The noise could be a bad weld in the exhaust system "blowing". When you drove away, the crack closed up so you couldn't hear it. But it could be something else. Get the exhaust system inspected.

I hope you topped up the low oil before driving to work.

Have you checked the coolant level in the header tank? If it's ok, try a new thermostat.
