Rain chances will increase this weekMay 7th, 2013 at 9:42 pm by Jim Spencer under Weather
(National Weather Service) An unstable weather pattern will develop over the Southwestern US, leaving a series of weak disturbances aloft to pass across South Central Texas late this week. The first round of thunderstorms expected from this pattern should tap into afternoon heating on Thursday, resulting in a chance of strong to severe thunderstorms that could extend well into Thursday night. Large hail and damaging winds should be the main severe threats. The unstable pattern is expected to continue into Friday and possibly into Saturday as remnant outflow boundaries promote an additional focus for thunderstorm development. Rain chances may be further enhanced if a weak frontal boundary moves south from North Texas.
