…RED FLAG WARNING HIGH MOUNTAIN VALLEYS…
…SEVERE THUNDERSTORM THREAT OVER THE PLAINS…
This hazardous weather outlook is for northeast and north central
Colorado.
.DAY ONE…Today and Tonight
A few severe thunderstorms are expected on the plains of eastern
Colorado in the late afternoon and early evening hours. The
highest chance of severe storms will be along and east of a line
from Cheyenne Wyoming to Greeley, Byers, and Kiowa. Destructive
hail greater than 2 inches in diameter and damaging winds to
around 70 mph will be possible from the strongest storms. There is
a smaller threat of severe weather west of that line including
the I-25 Corridor. Most of the storms along and west of I-25 will
produce gusty winds to around 45 mph and only a brief period of
rain.
Fire danger will be higher in the mountains and over the higher
foothills as winds increase. Red Flag Warnings are in effect until
8 PM today for the high mountain valleys where the combination of
strongest winds and lowest humidities can be expected. Thunderstorms
producing lightning but little if any rain may produce new fire
starts. Be sure to adhere to local fire bans.
.DAYS TWO THROUGH SEVEN…Saturday through Thursday
Fire weather concerns will continue through the weekend as dry
humidity and gusty winds are expected over the higher terrain as
well as over the northern urban corridor. Mostly dry weather is
expected on Saturday with only a few gusty thunderstorms possible
across the far eastern plains. Dry and warmer weather is expected
Sunday and Monday, with a better chance for showers and storms by
Tuesday.
.SPOTTER INFORMATION STATEMENT…
Formal spotter activation is not anticipated today, but reports of
observed severe weather will be appreciated.
