September continues to be drier than normal. During the month that acts as our gateway to Autumn and the harvest season, Rockford picks up about 3.35″ of rainfall on average. As of today (September 26), the Forest City has only picked up 1.54″ of rain. We’ve got a long way to go to get back to normal.
Drought Monitor 09/24/13
The latest United States Drought Monitor update shows an expanded ‘Severe Drought’ for central Illinois, including areas as far north as southern Whiteside County. ‘Abnormally Dry’ conditions were present across almost 90% of the Prairie State. Wisconsin actually saw areas with ’Severe Drought’ conditions decrease ever so slightly, with ‘Abnomally Dry’ conditions covering 60% of the state.
Locally, the U.S. Drought Monitor continues to classify a small section of north central Illinois as drought-free, including metro Rockford. This can be a bit misleading. While it is true that Rockford has about a 5″ rainfall surplus for the year, the last three months have had significant rainfall deficits:
- July 2013: deficit of 2.03″
- August 2013: deficit of 1.67″
- September 2013: deficit of 1.41″ so far
The prospect for rain is in the forecast as the month of September comes to a close. However, the prospect for drought-busting rain is not in the forecast.
Staying Below Average
Models continue to trend low on our rainfall amounts for this Saturday evening and Saturday overnight. Rain showers are likely, but it appears we will only see our rain gauges pick up 0.30″ at most. The majority of the energy with this weekend’s system will stay in northern Wisconsin, Minnesota, and south central Canada. Some areas in the Northwoods could pick up over 1″ of rain.
