Upgraded the weather PC this weekend and retired the old P4. It was maxed out at 512RAM and the continuous data collection and now web cam capture was bringing it to a crawl. A new UPS system was also installed.

The last in a series of disturbances brought a line of thunderstorms through last night. Some residual showers early this morning and a brief shower later this afternoon brought the 3 day total to about 2.3 inches. Much heavier rain fell about 25 to 30 miles north of here last night with portions of Joliet and Plainfield receiving between 3 and 4 inches. High pressure building in promises a great weekend and start to next week with much more comfortable temperatures and lower humidity.
A flood watch has been issued by the National Weather Service Chicago for northern Illinois including the Goose Lake area. Several rounds of thunderstorms are expected over the next 48 to 72 hour that have the potential to produce heavy rain. Significant flash floods can occur in July. During the period of July 17-18, 1996, a new state record rainfall was set in Aurora, IL when that location recorded 16.94 inches in less than 24 hours! Widespread disastrous flooding occurred as a result of the rainfall and subsequent runoff across northern Illinois. We could use some rainfall but let’s hope the total amounts remain well below record levels.
Replaced the fan in the daytime fan aspirated radiation shield in the temp/humidity station equipment. It operates on solar power and provides air flow across the sensor for more accurate readings.
High temperatures are expected to reach the mid 90′s today. The heat combined with high humidity will create heat index values of 105 or greater. The heat index is a measure of how hot it really feels. Learn more about heat and the heat index here.
Thunderstorms rolled through between about 1AM and 4AM here. There was some nice lightning displays and a decent 0.57 inch of rain in the manual rain gauge. The automated rain gauge reported 0.55 inch. There is about a 200 ft distance between the two and differences are not uncommon. Also, during a very intense rainfall, the automated gauge will not always be able to keep up with rain. It uses a tipping bucket type mechanism. Some more thunderstorms possible later today but the severe threat may be south of here…will have to wait and see. Happy Independence Day!
