Area Forecast Discussion National Weather Service Jacksonville FL 247 PM EDT Mon Apr 19 2021

NEAR TERM [Through Tonight].

Dry weather, clear skies, and mild winds will continue on into tonight as the last remaining showers have since moved off to the south with the advancing frontal boundary. Cloud cover is expected to increase overnight and into Tuesday morning as the boundary of dry air starts to retract northward. Significant overnight fog developments are not expected. High temperatures for today will be in the upper 70s today with overnight low temperatures dropping down into the 50s for inland areas and into the 60s for areas near the coast and along the St Johns River.


SHORT TERM [Tuesday Through Wednesday Night].

Dry air associated with high pressure ridging will briefly give way to showers and storms on Tuesday as a upper level shortwave trough moves over the Florida peninsula bringing convection primarily to areas south of the I-10 corridor and to counties adjacent to the coastline as the short wave progresses across the Florida peninsula and off to the northeast. Dry weather will return on Wednesday as ridging builds back in over the forecast area, following the passage of the short wave trough. Daily high temperatures during this period will rise from out of the 70s on Tuesday up into the the lower 80s on Wednesday as clear skies return.

LONG TERM [Thursday Through Monday].

Influence from high pressure ridging over the region will begin to weaken on Friday as the center of high pressure moves off towards the northeast, shifting the prevailing flow to become more out of the southwest bringing in increased cloud cover and chance for evening showers. A trough ahead of an advancing cold front is expected to move across the southeastern US at some point during the weekend, with models currently showing disagreement as to the exact timing and placement of the trough. However, showers and potentially strong storms are anticipated for the weekend with conditions becoming more dry and stable the following week. Temperatures are expected to be relatively close to the seasonal average during this period.

AVIATION. [Through 18Z Tuesday]

VFR Conditions for the TAF sites today as the last remaining showers have moved off to the south of the forecast area. Cloud cover and low ceilings will build in from out of the south overnight and into early Tuesday morning, impacting SGJ and GNV with ceilings potentially dropping to 1K feet by midday.

MARINE.

The frontal boundary will continue to move south across the region today, with high pressure building in from out of the north. The boundary will lift back to the north overnight and into Tuesday. This boundary will slip back to the south Tuesday night. Another cold front will move southeast across area Wednesday into Wednesday night. High pressure will build to the northwest Thursday, then north northeast Friday. The high will move more toward the east Friday night as a warm front lifts northeast across area. A cold front will move southeast across region Saturday night into Sunday.

Rip Currents: Moderate Risk for NE Florida thru Tuesday. Minor Risk for SE Georgia today and Moderate Risk on Tuesday.

HYDROLOGY.

Dry weather today will help mitigate flooding concerns, but another round of rain is expected on Tuesday. Minor River flooding may still be possible along the upper Santa Fe Basin, but greatest flooding impacts will continue to be the metro areas mainly south of Jacksonville through Tuesday.
