This last week of November was truly one for the books. After setting record high temperatures on Monday and Tuesday we managed to have a record setting snowfall at the Portland Jetport on Wednesday. The 7.4 inches was just enough to erase the old record of 7.0 inches set back in 1885. The wet heavy snow left thousands without power for Thanksgiving day leaving many uncooked turkeys in the refrigerator. We have a shot at one more record Saturday. The coldest high temperature for November 29th is 28 degrees set in 1945 and with the cold air mass currently in place we could come close to that. I expect temperatures to top out in the mid to upper 20s Saturday with morning sunshine followed by increasing afternoon cloudiness.
Warmer air is expected to head our way for Sunday and as it moves in aloft Saturday night some mixed precipitation should break out after midnight. This won't amount to much but could make for some slippery roads early Sunday morning. The warmer air will then arrive at the surface during the day Sunday sending temperatures close to 40 with warmer readings near the coast. This warm intrusion will be short lived because a cold front is going to move through our region on Monday. Temperatures should hit their peak early in the day then fall in the afternoon. By Tuesday we'll be back in the deep freeze. Warmer air will then try to return for Wednesday. Once again the transition could lead to some mixed precipitation for morning commuters.
