Small craft advisory will be in effect tonight for the nearshore waters as the winds increase behind the frontal passage. High pressure builds in from the northwest into Tuesday. Tuesday into Wednesday, the high pressure builds in over the mid-atlantic as a low pressure system develops over the bahamas. This will cause a surge of strong northeasterly winds and high waves to move into our coastal waters. Showers will be possible on Tuesday and Wednesday.

AVIATION. [Through 00Z Tuesday]

Multilayered clouds continue affecting northeast FL this evening as the cold front and associated moisture move through the north and central FL area. A few showers linger over northeast FL and should be southeast of GNV and SGJ TAF sites in the next 2-3 hours. Brief period of MVFR cigs expected for CRG, GNV, and SGJ through late evening then clearing out with mid and high clouds continuing through Monday though these too will be diminish. Some scattered stratocumulus may affect CRG and SGJ terminals Monday with mean low level winds due northerly. Sfc winds will be northwest 8 to 12 kt and gusty tonight, and turning northwest to north on Monday.

PREV DISCUSSION [456 PM EST].

NEAR TERM [Through Monday].

A cold front is currently over north Florida moving to the southeast. Showers come to an end from northwest to southeast tonight as the cold front exits the region. Strong high pressure located over the upper Plains begins to build into the region from the northwest filtering in colder, drier air. Temperatures drop tonight with portions of inland southeast Georgia and Suwannee Valley briefly reaching freezing temperatures near sunrise. Lows tonight will range from the low 30s to the low 40s. Mostly sunny skies prevail tomorrow though highs will only reach the upper 40s to upper 50s. Northerly winds tomorrow will be breezy along the coast.

SHORT TERM [Monday Night Through Wednesday].

Cold, strong high pressure moves from the Mississippi River Valley into the Mid-Atlantic through Wednesday funneling cold, dry air into the region. Temperatures remain well below average until mid- week. A Freeze Watch is in effect for Monday night into Tuesday morning as a light freeze is likely across southeast Georgia and portions of inland northeast Florida. Lows Tuesday will range from the upper 20s to upper 30s. Continued cold air advection will lead to a widespread light freeze Wednesday morning except along the immediate coast. A hard freeze will be possible Wednesday morning as well with portions of inland southeast Georgia and Suwannee Valley reaching 27 degrees or lower. With relatively stronger winds overnight, wind chills could drop to the upper teens and 20s. High temperatures begin to rebound on Wednesday as they reach into the 50s.

Tuesday into Wednesday, strong northeasterly flow develops over our coastal waters as high pressure builds over the mid-Atlantic and low pressure develops over the Bahamas. With onshore flow, a few coastal showers will be possible on Wednesday. Gusty winds also prevail along the coast.

LONG TERM [Thursday Through Saturday].

On Thursday, onshore flow and coastal showers continue with weak coastal troughing as high pressure moves further to our northeast. Rain chances increase ahead of the next cold front Friday into Saturday. There is some uncertainty in timing with the next frontal passage. Temperatures continue to warm ahead of the next cold front with highs reaching into the 70s on Friday.

MARINE.

Small Craft Advisory will continue for the offshore waters into Monday night as 7 foot seas and winds linger. Small Craft Advisory will be in effect tonight for the nearshore waters as the winds increase behind the frontal passage. High pressure builds in from the northwest into Tuesday. Tuesday into Wednesday, the high pressure builds in over the mid-Atlantic as a low pressure system develops over the Bahamas. This will cause a surge of strong northeasterly winds and high waves to move into our coastal waters. Showers will be possible on Tuesday and Wednesday.

Rip Currents: Moderate Risk of rip currents today for NE FL beaches with a low risk of rip currents for SE GA beaches.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
