Version 3.4 |
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it. 8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue. 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. |

AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 300 Pm Edt Wed Sep 23 2020
Synopsis.. High pressure centered along the carolina coast will move eastward and will strengthen near bermuda on Friday. Seas will continue to slowly subside, but will remain at small craft advisory levels through Thursday. Meanwhile, the remnants of tropical storm beta will move northeastward through the lower mississippi valley tonight and will then weaken over the tennessee and southern appalachians on Thursday night and Friday. This weather pattern will result in gradually increasing southeasterly winds beginning tonight, followed by winds subsiding on Saturday night and Sunday ahead of an approaching cold front. Showers and Thunderstorms will increase in coverage over our local waters from Friday through the weekend. A series of dry cold frontal passages are then expected early next week.

Area Forecast Discussion National Weather Service Jacksonville FL 156 PM EDT Wed Sep 23 2020
AVIATION. [Through 18Z Thursday]
VFR conditions will prevail at the regional terminals through at least 06Z. Easterly surface winds will increase to 5-10 knots by 19Z. Periods of MVFR visibilities will be possible at VQQ and GNV after 07Z, but confidence was too low to include in the afternoon TAFs. Southerly surface winds will develop shortly after sunrise on Thursday, with sustained speeds increasing to 5-10 knots by 14Z.
PREV DISCUSSION [1042 AM EDT].
NEAR TERM [Through Tonight].
Upper ridge will shift south allowing clouds to funnel into the region from the remnants of Beta to our west near the southern Mississippi valley. At the surface, high pressure and a dry airmass (PWATs less than an inch) will lead to a rain free day. Temperatures today will be slightly warmer with a weaker onshore flow, however, cloudy conditions will keep highs in the upper 70s to mid 80s. Lows tonight will range from the low 60s to low 70s.
SHORT TERM [Thursday Through Friday].
Thursday . High pressure pushes further east into the Atlc and southerly steering flow will pump up Max Temps to above normal levels in the mid/upper 80s, while drier air aloft will limit any shower activity during the afternoon hours to only isolated across inland SE GA and along the weak SE Atlc sea breeze front along the NE FL coast.
Thu Night . Moisture levels will continue to slowly increase with a more moist mid level SW flow aloft and a few showers and storms will be possible across inland SE GA and the Suwannee Valley as well as over the Atlc Coastal Waters, but still many locations remain dry across NE FL through the night with abundant clouds keeping the overnight lows much milder in the lower 70s inland and mid to upper 70s along the Atlc Coast.
Friday and Friday Night . Deeper Tropical Moisture remnants from Beta finally push over top of the ridge and into the region and a combination of daytime heating and Precipitable Water Amounts (PWATs) around 2 inches or so should be enough to trigger scattered to numerous showers with a few embedded storms by the afternoon and evening hours, with leftover isolated showers Friday Night. Mild Southeast Flow will push Max Temps into the mid/upper 80s once again and while severe storms are not expected, some brief heavy downpours will be the main threat from convection.
LONG TERM [Saturday Through Tuesday].
Sat/Sun . Continued warm/humid with above normal temps for late Sept with highs in the upper 80s/near 90 degrees and muggy overnight lows in the 70s. Still enough lingering moisture with PWATs around 2 inches to continue the threat of scattered showers and isolated storms during the afternoon and early evening hours, but certainly not a weekend washout. Weak flow aloft will limit any strong convection with just brief heavy downpours the main impact from the weekend convection.
Mon/Tue . A weakening cold frontal boundary will push through the SE US and settle into the NE FL/SE GA region early next week. Not much dynamics assocd with this feature so basically just a new injection of moisture into the region which will continue the warm/humid conds with scattered showers and isolated storms, mainly during the afternoon/early evening hours. Above normal temps continue with highs in the upper 80s/near 90 and lows in the 70s. Still some uncertainty if the frontal boundary gets enough push to allow for some drier airmass to reach inland SE GA by the Tuesday time frame, so still only low to moderate confidence in forecast for this time period.
MARINE.
High pressure centered along the Carolina coast will move eastward and will strengthen near Bermuda on Friday. Seas will continue to slowly subside, but will remain at Small Craft Advisory levels through Thursday. A Small Craft Advisory will remain in effect for the near shore waters adjacent to northeast FL and for the offshore GA waters through tonight. Seas will remain at Small Craft Advisory levels for the offshore FL waters through at least Thursday evening. Meanwhile, the remnants of Tropical Storm Beta will move northeastward through the lower Mississippi Valley tonight and will then weaken over the Tennessee and southern Appalachians on Thursday night and Friday. This weather pattern will result in gradually increasing southeasterly winds beginning tonight, followed by winds subsiding on Saturday night and Sunday ahead of an approaching cold front. Showers and thunderstorms will increase in coverage over our local waters from Friday through the weekend. A series of dry cold frontal passages are then expected early next week.
Rip Currents: Long period ocean swells and elevated seas will keep a high risk in place at all area beaches through Thursday.
HYDROLOGY.
A Coastal Flood Warning remains in effect through this afternoon along the upper St. Johns River basin to the south of downtown Jacksonville, where water remains trapped after four full days of strong onshore winds. Astronomically high tides will keep water levels generally in the 1.5 - 2.5 foot range above Mean Higher High Water (MHHW) during times of high tide at these locations through Thursday night before slowly falling back to near 1 foot above MHHW on Friday. Elevated tides will continue elsewhere along the northeast FL coast and the lower St. Johns River in Duval County, with levels generally reaching minor flood status during times of high tide, generally in the 1 - 2 foot range above MHHW today. A Coastal Flood Advisory remains in effect for these locations today. Tide levels at the Atlantic coast in northeast FL should then subside to around 1 foot above MHHW during the afternoon high tides from Thursday through the weekend, while water will likely remain trapped for a few more days within the lower St. Johns basin around Jacksonville, where levels will likely reach around 1.5 feet above MHHW at each high tide through the weekend.
