Temperatures will be above normal for this time of year, with highs climbing into the low 80s along the coast, with mid 80s elsewhere. A cold front edges into the area tonight, northeasterly breeziness will develop along the oceanfront/riverfront areas. Elevated breeziness and a layer of stratocumulus will lead to slightly warmer lows early Monday morning and deter any considerable fog development. The highest chances for post frontal nocturnal status looks at this time north of I-10. Elevated breeziness and a layer of stratocumulus will lead to slightly warmer lows early Monday morning and deter any considerable fog development.
Onshore (E-NE) flow will increase slightly Mon as reinforcing high pressure builds south across the area with frequent gusts 17-20 KT at coastal terminals. Temperatures will be near to slightly above normal for this time of year, with highs climbing into the low 80s along the coast and south of the Orlando metro, with mid 80s forecast near and north of the I-4 corridor. The high risk across the Treasure Coast and southern Brevard has been expanded northward this morning to include northern Brevard and the Volusia County beaches.
(Tonight through Monday night) Mostly clear skies and warm temperatures prevail (again) today with the subtropical ridge to the west continuing to aid in our quiet weather. Mid-level ridging begins to break down as an upper level trough begins to move onshore over the west coast overnight.
Otherwise, highs in the Valley will be cooler than normal, generally in the 60s, while highs in at higher elevations will be in the mid 40s to low 60s.

This ridge however begins to shift east and flattens out as deep trough drops into the Pacific NW.
1241 PM CDT Sun Oct 27 2024 (Today through Monday) Key Messages: - Another Round of Dense Fog this Morning In the short term, things will continue remain quiet over the next couple of days with the influence of the ridge that is currently centered over Baja California. The influence of the ridge is also expected to yield areas of dense fog again this morning similar to yesterday.
A high pressure system over the area will gradually slide eastward tonight and Monday. As the high slides eastward on Monday, a southerly breeze will allow for afternoon temperatures to warm up slightly compared to Sunday. Very dry air at the top of the mixing level will allow for afternoon dewpoints to be on the lower side of guidance.
(Tonight) Lingering cloud cover is gradually beginning to move east of the area, as an upper wave traverses to the ESE and high pressure at the sfc becomes entrenched across the mid Atlantic states. With low level flow veering to the ESE coupled with clearing skies, lows into early Mon look to fall into the lower/mid 50s for most spots.

- Winter Storm Watches have been issued for the higher elevations of the Wind River and Bighorn Range.
Temperatures within the wedge will be noticeably cooler than the last few days, with highs being limited to the mid 60s to mid 70s (with the coolest temperatures in the far northeast). After the morning begins with lows mainly in the 50s, highs will be limited once again under the wedge, rising into the low 70s in north Georgia and mid to upper 70s in central Georgia.
(Now through Monday) A little change of pace will be on the way for part of the area tomorrow as a weak backdoor cold front slowly moves into the area. Upper troughing that has lingered across the area will move out allowing for subtle ridging to build in. A cold air damming event (shallow cooler air gets pushed up against the Appalachian mountains and funnels southward) will spill into the gulf coast states. This shallow cooler air will move in from the east tomorrow potentially bringing some cooler high temperatures across the far eastern counties. OTher than temperatures, we should remain dry given ridging building in and overall subsidence in place.

The low level jet will increase with 35 to 45 knot 850mb winds and increasing surface winds by daybreak. Winds will continue to increase through the afternoon hours tomorrow as heights fall ahead of the upper trough and surface pressure gradients tighten with a change of about 3mb/3hr.
With high pressure now centered pretty much directly overhead, nearly calm winds are settling overhead as high clouds continue to stream in across the FL peninsula. Zonal flow remains in place aloft over the region through the next couple of days before ridging builds in over the southeast. At the surface, high pressure keeps a northeasterly flow in place and this flow increases a bit through the week as the pressure gradient tightens.
The high should broaden its influence more southward in the late night, which should cause winds to pick up some. Mild conditions are otherwise expected for the overnight with lows by daybreak Monday cooling into the low/mid 50s.
Ridging will remain aloft while high pressure will remain in the mid Atlantic States. This is due to the high pressure to our north interacting with a cold front that will be pushing through the midwest and heading east.
406 AM EDT Mon Oct 28 2024 Cool high pressure will prevail today with some showers tonight and Tuesday due to a coastal trough.
Low pressure from the Pacific will bring increased winds, much cooler temperatures, and chances for rain and mountain snow today and Tuesday.
