FORECAST IN DETAIL
I would wave a white flag but it’s too much effort in this sweltering fix we find ourselves in … for days. The only bright spot is Washington’s record today of 106 (set in 1930) looks secure but 100 cannot be ruled out in parts of the area not just today, but also tomorrow and into the weekend. Storms are few through Friday but odds improve markedly over the weekend, probably coming too late in the day to offer much relief from the searing sun.
Today (Thursday): The day starts off clear and muggy and goes downhill from there. Highs reach the mid-to-upper 90s with 100 not out of the question. Heat indexes are likely to reach 100-105. Northwest breezes are too light to take an edge off the swelter. Isolated storms (10-20 percent chance) are not likely to offer much cooling relief either, except in the immediate area of the showers. Confidence: High
Tonight: Evening readings only slowly falling into the 80s make outdoor tables easy to come by, but probably not a good idea. Winds go calm and humidity levels are quite uncomfortable. Lows only fall to the mid-70s to near 80. Confidence: High
Tomorrow (Friday): A few clouds do little to halt the steady rise in temperatures through the day and humidity levels are high enough to add to the misery. Highs top out in the mid-90s to near 100 (heat index values up to 105 or so). Westerly breezes offer little cooling effect and only a lucky few see an isolated storm (chance of storms is 20 percent). Confidence: High
Tomorrow night: Isolated storms could linger into the evening but, for most, just a partly cloudy, it’s a muggy end to the day. Overnight lows settle in the mid-70s to near 80. Confidence: High
A LOOK AHEAD
Saturday is a trickier situation as storms in the Midwest approach during the day. This could at least add some clouds to buffer against the beating sun. Humidity levels are still likely to be oppressive and highs still rise well into the 90s. Some storms should manage to reach the area by afternoon and chances for a shower linger well into the evening. Up to half of the area has a decent chance of getting wet and a few heavy downpours are possible. Overnight lows dip into the 70s. Confidence: Medium
Clouds will be more plentiful on Sunday and scattered storms are a possibility at any time — best chance is in the afternoon. The timing of storms is very important because if the clouds/showers don’t materialize, highs could reach the low 100s. But for now the thinking is we “hold” in the 90s. Again, about half the area should see some measurable rain. Lows once again range through the 70s. Confidence: Medium
Monday should be just a tad less hot but humidity levels are unlikely to budge. Look for partly sunny skies, scattered storms and highs in the low-to-mid 90s. Confidence: Medium
