.DISCUSSION...
Near critical fire wx conditions are expected across much of the
area today. Temperatures this afternoon will climb into the upper
90s to low 100s with minimum RHs at or below 20% across much of
western SD into northeastern WY. Northeastern WY into southwestern
SD could see critically low RH values (15% or lower) with breezy
southerly winds developing through the afternoon hours. Lowest RH
values and strongest winds won`t overlap considerably in time and
space, so will hold off on issuing any fire weather headlines.
However, locally critical fire wx conditions are possible this
afternoon, especially across northeastern WY into southwestern SD.
Elevated to near critical fire wx conditions are possible again
on Thursday as a cold front pushes through the region. Winds will
shift to the northwest through the day Thursday with gusts of
25-30 mph. Temperatures Thursday will still be hot, in the 80s to
near 100, with minimum RH values in the 25-45% range.
