PREV DISCUSSION...(ISSUED 359 AM CST Fri Dec 15 2017)
SHORT TERM...Today Through Saturday Night
High pressure is over the area but changes are not far away. Clear
to partly cloudy skies are expected today then the high pressure
moves east of the state Saturday. An upper level low in northern
Mexico Saturday morning will eject to the northeast Saturday and
enter the Plains Sautrday night. As a result moisture will increase
across Arkansas Saturday and temperatures will be a bit warmer. Rain
chances will increase Saturday night. The best rain chances and most
rain will be in the south with lesser amounts north. Will keep the
slight chance of thunderstorms in the central and southern sections.
Around an inch of rain is possible in the south Saturday night.
Highs today will be in the 40s and 50s and Saturday will be in the
mid 50s to around 60 degrees.
LONG TERM...Sunday Through Thursday
The extended period will start off unsettled as a trough rides a
northwest wind flow aloft through the Rockies on Sunday. Ahead of
the trough, a southwest system will eject toward Arkansas, with good
chances of rain continuing.
The 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 Thursday.
With no Arctic air present, at least not yet, temperatures through
Thursday will mostly be above average.
Changes will be on the way Thursday night. A stronger front will
begin ushering in colder air from the Plains. Moisture will be
lacking, with small chances of showers along the front. Below
average temperatures will follow the front beyond the period.
