For an anniversary gift I ordered and received the following framed map from my wife.
It is an aviation map of western Pennsylvania with a multicolor LED placed at each airport location that issues METARs (METeorological Terminal Aviation routine weather Report). The color of each LED indicates the ceiling and visibility.
VFR (>3000ft ceilings and >5nm visibility) = Green
MFR (1000-3000ft ceilings and 3-5nm visibility) = Blue
IFR (500-1000ft ceilings and 1-3nm visibility) = Red
LIFR (<500ft ceilings or <1nm visibility) = Purple
Smoke = Gray
METAR older than 6 hours = Blank
METAR data are processed by a Raspberry Pi, a low-cost single-board computer, which is fastened behind the map. Data are received via a WiFi connection every five minutes. The brightness of the LEDs also changes for day/night conditions.
Today is the 45th anniversary of the wreck of The Edmund Fitzgerald. A colleague of mine, and former roommate at SUNY-Oswego, asked if the storm that sank the ship, also affected Oswego, NY, on that fateful day (November 10, 1975). One of the advantages of being retired is having the time to do such research.
The high of 69 F and low of 52 F, quite warm for that time of year, confirms that Oswego, was in the warm sector of the storm system as a warm front passed through the area. The surface and 850 mb analysis shows the winds in Oswego were from the south and not off Lake Ontario. Exact wind speeds can not be ascertained from the charts, but judging from the tight isobars and geopotential isopleths, it was probably brisk and accounts for the warm air advection. Also, 1.15 inches of rain fell during the day. A cold front moved through later that evening.
So The Edmund Fitzgerald Storm did affect SUNY-Oswego on Monday, November 10, 1975.
October was 1.0 deg F above normal for temperature. The high for the month was 80.6 deg. F recorded on October 22. The low for the month was 27.7 deg F, recorded on Oct 17.

Meteorological Summer is officially over. Here is a brief summary of June 1-August 31 in Stormstown, PA:
Number of days Max T >= 90 F: 18
Max T: 95.1 – July 18, 2020
Min T: 40.9 – June 1, 2020
Jun Dep from Normal: 0.1
Jul Dep from Normal: 3.8
Aug Dep from Normal: 2.2
Heating Degree Days: 108 Cooling Degree Days: 761
The main feature of the summer was the moderate drought conditions that developed during July and August. All of Centre County experienced those conditions. Between June 10, 2020, when it rained 0.91″ and August 28, 2020, when it rained 0.75″, there wasn’t a single day when rainfall exceeded 0.50″. In fact, rainfall has not exceeded 1.00″ of rain, in a day, since June 4.
The outlook for September 2020 shows that the drought abatement is likely.
