I. We can already feel a difference in the nature of the airmass this morning, but there’s a much bigger push of dry air inbound tonight. By Monday morning, dew points across central Indiana will fall into the 40s and 50s- a far cry from the oppressive “jungle-like” dew points from last week. Talk about a breath of fresh air. The good news in this pleasant airmass will hold through the middle of the week.

II. While we can’t totally rule out a shower this afternoon, most of the period will remain rain-free between now and Wednesday. Look for plentiful sunshine through this period as well.

Rain and storm chances will return towards the latter part of the week. While we’re not expecting any sort of washout, it’ll be a good idea to have a Plan B in mind from Thursday through the weekend in the event a storm cluster threatens from time to time.

III. Over the next couple weeks, the primary pattern drivers continue to look like a combo of the EPO and PNA- both of which will, for the most part, be in favorable phases to deliver seasonal to slightly cooler than normal conditions across our neck of the woods. At times, it’s appeared like the MJO will start to amplify, but that hasn’t been the case and doesn’t appear to be a big player in our pattern through mid August, at least. Bottom line, our idea is that August features seasonal temperatures, as a whole, with slightly above normal rainfall throughout central Indiana. (For perspective, the average high at IND in August is 84.3° with an average low of 65°. On average, we pick up nearly 3.5″ of rain during any given August).

The most anomalous and long-lasting heat should continue to be featured across Plains and points west with coolest anomalies across the Northeast.
