A vigorous trough will then deepen over the Great Lakes Sun through Sun night. Sfc high pressure will slide farther out to sea Sun into Sun night, as a strong cold front approaches from the WNW. Stronger SSW winds well in advance of the front during Sun, will help high temps climb into the upper 70s to lower 80s under a mostly sunny sky.

LONG TERM /MONDAY THROUGH THURSDAY/
As of 355 AM EDT Friday...

Key Messages:

- A strong cold front moves through the area Monday.

- Primarily dry conditions continue into middle of next week.

A strong cold front will move through the area Mon, as models show the upper trough 500mb anomalies reach minus 2 to minus 3 st dev by Tue, with stronger anomalies possible mid week. This will push a strong cold front through the area Mon, which will likely be followed by the coolest airmass of the season. Mon highs will range from the mid to upper 60s in the NW counties, to the mid to upper 70s across the SE. Mon night's lows will range through the 40s into the lower 50s. Tue will be much cooler with highs in the upper 50s to lower 60s, with lows Tue night in the upper 30s to upper 40s. Tue will have the most cloud cover for the extended forecast, with a partly sunny to mostly cloudy sky. Wed through Thu, sfc high pressure will gradually build in from the WNW. Partly to mostly sunny Wed with highs in the upper 50s to lower 60s. Mostly clear to partly cloudy Wed night with lows mainly in the lower to mid 40s.
Mostly sunny Thu with highs ranging through the 60s.

MARINE
As of 340 AM EDT Friday...

Key Points:

- Small Craft Advisories run through later this morning on the bay and coastal waters. Winds gradually diminish this morning through tonight.

- More benign boating conditions to start off the weekend. However, another round of Small Craft Advisories are likely with the next cold frontal passage late in the weekend into the start of next week.

Latest surface analysis reveals strong ~1026mb high pressure centered over the eastern Great Lakes. The post-tropical remnants of Tropical Cyclone Milton was analyzed SSW of Bermuda early this morning, with the pressure gradient between these two features resulting in a surge of northerly winds, which is slowly weakening as of this writing. Latest Obs and buoy reports reveal NNE winds 15- 20 kt in the bay and over the Atlantic coastal waters, with slightly lower winds averaging 10-15 kt in the rivers. Seas averaged 4-5 ft, with waves 2-3 ft across the bay and 1-2 ft rivers and sound.

SCA remains in place through later this morning over the bay, but should be able to be lowered shortly with winds trending lower by mid-late morning, as the pressure gradient slackens. SCA will be lowered last for the southern coastal waters, where seas will linger around 5 ft through around midday before subsiding. Winds become W to SW this afternoon and tonight, diminishing to 10-15 kt as the gradient slackens further through tonight. Meanwhile, high pressure builds in west of the waters. Seas remain 10-15 kt Sat into Sun morning. The next cold front approaches the waters from the NW on Sunday, with winds increasing pre-frontal Sunday afternoon and evening out of the SSW. Small Craft conditions appear likely Sunday night into Monday for all but the upper rivers ahead of the frontal passage, which crosses into the area Monday morning. SSW winds increase to 15-20 kt late Sunday and Sunday night with gusts to ~25 kt (highest upper bay zones north of Windmill Pt) and seas around 4- 6 ft. The front pushes south of the area Monday evening, with winds briefly subsiding. However, another surge of northerly winds and potential SCA is possible midweek (Tue night through Wed night), as the parent (full latitude) trough crosses the area, with chilly high pressure building in for the late week period.

High rip currents across the southern beaches and moderate rip currents for the northern beaches remain in effect today, moderate Rip all beaches tomorrow.
