Springtime storms threaten to disrupt afternoon and evening activities today for the second straight day. It’s another warm and humid one, but tomorrow offers a noticeable change of pace with more rain possible but highs only in the 60s under overcast skies. Friday is a little warmer and perhaps a bit brighter, followed by what could be a fairly fabulous weekend weather-wise.

Today (Wednesday): Warm and humid continues to characterize our weather today. Morning temperatures start out mild, rising through the 70s, before afternoon highs likely max out somewhere in the 80s under partly sunny skies. After a 20-30% chance of a morning shower or thundershower, we’ll see shower and storm chances increase to 40% by early-to-mid afternoon and 50% by late afternoon. Winds should be light from the west-northwest near 10 mph, except stronger with any strong storms, which could feature heavy downpours as well. Confidence: Medium

Tonight: Shower and storm chances increase to 60-70% for this evening into the overnight, as clouds dominate and winds shift to come from the east-northeast. The air dries out just a bit, but it’s still somewhat muggy and on the mild side, with lows mainly in the low-to-mid 60s. Confidence: Medium

Tomorrow (Thursday): Temperatures look like they’ll do a whole lot of nothing tomorrow as high pressure off the Northeast coast feeds in a cool marine flow. Periods of rain or drizzle are likely as overcast skies limit highs to the 60s. Winds are light from the east near 10 mph. Confidence: Medium

Tomorrow night: Any showers should diminish by or during the evening, but drizzle or mist may linger longer. Clouds persist with lows in the 50s to near 60. Confidence: Medium

A LOOK AHEAD

I’m not convinced we’ll see much in the way of sun on Friday, but skies should at least be brighter than Thursday. A few showers or a bit of drizzle remain possible, especially in the morning. Winds continue from an onshore direction, which probably keeps us on the cool side again with highs near 70 to the low 70s. Clouds may finally start to break up Friday night, though we hold onto the chance of an isolated shower, as we look for lows in the mid-50s to near 60. Confidence: Medium

Saturday could still start with at least partly cloudy skies. But for the balance of the weekend we’re expecting high pressure to provide partly to mostly sunny skies, lower humidity, and pleasant highs in the upper 70s to low 80s. Saturday night lows settle in the 50s. Confidence: Medium-High
