burn
scars. Rainfall rates up to 2 inches in less than one hour are
possible with the stronger storms. Further east, there is also a
marginal threat of severe thunderstorms through the evening, with
hail of one inch in diameter and damaging winds to 60 mph.
Showers and thunderstorms will gradually diminish later this
evening and overnight.
The airmass over northern Colorado is quite moist today along
with light winds aloft, which will lead to slower moving
thunderstorm activity and the locally heavy rainfall. The
thunderstorms with heavy rain are expected to be moving over the
I-25 through the early and mid-afternoon. Late afternoon and
evening should see thunderstorm activity shifting out to the
northeastern plains.
.DAYS TWO THROUGH SEVEN…Friday through Wednesday
Storm coverage is expected to decrease Friday, but a couple
strong to severe storms will still be possible over the eastern
plains, roughly along and south of the I-76 Corridor.
Higher moisture levels will then likely return for the weekend
with more numerous showers and thunderstorms. There will be a
threat for locally heavy rainfall and a couple severe storms on
the plains and Palmer Divide each afternoon and evening as well.
Monday could still see higher storm coverage, before drier air
builds into the region for Tuesday and Wednesday. However, enough
moisture will still be available for a few afternoon and early
evening thunderstorms.
.SPOTTER INFORMATION STATEMENT…
Spotter activation will not be needed today or tonight. However,
heavy rainfall reports will be appreciated.
