DISCUSSION. For 02/27/2021 06Z TAF Issuance
AVIATION. With the exception of AEX, CIGS have continued to lower this evening. Expect a mix of IFR/LIFR CIGS overnight. VIS once again has been a little more reluctant to drop, but starting to see some minor reductions from I-10 southward. Guidance suggests BPT/LCH have the best shot at more significant reductions prior to sunrise, though LFT/ARA can't be ruled out. In any case, the very saturated lower levels of the atmosphere result in sluggish improvement after sunrise tomorrow, with IFR/MVFR CIGS likely remaining throughout the day. CIGS begin to lower once more following sunset tomorrow, with guidance once again suggesting some lowering VIS will be possible through the overnight hours, primarily at the southern terminals.

PREV DISCUSSION. /issued 1018 PM CST Fri Feb 26 2021/
DISCUSSION . Wx map shows warm and humid airmass over the region, with temperatures still in the upper 60s to near 70 at this hour, and dewpoints not far behind. Available guidance and persistence shows areas of dense fog likely to expand across the coastal waters overnight, thus leaving the dense fog advisory for all lakes/bays and coastal waters out 60nm. Areas of dense fog may penetrate somewhat inland just beyond the immediate coast, but the latest guidance holds the winds up around 10-15 mph here, as well as around 5-10 mph further inland until diminishing briefly around daybreak. Thus, not extending the dense fog advisory for the coastal zones at this time. Overnight lows not expected to fall lower than the lower to mid 60s, with near 60 across the coast due to the cooler shelf waters.
DML
PREV DISCUSSION . /issued 314 PM CST Fri Feb 26 2021/
DISCUSSION . High pressure is centered near the mid Atlantic coast this afternoon with a frontal boundary stalled from South Texas through central Mississippi and Alabama. The local area remains south of the front with a flow off the gulf. A warm and moist air mass continues to be pushed across the cooler gulf shelf waters between the front and ridge keeping areas of fog over the coastal waters through most of the day. Visibility's are expected to fall again this evening across the coastal waters and perhaps inland as well as the fog advects onshore. Well inland and closer to the front that is stalled across the lakes region and Cen LA a little more mixing may keep the vis higher.
Also tonight and into Saturday the front will begin to lift back north as low pressure develops in the central plains. Another warm day with only a slim chance of a shower well inland is expected.
Sunday the plains low will eject out swinging a cold front to the coast by Sunday night or early Monday. The front will slowly sink into the gulf Monday while an upper level disturbance moves through. A dreary and cooler Monday and perhaps Tuesday can be expected.
Temperatures will be around normal for the date during the middle of the week with a gradual warming trend thereafter.
MARINE . Sea fog will be the main concern through the weekend as a warm and moist air mass moves across the cooler shelf waters. A cold front will move across the coast early Monday decreasing the chances for fog.
