GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 316 Am Est Sun Jan 26 2020
Synopsis..High pressure over the northern gulf slides off to the east, resulting in northerly winds to gradually shift to the northeast on Sunday. A weak sea breeze will allow for an onshore component during the afternoon. An approaching weak surface low on Monday will shift winds to the south and bring some isolated showers over the waters. Otherwise, no hazardous marine conditions are expected for the next 5 days.

Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 641 AM EST Sun Jan 26 2020

AVIATION. VFR conditions expected through the period. Winds will remain light and variable through much of the period with northeast wind possible in the afternoon and evening.

Prev Discussion. /issued 314 AM EST Sun Jan 26 2020/

DISCUSSION . Cool, fairly calm, and dry are the big words to kick off Sunday. Surface high pressure remains in control as a subtle upper-level ridge axis continues its eastward propagation. This will lead to the continuation of fair weather conditions leading into Monday.

The upper-level pattern is fairly zonal across much of the Southeast, and really won't change all that much over the next few days. However, a couple shortwave perturbations will propagate eastward, and this will aide in keeping our weather pattern at least mildly interesting for the first half of the work week. These shortwave troughs will provide a concentrated zone of ascent, aiding in the development of showers and possibly thunderstorms. The big question yet to be completely resolved is will these systems hold together long enough to provide us rain.

Late Monday has the greatest chance for that to take place, but it is still fairly week. Convection is quick to fire off over the warm and moist central Gulf, but the rapid weakening of the shortwave trough, and the fairly hostile environment that the convection will be moving into, really only yield the opportunity for some scattered showers and maybe an isolated thunderstorm favoring SW Florida. A similar story is playing out for Wednesday too, but favoring the Nature Coast instead.

Late week is when things become much more interesting. Details are still fuzzy this far out, and model guidance differs significantly, particularly in timing. However, conditions are favorable ahead of a much deeper trough axis for a low pressure system to develop that will bring unsettled weather for the weekend. In the wake of this front, cooler and breezier conditions can be expected with high pressure again in control.


MARINE . Pleasant boating conditions continue through Sunday. Several weather systems throughout the week could lead to rounds of showers beginning on Monday and continuing off and on through the rest of the work week, but conditions are expected to remain otherwise benign for boating with northerly winds turning southerly as the next system approaches and then northerly again once it passes.

FIRE WEATHER . With a dry high pressure system in control, dewpoints will likely drop across much of the region below 35 percent for a couple hours this afternoon. ERCs also creep into the upper 20s to around 30 for some counties as well. However, winds are expected to remain light. As such, no red flag conditions are expected at this time. Humidity values will improve towards the evening and will begin to rebound further heading into Monday as a weak low pressure disturbance moves toward the Florida coastline, potentially bringing with it a few showers. No further fire weather concerns exist through the remainder of the forecast period.
