Version 3.4 |
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion National Weather Service Jacksonville FL 917 PM EDT Mon Jun 1 2020
UPDATE.
Low level easterly flow will continue through the night while drier airmass will filter in aloft from the Northeast. This will keep partly to mostly cloudy skies in place, but isolated shower activity will be limited to pushing inland across Flagler, Putnam and Eastern Marion counties at times but mostly just sprinkles are expected and not much in the way of measurable rainfall. Drier airmass pushing into inland SE GA at the surface will allow for some min Temps falling into the lower to middle 60s, while mainly upper 60s expected for inland NE FL and lower/middle 70s for the Atlc Coastal Areas in the lingering breezy onshore flow at the coast at 10-15 mph. Breezy Easterly flow at 15-20 mph will resume across the region again on Tuesday with drier airmass aloft limiting shower activity to just some scattered diurnal showers along the I-75 corridor of inland NE FL during peak heating. Wind gusts will reach the 25-30 mph along the Atlc Coastal Counties but not quite as strong as they were today. Max Temps in the lower 80s for the Atlc Coastal Counties to the mid/upper 80s over inland areas.
PREV DISCUSSION [729 PM EDT].
NEAR TERM [Through Tonight].
Isolated showers with a slight chance of developing into a thunderstorm, are moving across the forecast area this afternoon from out of the east ahead of the encroaching backdoor front. Convective developments and easterly gusty winds will start to wind down around sunset, with inland areas calming while maintaining wind speeds of about 15 mph near the coastline. Overnight low temperatures are expected to drop down into the mid to upper 60s for inland areas and in the lower 70s for locations along the coast, near the St Johns River, and for portions of northern central Florida. No significant fog developments are anticipated tonight or tomorrow morning.
SHORT TERM [Tuesday Through Wednesday].
Upper level ridging will persist through Tuesday and for part of Wednesday with mostly dry weather expected for southeastern Georgia and a portion of northeastern Florida. Possibility of isolated developments on Tuesday with the highest chances for showers and storms occurring over northern central Florida. Ridging will start to recede off towards the northeast late Wednesday as flow shifts about to become more southerly resulting in increased moisture levels and increased chances for overnight convection as a shortwave trough moves in from out of the west. Temperatures will continue to follow the warming trend with daily high temps reaching into the upper 80s and lower 90s for inland areas and in the mid 80s along the coast by midweek, with overnight low temperatures in the mid to upper 60s for inland areas and in the lower 70s for coastal areas.
LONG TERM [Thursday Through Monday].
A mid level low pressure system moving northward will merge with a shortwave trough near the panhandle and then progress its way eastward, crossing over the forecast area early Thursday morning. This will be the start of a multi-day wet weather pattern with showers and storms anticipated into Friday and Saturday with a potential for locally heavy rainfall. Conditions will become drier and more stable on Sunday and Monday as upper level ridging starts to build in over the area. Initially lower temperatures on Thursday and Friday, with high temps in the lower 80s, due to cloud cover and rain will warm in the latter half of the weekend and into next week as cloud cover becomes less abundant, with high temps rising into the upper 80s. Overnight low temps will range between the upper 60s and lower 70s during this period.
AVIATION. [Through 00Z Wednesday]
Shower activity has faded at TAF sites and expect mainly SCT to BKN clouds in the 2000 ft to 4000 ft range through the period with gusty East winds at 12-17 knots with gusts of 20-25 knots at times. Some diurnal decrease in winds is expected after sunset tonight, then increase once again on Tuesday during the mid morning hours. For now have just placed some TEMPO MVFR CIGS this evening at GNV, but will have to keep an eye out for possible MVFR CIGS at SGJ if more onshore showers develop.
MARINE.
High pressure will continue to build in from the north with a surge of northeast winds and building seas. A small craft advisory is in effect through late tonight for the nearshore waters and into Tuesday afternoon for the offshore waters. Winds will subside late Tuesday as high pressure moves east of the area with elevated seas persisting through Tuesday evening. The high will continue moving east of the area waters Wednesday into Thursday with a chance of thunderstorms returning late in the week over the waters as weak low pressure approaches the region from the southwest.
FIRE WEATHER.
High pressure will continue to build in from out of the north today with the northeasterly winds bringing scattered showers and strong onshore winds at 15 to 20 mph with higher gusts throughout the afternoon, with the strongest winds occuring along the coast. Wind speeds will start to uniformly wind down around sunset. Tuesday is expected to be mostly dry with breezy easterly winds.
