Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 300 AM EST Sun Dec 15 2019

DISCUSSION. Mid level ridging builds in across much of the Gulf region through tonight then eases east Mon as a trough slides into the Mississippi Valley from the west by Mon night. At the surface - a cold front south of the Florida Keys dissipates today as high pressure centered along the GA/FL moves east across the Atlantic tonight and Mon while stretching back to the central Gulf of Mexico.

A dry and stable airmass prevails for the next couple of days with sunny skies. However light winds and residual low level moisture are allowing some patchy fog to form this morning that will lift and mix out by 8 or 9 am. Cool Temperatures this morning gradually warm to above by Mon. While winds and waves on the Gulf are diminishing they will still support a high risk of rip currents through midday.

For Tue-Sat: The mid level trough noted above slides across the eastern U.S. and swings a cold front across FL Tue and early Wed with showers and cloudy skies. Deep layer ridging builds into the Gulf region late Wed-Thu and shifts east to FL Fri with a dry and stable air mass. A deep low with a cold front stretching south moves into the lower Mississippi Valley and central Gulf of Mexico Fri then tracks to the southeast U.S. coast and FL Sat. These features provide increasing moisture across the area with a chance of showers and thunderstorms for Sat. Temperatures initially run above normal then drop significantly after the front passes midweek. They slowly warm through Sat. Model discrepancy introduces some uncertainty in the end of the forecast . the GFS is a tad faster and more robust than the ECMWF.

AVIATION. 15/06Z SKC prevails but with some limited BR. especially LAL and PGD which will see some MVFR to IFR BR and ST TIL 13Z. FEW CU/SC drift in toward the end of the period. Light and VRBL winds become E and SE during the day AOB 9kt.

MARINE. Light to gentle easterly winds gradually veer as high pressure moves away and a front with some showers approaches Tue. Winds become northerly at 20 to 25 knots as the front crosses the waters and high pressure settles.

FIRE WEATHER. Slightly drier air works in today but then gradually moistens through early in the week with minimum RH values staying above critical levels. The next cold front ushers in drier air but also some cooler temperatures . keeping the RH out of critical ranges.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
