Weather from NBC Storm Team 4 — Updated 7:06 p.m., July 31, 2015

Now, this refreshing weather is more like it! After sweating through some nasty humidity this work week, Friday brought a welcome change. In the wake of Thursday night’s cold front, drier air arrived on westerly winds and allowed dew points — which directly measure moisture content in the atmosphere — to drop from the tropical 70s into the more-tolerable 60s Friday. Despite highs into the lower 90s again throughout the area, it felt much better outdoors and this will continue into the weekend. Friday night looks pretty clear and tranquil with lows near 70 in town and 60s in suburbs.

Saturday will be a spectacular start to August with high pressure over the Tennessee Valley providing ample sunshine. Temperatures will warm quickly into the lower 90s but, once again, the humidity levels will remain manageable. Sunday looks like a carbon copy with continued hot but comfortable weather. The weather at the Delmarva beaches this weekend will also cooperate nicely with sunshine and highs in the middle to upper 80s with water temperatures in the middle 70s. By Monday, however, a cold front will march southeastward from the Great Lakes. Ahead of the front, southwesterly winds will draw warmer and more humid air into the region. We will see some sunshine and that will boost temperatures into the middle 90s with heat indices in the upper 90s to near 100 degrees. As the front approaches late Monday, we expect additional clouds with the risk of an isolated storm in the evening or night. The cold front will stall to our south Tuesday and close enough for the risk of a shower or storm. Otherwise, the weather will stay pretty hot and humid during the middle (to the end) of the new workweek.

In the meantime, enjoy the fabulous weekend weather have a safe weekend and stay cool!
