Area Forecast Discussion National Weather Service Jacksonville FL 745 AM EDT Sat Oct 31 2020

AVIATION. [Through 12Z Sunday]

Light north-northeast winds less than 10 kt early this morning will increase and become predominantly northeast 8 to 12 kt with a few gusts to near 20 kt possible today as sfc high pressure remains north of the area. Mainly VFR at TAF sites at this time, but expect sky cover/cigs to deteriorate for most of the TAFs except for GNV and SGJ where VFR cigs should prevail through the late evening. For rest of the TAFs, MVFR cigs and a chance of showers are expected beginning in a few hours and have included some TEMPO groups for MVFR vsby in showers. A chance of showers continues into tonight and may diminish overnight as a cold front begins to approach the area from the northwest. A chance of some MVFR vsby late tonight for VQQ and GNV though confidence at fairly low at this time.

PREV DISCUSSION [406 AM EDT].

NEAR TERM [Through Tonight].

A strong ridge of high pressure will build over the northeast today. This will result in breezy conditions along our coastline with east- northeast winds around 10-15 mph and gusts to around 20 mph. Onshore flow will return some moisture to the coastal areas and PWAT values will recover to around 1-1.25" east of a line from St. Augustine, FL to Waycross, GA to Baxley, GA. Scattered showers will be possible today in this area. Temperatures today will be near climo normals, peaking in the low 70s in SE GA, mid 70s to low 80s in NE FL. Overnight lows will be in the upper 50s in SE GA, low 60s in NE FL.

SHORT TERM [Sunday Through Monday].

An upper level trough of low pressure will build over the eastern CONUS Sunday bringing a weak dry cold front through the area Sunday afternoon. Moisture is quite sparse with the frontal passage, so while a few showers can not be ruled out, particularly north of I- 10, and along the immediate the code. The daytime temperatures will still be on the warm side, peaking in the mid to upper 70s across interior SE GA to low/mid 80s. Overnight however, a MUCH colder airmass will advect into the area. Lows Sunday night will be in the mid to upper 40s in SE GA / Suwannee Valley, low to mid 50s across the rest of NE FL. Deep layer ridging will build over Southern Plains Monday, with the surface high centered over the ArkLaMiss region Monday night with dry conditions forecast. Northwest flow Monday, and veering northerly Monday night. Afternoon high temperatures will be coolest on Monday, peaking in the low-mid 60s in SE GA, mid to upper 60s in NE FL, and near 70 across north central FL. Lows Monday night will be in the upper 30s across SE GA to mid 40s coastal Georgia, over northeast FL mostly in the 40s, with NE FL beaches in lower 50s.

LONG TERM [Tuesday Through Saturday].

Temperatures will moderate Tuesday onward as heights rise as winds turn northeasterly. High pressure will be over the region Tuesday and Wednesday with dry conditions. The surface high will move northeast of the region over the Mid Atlantic Thursday and Friday. Moisture will return from the south, with the onshore flow leading to isolated coastal showers on Thursday. More pronounced priming of the boundary layer on Friday as flow becomes more easterly with precipitable water values increasing 1.4 to 1.6 along the coast in concert with a upper level short wave trough moving toward the region. This led to to a forecast with a higher coverage of showers for SE GA and NE FL Friday. Temperatures will trend a little below normal Tuesday night into Wednesday, then near to above Wednesday night through Friday.

MARINE.

A ridge of high pressure will build to our north today, allowing for the development of east winds around 20 knots and offshore seas building to 5 to 8 feet. Onshore winds today could also lead to the development of scattered showers today. Winds nearshore should subside to 15 to 20 knots this afternoon, but offshore winds and seas will remain elevated through tomorrow morning. A brief round of westerly winds Sunday morning will precede a dry cold front passage tomorrow afternoon. After that, moderate north-northeasterly winds will prevail through mid- week.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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.
