.PREV DISCUSSION... /ISSUED 844 PM CST Thu Dec 14 2017/

DISCUSSION...
A weak cold front has moved off the coast and high pressure over
eastern CO was slowing pushing south. A large swath of clouds
extended from western Mexico across TX will persist tonight and
much of Friday with maybe some partial clearing from the north
late Friday. Made some minor tweaks to the grids but the current
forecast is in good shape so no significant changes planned.

A vigorous short wave trough heads this way on Saturday and this
feature coupled with high PW air and favorable jet dynamics should
yield a pretty good chance of storms. Depending on how far inland
the surface low tracks will determine if any strong storms can
develop. Strong storms or not, some areas will receive some
healthy December rainfall. 43
