Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 755 PM EST Fri Dec 13 2019

UPDATE. Water vapor satellite imagery and 500mb analysis maps show a pretty strong jet streak situated over portions of Southern LA, AL and the Florida Panhandle. This is associated with a negatively tilted shortwave trough axis propagating to the ENE towards the FL peninsula. Across much of the state, conditions remain fairly warm and humid. Dewpoints are running in the upper 60s to low 70s in the wake of what has now become a stationary front. The 0Z sounding also shows a weak veering wind profile, indicative of WAA. Combining this WAA with synoptic-scale PVA, this is the perfect environment for large-scale ascent. Indeed this has already been proven to be true with the earlier line of showers that passed through.

However, conditions have stabilized somewhat for the moment, allowing the atmosphere to recover and regroup for round two. What can also be noted in the 0Z sounding is a pretty decent capping inversion around 820mb. This explains why much of the earlier shower activity likely fell apart (in combination with several other factors like SSTs along the shelf). Despite the inversion, the atmosphere has a fairly deep well-mixed layer just above and just below the inversion . suggesting significant positive buoyancy once once this begins to erode.

While some directional shear is noted in the sounding at the moment, and some weak directional shear will continue to exist, what there will be more of tonight is speed shear. RAP soundings from 6Z onward show little directional shear and only around 30kts of speed shear in the first 3km. This does not make for a particularly high threat for tornadoes, but rather for an environment that could support some damaging wind gusts across portions of West Central and SW Florida.

Suffice all that to say, a line of storms is likely to approach the peninsula in the early hours of Saturday morning, bringing the potential for some damaging wind gusts and an isolated tornado in the overnight hours to the peninsula. This risk diminishes further to the South as convection moves father away from the most favorable environment. Timing sets up for areas North of Tampa Bay to see the greatest threat between 1AM and 5AM and from Tampa Bay Southward from around 4AM to 11AM. The current forecast remains on track, and no major changes have been made.

AVIATION. Conditions remain VFR ahead of an approaching cold front. A line of storms will likely set up overnight and push towards terminals, leading to brief MVFR/IFR conditions, but timing is still not an absolute certainty. For now, will leave VCTS in and later TAFs will add TEMPO/Prevailing groups as necessary to provide a more accurate representation of timing. Conditions could become temporarily MVFR, but after the passage VFR will prevail. Winds out of the SW generally 10kts or less overnight will turn out of the NW by the afternoon.

MARINE. An approaching cold front will bring the potential for showers and thunderstorms overnight into coastal waters with the potential for gusty winds, heavy rain, and possible waterspouts. A potential for sea fog still exists for the Nature Coast, but this will likely be short-lived and patchy in nature. Cautionary statements are in effect for outer waters tonight, but conditions will begin to settle down after the front passes tomorrow.
