/Issued 902am CST Tuesday Nov 30 2021/

Latest satellite imagery shows the fog has cleared over the bays and near shore waters. Will cancel the advisory early for this area.

Short Term - Today Through Wednesday
A weak upper level disturbance is expected to develop/move across the Southern Plains today, while another stronger upper system moves across the Northern Plains late this afternoon/evening, then over the Mississippi Valley/Midwest tonight, before merging with the weaker system to generate a trough that moves across the SERN CONUS Wednesday, while an upper cutoff low meanders over the Baja CA region. Lift associated with the SRN Plains system is expected to remain north of the CWA. PWAT (Precipitable Water) values are expected to slowly increase to near normal by tonight. No significant precipitation is expected over the CWA during the period. Areas of dense fog over the Coastal Plains early this morning will dissipate during the mid morning. Patchy fog may occur again 09-12z Wednesday inland.
Long Term - Wednesday Night through Monday
A mid-level cutoff low that develops near the Baja Peninsula will oscillate between SOCAL and the Baja Peninsula over the course of the work week. A series of shortwave disturbances will move around the southern periphery of the low and eastward into South Texas from late in the week through the weekend. Moisture will increase as the week progresses, with PWAT (Precipitable Water) values reaching to around 1.5" by Thursday. PWAT (Precipitable Water) values will remain around 1.5" through the weekend. The combination of mid-level shortwave disturbances, PWATs (Precipitable Waters) above the 75th percentile, and isentropic lift will lead to a chance of showers and thunderstorms along the Coastal Bend and Coastal Waters through the weekend.
Latest model guidance has pulled back with regards to the cold front on Saturday, with the Canadian being the only guidance suggesting a front pushing through South Texas; however, models do point to a front approaching the area Monday. PWAT (Precipitable Water) values for Monday continue to remain around 1.5" for the Coastal Bend ahead of the front. Have kept slight Probability of Precipitation in for the Coastal Bend into the Coastal Waters as the combination of moisture and H5 energy could lead to the development of showers and thunderstorms; however, with it being late in the period, guidance could change with regard to timing and location of any precipitation.
Max temperatures through the long-term period will remain in the 70s and 80s with nighttime lows generally in the 50s to 60s.
Areas of dense fog early this morning over the bays and portions of the nearshore coastal waters. Otherwise, weak onshore flow expected today. Generally weak onshore flow and increasing moisture expected Wednesday through Saturday. An upper level disturbance will continue.ibute to isolated showers and thunderstorms Friday and Saturday.
