With the subtropical high to the south, SE Texas should remain in a
mostly zonal flow pattern throughout the rest of the work week.
Today a weak frontal boundary sits at our doorstep near the northern
edge of the Brazos Valley. Mostly stalled out, but could meander a
tad further south today before it starts to lift north. With steady
onshore flow and rising moisture, sea fog could develop along the
coast, especially across the nearshore waters and around Galveston
bay. Winds remain elevated, generally in the 10-15 kt range over the
waters, which should broadly limit the extend and intensity of any
sea fog. Still, I wouldn`t completely rule out the potential for
some isolated dense patches Thursday night through Saturday morning,
due to decreasing winds and pooling moisture. SREF still shows
increasing chances for lower visibility (
