Day 1 Fire Weather Outlook

1149 AM CDT Mon Oct 27 2025



Valid 271700Z - 281200Z



...Central High Plains...

Strong mid-level west winds across the central Rockies and a

strengthening lee trough over the central High Plains is still

expected to support enhanced downslope winds of 15-25 mph and drying

along the Colorado Front Range through the afternoon. RH reductions

during peak afternoon heating and boundary layer mixing of 15-20%

will be common and as low as 10% in some locations. The breezy and

dry conditions along with drier fuels/cured grasses will promote an

elevated fire weather threat. Some modifications were made to

previous Elevated highlights based on latest forecast guidance and

observations.

.PREV DISCUSSION... /ISSUED 1241 AM CDT Mon Oct 27 2025/



...Synopsis...

A strong mid-level jet will be present across the central Rockies

today. A lee trough extending from a surface low in the northern

Plains will drive strong downslope winds in parts of the High

Plains. Behind the upper trough, a surface high will build into the

Northwest and Great Basin, especially toward Tuesday morning.



...Central High Plains...

Surface winds of 15-25 mph can be expected behind the lee trough.

Higher wind gusts will also be possible. RH with northward extent is

somewhat uncertain, but areas within the Front Range have potential

to have 15-20% during the afternoon. Given the relative lack of

precipitation in the vicinity of northeast Colorado, fuels will

support elevated fire weather concerns.



...Southern California...

Offshore winds will likely begin sometime this morning and steadily

intensify through the day into Tuesday morning. RH reductions during

the period do not appear overly large. Furthermore, area fuels are

not sufficiently dry to support significant fire weather concerns.
