Area Forecast Discussion National Weather Service Jacksonville FL 317 PM EDT Thu Oct 28 2021

NEAR TERM [Through Tonight].

The potent cold front extending from a deep, occluded surface low spinning over southern Missouri has pushed eastward across the Florida panhandle early this afternoon and is now encroaching on our western zones. The strong pre-frontal squall line, which traversed across northeastern FL south of I-10 this morning and early afternoon, has now shifted eastward into the Atlantic waters. While strong squall line cross areas south of I-10, areas to the north never had a chance to destabilize today due to the leading stratiform rain which pushed across the lifting warm front this morning. A beneficial and widespread rainfall footprint with 1 to 2" estimated from radar in the stratiform region while more localized amounts of similar magnitude fell with the more intense squall line segments; however, nearly the entire region received at least 0.50" of rainfall today. With the squall line tracking into the coastal waters, the remaining portion of the Tornado Watch has been canceled.

While the severe thunderstorm threat has diminished, scattered showers and isolated thunderstorms are still possible through the remainder of the afternoon as the trailing cold front presses toward the Atlantic. Widely scattered light showers are expected overnight, primarily across northeast FL with weak post-frontal troughing and forcing from the stationary upper drifting across the area.

Breezy southwest winds tonight will keep portions of northeast FL in the low 60s tonight while cooling post-frontal air allows temps to fall into the mid and upper 50s elsewhere.

SHORT TERM [Friday Through Saturday Night].

Deep cutoff upper low will dominate the eastern seaboard through Saturday night before it is shunted northeastward by an upstream trough Sunday. Showery conditions expected Friday with southwesterly flow at the base of the low and mid trough axis. Moisture will be shallow and PWATs will likely be below an inch, so precip should be light with any activity Friday. With little translation of the low to the north, gradients will remained pinched through Friday leading to continued gusty southwest to west winds, featuring afternoon gusts up to 30 mph. Drier west northwest flow will prevail through Saturday as upper trough begins to lift northeastward. Strong cold air advection will bring the coolest temps this season. Drastically cooler afternoon temps are expected through the weekend, with highs in the mids 60s across SE GA and low to mid 70s across NE FL.

LONG TERM [Sunday Through Thursday].

High pressure will build from the northwest Sunday through Tuesday shifting prevailing flow from northwesterly to northeasterly. With enhance convergence along a stalled inverted trough over the Atlantic, there will be increasing chances for coastal showers with onshore steering flow by Tuesday. Another cold front will approach from the northwest on Wednesday and may press through Thursday. As onshore flow develops, temperatures will gradually warm toward typical climo readings by next week.

AVIATION. [Through 18Z Friday]

IFR conditions will prevail through around 20Z at SSI and SGJ as showers and thunderstorms cross these terminals and move offshore. Otherwise, VFR conditions will prevail at the remainder of the northeast FL terminals through around 20Z. Another round of showers and possibly an isolated thunderstorm could impact the regional terminals between around 20Z and 06Z tonight, although confidence was too low to include VCTS at this time. This activity would bring brief periods of MVFR conditions to the terminals. A more extended period of MVFR ceilings around 2,000 feet is possible overnight after 05Z through around sunrise on Friday. However, confidence was too low to include anything other than scattered ceilings, with more confidence for broken ceilings around 4,000 feet. VFR conditions should then prevail area-wide by 15Z Friday. Mainly southerly surface winds will continue to strengthen through around 22Z this afternoon, with sustained speeds increasing to around 15 knots with frequent gusts of 20-25 knots. Sustained southwesterly surface speeds should subside to 5-10 knots after 00Z, with another burst of winds increasing to 10-15 knots after 05Z tonight. Breezy west-southwesterly surface winds are forecast throughout the day on Friday.

MARINE.

A strong cold front will continue east and push across the local waters tonight. Prefrontal winds have increased to small craft advisory levels this afternoon. Winds will strengthen further behind the cold front, with gusts 30-35 kts. With little movement of low pressure to the north, these gusty offshore winds will last through Friday in the nearshore waters and Friday night for offshore waters. Winds begin to ease up over the weekend, however, Caution Level winds will likely persist through most of Saturday along with elevated seas offshore. Surface high pressure will build eastward toward the Atlantic early next week, turning winds onshore Monday and Tuesday.

Rip Currents: Moderate to marginally High Risk on Friday due to elevated surf and weak southeasterly swell. Lowering surf will reduce risk to Moderate on Saturday.

FIRE WEATHER.

Severe weather threat has moved east of the area this afternoon. Cold front will shift eastward off the coast this evening with scattered showers possible along it. Spotty showers will persist behind the front tonight, though these will not produce much rainfall. Winds will remain from the west and gusty on Friday with strong low pressure to the north. Dispersions will be marginally high on Friday with more widespread high dispersion expected on Saturday. Winds will begin to turn northerly as they ease over the weekend with high pressure building from the west.

HYDROLOGY.

Several hours of stratiform rain brought widespread areas of 1 to 2" across southeast GA while locally heavy rain associated with the squall line brought an estimated 2 to 3" of rain across the Suwannee Valley. Shower activity will continue along and behind the cold front but rainfall amounts will be minimal.
