Area Forecast Discussion National Weather Service Jacksonville FL 811 AM EDT Tue Sep 28 2021

UPDATE.

A weakening ridge of high pressure will be over region Today. East coast sea breeze should make it past I95, with Gulf sea breeze moving into Suwannee and Gilchrist counties this afternoon. Enough convergence and moisture possible far western forecast area for a few showers to develop on the Gulf sea breeze.

Highs in the middle 80s will be common this afternoon.

AVIATION. [Through 12Z Wednesday]

Fog may restrict visibilities overnight inland, otherwise prevailing VFR conditions anticipated.

PREV DISCUSSION [258 AM EDT].

NEAR TERM [Through Tonight].

High pressure will settle southward just to our east over the local coastal waters today. Fair weather continues with subsidence and a dry airmass (PWATs < 1 inch) overhead. Light and variable winds around 5 mph prevail across inland areas while winds become east-southeasterly at the coast around 5-10 mph. High temperatures will be above seasonal average in the mid to upper 80s. Radiational cooling will keep overnight lows below average in the low to mid 60s inland and upper 60s along the coast.

SHORT TERM [Wednesday Through Thursday].

An amplified weather pattern will prevail aloft, as deep troughing digs from southeastern Canada across New England and the Mid-Atlantic states, while ridging gradually expands from the entire length of the Mississippi Valley eastward towards the Ohio and Tennessee Valleys as well as the southeastern states by Thursday night. A weak surface pressure pattern will prevail locally on Wednesday as ridging weakens overhead. Meanwhile, strong high pressure building southward from Hudson Bay, Canada will push a cold front down the U.S. eastern seaboard on Wednesday and Wednesday night, with this boundary approaching the southeast GA by Thursday evening and then reaching the FL/GA border by sunrise on Friday. This pattern will yield a dry and subsident prevailing northerly flow for our area on Wednesday, followed by low level winds shifting to easterly on Thursday as surface pressures rise to our north as high pressure expands southward from the eastern Great Lakes.

The dry and subsident weather pattern will persist locally during the short term period, with plenty of sunshine boosting highs to around 90 at most inland locations, while the afternoon sea breeze keeps coastal highs in the mid 80s. Fair skies and decoupling winds will result in lows falling to the low and middle 60s inland both Wednesday and Thursday nights. A land breeze developing on Wednesday night should drop coastal lows to the mid to upper 60s, while a light onshore breeze on Thursday night keeps coastal lows in the upper 60s to around 70.

LONG TERM [Friday Through Monday].

The weather pattern aloft will gradually de-amplify during the upcoming weekend, as ridging aloft centered over our region begins to flatten due to troughing progressing eastward from the Desert Southwest across the Plains States. The backdoor cold front will push across northeast and north central FL on Friday morning, and our local pressure gradient will tighten from north to south as strong surface ridging wedges down the southeastern seaboard. Despite strengthening onshore winds, deep moisture will remain absent of our area, and only a few showers are expected to develop over the northeast FL coastal waters in the convergent low level flow. Isolated showers may occasionally move onshore from around St. Augustine southward through the southern St. Johns River basin through the period, with dry weather continuing elsewhere. Breezy onshore winds are expected during the daytime hours for locations along and east of Interstate 95.

Slightly above average highs on Friday will cool back to early October climatology during the weekend as heights aloft gradually fall. An onshore breeze will keep lows on Friday night in the lower 70s at coastal locations, with decoupling winds keeping inland lows in the mid to upper 60s. Lows will cool off a few degrees during the weekend as subsidence strengthens and radiational cooling sets up at inland locations.

MARINE.

Weakening high pressure will settle over the coastal waters today and shift southward on Wednesday. A weak cold front is forecast to move southward across our local waters by Thursday night as high pressure builds in from the north. East to northeast winds will strengthen in the wake of this front from Friday through the weekend. Meanwhile, long period swells from Distant Major Hurricane Sam will enter our local waters beginning Wednesday night, with seas possibly reaching caution levels Friday night and Saturday.

Rip Currents: Moderate risk of rip currents for all area beaches. Surf will increase late week as long period ocean swells from distant Major Hurricane Sam arrive at area beaches on Wednesday night.
