.PREV DISCUSSION...(ISSUED 251 PM CST Wed Nov 22 2017)
SHORT TERM...Tonight Through Friday

Cool, dry weather is expected through the short term portion of the
forecast as elongated surface high pressure settles in over the area
from southwest to northeast. The flow aloft is out of the north
helping to usher in cooler air.

A few high clouds may be seen across mainly northern and western
areas on Thanksgiving Day as a weak ripple in the flow carries a
little elevated moisture across the state.

By Thursday afternoon into Friday, high pressure will move southeast
of the area bringing a return of southwesterly winds to the state
and a bit of a warmup. Expect highs to top out in the 60s to near 70
degrees with winds a bit elevated as the surface pressure gradient
is compressed a bit, especially across northern areas.

LONG TERM...Friday Night Through Wednesday

Northwest flow aloft will be over Arknasas to begin the long term
period with high pressure over the southwest and an upper trough
over the northeast. The upper ridge will spread to the east through
the weekend as another upper trough enters the Pacific Northwest.
This trough moves into the Plains Monday and Tuesday and to the east
coast Wednesday.

Dry conditions will continue through the long term period. High
pressure will be over the state for much of the period. However, a
cold front will move through the state Friday night and
Saturday...and again on Tuesday night. Moisture will be lacking with
both systems. No rainfall is expected. Mainly above normal
temperatures are expected through the long term period.
