Area Forecast Discussion National Weather Service Jacksonville FL 859 AM EDT Sat Apr 4 2020

UPDATE.

Forecast remains on track. Weak troughing oriented northwest to southeast near the GA and SC coasts will slide southwest today and early tonight. Weak high pressure over srn AL will drift southward through the day. These two features combine to produce a weak pressure gradient and enough for an early afternoon Atlantic coast sea breeze. The sea breeze will push inland with the aforementioned trough over southeast GA. Air mass remains much too dry (dewpoints drop into the 40s today) for precip despite the sea breeze and sfc trough. Passing mid and high clouds today but more than enough sun to bring highs into the lower and mid 80s for inland areas and upper 70s to around 80 at the coast.

MARINE.

West-northwest flow around 5-10 kt will shift around to the northeast and east this aftn and early evening. Seas currently reported at area buoys 1.5 to 2.5 ft with long periods of about 12 seconds. Only slight tweaks to the forecast expected for the morning update.

PREV DISCUSSION [747 AM EDT].

NEAR TERM [Through Tonight].

Warming trend continues with mostly dry conditions today and into the evening, then a low chance of showers across NE FL after midnight tonight focused along the coast generally south of St. Augustine extending inland toward the St. Johns River basin from Palatka toward the Ocala NF through sunrise Sunday morning.

A dry backdoor cold front near the GA/SC state-line early this morning will slide SSW across SE GA this morning and then begin to stall and linger across north-central Florida into the afternoon and overnight. Surface high pressure will nose southward down the SE Atlantic coast as an elongated lobe of PVA streams overhead from the Gulf Coast region. Isentropic lift will increase along the north-central FL coast after midnight as the short wave trough approaches from the west and overrides low level easterly flow on the northern side of the frontal zone across north-central FL. Advertised a low chance of coastal showers moving onshore generally after 4 am Sunday morning along the St. Johns and Flagler county coasts toward the St. Johns River Basin through sunrise. Elsewhere, mostly dry conditions are expected with some patchy fog potential along and north of the boundary.

Temperatures will further warm today by a few degrees with highs above normal in the low/mid 80s inland to the mid/upper 70s toward the Atlantic coast. Lows tonight will also moderate 5-10 deg warmer and trend above normal as clouds thicken with minimums ranging from the mid 50s to near 60 inland to the mid/upper 60s toward the Atlantic coast under onshore flow.

SHORT TERM [Sunday Through Monday].

On Sunday, a shortwave moves eastward across the Gulf coast bringing scattered showers to the area. High pressure builds in behind this impulse leading to dry conditions on Monday. Due to overcast skies and showers, temperatures cool slightly on Sunday with highs in the upper 70s to low 80s. Highs warm to the low to mid 80s on Monday.

LONG TERM [Tuesday Through Friday].

Surface high pressure off the Atlantic coast and upper ridging across the southern Gulf of Mexico prevail through mid-week. A series of shortwaves will propagate along the northern periphery of the ridge and move through the Southeast. Models are in better agreement with this past 00Z run bringing rounds of showers and storms to the area through the week. An isolated thunderstorm will be possible through the week with the highest potential of thunderstorm development on Wednesday. West-southwesterly flow develops leading to a warming trend. Highs will warm into the upper 80s to around 90 and lows into the mid to upper 60s by midweek.

AVIATION. [Through 12Z Sunday]

Light and variable winds or west-northwest near 5 knots through midday. Winds shift around to the northeast and east for the coastal TAFs as a weak boundary settles southward across the terminals into the evening. Winds diminish inland this evening and remain slightly elevated near the coast. Dry conditions will prevail today as mid and high clouds stream over the region from the west through the evening. Lowering cloud bases expected late tonight but still prevailing VFR. Low chance of a couple of showers early Sunday morning, just beyond this forecast period.

MARINE.

A weak trough will settle south across the local waters today shifting winds from northwest this morning to easterly into the afternoon. High pressure will build northeast of the waters this afternoon and east of the Florida peninsula Monday. The high will shift farther offshore of south Florida Tuesday into Wednesday as a surface front settles across Georgia. Long period swells will increase from the northeast tonight and will persist through midweek creating marginal advisory conditions over the outer Florida waters beginning Sun and persisting through Tue.

Rip Currents: Moderate risk of rip currents today. Potential for high risk NE FL beaches Sunday with continued moderate risk for SE GA.

FIRE WEATHER.

Dry conditions with near critical to critical low RH values (25-35%) across the interior expected today. However, light winds will prevent inland locations from reaching any criteria. Light and variable winds prevail but coastal winds increase and shift to northeasterly in the afternoon with the seabreeze. Moisture will increase on Sunday and scattered showers and isolated storms are possible across the area. Easterly winds will increase to 10-15 mph at the coast and remain around 5 mph across the interior on Sunday.

HYDROLOGY.

Rises along the Altamaha River over the next few days with Minor Flooding occurring at Baxley expected to crest Sunday. Other locations along the basin are expected to remain below Flood Stage.
