.PREV DISCUSSION... /ISSUED 320 AM CDT Wed Mar 28 2018/

SHORT TERM (Today through Thursday)...
The heavy rain threat continues across South Central Texas early
this morning while the threat for severe storms has diminished. A
Flash Flood Watch is in effect through this evening. The Severe
Thunderstorm Watch earlier issued from the Storm Prediction Center
has been allowed to expire as of 3 AM this morning.

An outflow boundary that moved through the area and into the coastal
plains Tuesday afternoon and evening, came back up into the I-35
corridor late Tuesday night and continues to do so early this
Wednesday morning. As this boundary continues to push northward, it
is expected to interact with a cold front pushing across Edwards
Plateau/western Hill Country. In addition, several upper level short
waves coming across northeast Mexico into the southwest part of
South Central Texas will help supporting more showers and
thunderstorms throughout the day.

As the cold front slowly pushes to the south this morning, several
rounds of heavy rain are possible in addition of strong to severe
thunderstorm development mainly east of I-35 corridor. Main severe
weather threats for today will be large hail and damaging winds in
addition to localized flash flooding due to heavy rain episodes.

Showers and thunderstorms continue this evening into Thursday
morning as the cold front finally pushes off into the coastal
waters.

New rainfall totals from today into Thursday morning range from one
to three quarter of an inch along the I-35 corridor and up to 1.5
inches across the coastal plains. One quarter inch and lesser amounts
are expected across the southern Edwards Plateau and Rio Grande.

By late Thursday morning, all precipitation should be far out from
the area with mostly sunny skies spreading from west to east with
highs in the 80s.

LONG TERM (Thursday Night through Tuesday)...
An upper level northwest to zonal flow will keep South Central Texas
dry for the latter part of the week into the weekend. There is a
slight chance for showers on Monday as a cold front approaches from
the north. The GFS solution keeps the area relative dry with some
drizzle in the morning while the ECM has a better signal for light
showers. At this time, we will go with slight chances for showers and
adjust weather grids accordindly with new model runs in future
forecast packages.
