From Meteorologist Steve Glazier,
Well Burlington did it again. The Queen City averaged +1.3° compared to average for the month of September 2012. However three of eight cities had above average temperatures in September. Here's the recap:
|CITY||OBSERVED HIGH||OBSERVED LOW||AVG TEMP||DEPARTURE||PRECIP||DEPARTURE|
For Burlington this continues the warmer than average streak. The current (and ongoing) record stands at 18 consecutive months of above average temperatures. This streak started in April of 2011. Since then, the temperature has been +3.6° to average. The smallest departure from average in that time was April and June 2011 at +0.6° to average. The largest departure was March 2012 with +12.2° to average.
In September, the number of cities below average outnumbered the cities above average, in terms of temperature. Thus the warm weather was not true for everyone, especially the observation from the Northeast Kingdom. St. Johnsbury was the coolest at -2.9° to average. I tallied this information from the NWS climate page here: http://www.nws.noaa.gov/climate/xmacis.php?wfo=btv
September 2012 began warm and dry. The first few days featured high temperatures in the lower 80s in the Champlain Valley, with no rain. A big rain storm came in on September 4 and 5 where Burlington received 3.06" in a 24 hour period. That storm put all the towns above average for the month, with the average departure for rainfall ranging from +1 to +2 inches. Notice Morrisville, VT recorded below average precip. Use caution when looking at that data point, as there are questions of validity with that reporting station's precip observation.
The outlook for the next three months from the Climate Prediction Center is for warmer than average weather in the Northeast. http://www.cpc.ncep.noaa.gov/ Climate forecasters are watching the presence and strengthening of El Nino, which could end our warmer than average weather this winter. http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/
