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 753 PM EDT Sun Mar 29 2020
AVIATION. [Through 00Z Tuesday]
VFR prevails through the late evening. For late tonight and early Monday morning, chance of low cigs and fog again, with the highest confidence at GNV. VLIFR conditions appear likely for GNV, with a chance of IFR or lower for VQQ and JAX. Cigs and vsbys expected to rebound and improve to MVFR by around 13z, then to VFR around 14Z through the rest of the TAF period. Some sct-broken cumulus clouds will develop around 3000-4000 ft Monday afternoon.
Winds will become light and variable over the next few hours through Monday morning. As a weak cool front slides through early Monday morning, light low level flow will shift from west- northwest to north . becoming easterly during the Monday aftn. GNV should still see southwest-west flow Monday afternoon as the front weakens and stalls.
PREV DISCUSSION [339 PM EDT].
NEAR TERM [Through Tonight].
Deep layer ridging is in place over the FL Peninsula today and will shift eastward this evening. Locally, low level winds from the south- southwest at around 5 to 10 mph today, with an onshore seabreeze along the Atlantic coastline this afternoon. Overnight, winds will become light and variable. Record heat continues with afternoon temperatures peaking in the low-mid 90s across the area. Overnight, temperatures will remain above normal in the mid 60s, upper 60s along the St. Johns River and the Atlantic coastline. Fog is expected to develop again overnight in north-central FL and the Suwannee Valley.

SHORT TERM [Monday Through Tuesday Night].
A shortwave trough will dig into the Four Corners region on Monday, ejecting into the Southern Plains Monday night, the Southern Mississippi Valley on Tuesday, and the Tennessee Valley Tuesday night. Enhanced upper level divergence from this disturbance will help lower pressures out ahead of it, with a surface low and corresponding cold front developing Monday evening in the Southern Plains. This front will track eastward, moving into the southeast Tuesday and forecast to exit our area overnight Tuesday night. With a deepening low approaching the area, the local pressure gradient will tighten, leading to breezy conditions Tuesday before the front reaches us. Sustained winds of up to 15-25 mph, with potential gusts near 35 mph at times.
There's good model agreement on this being a progressive frontal system, and though there is some discrepancy in the exact timing, the general time frame for our area has consistently been Tuesday afternoon through Tuesday night. Plenty of moisture will be on tap for the front with models showing PW values in the 1.5-2" range, so heavy rainfall will be possible with these storms. However, with a fast forward speed, this is not expected to cause widespread flooding issues. Increasing cloud coverage ahead of the front on Tuesday could limit afternoon temperatures (to the upper 80s) and the amount of instability available, but the GFS still shows 300-800 J/kg MLCAPE advecting into the area coinciding with its timing of the front late Tuesday afternoon, leading to scattered thunderstorms. The southern stream jet will swing across north FL and south GA as this system moves through Tuesday, so deep layer shear is anticipated to be around 50-60 kts with an 850 mb jet of 40 kts. As a result, thunderstorms that develop could produce damaging wind gusts. Although there's not much directional shear, the low level wind speed shear will be around 20-30 kts, so isolated tornadoes will be possible as well.
LONG TERM [Wednesday Through Sunday].
Wed & Thu: A cooler/drier NW flow behind the front will lead to Max temps closer to climo values to start April mostly in the 70s across SE GA and NE FL to near 80 degrees across north central FL. Lows will actually fall into the 40s over interior SE GA and NE FL, otherwise lows generally in the 50s through the dry period under mostly clear to partly cloudy skies.
Friday: Surface winds veer to E to ESE direction by afternoon with a moist southwesterly wind aloft starting to prime the mid to upper level of the atmosphere. There may be a weak vort lobe swinging through SE GA Friday afternoon. There may be some sprinkles or virga over interior SE GA will drier low levels while moisture increases between 700-250 mb with moist SWLY flow aloft. Not enough confidence for wetting rains. Temperatures will modify to the upper 70s to lower 80s.
Saturday and Sunday: There is not great agreement with long range global models at this time frame. On Saturday, high pressure will reside offshore to our east or northeast allowing moisture return in the SSELY flow ahead of next shortwave aloft. This pattern can possibly yield isolated to widely scattered showers with an embedded and isolated storm on Saturday. On Sunday, SSELY flow deepens from the surface to 750 mb further moistening the boundary layer as a stronger perturbation moves into the region. Again, isolated to widely scattered showers and isolated thunderstorms are indicated in the forecast. Max temps next weekend are forecast to be about 3 to 4 degrees above normal with highs in the upper 70s to lower 80s.
MARINE.
Light offshore flow late tonight and early Monday following weak frontal passage. Weak onshore flow develops Monday afternoon with Atlc sea breeze development. Southerly flow increases to 15-20 knots on Tuesday ahead of next cold front, then potential Small Craft Advisory headlines Tuesday night with the frontal passage as offshore flow develops at 15-25 knots that continues into Wed. Flow slowly becomes northerly on Thursday as high pressure builds north of the waters at 10-15 knots but seas remain elevated in the 3-7 ft range.
FIRE WEATHER.
Drier air behind the weak frontal passage tonight will lead to Min RH values as low as 20-25% across inland SE GA Monday but winds less than 10 mph will prevent the need for any Red Flag headlines. Dispersions will run high over parts of southeast GA rest of today, and, ahead a stronger cold front, area-wide for Tuesday. Dry and cooler air returns for Wed and Thu.
HYDROLOGY.
Rainfall amounts will be relatively low for the frontal passage on Tuesday/Tuesday night. Current forecast reflects amounts of around 0.25 to 0.65 inches for portions of southeast GA, with the higher amounts centered from near Alma to Baxley. Into northeast FL, a north to south precip gradient is shown, of just under 0.25 inches around I-10 corridor, and lower amounts going south to Ocala to Bunnell under 0.10 inches.
