Statement as of 7:00 am EST on March 7, 2007
... Record low temperature set in Portland today...
The temperature at the Portland International Jetport dropped to 6
degrees below zero as of 7 am today. This broke the old record low
of minus 3 for March 7th which was set back in 1989.
On Tuesday, March 6th, the temperature at the Portland International
Jetport only reached 18 degrees. This was the coldest high
temperature recorded for March 6th since records began. The previous
record cold high was 26 degrees set in 1972 and 1999.
The low temperature on Tuesday was zero degrees, not a record.
However this low and the high of 18 gave Portland an average
temperature of 9 degrees for the day, which set a record for the
coldest average temperature for March 6th. The old record was 10
degrees set in 1948.
Additional records for low temperatures, cold high temperatures and
cold daily averages may be broken at Portland as cold Arctic air
remains over the region today and Thursday.
Temperature records at the jetport began on November 25th, 1940.
Why Portland? There is no NWS office in New Hampshire. Cheshire and Hillsborough Counties get their forecasts from the Boston NWS office, and the rest of New Hampshire gets their forecasts from the NWS office in Gray, ME. (And never mind that the Manchester airport happens to straddle the boundary between Hillsborough and Rockingham Counties.)
