Dry start to September spills into the second half of the month

 It has been a very dry September so far, with only a trace amount of rain at the Rockford airport through Saturday. This is nearly 2 inches shy from where we should be halfway through the month now. Unfortunately, that has been paired with a dry summer aside from July. In total, we are in a rainfall deficit of 0.56" since June 1st.

The few rain chances that looked plausible over the weekend fizzled out before reaching us, mainly due to a lack of moisture and upper-level forcing to develop showers. We saw a few isolated showers and storms near the Quad Cities and Southward, but nothing in the Stateline.

Moisture remains limited, keeping what few showers that form very isolated in nature and mainly in Eastern Iowa both tonight and early tomorrow. Those who do see any rain will only see a brief shower that will not do much to cut into the rainfall deficit.

Unfortunately, the rest of next week also looks very dry with another push of dry air Monday and Tuesday. Many computer models keep the Stateline completely dry through the end of next week. Our next main chance for any meaningful rain likely won't arrive until at least next weekend.

Tomorrow will be another very similar day to what we saw Saturday with highs in the upper 80s and more sunshine filtered within upper-level clouds. Aside from the very small chance for a sprinkle early in the day, it will be another warm and dry day.

The dry stretch will be accompanied by unseasonable stretch of warmth as well, with highs into the mid and upper 80s through the forecast period. Overnight lows will be slightly above average, but the dry air should allow many nights to reach the upper 50s. Aside from the slim chance for rain early tomorrow, our next rain won't arrive until next weekend.
