Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 839 AM EST Wed Jan 29 2020

UPDATE. A short wave trough and an attendant weak surface low over Louisiana early this morning will slide east across the northern Gulf coast the remainder of today, then across the north central Florida peninsula tonight, then exit east into the Atlantic early on Thursday. Increasing moisture and lift associated with these features will lead to increasing cloudiness across the forecast area the remainder of today with shower chances also increasing by late in the afternoon, with the highest rain chances (Pops 50-60%) expected during tonight as this system moves across the area. Temperatures today will be near seasonal norms with highs climbing into the upper 60s north, and lower to mid 70s central and south. Current forecast is on track with no changes required at this time.

AVIATION. Increasing moisture ahead of a low pressure area approaching from the Gulf will lead to increasing mid and high level clouds aoa 100 at all of the terminals the remainder of today. In addition rain chances will also be on the increase especially during the late afternoon and have handled with VCSH for now. After 00Z tonight prevailing MVFR cigs/vsbys will develop with some lower IFR/LIFR cigs possible after 06Z. East winds in the 6 to 8 knot range will become southwest at 7 to 10 knots after 19Z, then becoming light and variable after 01Z, then becoming northwest after 08Z.

MARINE. An area of low pressure approaching from the west and surface high pressure exiting to the east will support southeast to south winds around 10 knots with seas of 2 feet or less over the Gulf waters the remainder of today with a southwest wind flow component developing near shore during the afternoon. As the low approaches shower chances will increase across the north-central waters during mid to late afternoon with the showers then spreading south and east across the remainder of the waters tonight as the low moves across the region. In the wake of low northwest to north winds in the 10 to 15 knot range can be expected late tonight becoming northeast on Thursday as high pressure briefly builds in through early Friday. Ongoing forecast is in good shape with no changes expected in the mid morning update around 10 AM.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
