.SHORT TERM (Today through Tuesday)...
The mesoscale convective system and cold front boundary that brought
severe storms and heavy rain across the area Sunday afternoon and
evening are about to meet across the northwest Gulf waters. In the
wake of these convective weather systems, isolated light showers
continue to affect the southern counties of South Central Texas early
this morning.

Most HiRes models suggest a lull from precipitation across much of
the area through late this morning. Scattered showers and isolated
thunderstorms are expected to develop across the Hill Country this
afternoon. Some areas may get lucky with no shower or thunderstorm
activity this afternoon or evening while others could get an
isolated shower or several rounds of showers and thunderstorms.

For this evening into Tuesday morning, there is a slight chance for
rain across most of the area with overnight temperatures in the lower
60s across the Hill Country to upper 60s elsewhere.

&&

.LONG TERM (Tuesday Night through Sunday)...
Chances for rain are anticipated to increase late Tuesday night into Wednesday
across the Rio Grande as another short-wave moves across the area.
Showers and isolated thunderstorms are expected to expand in coverage
Wednesday afternoon and evening as instability grows. Area forecast
soundings suggest elevated CAPE values with pwats in 1.7 to 1.8
range, which could result in an episode of strong to marginal severe
thunderstorm development in addition of heavy rain.

The wet pattern continues through the upcoming week as several upper
level disturbances move across the area. Next cold front and
significant weather day looks to be Sunday into Monday of next week.
