FORECAST IN DETAIL


A cold front is coming! This incoming air mass boundary is working to tap into the vast moisture supplies in the Southern U.S., so that it should send some heavier downpours our way today into maybe this evening. While we need the precipitation, the occasionally inclement conditions hinder transportation and other outdoor activities. After that, high pressure builds into New England and eastern Canada and sits there for Wednesday, Thursday, Friday, Saturday, Sunday, and even Monday of next week! This “Tortoise” high keeps us near to below normal on temperatures and mostly dry.

Today (Tuesday): Showers and storms make today a watch-the-radar day. Most likely impacts should be around the midday hours and this afternoon into early evening. Some rainy episodes could be heavy, and I’m thinking most areas could see between .25” to .75” and locally higher depending on downpours. Cloudy skies, but highs still manage the low-to-mid 80s with winds from the south and southwest at 5-10 mph. Confidence: Medium

Tonight: Showers and possible thunderstorms mainly this evening with a 30% chance of overnight left-overs. Lows drop into the middle 60s in the outer suburbs to only around 70 in the city. Winds shift and come from the north at 5-10 mph. Confidence: Medium

Tomorrow (Wednesday): Partly sunny skies with noticeable cool breezes from the north (10-15 mph). Highs range from the upper 70s to low 80s. Confidence: Medium-High

Tomorrow night: Partly cloudy and cooler with lows in the upper 50s to the middle 60s in the city. Confidence: Medium-high

A LOOK AHEAD

Thursday is partly cloudy with a 30% risk of a mainly afternoon light shower. The better chances are over on the Delmarva though. Highs aim for the low-to-mid 80s. Thursday night is partly cloudy and cool with lows in the upper 50s to mid 60s again. Confidence: Medium-high

Friday and the weekend offer similar atmospheric circumstances due to stalled high pressure well to our north. Onshore Atlantic flow offers occasional daytime clouds intermixed with partial sunshine. Outside risks of a light sprinkle or shower exist too. Temperatures continue to run seasonal to slightly cooler-than-normal with highs in the low 80s and lows in the upper 50s to middle 60s. Confidence: Medium

With no more 90s in the forecast for this week and upcoming weekend, our next best chance to reach or exceed the 90-degree mark is around Tuesday of next week or later. How about that!?
