fine fuels.

Afternoon highs today will climb into the upper 40s to middle
50s. The dry air mass will bring afternoon relative humidity
values in the 25 to 35% range, though light winds should limit
fire weather concerns. Will need to watch areas in the eastern
Ozarks this afternoon as models have been slightly to high with
dewpoints. this occurred yesterday and have used the NBM 5th
percentile for dewpoints today.

With southerly winds, temperatures tonight will be slightly
warmer in the upper 20s in the Mark Twain National forest areas
and the lowers 30 elsewhere.

into mid to late week with daily highs in the 50s and lows in the
30s. This is around 5 to 10 degrees above normal heading into
mid-December. Dry conditions will persist through the much of the

Upper level shortwave ridging will move across the area Thursday
with an upper low digging into Texas. The track of the upper low
will be tied to where precipitation chance develop for Friday into
thew weekend. As of the latest model runs, the track continued to
