High pressure continues to settle across the area which has led to a sunny to mostly sunny day. Daytime highs for most of us will be in the upper 80s, but a few locations may hit 90. Humidity won't be too high though. Later Monday night, we'll have clear skies with seasonable lows in the 60s.
Tuesday will be a similar day, just a tad hotter with highs for all in the low 90s. However, humidity will be a little higher, which will push the feels like temperatures into the mid 90s. By Tuesday night, we'll have slightly warmer nighttime lows in the 70s.
As we head through the week, the high pressure system will gradually move eastward. This will cause our winds to shift to the south and will likely bring dangerous heat and humidity back into the Tri-States. Highs for Wednesday and Thursday are looking to be in the mid 90s, with heat index values above 100. More heat advisories may be issued by the National Weather Service.
