KEY MESSAGE 2...Increasing heat and humidity this week with
afternoon thunderstorm chances Wednesday through Friday.
Summerlike heat and humidity return this week as an anomalous mid-
level ridge and surface high pressure expand into the region.
Tuesday kicks off the warming trend, with 850 mb temperatures
climbing into the middle to upper teens, supporting daily afternoon
highs in the upper 80s to lower 90s. NWS HeatRisk guidance
highlights the potential for heat impacts, with widespread moderate
impacts and isolated pockets of major impacts, particularly across
urban centers by late week. One possible fly in the ointment will be
cloud cover and storm coverage during the middle to latter half of
the week, which could keep temperatures just cool enough to avoid
the need for heat-related headlines. Nevertheless, those who work
outdoors should prepare for another stretch of unseasonably warm
temperatures. Additionally, there will be little in the way of
nighttime relief, with overnight lows generally remaining in the 60s.
