.PREV DISCUSSION... /ISSUED 333 AM CST Tue Nov 20 2018/ 

SHORT TERM (Today through Wednesday Night)...
An upper level impulse overhead will be east of our area by midday.
Lower to mid level ridge builds in to continue the ongoing clearing 
trend with mostly sunny skies resulting in warmer temperatures for 
all areas today. This will be short-lived as a compact upper level 
shortwave currently off the northern Baja California coast moves 
across Central Texas Wednesday and Wednesday night. Clouds return 
tonight due to moisture advection. Upward forcing leads to slight 
chances of showers Wednesday morning with stronger forcing from Noon
to Midnight. However, significant moisture return is not expected as
PWs peak just above an inch and have maintained the low chances for 
showers. Showers end by late evening or early overnight as the 
trough moves east of our area. Rainfall amounts of less than 1/4 inch
are expected. Clouds and rain keep temperatures cooler again on 
Wednesday. 

LONG TERM (Thursday through Monday)...
Thanksgiving looks mostly cloudy with below normal temperatures, 
though warmer than Wednesday due to a few more peaks of sunshine. On
Friday, an upper level trough currently off the west coast near 140W
moves rapidly across the Southern Plains along with a Pacific front.
A brief period of upward forcing results in low chances of showers
during the morning hours. Weak elevated instability may generate an
isolated thunderstorm. In the wake of the Pacific frontal passage,
southwest to west winds result in warmer, above normal, temperatures
for Friday and Saturday. An upper level trough moving across the 
Central and Northern Plains forces a Canadian cold front across our
area Saturday night into early Sunday morning. Lack of moisture 
convergence along the front keeps POPs out of the forecast. A strong 
surface pressure gradient along with mixing of stronger winds aloft 
should make for a breezy day on Sunday. Temperatures drop back to 
below normal on Sunday, then more so on Monday.
