925pm EDT Sunday May 22 2022

A strong cold front was moving through our region this evening, and it will settle offshore on Monday. High pressure builds in for Tuesday and Wednesday, then a frontal system may approach the area later next week.

Near Term - Through Monday
A cold front was moving southeastward across the Interstate 95 Corridor in our region around 9:00 PM. The boundary will pass off the coast and move out to sea overnight.

The showers and thunderstorms with and ahead of the cold front will continue to weaken slowly. As a result, we were able to allow the Severe Thunderstorm Watch to expire. The last of the precipitation is forecast to settle in eastern Maryland and Delaware and it is expected to dissipate in that area as the front begins to move farther offshore.

The sky is anticipated to remain mostly cloudy for much of the night with a northwest to north wind 5 to 10 MPH. Low temperatures are expected to range from around 50 in the Poconos to the middle 60s in southern Delaware.

Monday looks cloudy, but showers should stay to the south and west of the region. Will keep the forecast dry. Highs on Monday will top off in the mid and upper 70s.

Short Term - Monday Night Through Tuesday Night
The boundary will be well south of the area in the short term as surface high pressure drifts eastward across southern Ontario and Quebec provinces. Northeasterly low level flow combined with ample moisture in mid and upper levels will result in mainly overcast conditions and temperatures moderated by the marine influence. Low level moisture will be more plentiful in the Delmarva where isolated showers are possible.

Long Term - Wednesday Through Sunday
The long term forecast remains on track per the latest model guidance.

A persistent onshore flow will allow dewpoints to moderate into the 50s Wednesday while also keeping high temperatures only in the low 70s. Mostly cloudy to overcast skies will persist with most of the region remaining dry.

Thursday into Friday an upper level low that formed over the western United States will eject northeast towards the Great Lakes region. Surface low pressure will deepen as it heads towards Lake Superior with multiple pieces of PV advecting over the CWA. As this occurs, the chances of precipitation will increase through the day Thursday.

On Friday, a surface cold front will sweep through the region as the upper level low starts to fill. This means precipitation will exit the coast Friday night with clearing expected Saturday morning as the dry conveyor belt moves overhead. Behind the cold front, ridging and associated subsidence will make for a rain-free Saturday and Sunday.

Sub-Small Craft Advisory conditions. Winds shift to the NW overnight behind a cold front.

Sub-SCA (Small Craft Advisory) conditions expected Monday with NE winds around 10 kt.

Outlook... Monday night-Wednesday...No marine headlines anticipated. Onshore winds Monday night into Tuesday and through midweek. Seas of 2 to 4 ft expected.

Thursday And Friday
Winds and waves below small craft advisory levels with scattered showers and thunderstorms. Seas 3 to 4 ft.

Rip Currents... An onshore wind around 10 MPH is expected for Monday with breaking waves of 1 to 2 feet. We are anticipating a LOW risk for the development of dangerous rip currents at that time.

A northeast wind is forecast to increase to 10 to 15 MPH on Tuesday with breaking waves of 2 to 3 feet. The persistent onshore flow is expected to lead to a MODERATE risk of dangerous rip currents on Tuesday.
