Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 301 AM EST Tue Jan 21 2020

. DRY AND VERY COLD AIR WILL CONTINUE TO SWEEP INTO THE AREA .

SHORT TERM (Today - Wednesday). Aloft: A trough over the southern and central Appalachians shifts offshore tonight and over the Atlantic Wed as a ridge from the Rio Grande Valley to the Canadian prairies slides east . stretching from the Gulf of Mexico to the Saint Lawrence Valley by Wed night. Surface: Strong and sprawling high pressure along the NE/IA border works eastward to the Atlantic coast Wed.

The upper level trough and surface high pressure will maintain dry and cold northern flow into Wed. Freezing temperatures are expected across parts of the Nature Coast before dawn . with durations supporting a freeze warning in Levy County. Today will be on the chilly side with afternoon highs about 10 to 15 degrees below normal. This cold air continues tonight into Wed morning with some even lower temperatures . a freeze warning is in effect for the Nature Coast with a freeze watch from Pasco to Sarasota-Desoto away from the coast. In addition winds remain high enough overnight for a wind chill advisory for the entire area. Finally the northerly flow will take on a slight onshore component today and result in a high risk of rip currents. The highs for Wed will continue on the cool side but warm by 3 to 5 degrees.

LONG TERM (Wednesday night - Monday). High pressure along the eastern seaboard at the start of the period will move east into the Atlantic during Thursday and Thursday night as the next storm system over the Mississippi valley moves east toward the mid Atlantic coast. As the high shifts east winds will veer to the east and southeast with moderating temperatures and a slow increase in moisture expected. As the aforementioned storm system moves eastward a trailing cold front will move east across the Gulf through Friday, and then south through the forecast area during Friday night and early Saturday bringing with it some low rain chances along and ahead of it. In the wake of the front cooler and drier conditions will return Saturday night through Monday as high pressure builds in over the area. Temperatures will moderate back to near normal Thursday through Saturday, before falling back to below normal during Sunday and Monday in the wake of the front.

AVIATION. 21/06Z. VFR. N winds back slightly and become gusty AFT 14-17Z.

MARINE. High pressure moving across the central then eastern U.S. along with low pressure in the Atlantic will result in robust to strong winds on the Gulf waters. A Small Craft Advisory will be in effect through Wed. Bay and harbor waters will see slightly lower speeds but still in the Exercise Caution range. As the high tracks east winds begin to diminish and veer midweek.

FIRE WEATHER. Cold and dry air continues for the next couple of days . with the Nature Coast seeing RH below 35 percent for perhaps 2 to 4 hours. But low ERC values and light winds will preclude any Red Flag conditions. Moisture slowly recovers during the rest of the week.

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.
