Wx map shows 1032mb surface high over the northeastern U.S. with ridging southward to the Louisiana & Texas coastal waters where the stationary front is located. South of the front, warmer temperatures & dewpoints with patchy fog. North of the front, northeast winds and slightly cooler temperatures. Most of the precipitation has ended, but kept a slight chance across the eastern coastal waters near the front for this morning and afternoon. Otherwise, mostly cloudy and temperatures in the upper 50s to mid 60s expected for afternoon highs.

Biggest issue this morning is the patchy fog that has developed across the region. While visibilities have remained above dense fog criteria, the very low stratus deck enshrouding the region will likely result in slow fog dissipation this morning. Offshore, the marine fog advisory will be allowed to expire at 6 AM, but high res visibility guidance is in good agreement on the fog building back in across the nearshore waters after sunset tonight so felt comfortable issuing another marine fog advisory this evening through Sunday morning.

A weak surface front currently extends over the outer coastal waters this morning where it is expected to meander through most of the day before lifting north as a warm front this evening into Sunday. Scattered showers are expected to develop in the vicinity of the boundary and lift inland along with the boundary.

An upper level low and it's corresponding surface low will eject northeast out of the four corners region Sunday pushing a weak cold front through the area Monday. With plenty of moisture to tap into, widespread showers and isolated thunderstorms are expected, but with no instability to speak of there is little threat of the storms becoming particularly strong. This boundary won't make it very far off the coast before stalling which could keep some precipitation in the outer coastal waters Tuesday. The boundary lifts north once again late Tuesday pulling some of these showers back into the region Tuesday night ahead of the next frontal boundary that will swing through the area Wednesday. This one looks to have a bit more kick to it and will not only sweep the persistent moisture out of the region, but also advect in some materially cooler air that will drop temperatures closer to seasonal normals.

The progressive pattern continues late into the week with another frontal boundary expected to approach the region next weekend.
