It has now been more than 2 weeks since the last measurable rainfall in Rockford, and we haven't seen much even going back to the end of July either. The last 4 big rainfall events at the Rockford airport have not amounted to much in aggregate, and it's been almost 2 months since the last rainfall of more than 1". In September, we have only seen a trace amount of rain so far to start the month, tying the driest start to the month on record.
Temperatures will once again fall to the low 60s for many of us, owing to some clouds and a teeny bit of moisture lingering near the surface. Another mild night on tap with light winds from the ESE.
It will be warm and dry in the Stateline for a few more days, with highs well into the 80s Monday and Tuesday under a bit more sunshine. Overnight lows will be a tiny bit lower down in the 50s due to lack of moisture and cloud cover that would normally indicate mild nights.
There will be a slightly higher risk for brush fires and grass fires this week. Warm temperatures and a lack of rainfall will lead to low humidity levels and dry vegetation. Limit any outdoor burning, and be sure to have a safety plan in place to put out any fires before they get out of control.
The dry weather will stick around a bit longer due to a blocking pattern in the atmosphere, with ridging and high pressure to the East while troughing and low pressure remains West. This places us within a dry Easterly flow aloft, keeping moisture and associated rain chances low through much of the week. We may see a slight increase in cloud cover mid-week from a decaying tropical system moving in from the Carolinas, but no rainfall expected until the pattern breaks. This likely arrives sometime next weekend, but until then, we will continue to see a dry and warm summer-like forecast.
