Cold eases next week

The upper air pattern will gradually change to a milder flow pattern next week. Highs should recover into the teens above zero next week. There are signs that much milder Pacific air may return in the last days of February. NOAA’s GFS 16-day outlook prints out temperatures back into the 30s, and even one day in the 40s in late February.

46 in late February? We’ll probably see people in shorts after this weekend’s cold outbreak.
