Omg it's so crazy that Manhattan is below 50 even with the urban heat island! Imagine if we got this pattern in the late 70s, it wouldve been freezing!
The UHI doesn't have much effect on a cloudy, rainy day. The biggest effect is felt on clear, dry and windless nights. It affects night time temperatures much more than daytime temps.

Makes sense. Probavly that's why you can walk around NYC in a tank top at night during the summer
Aaand Seattle is 14 degrees warmer than San diego. How?
This partly explains why.. The other part is Clouds over San D, sunny over Seattle.
850mb temps (Temps at 5000 feet)
1. See why Minnesota is breaking record highs or near? (warm mid level push north which the air mass has moved East. Remember Alberta had those warm mid level temps?)
2. See why snow fell in TN and NC mountains?
3. See why Southeast is cooler than Upper Mid West?(both areas sunny)
4. See why Coastal CA is cooler than PacNW?
Lets go further up for curiosity..
Darker blues = below freezing and it's no coincidence that's where the Upper Lows are.
