Drought Eases

I have recorded 1.89 inches of rainfall since last Thursday. The drought isn’t over yet, but there are signs that it is improving.

Most of Centre County is still experiencing a moderate drought. However, our little corner of the county is now abnormally dry. The outlook for the rest of September indicates equal chances for normal rainfall (about 4 inches on average).

Ice Storm

On Tuesday, December 17, our area experienced an ice storm. Freezing rain, supercooled rain droplets, froze on contact on many surfaces during the night.

About 0.16 inches of ice accretion was observed.

Also, snow squalls, on Wednesday, caused a pile up on I-80 that shut down the highway for 34 miles, in both directions, between the 178/220 North/Lock Haven exit in Clinton County and the 212B/I-180 West/Williamsport exit in Northumberland County.

Paws and Hot Asphalt

During a recent walk with my dogs, I decided to take along my infrared thermometer.

During the summer, it is important to remember that the pads of a dogs paws are subjected to hot surfaces outside. Since there are no sidewalks where I live, our dogs walk on asphalt, gravel or grass.

I took a few measurements during a walk today. It was sunny around 2:45 PM EDT, and I found that the temperature of the asphalt can reach 140 F. It became increasingly cloudy during my walk so the asphalt cooled off a bit.

The gravel along the side of the road is preferable at 100 F. Grass in much better, even if it is dry and brown. I measured 85 F for dry grass. Green grass was cooler at 80 F. In the shade, the green grass measured 70 F. Even concrete in the shade was better than asphalt at 90 F.

By contrast, at 7 AM EDT, the asphalt temperature was 76 F.

These readings show that asphalt can be harmful to your dog’s pads. Today the air temperature was in the low 80s. If it was above 90 F, it follows that asphalt can be greater than 140 F and could burn dog’s paws.

A simple check is to place your finger tips on the asphalt for a few seconds to see if it’s comfortable.

My Personal Weather Station

If you haven’t figured out by now, I am a retired meteorologist. I have installed my own weather instruments at my home in Stormstown. My primary station consists of a cluster of sensors for The Davis Vantage Pro 2 weather station.

Pictured is the tipping bucket rain gauge, thermometer, hygrometer, solar sensor, UV sensor and data transmitter. The transmitter has a battery that is charged by a small solar panel. The spikes are a deterrent to birds that can foul the rain gauge.

On a 30′ mast, near the instrument package, are a wind vane and anemometer.

Data are transmitted to my indoor displays. One of my displays has a data logger with a wired connection to an internet router.

With software, supplied by Davis, my data is downloaded to a PC for storage and analysis. My data are also uploaded to Davis WeatherLink, Weather Underground and The Citizen Weather Observer Program.

My secondary instrument cluster is a BloomSky package. On the left is a solar-powered barometer, thermometer, hygrometer and UV sensor package. It also has a fisheye WiFi camera. On the right are a solar-powered anemometer, wind vane and tipping bucket rain gauge. Data are sent to my router via WiFi and uploaded to BloomSky.
