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.
