DISCUSSION. . Frigid Wind Chills Expected Tonight . . Very Hazardous Boating and Beach Conditions Developing Today .

Today . A high pressure centered over central U.S. this morning will shift generally to the east. Then this evening, a surface to upper levels low pressure will develop off the coast of GA/FL and move east. Locally, this will keep a NNW wind flow over land, increasing today as the pressure gradient tightens. After a cold start this morning with temperatures dropping below 50 degrees, highs will present a gradient north to south. Mid 50s from Orange/northern Brevard northward while upper 50s to lower 60s from the Cape and Osceola southward.

Along the coast, as winds and seas increase today, a few headlines to note. A Beach Hazards Statement was issued to bring attention to the strong long current that will develop as winds pick up from the NNW. Rip currents will also be tricky near inlets and jetties, especially near low tide this afternoon. And for those along the barrier islands and coastal areas, a Lake Wind Advisory was issued as winds will increase to 15 to 20 mph and gusts up to 30 mph late this morning and afternoon.

Tonight . Winds from the NNW will bring the coldest air so far this season to east central FL. A Wind Chill Advisory is in effect after midnight through early Wed morning as we expect for cold temperatures to combine with winds of 10 mph or higher to produce wind chills of 35 degrees or less. Plan ahead to wear layers if going outside tonight and Wed morning. A Freeze Watch also remains in effect for Lake and inland Volusia counties as sub- freezing temperatures as low as 30 are possible late tonight.

Wednesday-Thursday . Upper low pushes offshore the GA coast early Wednesday, forming a stacked sfc low just offshore the east central FL coastline. Driven by high pressure sinking through the Appalachians, the pressure gradient will remain tight, with brisk northwest winds becoming northerly by midday Wed, veering northeasterly by Thu. With sfc low positioned just offshore, highest rain chances will remain over the Atlantic waters at 50-60%, tapering significantly toward the coastline. Coastal locations from southern Volusia to the Treasure Coast can expect a 30% chance of showers Wednesday, with interior sites remaining dry with PWATs of 0.3-0.5" west of the St Johns basin.

By Thu, the offshore low quickly deepens and pulls to the open Atlantic waters, as the high shifts to the Mid-Atlantic states. As a result, the pressure gradient across the region will weaken, with northeasterly winds less than 10 mph over land. Rain chances Thu are similar to Wed, with a focus of moisture persisting over the local marine zones and coastal sites, with a slight chance of showers reaching west of I-95.

The week of rollercoaster temperatures will begin the ascent again, after bottoming out early Wed morning. Afternoon highs will still feel the grip of cold air advection, only reaching the upper 50s along and north of I-4, with low 60s elsewhere except mid 60s for the immediate Treasure Coast. Lows Thu morning rebound to the upper 40s, low 50s across the interior to mid/upper 50s at the coast, with warming trend persisting through the afternoon and the return of 70s areawide.

Friday-Monday . The next cold front is set to arrive late this week and into the weekend, as a shortwave trough pushes across the Midwest, developing into a closed sfc low over the Ohio River Valley. Locally, onshore winds will shift southerly on Friday, becoming northwesterly behind the front Saturday afternoon. Moisture appears to be concentrated near a developing low center at the tail of the front as it moves across the GOMEX, thus leading to PoPs of 20-30% Friday/Fri night. Weekend will remain rain free as dry air quickly sweeps in behind front, with temperatures remaining at to slightly below seasonal values in the mid/upper 60s for highs and upper 40s/low 50s for morning lows.

AVIATION. VFR conditions with marginal MVFR cigs that will range between 030-035. After sunrise, winds will increase from the NNW to 10-15 kt and gusts up to 25 kt across the interior sites while coastal terminals could gust up to 30 kt. After sunset, gusts should decrease inland while remaining to 20-25 kt along the coast through the night.

MARINE.

Today-tonight . Winds will rapidly increase this morning as the pressure gradient tightens from the coastal waters of the Carolinas towards south Florida. This needed for the Small Craft Advisory that is in effect this morning to be upgraded to a Gale Warning for this afternoon and through the night. Winds will pick up late this morning and peak tonight to 30 knots with gusts up to 40-45 knots. With such a strong wind flow, seas will also increase rapidly today, building from 7 to 10 feet this morning to 9 to 13 feet by early evening and up to 15 feet late tonight.

Wednesday-Friday . Extended period of hazardous marine conditions will last through the remainder of the week, with a long-duration Small Craft Advisory likely necessary through at least Friday. A developing sfc low off the east central FL coast will allow for a tightening pressure gradient and northeasterly wind surge over the local waters. N/NE winds of 25-30 kts with gusts to gale force will last through midday Wed, very slowly diminishing to 15-20 kts by Thu morning. Seas will persist at 10-12 ft nearshore and up to 15-16 ft in the offshore waters, becoming 7-10 ft by Friday morning.

FIRE WEATHER. Tightening pressure gradient over the region will increase winds up to 15 mph this afternoon through Wednesday. Behind yesterday's cold front passage, much cooler and drier air will sink across the area, leading to min RH values of 38-40% across a portion of the interior this afternoon, however, remaining above critical thresholds.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
