FORECAST IN DETAIL

While the tragic tornado season remains in full swing in the central U.S., here in the mid-Atlantic we’ve settled into an early-arriving summer pattern. So far our somewhat humid 80s have been tolerable, but we may not feel the same about 90, which we could near or eclipse a few times over the next several days as typical summertime storm chances persist.

Today (Wednesday): Partly to mostly sunny skies send temperatures toward what’s becoming a familiar spot for highs as of late - the mid-80s. A weak surge of higher pressure tries to keep our shower and storm chances down from the past couple days. A couple late afternoon/evening storms are still possible, but they’re probably isolated at best with the overall rain chance around 20-25% for any particular location. Confidence: Medium-High

Tonight: After the chance of an isolated evening shower or storm, overnight lows continue to be mild-mannered - in the mid-to-upper 60s under partly cloudy skies. Confidence: Medium-High

Tomorrow (Thursday): Maybe a passing shower with a warm front in the vicinity during the morning. But the main story is a significant step up in the heat and humidity thanks to flow from the south ahead of low pressure in the Midwest. Highs head for the upper 80s to low 90s with afternoon/evening shower and storm chances edging up to around 30%. Confidence: Medium-High

Tomorrow night: The evening shower/storm chance (30-40%) wanes overnight, while your A/C keeps humming all night long with lows some 15 degrees above average - in the upper 60s to low 70s. Confidence: Medium-High

A LOOK AHEAD

The partly sunny, hot and humid routine continues Friday as highs make a run at the mid-80s to near 90. In the afternoon and/or evening, an approaching cold front could destabilize the atmosphere enough for some strong to severe storms, with overall shower/storm chances around 50-60%. Confidence: Medium

Memorial Day weekends can really run the gamut, ranging from soggy, drab 60s and 70s, to mid-summer warmth and humidity. This Memorial Day Weekend shapes up squarely in the latter category. Highs should rise from the mid-80s Saturday to the upper 80s to low 90s Sunday and Monday, with lows each morning in the mid-60s to low 70s. Given the heat and moderate humidity, there’s the potential for an isolated late-day t’storm each day. Confidence:Medium
