Highs in the 90s start tomorrow, with storm chances Tue-Wed

Today might get to 90, but the real story lies in the next seven days, where highs are expected to reach from the lower 90s to lower 100s Monday through next Sunday (and beyond?). Thursday through Saturday has been fairly consistent in being the hottest days, with highs in the 97-103 range. The forecast hasn’t been changing all that much, so confidence is high that we’ll see some very hot temperatures at the end of the week. Lows will typically be in the mid 70s during this period.

A weak cold front will provide the region with a chance of showers and thunderstorms Tuesday and Wednesday before the big ridge builds in. There will still be a slight chance of showers and storms through the end of the week, but the next “good chance” for rain will be around Monday of next week.

The First Annual American Weather Conference is being held in Baltimore, MD this weekend… it’s going to be a bit uncomfortable with all that heat! I’ll be in attendance for most of Friday (after noon) and all of Saturday.
