BREAKING NEWS Amtrak has announced delays along northeast corridor due to police activity on line between Philadelphia and Trenton, New Jersey

Weather from NBC Storm Team 4 — Updated 12:30 p.m., Aug. 1, 2015

The first weekend of August will start off almost as perfect as it gets! With high pressure over the Tennessee Valley and a weak disturbance over the Mid-Atlantic States, we will see a blend of sunshine an clouds with temperatures zooming into the lower to middle 90s Saturday. Despite the heat, however, it will feel quite comfortable as the dew points–which directly measure moisture content in the atmosphere–will be in the lower to middle 60s which is a Blessing in the summertime. Tonight looks pretty clear and tranquil with a bit of patchy fog possible; lows will be in the lower 70s in town with 60s in suburbs. Tomorrow will be another spectacular August day with abundant sunshine and highs in the lower to middle 90s with continued manageable humidity levels. The weather at the Delmarva beaches this weekend will also cooperate nicely with sunshine and highs in the middle to upper 80s both days with water temperatures in the middle 70s.

The new work week, however, will bring some unwelcome changes. As high pressure slides eastward and a cold front marches southeastward from the Great Lakes, hotter and more humid air will be drawn northward into the Mid-Atlantic. Our dew points will climb into the upper 60s by Monday so we will really feel that humidity back. With the help of some sunshine and that southerly breeze, temperatures will soar into the middle 90s with heat indices–a “feels like temperature” combining heat and humidity–approaching 100 degrees. As the front approaches Monday evening and night, we may see an isolated storm across our northern suburbs but most communities will remain dry. The cold front will stall to our south Tuesday but it will be close enough to keep the risk of a shower or storm in the forecast. Otherwise, the weather will stay pretty hot and humid Tuesday and for much of the new workweek.

In the meantime, enjoy this fabulous first weekend of August and stay cool!
