[6:20PM] While most of the area will be dry this evening, a few very isolated sprinkles may be able to work through some drier air through the night. The rainfall will not amount to much. Only a few hundredths of an inch may come down for those who do see any rain.
Pending we don't see any measurable rainfall before midnight, this May will go down as the driest on record for Rockford. Only 0.47" of rain fell this entire month at the airport, compared to the average 4.18" rainfall we typically see in May. Especially remarkable given how long ago some of the other top 5 have been!
A tiny bit of moisture may produce few sprinkles from time to time from late evening through the overnight hours, but most of the area will remain dry at any given time. Whatever rain does fall probably will not amount to much, likely less than a tenth of an inch for those who do see rain.
Another round of dry high pressure will then take hold early in the week, bringing pleasant afternoons and cooler nights. Monday and Tuesday night could feature lows nearing the upper 40s in a few locations!
But the lack of humidity will not last for long. As that area of high pressure slides away, surface winds will turn to come from the Southwest. That will bring an increase in moisture, especially at the surface. Dew points will likely climb into the 60s by Friday evening. A more unsettled pattern will develop as a result, with at least isolated chances for some showers and storms beginning Thursday night. While it may not be a soaking rainfall for everyone, prospects for much-needed rainfall look a little better through the first week and half of June.
