Synopsis
High pressure will continue through much of the rest of the week before a low pressure system tracks through the Carolinas on Friday and then well offshore to the northeast by Sunday. High pressure returns behind that system to start next week.

.NEAR TERM Through Tonight
Clouds are beginning to erode from north to south this morning and will continue to do so through the remainder of today. Overall a nice day is expected once clouds begin to clear out. Breezy conditions with northwest winds 10-15 mph occasional gusts around 20-25 mph will slowly diminish through the day and turn more north to northwest. Highs will warm a few degrees above normal but should not get out of the 40s anywhere, and 30s for higher elevations.

.SHORT TERM /THURSDAY THROUGH 6am THURSDAY/... High pressure will continue to move east across Ontario and into Quebec tonight. A dry and seasonably cool NE flow around the high will maintain fair weather tonight. Since there will be fewer clouds than recent nights, the lows will be colder. Across the southern Poconos and north NJ this means lows in the teens while other areas will see readings drop into the low/mid 20s. Winds will be light.

Long Term - Thursday Through Tuesday
Quiet sensible weather continues through the day Thursday as broad dome of high pressure pushes southeast out of Canada into New England. This sets up generally northerly flow across the region but the winds will mainly be light and at times variable under mostly cloudy skies. The pattern starts to change Friday night as a developing low pressure system starts to deepen as it tracks from the Gulf Coast through the Carolinas. Trends in the guidance and ensemble means continue to point to the system becoming a fish storm rather than one that would impact the region. Portions of DelMarVa and southern New Jersey could see a glancing blow of precipitation but thermal profiles suggest that it would be a rain event as the GFS soundings across DelMarVa show a melting layer greater than 1000 feet.

Offshore winds will start to ramp up as the system pulls away on Sunday as the pressure gradient between the departing low and incoming high pressure system increase. Sensible weather conditions should be dry on Sunday with little in the way of precipitation expected under mostly cloudy skies and temps in the 40s.

High pressure makes a brief return before another progressive low pressure system tracks through the southern plains into the Mid Atlantic bringing rain showers.

Temps throughout the extended will be normal to above normal with highs in the 40s through the weekend warming to the 50s to start next week. Low's follow the same trajectory with temps staying above normal warming into the low 40s by early next week.

Marine
Breezy conditions will continue across the waters today tonight as the pressure gradient remains fairly tight across the area. Northwest to north winds will continue with gusts of 20 knots expected, with an occasional gusty around 25 knots early. 25 knot gusts are not expected to be frequent so we have not issued a Small Craft Advisory.

Outlook... Wednesday thru Fri...Below SCA (Small Craft Advisory) conditions expected.

Friday night through Sunday...Winds/seas may start to increase by the Saturday night and Sunday time frame, potentially resulting in SCA (Small Craft Advisory) conditions by this time but the exact timing is to be determined
