...SEVERE WEATHER EXPECTED AGAIN FOR THE PLAINS THIS AFTERNOON AND
EVENING...

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

.DAY ONE...Today and Tonight

Another round of strong to severe thunderstorms is likely this
afternoon and evening across the plains. Look for scattered
thunderstorms to develop across the higher terrain, including the
Foothills, Palmer Divide, and Cheyenne Ridge area by early
afternoon. Those storms will develop and move east across the
plains late this afternoon and evening. Large hail up to 2 inches
in diameter, damaging winds of 60 mph or more, and even a couple
tornadoes will be possible from the stronger storms. Heavy rain
will also be an impact, causing localized flooding problems over
urban areas with poor drainage, low lying areas, and potentially
over southeastern Weld County into northwesterly Morgan County
where 4 to 6 inches of rain fell last night.

Storms are expected to decrease from west to east across the
plains later this evening, though we could still see a few storms
last through midnight.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Drier weather will return for Wednesday through Saturday with
only a slight chance of thunderstorms in the afternoon and
evening. A weather system may affect the area by Sunday bringing
a better chance of thunderstorms.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be required by 2 PM.
