.PREV DISCUSSION... /ISSUED 305 PM CDT Thu Mar 26 2020/

SHORT TERM (Tonight through Friday Night)...
An upper level ridge is over the Gulf and a trough lies over the
west coast. The flow over Texas is from the southwest. In the low
levels the winds are from the southeast keeping warm, moist air in
place. Temperatures are in the 80s and dewpoints in the middle to
upper 60s across South Central Texas. This pattern will shift slowly
to the east with southeasterly low level flow continuing tonight. It
will be another warm night with low cloudiness developing across the
eastern half of the CWA late tonight. Friday the upper trough will
move across southwestern states and bring a Pacific cold front
toward West Texas. The low level winds will remain from the
southeast and Friday will be another rain free and very warm day.
The cold front will move into our northwest counties late Friday
night bringing low chances for showers before midnight. As the front
continues to push to the east we will have better chances for
showers and isolated thunderstorms after midnight Friday/Saturday.
The best rain chances will be across the northern half of our CWA.
PW is forecast to be moderate and rainfall totals will be modest with
the highest totals around a tenth of an inch.

LONG TERM (Saturday through Thursday)...
The cold front will be moving across the Hill Country mid-late
Saturday morning and over the coastal plains by mid afternoon.
Rainfall amounts could range from the one tenth to one quarter inch
over the Hill Country and areas along and east of I-35. Behind the
cold front, strong northwest winds will take over the area with winds
of 15 to 25 mph and gusts up to 35 mph. This brings a fire weather
concern for areas along the Rio Grande for the Saturday afternoon
period.

Dry weather is in store for Saturday afternoon for most areas
as the cold front pushes away and continues into Sunday. Cooler
temperatures are expected for Sunday morning with lows in upper 40s
across the Hill Country to 50s elsewhere.

Sunday`s high temps are forecast to be around the upper 70s and lower
80s under mostly cloudy skies. Moisture will continue to increase
Sunday evening into Monday ahead of our next cold front, which
arrives on Monday and exits the area by Tuesday morning. This front
brings better chances for widespread rains than the one for Saturday.

After the passage of the front on Tuesday morning, expect dry weather
conditions and temperatures closer to normal values.
