Irma Update Harvey Rains Sunday Summery Labor Day

Satellite and radar loops this morning show the remnant circulation of Harvey is moving east across the Ohio Valley. So far high pressure to the north is holding in firm and that is keeping it dry and sunny from Northern New Jersey & NYC north and eastward into the Hudson Valley and Connecticut. Meanwhile in Central & South Jersey and Eastern Pennsylvania clouds are increasing. Eventually the high will give way and we will see clouds move into all areas during this afternoon and evening. So far the rain on the radar is confined to Southern New Jersey & Southeastern Pennsylvania but that too will being to migrate northward late today and overnight. Temperatures are in the 60s to near 70 today after record lows were set this morning at several locations including Newark NJ, LaGuardia & Poughkeepsie in NY.

REGIONAL RADAR

The rain on the radar at the moment at least looks rather unimpressive. The heavier downpours that are nosing northward from North Carolina could be part of the rains that get here later tonight and for at least part of Sunday.

The big question for Sunday is whether weather conditions improve during the afternoon from south to north and there is a fair chance of that happening in my view. Temperatures will be back into the 70s Sunday. Monday is going to be a very warm Labor Day with sunshine and highs in the 80s.

HURRICANE IRMA MIDDAY UPDATE

It appears that Irma is undergoing another round of strengthening and the motion is definitely south of west based on the satellite loop. The eye has come back. The storm actually looks less ragged and more symetrical again. The outflow is excellent as is the inflow and there is no sign of any important wind shear issues. The west southwest motion will set the stage for how big a threat is (if any) to the Northern Leeward Islands.
