Week 5 and 6 are downright voodoo. I looked at H5 through week 4. Week 3 had a -EPO, weak East -NAO and a weak SE ridge. Week 4 has a massive cold pocket in Canada. However, we all know how bad even week 3 and 4 can be.
I mean 50mph winds against foliated trees will take them down for sure. In addition to what Tip said, we seemed to have a downslope event in these areas. The lower elevations on the west side of ORH hiils into the CT valley all had some decent damage. Unlike winter events that have strong LLJs as well, we didn't have a cold airmass to work with. The cold air allows for the stable wedge to form and therefore prevents mixing.
