Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1050 AM CDT Mon Jun 20 2022

Valid 201700Z - 211200Z

An Elevated risk area is introduced for portions of northeast CO and
adjacent states. Morning surface observations show RH already
falling into the 30-35% range across the northeastern CO plains with
winds between 15-25 mph. Although persistent high cloud cover is
expected through the day, morning guidance suggests that the
probability for RH reductions into the 10-20% range is fairly high,
especially in the foothills. Likewise, winds will increase through
the afternoon as zonal flow over the central Rockies increases,
resulting in elevated to locally critical fire weather conditions.
While some locations have received light rainfall over the past 24
hours, MRMS and AHPS rainfall estimates and CoCoRaHS measurements
show most of the region remains dry east of the foothills with ERC
values estimated to be above the 90th percentile for mid June.
Similar fire weather conditions are likely to the north and east
across adjacent areas of WY, NE, and KS, but recent wetting rainfall
and/or more marginal fuel status limits the risk area.

.PREV DISCUSSION... /ISSUED 0152 AM CDT Mon Jun 20 2022/

...Synopsis...
The trough within the Great Basin and northern Rockies will continue
east and eject into the central/northern Plains later today. A
surface trough in the northern Plains into the central High Plains
will remain moderately strong. In the Northwest, high pressure will
build at the surface.

...Central High Plains...
Some potential for locally elevated conditions will exist during the
afternoon. The surface high building west of the Divide and the
surface trough to the east, aided by the strong mid-level winds,
will drive strong downslope flow in the lee of the Rockies from
eastern Wyoming into parts of central Colorado. 15-25 mph winds are
possible in this region, particularly in parts of southeastern
Wyoming where the mid-level jet will be during the afternoon. RH of
10-15% is possible within the foothills with values closer to 20%
away from the terrain. Given current fuel reports from these areas
and some light rain observed in southeast Wyoming on Sunday
afternoon, no highlights will be added.
