Weird weather

This is the temp changes here this week. On Monday, we were wearing
winter jackets, gloves and hats...temp was around -15 C in the morning
and got up to 0 - +4 or so. It stayed like that until Thursday when
it only dropped to around -5 and the temp raised to +9. Friday was
really nice - temps got up to +13. Then yesterday it was BEAUTIFUL.
When I was coming home from the city, the thermostat in my car read
+23!!! We were outside in t-shirts. Saw people in shorts in the
city.

It is supposed to be almost that nice today again...but tomorrow
(Monday) we are only supposed to get up to +7. How is that for swift
changes in temps.
