Marine Weather and Tides
Version 3.4 |
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. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

AVIATION. [Through 00Z Wednesday]
Prevailing VFR conditions early this evening under high cirrus, but will start to see lower clouds begin to edge inland from the WSW. High confidence of IFR to VLIFR restrictions tonight with low stratus and advective fog moving inland from the Gulf Coast region impacting GNV after 03Z and extending eastward toward VQQ/JAX through 09Z under light SSW winds. Low stratus is expected to advect toward coastal terminals through sunrise with restrictions of MVFR to IFR advertised at this time. Low clouds and fog will erode near the Atlantic coast first between 12-14Z Tue morning with slower erosion over inland areas between 12-15z. Prevailing VFR expected by 16Z with low cumulus in the afternoon under warm and breezy at times southerly flow. Expect a stronger west coast sea breeze in the afternoon with a weaker east coast sea breeze likely lingering just along the coast which may back winds more SSE at SSI and SGJ but may not make much inland progress toward CRG.
PREV DISCUSSION [320 PM EST].
NEAR TERM [Tonight through Tuesday]. Warm and dry conditions will continue. Scattered showers to the west in an area of moisture convergence should fade this evening as instability weakens. With sw flow increasing just above the surface, models indicate advection fog from the Gulf coast across se Ga/ne Fl late tonight. Expect areas of dense fog over inland areas after midnight . reaching east coast counties around sunrise. Fog will linger until mid-morning. Warm southwest winds will push temperatures into the lower 80s Tuesday afternoon with record highs possible.
Record Max Temps for December 10th . JAX 82/1961 . GNV 84/1972 . AMG 82/1972 . SSI 81/1997 . CRG 83/2012
SHORT TERM [Tuesday night through Thursday Night]. A cold front will slowly move se into se Ga Tuesday night reaching ne Fl Wednesday morning as an upper trough moves into the se. Showers will develop along and behind frontal boundary with isolated thunderstorms possible over ne Fl Wednesday afternoon. The front will be south of the area Wednesday night through Thursday night as strong high pressure builds in from the north. A tight pressure gradient will produce gusty ne winds especially at the coast. The chance for rain will continue with higher chances along the east coast due to a strong ne flow. Temperatures will be close to December averages.
LONG TERM [Friday Through Monday]. A stronger upper trough will approach from the lower Ms River Valley on Friday producing surface cyclogenesis over the north central Gulf. This will bring increasing rain chances with thunderstorms Friday and Friday night with the low moving ne across the Fl panhandle and south Ga. This system will lift ne of the area on Saturday with drier air advecting in through Monday. Temperatures will be at or above normal through the period.
MARINE. Southwest winds will continue through Tuesday with weak afternoon seabreezes near the coast. A cold front will push across the waters on Wednesday and then stall south of the waters before lifting back north at the end of the week. Small Craft Advisory conditions will likely develop Wednesday night through Thursday night as the pressure gradient tightens with strong high pressure building to the north. Occasional to frequent Gale force gusts are also expected. Scattered to numerous showers are expected with isolated thunderstorms possible Tuesday night through Friday night.
Rip Currents: Moderate risk of rip currents at northeast Florida and southeast Georgia beaches through Tuesday.
