Today signals the start of a three-day stretch of unusual heat and humidity for mid-May. A cool front sliding into the region late Friday will break the heat, perhaps with a round of showers and storms. It turns noticeably cooler over the weekend and mostly dry, although some more showers and storms could return toward the end of Sunday.

Today (Wednesday): It actually feels pretty good early on today. Temperatures are refreshing and it’s not all that humid — yet. But as the morning wears on and especially into the afternoon, the sun beats down and it becomes hot and muggy. Highs are around 90 — and Washington’s record high for the date of 92 degrees from 1974 may be in play. Winds are light from the southwest. Confidence: Medium-High

Tonight: Partly cloudy and balmy — it feels like your typical July night, six weeks early. Lows hover in the upper 60s to low 70s. Confidence: Medium-High

Tomorrow (Thursday): This is probably the week’s hottest day. We’ll have lots of sunshine, not much breeze and muggy, hot conditions. Highs reach the low-to-mid 90s and it may feel even a few degrees higher factoring in the humidity. Confidence: Medium-High

Tomorrow night: Under partly cloudy skies, it’s another warm and overnight period with lows 65-70 in our cooler areas to 70-75 downtown. Confidence: Medium-High


Friday marks the week’s final day of summerlike stickiness. We’ll make another run at 90 degrees, but we’ll have a chance of a few showers and storms into the late afternoon and evening as a cool front drops down from the northwest. A few showers could linger overnight with lows near 60. Confidence: Medium-High

High pressure parked to our north directs cooling winds southward Saturday. But we should have enough sunshine to push highs into the pleasant mid-70s. By Sunday, the high pressure system retreats to the northeast, and warmer air tries to push into the region from the south. But there’s a chance we get caught up in a wedge of cloudy, cool conditions — limiting highs to 70-75. Late in the day, a few showers and storms are possible. Confidence: Medium
