FORECAST DISCUSSION
Normal high: 87°F / Normal low: 68°F
A frontal boundary has sagged to our south Tuesday afternoon, which has resulted in quiet weather on Delmarva, with showers and thunderstorms to our south and west. It has been quite muggy, though.
The frontal boundary will start to lift back to the north Tuesday night, which will slowly increase our chances of a pop-up thunderstorm overnight, but most folks won't get anything. With the muggy conditions, I am adding a mention of some patchy fog by sunrise Wednesday.
With the front lifting to the north, Wednesday is shaping up to be a rather unsettled day, but again, not a washout, and with storms not quite a widespread as previously thought.
Thunderstorms that develop are unlikely to be severe, but they will likely have frequent lightning and very heavy downpours. All of Delmarva is under a Level 1 threat (on a scale of 1 to 4, with 4 the highest threat) for flooding from these downpours Wednesday. Again, though, not everyone will see a thunderstorm.
Later in the week, things turn a bit more summer-like, with much warmer temperatures climbing up to the seasonably warm upper 80s and low 90s Thursday through Sunday. We'll continue to be humid, so heat indices will be in the 95°-100°F range. With that humidity, there will be daily chances for pop-up showers and thunderstorms.
In the Tropics: There are no areas of development interest at this time.
