Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 1236 AM EST Wed Feb 19 2020

AVIATION. Some MVFR/IFR ceilings and visibilities as well as a few showers will be possible at area terminals through mid morning today. VFR conditions should then hold through the rest of the day and early evening.

Prev Discussion. /issued 842 PM EST Tue Feb 18 2020/

UPDATE . We had another warm and rather humid day with a few record high temperatures tied. The west coast sea breeze moved well inland into the interior counties this evening, but will weaken and washout soon. For the rest of tonight we'll see a pocket of deeper moisture move northwest into the region with an increase in southeast winds just off the surface associated with it. This should lead to a similar to scenario to what we saw last Wednesday morning when we woke up to a few showers moving northwest across central Florida. Otherwise, expect more low clouds and some fog to develop with the best chances for restricted visibilities across the northern Nature Coast and Southwest Florida. Overall the current forecast looks on track at this time.

MARINE . Some more sea fog is likely to redevelop overnight into Wednesday afternoon across the northern waters. Otherwise, pleasant boating conditions are expected through Thursday before the next cold front approaches late in the work week bringing increasing winds and seas. Robust northeast winds are expected to produce exercise caution to advisory conditions Friday and Saturday, then winds and seas will subside during Sunday.

Prev Discussion . /issued 254 PM EST Tue Feb 18 2020/

DISCUSSION . Near record high temperatures are expected today as surface high pressure to our east with the low level ridge axis extending across Central FL provides our area with southerly flow. The 12Z sounding from TBW showed a shallow veering wind profile in the low levels which infers warm air advection continues. In addition to the warm temperatures, the spatial and temporal extent of sea fog will be the main concern into the overnight hours. The atmosphere continues to be favorable for fog/low stratus and this is expected to be an issue again tomorrow morning. This will predominately affect south interior counties(i.e. Highlands, DeSoto) and portions of the Nature Coast. Warm and benign weather is expected tomorrow with highs once again in the mid 80s.

Wednesday night into Thursday morning, a cold front will push south across the region. A shortwave moving across the Central part of the CONUS will trigger surface cyclogenesis off the Carolina coast while strong surface high pressure builds across the Middle Mississippi Valley. In between these two features, Florida will receive a fresh north/northeast wind as a strong SE to NE pressure gradient sets up across the Peninsula. The tight gradient will produce strong winds across the waters and as a result, hazardous boating conditions can be expected Friday into the day on Saturday. This wind will also advect much drier and cooler air across the region. While nothing very cold is expected, we will see much more pleasant temperatures Friday into the weekend with temperatures running 10-15 degrees cooler and lower dewpoints. Parts of the Nature Coast may even dip into the 30s Saturday morning. A rain chance will exist, mostly late Thursday into Friday as the low pulls away from us and rain wraps around its western flank.

The pleasant weather will quickly fade as southeast flow returns on Monday due to high pressure establishing itself to our northeast. Highs will be in the upper 70s to low 80s. Meanwhile, a shortwave with an associated closed surface low will quickly traverse the Central CONUS. This system will bring our next chance for a cold front and will likely move through the area on Tuesday, bringing an increase in rain chances and cooler weather by the middle of next week.

FIRE WEATHER . Poor overnight dispersions are expected for the next couple of nights with the formation of some fog and low clouds through early morning hours. Warm afternoon temperatures with strong mixing through mid week. RHs will remain well above critical values as humid airmass remains in place. A cold front will move through later in the week which will shift winds out of the north and bring in cooler/drier air.
