A cool 42° here at the Center at 7am. Hours of daylight are retreating as are the warm temperatures, BUT we do have above normal temps in the forecast as the battle of warm and cool air continues. I am seeing mid 70s in the long range models into October.
On September 17, Arctic sea ice extent stood at 4.60 million square kilometers (1.78 million square miles). This was 1.69 million square kilometers (653,000 square miles) below the 1981 to 2010 long-term average extent for this day of year, but 1.21 million square kilometers (467,000 square miles) above the record low for this day of year set in 2012.
With the onset of autumn, air temperatures are dropping across the Arctic. The seasonal minimum extent is imminent. The Arctic’s minimum sea ice extent is likely to be the 6th lowest in the 39-year satellite record.
Cool conditions in July played a large role in slowing the rate of summer ice loss. The Northern Sea Route nevertheless appears to be navigable. The Northwest Passage, including both the Northern and Southern routes, will not open this year.
Snow is building across the northern territories of Canada, Alaska and Siberia. There are winter weather advisories for the Rockies (above 6000 feet) in Montana. To put this in perspective the highest point in the Appalachians is Mount Mitchell in North Carolina at 6684 feet. The highest peak in the Rockies is Mount Elbert at 14440 feet in Colorado.
Mount Washington, called Agiocochook by some Native American tribes, is the highest peak in the Northeastern United States at 6,288.2 ft (1,916.6 m) and the most topographically prominent mountain east of the Mississippi River.
The mountain is notorious for its erratic weather. On the afternoon of April 12, 1934, the Mount Washington Observatory recorded a windspeed of 231 miles per hour (372 km/h) at the summit, the world record for most of the 20th century, and still a record for measured wind speeds not involved with a tropical cyclone. I went there a couple times when I lived in Maine and visited a lot of the Appalachians in New England and Quebec.
We have chances of above normal temps and rain through the next two weeks – normal temps are in the mid sixties. Sunrise and sunset times are almost equal at around 7:30.
We could see some light rain moving into the area tonight into Friday as we move into a wet unsettled pattern. With a warm front in the area next week we may even see temps flirting with 80° again. Steady rain is possible Sunday night into Monday.
