PREV DISCUSSION...(ISSUED 402 AM CST Thu Dec 14 2017)

SHORT TERM...Today Through Friday Night
High pressure will remain over the area through the short term
period with no precipitation expected. Satellite images this
morning show a band of high clouds moving into north Arkansas and
far southern Arkansas. Models indicate an increase in moisture
this afternoon and tonight and expect this to be in the form of
mainly high clouds. Wildfire danger remains high but humidity
values will be higher than yesterday...40 to 50 percent. High
temperatures today will be from the lower 40s to mid 50s...and mid
40s to mid 50s on Friday.

LONG TERM...Saturday Through Wednesday
The extended period will start off unsettled as a trough rides a
northwest wind flow aloft through the Rockies and Plains
Saturday/Sunday. As the trough nears, a southwest system will eject
toward Arkansas ahead of the trough, with moisture increasing. This
will not be tropical by any means, with dewpoints getting into the
40s to lower 50s. Clouds will thicken, and there are good chances of
showers in the forecast.

Rainfall through early Monday could be in the half inch to inch and
a half range from Little Rock to the south/east. Quarter to
half inch amounts are expected farther north/west.

The aforementioned trough will lag a bit, with chances of rain
continuing across the southeast counties Monday/Monday night.
A weak cold front will pass through the region by Tuesday, with
high pressure and dry weather to follow through Wednesday.

With no Arctic air present, at least not yet, temperatures through
the period will mostly be above average.
