Discussion

KEY MESSAGE 1...A couple more rounds of frost and freeze impacts are expected both tonight and Sunday night where the growing season continues.

Little change in the overall synoptic pattern is expected through tonight with strong surface high pressure essentially overhead. In fact, 500 mb temperatures are a touch cooler tonight but surface dewpoints are expected to be a couple of degrees higher tonight. Overall, this should result in low temperatures pretty similar to those observed earlier this morning with lows mainly in the low to mid 30s across the region, outside of the barrier islands and coastal Delaware.

Frost Advisories were upgraded to Freeze Warnings for portions of central and southern New Jersey. Dewpoints have trended a bit lower ahead of the sea breeze in this corridor where temperatures are more prone to falling below a consensus of guidance. Skies will be more pristinely clear tonight with calm winds, unlike the scattered to broken cirrus we had in place last night, so opted to nudge temperatures down another degree or two into the low 30s. This justifies the warning upgrade for the aforementioned areas. Elsewhere, Frost Advisories remain in place for tonight where the growing season remains active (along and SE of I-95). The exception is for the barrier islands of NJ and coastal DE, which should experience lows in the 40s again. Would not be surprised to see some areas dip into the upper 20s, more notably across the Pine Barrens of South Jersey and sheltered valleys of NW NJ and the southern Poconos.

Temperatures will then begin to moderate on Sunday before another round of frost is possible for Sunday night into Monday morning. Lows around the region will mainly be in the mid 30s to low 40s. Depending on how tonight's frost advisories pan out will determine where frost advisories may be warranted on Sunday night...more details to come in future updates.

KEY MESSAGE 2...Water levels are decreasing and remaining Coastal Flood Advisories have been cancelled. Spotty minor tidal flooding may linger through daytime Sunday.

Water levels are continuing to decrease in the back bay areas of Ocean County, NJ and Sussex County, Delaware and no further widespread tidal flooding is expected. As a result, the Coastal Flood Advisory for these counties has been cancelled. Spotty minor tidal flooding may linger in the back bays though over the next two high tide cycles, through daytime Sunday.
