Chillier outlook

When the moon is shining more brightly than the sun at 6:30 a.m. as it was this morning, it must be October.

September's average temperature went into the books at 1.2 degrees above the 30-degree normal in Philadelphia.

While that's not proof of global warming, it did mark the 21st consecutive month in which the official temperature failed to come in below normal.

October is off to a mild start, but the longer-term outlooks suggest that the 21-month streak might be in jeopardy.

The Climate Prediction Center two-week outlook has a blue cast over much of the nation as the pattern over North America is one that that would warm the heart of snow-lovers, if this were a few months on.

The models are showing a strong area of high pressure in the far northwest that should drive chilly air deep into the contiguous 48 states.

Dave Tolleris, meteorologist at, mentioned that pattern on Friday in issuing his two-week forecast.

The climate center also sees the odds favoring above-normal precipitation.

September finished with an official 5.48 inches of rain in Philadelphia, one of the rainier Septembers in the period of record.

That also was quite close to the August total as the region continues to rebound from the dryness that characterized the first half of the year.
