Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

Synopsis.. A cold front will move into the northern waters on Wednesday, and then into the central waters Wednesday night where it will stall out through Thursday. The potential exists tonight for sea fog, which may eventually extend south to the mouth of tampa bay. SEa fog may persist through Wednesday morning over the cooler northern shelf waters. As the front moves into the area increasing northeast winds and seas are expected, with a period of cautionary or near advisory level conditions possible Wednesday afternoon into Thursday morning, especially across the central and northern waters.

Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 1239 AM EST Wed Dec 11 2019
AVIATION. Patchy fog and low stratus will continue to develop through just after sunrise this morning, with extended periods of MVFR-LIFR conditions expected through at least 14z. The MVFR ceilings will then likely linger through the rest of the morning. Even as ceilings lift out, isolated showers cannot be completely ruled out at any time after sunrise, and could cause brief periods of reduced flight categories. Another round of MVFR or lower ceilings will develop after around 00-02z this evening.
Prev Discussion. /issued 726 PM EST Tue Dec 10 2019/
UPDATE . The forecast for tonight and tomorrow can be summed up in one word: messy. By far, the biggest concern is for fog. Ahead of an advancing cold front, the air is very close to saturation. Areas of fog are expected to develop across most, if not all, of the region in the overnight hours. The potential does exist for dense fog, but certainty is not high enough yet to mention. This will be assessed overnight and through the early hours of tomorrow.
In addition to the fog, low clouds and rain showers will be intermingled. Ascent along and ahead of the cold front is not particularly good, but good enough to support at least some shallow shower activity. In fact, a few showers are currently underway across portions of the interior. These showers are weak and will likely be brief. Additional showers that form will likely exhibit the same characteristics.
Low clouds will likely hang around for much of the day, and the front will also help to usher in additional unsettled weather lasting into the weekend. Minor tweaks to POPs have been made for the next couple hours, and the forecast has been updated to reflect a higher likelihood for more fog. Otherwise, the forecast remains on track and no additional changes have been made.
MARINE . Showers and the potential for sea fog exist tonight across much of the coastal waters as a front approaches. Behind the front, a north wind will begin to increase, bringing winds up to cautionary/advisory criteria by tomorrow night.
