Centre County Lows 3/13

Pretty darn chilly for March 13th! The wind chill reached -10 @ AccuWeather HQ's Davis Vantage Pro weather station this morning. Low temperatures were in the single digits, but owing to the winds, were fairly consistent. PSU did not set a record; it was +3 in 1984.

Selected* Online Centre County Lows this morning:

Elliot Abrams: +7
Jesse Ferrell: +8
Corl Street:   +8
Marshall Moss: +8
AccuWeather:   +8
PSU Shelter:   +9
Walker Top:    +9
KUNV Airport: +10

If your station is not included in this list, please post a comment with your low from this morning.

Because of the single-digit reading at Penn State, I have adjusted the Winter Summary blog to read 29 days at or below 10 degrees, vs. 4 last winter.

The temperature fall last night was quite something -- the Davis Vantage Pro weather station at my house fell as much as 12 degrees per hour, and 33 degrees overnight... and the high yesterday was 62!

Lowest Pressure Since Sandy

State College (UNV airport) bottomed out at 29.07" Hg sea-level pressure tonight as a major storm system passed over us. As far as I can tell, this was the lowest pressure we've seen since Hurricane Sandy dropped us to 28.72" on October 31, 2012.

PSU Winter Vs. 2012-2013

Winter 2013-2014 compared to 2012-2013:
# of mornings @ PSU <10  F: 29* this yr so far; 4 last winter.
# of mornings @ PSU <=0  F:  9 this yr so far; 0 last winter.

Days Above Normal @ PSU Dec-Feb 2012-2013: 54%
Days Above Normal @ PSU Dec-Feb 2013-2014: 30%

Lowest Temp This Winter: -9, Coldest Since 1994's -18
The data above is from AccuWeather's KPSU database. *Updated 3/13 to add one more day.

Also from the AccuWeather data: Due to the unusually cold winter this season versus last, Penn State recorded 63 days (70%) with at least a trace of snow, and 61 days (68%) with at least an inch of snow cover this winter (90 days Dec-Feb). Last winter those numbers were 48 (53%) and 32 (36%). In other words: The number of days with snow cover was nearly twice this season versus last!

The official PSU temperature stats for last winter & this winter are shown below; we were a full 6.19 degrees colder this winter than last!

In addition to the temperature record mentioned above, 1994 was quite a winter. Harrisburg had at least 1" of snow on the ground for 71 consecutive days, which established a new record (this year they only had 45 non-consecutive). 1994's streak continued until they had 75 consecutive days, ending on March 20th. At Penn State, however, 1994's snow cover lasted from January 3 to March 31 (88 consecutive days!) And of course, that snow year (July 1993 - June 1994) set the record of 109.3" here in State College (as well as the Annual Snowfall at 102.6").

Corl Street Station Returns

After going offline in November 2013, the Corl Street Weather Station (a Davis Vantage Vue station on the school's roof) has started transmitting online once again, as of today (March 7th).

It turned out that the internal "C" batteries had leaked battery acid (again!) and once the console was cleaned and rebooted, it started uploading to the Internet once again.

Some GOOD news: The console continued to record all winter, so we now know that the station fell to +4 on March 4th, and had a yearly low of -10 during the January cold outbreak, probably on the 7th.
