.PREV DISCUSSION... /ISSUED /

SHORT TERM...Today through Sunday night.

Latest moisture channel imagery shows the upper pattern quite
clearly this morning. Pattern currently dominated by a trough over
the pacific northwest, ridging in the central plains and subsequent
downstream troughing over the Great Lakes.

Current observations showing patchy fog across the region but not to
the point where any headlines are needed and it should burn off by
mid to late morning.

Area currently under northwest flow at this time with a weak upper
wave expected to drop SE this afternoon and tonight. Wave may
trigger a brief shower to the north and west of the area but will
keep our CWA dry. Pattern will amplify through the weekend with
upper ridge cresting over the area late this weekend. Another weak
wave will approach western Arkansas very late in the weekend for
minimal precipitation chances late in the period. Temperatures will
average a few degrees below normal.

LONG TERM...Monday through Friday

An upper ridge will continue over Arkansas to begin the long term
period. Upper lows will be over the east coast and the Pacific
Northwest Monday. This pattern will continue until Wednesday when
the ridge moves to the east coast and the western low dives toward
the four corners region. Southwest flow will continue over Arkansas
Thursday and Friday.

Surface high pressure will be over Arkansas through much of the
period. However...several short waves will move through the area
through the week. Moisture will begin to return to the state Monday
and rain chances will increase. Models indicate a chance of showers
and thunderstorms each day of the extended period. Below normal
temperatures are expected Monday...but will be back to near normal
Tuesday through Friday.
