A month ago this Sunday, on June 29, was the derecho after a 104-degree afternoon in Roanoke.

July 29 looks very different, with drier air having filtered in behind a cold front. We’ll likely see lows in the 60s — maybe a few mid to upper 50s in more outlying areas — but that dry air will help highs recover to 80s to low 90s by afternoon. You can never totally rule out a few isolated showers or storms developing in the mountains on a sunny summer day, but it appears moisture will be limited enough that such development is unlikely. Moisture is likely to rebuild for the work week ahead, with occasional disturbances and fronts from the northwest triggering occasional rounds of showers and storms.

I plan to take the day off from the blog on July 29, in contrast to the busy June 29.  Will tune back in late Sunday or early Monday.
