UPDATE... High pressure in control today, providing a E/NE flow across the region. Another dry day is in store and is supported by MFL's 23/12Z sounding with a PW of 1.21 inches, which is below the 10th percentile for this time of year. With winds and seas calming down, the Small Craft Advisory is set to expire, though small craft operators should continue to exercise caution, especially around jetties and inlets. Otherwise, high temperatures today are forecast to stay a tad below average in the mid to upper 80s, with near 90 along the west coast.

Today through Thursday... The center of an expansive mid-upper anticyclone will migrate from the Gulf Coast States into the eastern Gulf of Mexico, as an upper low progresses towards the eastern Bahamas. Surface high pressure will prevail from the Ohio Valley equatorward into the Gulf of Mexico and Florida, with a moisture gradient gradually sinking south from the Florida Straits into the northern Caribbean Sea. With deep layer ridging prevailing across the region look for dry and subsident conditions with only a small chance for a shower late in the period. In fact, precipitable water values as low as 1 inch are possible late Monday into Wednesday, which is around 2 standard deviations below the climatological mean per NAEFS standardized anomalies. This is also nearing record daily minimum values per the Storm Prediction Center Sounding Climatology archive. This will be our first taste of fall-like weather, as overnight lows cool off a bit given the dry air mass. Inland areas, particularly those near the Lake, are likely to drop of into the upper 60s to around 70 for lows during the early part of the week, with a slight warming trend thereafter. Highs will be seasonal across South Florida with temperatures generally ranging between 85 and 90 degrees, and perhaps a few degrees warmer at times over western interior areas. Winds will gradually decrease in strength today and become even lighter through mid-week as the pressure gradient relaxes with high pressure in control.

Friday through Sunday
Ridging aloft will weaken as the mid to upper low pressure area advances from the western Bahamas through South Florida. Meanwhile surface high pressure will strengthen across the western Atlantic and Atlantic coastal states. This will bring renewed breeziness and shower chances to South Florida as moisture increases across the area. Unsettled conditions are likely to continue beyond the weekend as the flow turns southeasterly advecting deep moisture into the area.

Marine Discussion
Fresh ENE breezes early this morning will subside to moderate this afternoon as higher seas across the Atlantic waters gradually subside. Small Craft Operators should continue to exercise caution, as occasional bouts of higher winds and seas remain possible today. Generally quiet boating conditions are then expected for Tuesday into Thursday, with increased breeziness and shower chances returning for late week into the weekend.

Beach Forecast
A high rip current risk continues for all Atlantic beaches through this evening, with an elevated risk likely persisting for at least the next few days. Quiet weather is anticipated through mid week.
