.PREV DISCUSSION... /issued 343 PM CST Sat Dec 3 2016/

SHORT TERM...
(Tonight and Sunday)
An unsettled pattern will continue during the next 24 hours as a
well developed upper level low remains over northwest Mexico. Also,
our area will see weak mid to upper level ascent and some isentropic
upglide/overrunning over the cool airmass in place. The Hi Res
models indicated another area of showers moving northeast across
West Central Texas late this evening into the early morning hours,
and then more showers and a few lightning strikes possible across
the southern half of the area by late Sunday morning and afternoon.
The highest rainfall amounts(0.25 to 0.75 inches) will be along the
I-10 corridor. Also, expect patchy fog late tonight and Sunday
morning due to saturation in the boundary layer and light winds.
Temperatures will remain cold, with lows in the lower 40s and highs
Sunday in the upper 40s to lower 50s.

LONG TERM...
(Sunday Night through Saturday)

Upper level low moves out of Mexico and across the Hill Country
late Sunday Night into Monday, producing another widespread wave
of showers and a few thunderstorms. Best chances across the
southeast counties along and south of a San Angelo to Abilene
line. Upper low shifts east and takes the rain with it, leaving a
dry forecast in store.

A weak frontal boundary is forecast to drop through the area on
Tuesday behind the upper low, but a return of sunshine will
largely offset any cooling. Highs in the mid 50s to lower 60s
expected. Stronger arctic front drives through the area late
Wednesday, most likely after peak heating. This will need to be
watched however, if it comes through faster than expected, highs
for Wednesday will need to be dropped. Temperatures for the rest
of the week to remain cold, with highs on Thursday in the upper 30s
and lower 40s. Lows will be dropping well below freezing, into the
low to mid 20s in many locations.
