.PREV DISCUSSION... /issued 254 PM CST Sat Jan 20 2018/ 

SHORT TERM...
(Tonight and Sunday)

..Critical Fire Weather Conditions and Windy Sunday...

A strong upper level trough/low will pivot northeast from the 
southern Rockies Sunday into the central Plains by Monday morning. 
This upper level system will drive a dryline/cold front east 
across West Central Texas Sunday afternoon. In the wake of its 
passage, expect strong west winds of 25 to 35 mph with gusts to 45
mph possible due to good downward vertical mixing, north of an 
Ozona to Brownwood line. Going with a Wind Advisory across from 11
AM to 7 PM across this area of West Central Texas. it will be 
breezy elsewhere, with gusts to 35 mph possible. Also, critical 
fire weather conditions are expected north of an Ozona to 
Brownwood line and elevated fire weather conditions elsewhere 
Sunday afternoon. See fire weather discussion below.

LONG TERM...
(Sunday Night through Saturday)

Looks like mainly quiet weather and mild temperatures through this 
week. Aloft, quasi-zonal flow will keep West Central Texas mainly 
dry. A few showers are possible Friday night across the southeast. 
Highs will be mainly 60 to 65, with lows in the upper 20s and 30s.

FIRE WEATHER...

The headline for fire weather concerns highlights critical fire 
weather conditions developing Sunday, as a cold front moves into 
West Central Texas, from the west. We have canceled the Fire Weather 
Watch and issued a Red Flag Warning. The Red Flag Warning will begin 
at 11 AM Sunday morning and continue until 7 PM Sunday evening. It's 
during that time frame when winds will be highest and relative 
humidity will be lowest. Winds at 20 feet above ground level, will 
be from the west, at 20 to 25 mph, with possible gusts in the 35 to 
40 mph range. For those counties in the warning, critical fire 
weather conditions are likely. For those counties not in the 
warning, fire weather concerns will be near critical, as 20 foot 
winds, from the west, should remain below 20 mph.
