Short term (today through thursday)...
the middle to upper level trough will move off to the east today as a
ridge builds across Texas from Mexico. At the surface...high
pressure will remain in place over the Gulf. This will be a dry
pattern for south central Texas. Surface winds will remain from
the south to southeast. This will bring morning cloudiness to the
eastern two-thirds of the area. These clouds will burn off this
afternoon for a mostly sunny afternoon with high temperatures a
few degrees above normal. The next 24 hours will be essentially a
repeat with the upper level ridge becoming more strongly
established.
Long term (thursday night through tuesday)...
little change in the pattern through the end of the week. The
upper ridge will dominate and surface high pressure will remain
over the Gulf. This will mean a dry and warm forecast. Some minor
changes by the end of the weekend. Some minor height falls in the
middle to upper levels will allow a moisture surge from the Gulf
to enter the southeastern part of our County Warning Area. This will bring
afternoon and evening convection to the area starting Sunday. Only
slight chances for precipitation each day through the end of the period.
