.WHAT HAS CHANGED... Precipitation has come to an end, with low clouds and mist lingering. While the threat for dense fog still exists, the persistent northerly winds will likely prevent widespread fog from developing this morning.

.KEY MESSAGES... - 1) Locally dense fog possible this morning.

- 2) Two frontal boundaries may bring additional showers and variable temperatures later this week.

KEY MESSAGE 1...Locally dense fog possible this morning.

Rain is coming to an end early this morning as a surface low pressure continues to move offshore. In its wake widespread low clouds and mist are ongoing with a light north wind. A Dense Fog Advisory continues in western MD through sunrise. Recent observations indicate the winds are just strong enough to keep widespread dense fog from developing, instead there is very low stratus. As a result, the Dense Fog Advisory likely will not need to be expanded. Will continue to monitor any areas of locally dense fog, but that threat should quickly diminish as we get close to sunrise.

Expect clouds to stick around for most of, if not the entire day. The CAD wedge in place due to yesterday's rain is going to take a while to break and probably won't entirely erode north of I-66 and east of the Blue Ridge/Catoctins. The best chance for clearing will be in the central Shenandoah Valley to the central VA Piedmont and these areas could see temps reach the low 50s this afternoon. Temps only reach the 40s where clouds remain.

High pressure moves over the area tonight with a stalled frontal boundary nearby. Conditions appear favorable for another round of low clouds and/or fog overnight tonight.

KEY MESSAGE 2...Two frontal boundaries may bring additional showers and variable temperatures later this week.

It should be well into the 50s Tuesday and Wednesday as a warm front sets up well north of the area. A few showers are possible across northern areas Wednesday. Uncertainty in temperature forecast begins to increase Thu as a backdoor front pushes into the area. A developing warm front associated with a potent Great Lakes surface low will bring better chances of rain areawide Thu afternoon- Fri while a pair of surface lows ride along the stalled frontal zone. Fri continues to have the largest spread with respect to temperatures with over 20 deg spread with high temperatures ranging anywhere from 40 to 60 degrees. Trends from the past 10 runs from the ECMWF (European Centre for Medium-Range Weather Forecasts) have also shown substantial variability with temps as high as 70F several days ago now down to 42 on the most recent 12Z run. A notable cold front crosses the area at the end of the week or early next week bringing noticeably colder temperatures to start the last week of the month.

Marine
Departing low pressure has increased northerly winds across most of the waters. Gusts of 20-25 knots are expected through early this afternoon where Small Craft Advisories are in place. Winds quickly diminish this evening into tonight as high pressure moves overhead.

SCA (Small Craft Advisory) conditions are possible Tuesday night into Thu morning, particularly across the southern waters due to strengthening flow.

Tides / Coastal Flooding
Onshore winds return tonight into Tuesday which is expected to result in higher tide levels across the area. Many sensitive locations could reach Action Stage during high tide, with Annapolis possibly reaching minor flood stage during the Tuesday high tide cycles.
