Area Forecast Discussion National Weather Service Jacksonville FL 956 AM EST Fri Feb 21 2020

UPDATE.

Cold and blustery is a good summary for today with strong northerly winds and cold advection. Furthermore, overcast skies to start off making for big changes in feels-like temperatures compared to 2 days ago when we had highs in the lower 80s. Temps today will struggle through the 40s to the lower 50s as clouds will be slow to clear, though timing these clouds suggest we'll see some breaks in northeast FL around the 18z-22z time frame. Southeast GA seeing some sun now over Appling and Wayne counties. Based on the current temp readings and guidance have shaved off about 1-2 degrees for highs today. Any lingering light rain areas have diminished so will tweak POPs down a bit for the southeast zones where radar and obs show light rain/drizzle. Wind obs show sustained at 20-25 mph and gusts of 36 mph along the coast. Wind advy remains in effect there. Based on latest guidance and consensus have upgraded the freeze watch to a warning. Only areas that may escape a freeze may be the sern portion of Clay, Bradford and Alachua counties.

MARINE. Current forecast on track. Only slight change was to increase wave heights a bit based on Fernandina Beach and St Augustine buoys reporting seas of 9-12 ft. Used new 06z NWPS run to modify current wave grids. Surf cams suggest very hazardous and high surf at area beaches.

Water levels along the northeast FL coast reporting action and minor flood stage at the high tide this morning so will leaving coastal flood advisory in effect. Next high tide around 7-8 pm tonight probably not as high given astronomical tides will be several tenths of a foot lower.

PREV DISCUSSION [607 AM EST].

NEAR TERM [Through Tonight].

Regional 06Z surface analysis shows a cold front draped across Central Florida this morning, with strong north winds in its wake. Local winds this morning are around 15-25 mph, with gusts to 30-40 mph. Isentropic lift has allowed low clouds and light rain to develop across the region, but these conditions are expected to improve through the morning hours as the axis of lift and cold front continue to push further southeast. Gusty conditions on the other hand will continue into the overnight hours. The dry, cold air mass moving in will keep highs this afternoon in the low-mid 50s, but with winds of 20-25 mph and gusts up to 40 mph, it will only feel like it's in the mid 40s to low 50s. Overnight, it's looking like southeast Georgia and northeast Florida will see a freeze, with lows in the upper 20s to low 30s. Further south/east in north- central Florida and along the immediate Florida coastline, lows will be in the mid 30s. Thanks to winds lowering overnight (particularly inland), a wind chill advisory looks unlikely.

SHORT TERM [Saturday Through Sunday].

High pressure will build north of the region through the weekend with northeast winds developing and slowly moderating temps, although Highs still below normal around 60 degrees on Saturday under Mostly Sunny skies, then rebounding closer to normal levels in the 60s/lower 70s on Sunday. Main hazard over the weekend will be potential for some areas of frost over inland SE GA and inland North FL along the I-10 corridor as temps fall into the lower to middle 30s there, with upper 30s into the 40s elsewhere. Milder temps in the 40s/50s for Sunday Night as sky cover increases and winds become Southeast overnight, some patchy fog possible but too early to include in the forecast.

LONG TERM [Monday Through Friday].

Monday thru Wednesday . High pressure pushes quickly offshore into the Atlc and the next slow moving frontal boundary will sink Southeast into the region with numerous to widespread showers by Monday Night and continuing through Wednesday with a few periods of showers and isolated thunderstorms. Temps generally above normal with Highs into the 70s and Lows in the 50s and with the slow movement of this feature and several rounds of rainfall, long range models are suggesting widespread 1"-2" rainfall amounts with locally higher 3"-4" totals possible.

Thursday . Models in general agreement for much cooler temps with Highs only in the 50s and a late winter light freeze possible over inland areas for Thursday Night.

AVIATION. [Through 12Z Saturday]

MVFR/IFR cigs will gradually improve through 15-17Z. Strong northerly winds today will be around 12-15 kts this afternoon with gusts to 24-34 kts, especially at sites along the coast. Winds will become more easterly overnight and should begin to lower a little after sunset.

MARINE.

Strong northerly winds today of 25 to 30 knots with gusts to 40 knots will become more northeasterly overnight. Winds and wind gusts gradually falling below 34 knots through the early morning hours on Saturday, but winds will remain around 15 to 20 knots through Saturday night. Conditions will only briefly fall below small craft advisory conditions though, with winds from the south to southwest increasing again on Monday ahead of our next frontal system.

FIRE WEATHER.

Humidities expected to fall into the 25 to 30 percent range Saturday afternoon across inland Southeast Georgia but winds are expected to fall to around 10 mph so Red Flag headlines are not expected at this time.

HYDROLOGY.

Flooding continues along the Altamaha River from near Charlotteville, GA over to Everett City, GA. No significant rainfall is forecast for the next several days to aggravate this flooding, though it will take a while for river levels along the Altamaha to lower.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
