This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.
.DAY ONE...Today and Tonight
Critical Fire Weather conditions will return to southern portions
of the southeast Colorado Plains and San Luis Valley today. Gusty
winds, low humidity and dry fuels will lead to the possibility of
rapid rates of fire spread.
Snow will spread into the Continental Divide and Pikes Peak
region today with accumulations of 2 to 5 inches falling primarily
during the afternoon hours. This may cause slick and snow covered
roads across the mountains, with slushy conditions during the
intense snowfall rates across the Palmer Divide. Snow will end
this evening.
A strong cold front will bring cooler conditions with higher
humidity to the remainder of southern Colorado today. North winds
could gust up to 50 mph at times.
Subfreezing temperatures will spread across southern Colorado
tonight with a hard freeze likely across the southeast plains
where the recent warmth has led to an unusually early start to the
growing season. Protect pipes and tender vegetation.
.DAYS TWO THROUGH SEVEN...Saturday through Thursday
Sub freezing temperatures will be possible again Saturday night
and Sunday across the southeast plains. Warmer weather returns
through the mid to latter part of next week with isolated showers
possible over the mountain areas beginning Monday. Stronger winds
and critical fire weather conditions will be possible Wednesday
and Thursday as the next storm system approaches from the west.
.SPOTTER INFORMATION STATEMENT...
Weather conditions that meet reporting criteria for spotters will
be likely over portions of the region.
