DISCUSSION.

. Much Colder Weather Through Tuesday Night .

. Very Hazardous Boating and Beach Conditions Redeveloping .

Current . well-advertised strong cold front about to enter Martin County early this morning. Sharp northerly wind shift along with a precipitous T/Td drop has accompanied its southward passage through the CWA. Spotty showers along and ahead of the boundary have mostly dissipated, but latest radar trends show a small threat for the next 1-2hr in Martin County, which will be covered in a pre-first period. 4AM temps ranged from the U40s across north Lake/Volusia to the U60s across Martin/Saint Lucie Cos.

Today-tonight . The front will be south of the CWA before sunrise, with strong CAA on breezy NNW to N winds continuing through tonight. Low clouds near the front will dissipate/shift south, as will high clouds across the central/south thin and shift south. Given how cold the post-frontal air mass is, expect a healthy Atlantic SCU field to start developing later today through tonight. Some of these clouds will brush the coast, perhaps even accompanied by a few ocean-effect type sprinkles along the barrier islands after sunset. Given both the strength and trajectory of winds behind the front, there should be a fairly large (at last 2 category) temperature range for the coastal cos.

Maxes will range from the U50s-60F far north to the U60s south. Mins in the U30s NW of I-4, with L40s southward across the rest of the interior and far western areas of the coastal counties, increasing to the 50s for the immediate Space/Treasure Coast barrier islands. Wind chill readings will drop into the L-M30s NW of I-4 for about 2-5hr late tonight.

Tue-Wed . A high pressure over the mid Mississippi valley on Tue will slowly shift east while a low pressure will start to develop along a lingering front stretching from the Atlantic towards Cuba. This two systems will interact and create a strong pressure gradient off the coast of the Carolinas. This gradient will remain through the period. On Tue night and Wed, both GFS and Euro indicate the development of another area of low pressure just northeast to the northern Bahamas. Winds over land will remain from the NNW on Tue through Wed morning. This will allow for another round of cold air advection to move from the southeast U.S. into east central FL. Temps on Tue will only climb to the mid and upper 50s for Orange and northern Brevard while lower to mid 60s for Brevard southward to Martin county. The on Tue night, we will experience the coldest night so far this season. Temps are forecast to drop to the 30s west of I-95 while coastal areas will remain in the lower 40s. But these will combine with the northerly breeze of 5-10 mph to produce wind chill temperatures of lower 30s west of I-95 from Brevard to Volusia and interior while inland Volusia, Lake and areas of Orange counties will feel below 30 degrees. These conditions will meet our local criteria for a Wind Chill Advisory, which might be necessary late Tue night into early Wed morning.

On Wed, the high pressure will be elongated over the eastern states and the low pressure northeast of the Bahamas and slowly retreating east. The local wind flow will then veer from the northeast, modifying the air, becoming more marine and temperatures will warm up. Highs on Wed are expected to reach the 60s with rain chances reaching the coastal counties. Then on Wed night, lows will drop to the 50s, with the exception of northern Lake where it could drop just below 50 and the immediate coastal communities of the Treasure Coast will remain in the lower 60s.

Thu-Sun . High pressure centered over the mid-Atlantic will dig to the south towards the FL peninsula. As a low pressure moves away to the northeast, the pressure gradient will finally relax and winds becoming easterlies. On Sat, an area of low pressure is being shown by the two main models developing over the mid-Atlantic states and lifting to the northeast along the northeast U.S. coast. A cold front will be pushed over the FL peninsula on Sat, returning NW winds to the area. Temps will start on Thu in the lower 70s, mid- upper 70s on Fri, low to mid 70s on Sat and upper 60s to lower 70s on Sun. Fri and Fri night could be times with higher chances for rain across most of east central FL ahead of the front. Loss on Thu night and Fri night will be in the 50s. Then on Sat night and after the front passage, temps will cool down to the upper 40s/lower 50s.

AVIATION. Low clouds over the southern aerodromes ranging from VFR/BKN035 north to MVFR/BKN015 will break up and dissipated through mid morning. SKC to BKN250 for most areas, however aerodromes along the coastal corridor (esp MLB-SUA) will likely be dealing with some marine SCU later today-tonight with CIGs near BKN-OVC030-035 lurking just offshore.

MARINE. Today-tonight . Winds/seas have been rebuilding rapidly behind the cold front with winds already 20-25KT and seas to 6-8FT. This trend will continue through tonight, with seas building to around 9 to possibly 10ft in the Gulf Stream as seas become fully arisen there due to 180 degree opposition of wind/current. Strong SCA conditions continue through tonight.

In addition to hazardous boating conditions, the strong northerly winds will produce building surf (up to 5ft breakers) and a strong north to south flowing longshore current. This has prompted issuance of a Beach Hazards Statement through early this evening.

Tue-Wed . As a high pressure builds over central U.S. and a low pressure develops to our east, a strong to near-gale northerly wind flow will develop over the central FL Atlantic waters, creating dangerous boating conditions. Seas of 7-9 ft on Tue will build to 9- 14 ft on Wed. The WNWAVE model brings the high seas quickly and higher than 14 ft. For now, the seas were capped at 14 ft as up and down fluctuations will depend on the location and strength of the low. Wind and seas will then start to slowly subside on Wed evening.

Thu-Fri . On Thu, as the low pressure continues to retreat to the east and away from FL, winds will decrease but seas will range 7-10 ft on Thu and 6-9 ft on Fri.

FIRE WEATHER. While RFW conditions are not anticipated, min RH values will reach the L-M40s over the interior over the next two afternoon, with U30s possible Lake and adjacent parts of western Volusia/Seminole/Orange and NW Osceola Cos. A north wind near 15 MPH is also expected.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.
