Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 232 AM EST Sun Jan 19 2020

. MUCH COOLER TEMPERATURES EXPECTED DURING THE FIRST HALF OF THE WEEK .

DISCUSSION. Areas of showers are developing over the northeastern Gulf of Mexico early this morning in the warm sector ahead of an approaching cold front, currently just reaching the western tip of the Florida Panhandle. This front is on track to move southeast into the forecast area this afternoon and evening, with scattered to numerous showers and a few thunderstorms impacting the area along and ahead of the frontal boundary. Cold air advection behind this front will allow temperatures tonight to drop into the mid to upper 30s across the Nature Coast, although wind speeds are likely a bit too high to lead to widespread frost developing.

A couple of mid level shortwave troughs will dig into the southeastern US Monday and Tuesday, resulting in even stronger pushes of cold air advection across the Florida Peninsula, and perhaps the strongest cold snap of the year so far. Cool and breezy days are expected Monday through Wednesday, with afternoon highs forecast to top out only in the 50s and 60s. Tuesday morning low temperatures will drop into the low 30s over much of the Nature Coast counties, with parts of Levy County expected to touch freezing for a couple of hours. Additionally, wind chills will drop to below 35 as far south as northern Hillsborough and Polk counties, although wind speeds may not be quite high enough to meet advisory criteria. Wednesday morning is forecast to be the coldest morning of the week, with freezing temperatures forecast as far south as Brooksville, and lows in the mid to upper 30s expected away from the coast throughout west central and southwest Florida. Wind speeds will also be high enough to drop wind chills to be below freezing across virtually the entire forecast area early Wednesday morning.

Surface high pressure will build in from the north during the second half of the week, allowing temperatures to quickly rebound back to above normal by Friday. A weaker cold front will approach from the west Friday and Friday night, with another round of showers expected, and slightly cooler temperature expected for the weekend.

AVIATION. Mostly VFR conditions are expected to hold through around 15z, then isolated to scattered showers, along with MVFR or possibly IFR ceilings will move southeast into the Tampa Bay area terminals, generally around KTPA, KPIE, KLAL, and KSRQ. These ceilings will begin to lift out around 00-03z. Farther south, the showers are expected to mostly dissipate before reaching KPGD, KFMY, and KRSW, but MVFR or IFR ceilings are expected to move in after sunset, and could hold overnight.

MARINE. A cold front will move southeast through the waters today, bringing scattered showers and a few thunderstorms. Winds and seas will increase behind the front, with cautionary level winds expected over the Gulf waters from Tarpon Springs to Suwannee River by late this afternoon, and advisory level winds and seas expected to develop over the Gulf waters north of Englewood tonight and continue into early Monday morning. Cautionary level winds will hold through Tuesday, when winds are expected to increase again to advisory levels in response to a weak surface wave developing east of Florida. Winds will gradually subside again Wednesday and Thursday as high pressure builds in from the north.

FIRE WEATHER. Slightly drier air will fill into the region Monday behind a cold front, with relative humidity percentages dropping into the mid 30s for a few hours Monday and Tuesday afternoons. However, wind speeds are not expected to be high enough to trigger Red Flag conditions.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
