DISCUSSION.

. Areas of Dense Fog Possible Tonight .

. Hazardous Marine Conditions Develop By Wednesday Evening .

. Locally Heavy Rainfall Possible Wednesday night into Friday .

Rest of Today . High pressure ridge axis centered on the southern half of the FL peninsula has resulted in mostly south to southwest flow in central Florida today. This has allowed temps to skyrocket, with a record high set at Melbourne (86F, breaking old record of 85F last set in 2013), and a tie at Sanford (85F, last set in 2013). The sea breeze has developed from central Brevard south to Martin County, but the bigger southerly component to the winds has prevented significant inland progression. Overall, hot conditions this afternoon as highs climb into the mid 80s. High resolution models still hinting at isolated showers this afternoon, thus kept in a 20 percent chance of rain across the area.

Tonight . Increase in low level moisture expected as a cold front begins moving into the Florida peninsula. Light southerly winds will become calm in most places. The combination of light winds and abundant moisture will lead to fog development late tonight over much of east central Florida. Dense fog is possible, especially across the rural interior. Motorists are urged to allow extra time for the morning commute, and slow down when encountering areas of fog, leaving plenty of space between you and the vehicle in front. Extremely mild temps overnight with lows in the mid 60s, except near 70 degrees along barrier islands, which is about 10 to 15 degrees above normal for mid December.

Wednesday . A strung out vorticity axis emanating from the tail end of a northern stream mid level short wave trough to push across the Southeast CONUS and FL panhandle through Wednesday night. A surge of north winds accompanying the cold front will move through the area quickly, starting across the north around sunrise, through the Space Coast around noon, and Treasure Coast by mid afternoon. Should see isolated to scattered showers developing along and ahead of the front. Lower rain chances along and north of I-4 (20 percent) as the front should already be south of there by mid morning, and higher south (40-50 percent).

A dense overcast deck of clouds to spread south as the front moves in, keeping afternoon temperatures in the mid to upper 70s (near normal) from Melbourne to Kissimmee northward. Treasure Coast heats up into the low 80s during first half of the day. Model sounding analysis indicate 500mb temps around -9C to -10C and 700mb around 6C, which could be supportive of lighting but confidence is too low to include in the forecast at this time.

Wed Night . Cold front over central FL will drift down to the Lake-O/Jupiter Inlet vicinity where it will stall and washout. NE wind surge will work its way into the Treasure Coast by midnight as the front's trailing moisture band stalls acrs the CWA, eventually saturating the H100-H85 lyr. Aloft, the right rear quad of a 70KT jet streak will provide some upr lvl evacuation. A broad area of mid lvl omega is present as well, but weak and disorganized . mid lvl vorticity not present.

Strength of the onshore flow diminishes rapidly thru the H85-H70 lyr, but overall mean flow thru H100-H70 lyr coupled with the near saturation of the H100-H85 lyr will require PoPs areawide. The shras will be low topped in nature as a mid lvl subsidence inversion remains in place, but lcl heavy rain will be possible in the vicinity of the frontal boundary due to enhanced sfc convergence coupled with coastal convergence. PoPs will be split from 40-50pct along he coast to 20pct west of the FL Turnpike. Little in the way of cool air advection, especially with the onshore flow. Min temps in the U50s/L60s along and north of I-4 . U60s/L70s over the Treasure Coast/Lake-O region. Thu-Fri . The NE wind surge will continue thru the day Thu and into Thu night as the post frontal ridge lifts off the Mid Atlc Coast into the NW Atlc. The H100-H70 mean flow will steadily veer from NE so SE Thu night into Fri, gradually diminishing as the ridge pulls into the open Atlc. Meanwhile, a short wave trof off the Pac coast will race eastward as a 170KT zonal jet streak over E Pac races acrs the country. As this streak noses it way into the W GOMex, it will induce a weak sfc low that will pull the remnant frontal trof/moisture band back to the north as a weak warm front as winds veer thru due south.

WX pattern will remain unsettled to end the work week as SW flow thru the H85-H50 lyr generates a source of mid lvl (isentropic) lift acrs central FL. Airmass will gradually saturate from sfc to cig with PWat values increasing to arnd 1.50" by midday Thu. Meanwhile, an H30-H20 jet streak will place the peninsula under its RR quad, SW mid lvl winds maintain isentropic lift, a mid lvl thermal trof will cool H50 to -11C/-12C, and the front provides a source of sfc convergence.

Will keep slght chc of thunder in the fcst due to the cool temps and dynamic support aloft . limiting factors will be max temps AOB 80F due to high and thickening cloud cover. Local heavy precip (2-4"+) will be possible along/near the east coast due to training shras along and near the frontal boundary. Sct/chc PoPs will show a 30/40 interior 40/50 coastal split. Max temps generally M/U70s, min temps M/U60s.

Saturday-Monday . (prev disc) Mid level troughing over the central-eastern CONUS flattens, allowing the flow to become zonal locally. A few lingering showers Saturday (mainly early) will exit the region, with a drier (but still mild/warm) air mass taking hold into early next week. Maxes in the 75-80F range with mins in the U50s-L60s most areas.

AVIATION. VFR conditions prevail through late evening. Mostly dry, though a few light showers will be possible through the late afternoon. Late tonight, expect fog to develop across much of the area, with areas of dense fog and/or low stratus likely after 11/10Z. Have included TEMPO groups for LIFR visibility and ceilings, though periods of VLIFR conditions are possible too. As a front begins to enter the area, may likely be socked in with MVFR/IFR ceilings for much of the day tomorrow from ISM-TIX northward.

MARINE.

Today-Tonight . South to southwest winds over the local waters to continue through tonight as high pressure ridge starts to pull away from the area. Expect winds to increase to near 15 knots overnight, while seas remain 3-4 feet nearshore and 4-5 feet offshore.

Wednesday . Hazardous boating conditions develop over the waters starting late Wednesday afternoon as a cold front pushes through the region. West winds around 10 knots over the waters to start the day will increase through the afternoon. For the Volusia coastal waters, a Small Craft Advisory will go into effect late afternoon as north winds increase to 20 knots as seas build 5-7 feet nearshore and 7-11 feet offshore.

Wed Night . Hazardous boating conditions dvlpg as the cold front pushes thru central FL and stalls in the vicinity of Lake-O/Jupiter Inlet. Winds bcmg a moderate to fresh NE breeze over the nearshore waters . fresh to strong offshore leg. Seas building to 6-8FT nearshore and 8-12FT offshore. Shras likely south of Sebastian Inlet, chc of shras northward. SCA will be needed by this time.

Thu-Thu Night . Hazardous boating conditions continue as the wind surge slowly diminishes. Winds a fresh to strong E/NE breeze early in the day, decreasing to a moderate to fresh E breeze by sunset, then a gentle to moderate E/SE breeze overnight. Seas will be slow to subside as the easterly fetch will extend well into the open Atlc and push a large easterly swell into the east FL coast. Seas 6-8FT nearshore and 8-12FT offshore thru the day, subsiding to 5-7FT nearshore and 7-9FT offshore by daybreak Fri. Shras likely/slgt chc of tsras.

Fri-Fri Night . The wind surge will diminish by daybreak as the front retreats northward, but seas will remain hazardous as the swell train slowly dampens out. Winds bcmg a gentle to moderate E/SE breeze by sunrise, light to gentle S/SE breeze by sunset, veering to SW by daybreak Sat. Nearshore seas 5-7FT at thru the day, subsiding to 4-6FT overnight . offshore seas 7-9FT thru the day, subsiding to 5-7FT overnight. Wind waves bcmg choppy with the dvlpg offshore breeze. Sct-nmrs shras/slgt chc of tsras.

Sat-Sat Night . SCA seas ending by daybreak Sat but conditions will be rough as a developing low over the GOMex pull a new cold front through central FL. An offshore breeze will prevail thru the day . gentle to moderate breeze nearshore and moderate to fresh offshore . veering from SW at daybreak to due W by sunset, then diminishing to a light to gentle N/NW breeze overnight. Seas 4-5FT nearshore and 5-6FT offshore, subsiding to 3-4FT nearshore and 4-5FT offshore by sunset. Chc of shras.

Sun-Mon . Somewhat marginal conditions as high pres builds acrs the FL Peninsula and into the W Atlc. Winds a light to gentle N breeze at daybreak Sun, veering to E/NE by sunset, then bcmg a gentle to moderate E/SE breeze by daybreak Mon. Diminishing NE swells will continue to enhance lcl wind waves . seas 3-4FT nearshore and 4-5FT offshore Slgt chc of shras Mon. chc/slgt chc of shras Mon night.
