Day 1 Fire Weather Outlook

1050 AM CDT Wed Sep 14 2022
Valid 141700Z - 151200Z
...NO CRITICAL AREAS...
The previous forecast remains on track. The latest guidance
consensus suggests that a couple of hours of widespread Elevated
conditions may occur across western Nebraska into far northwest
Kansas. However, clouds and occasional showers will continue to
overspread the central Plains through the day, with potentially
heavier rains possible through Day 2/tomorrow. As such, significant
wildfire-spread potential should be somewhat limited, precluding the
addition of any fire weather highlights.

...Synopsis...
A large-scale ridge will remain centered over the MS Valley, while
broad midlevel troughing and enhanced west-southwesterly flow aloft
persist over the western states. Embedded within the
west-southwesterly flow, a series of low-amplitude shortwave troughs
will cross the Rockies, reinforcing a surface lee trough over the
northern and central High Plains.
...Central High Plains...
Southerly surface winds will strengthen across the Plains in
response to the deepening lee trough. At the same time, increasing
boundary-layer moisture and scattered to broken mid/high-level
clouds may limit RH reductions where the breezy winds are expected.
Despite the marginal RH reductions, 20-25 mph sustained southerly
surface winds (with 30-35 mph gusts) could yield locally elevated
fire-weather conditions during the late morning/early afternoon
hours. This will especially be the case over parts of northeast CO,
northwest KS, and southwest NE -- where pockets of 25 percent
minimum RH will be possible prior to the development of showers and
storms. With that said, the aforementioned cloud coverage, widely
scattered showers and storms, and marginal fuels cast uncertainty on
the overall fire-weather threat -- precluding Elevated highlights at
this time.
