Not necessarily any connection. A few days of extreme heat or cold are not indicators one way or another because global warming is a slow overall trend that involves averages and massive changes. For some reason people find that hard to understand. But the polar ice caps are still melting at an unprecedented rate, so three or four days of extreme cold in some places don't mean much.

Currently -18F/-28C here, just before dawn. But tomorrow we're supposed to be back to near normal temperatures for this time of year, at +20F.
