Today: Mostly sunny and spectacular. Low 80s. | Tonight: Mostly clear. 50s. | Tomorrow: Sun mixed with clouds. Isolated shower/storm? Mid-80s. | Sunday: Partly cloudy. Isolated shower/storm? Upper 80s. | A Look Ahead | Get Express Forecast by E-mail


Welcome to your weekend (almost, maybe I’m thinking ahead?) of temperatures and dewpoints (the humidity factor) much closer to average for this time of year. You might actually be comfortable for most of this weekend — maybe a tad warm by Sunday — but much better than our record challenging heat from a few days ago. Right? Just a few clouds and perhaps a shower/storm or two is all we have to keep an eye on.


Today (Friday): Sunny and pretty darn spectacular overall. Highs near 80 or into the lower 80s with very low dewpoints mix with light northwest breezes from 5 to 15 mph. I might not need to warn you too much about UV if afternoon high cirrus clouds move in. The ice crystals in the clouds provide a nice extra shield against UV; however, it is essentially highest sun angle of the year — wear sunscreen! Find a product that has some SPF factor (30+) and put it into your daily routine. Confidence: High

Tonight: Breezes die down into the 5-10mph range, and skies stay mostly clear, with only periodic clouds from time to time. Lows in the upper 50s (chilly?!) downtown to near 50 possible outside the Beltway. Another night to refresh your household air by opening the windows! Confidence: Medium-High

Keep reading for the forecast through the (nice?) weekend...

Tomorrow (Saturday): Sun generally dominates through some periodic high-cloud filtering. These cirrus clouds are indicative of a warm front slowly passing through the area — not that we want an airmass regime change, right? Highs in the mid-80s seem likely but south of town may see some upper 80s. Humid-feeling air slowly filters in. Worth mentioning is a 10-20% chance of a shower or small thunderstorm. We’ll keep you posted as we watch radar later in the afternoon. Confidence: Medium

Tomorrow night: Mostly cloudy with a continued 20-30% chance of showers or thunderstorms. Lows in the upper 60s downtown, perhaps low-to-mid 60s in the more lucky suburbs. Confidence: Medium

Sunday: Partly sunny in the morning with more sunshine as the day wears on. Most showers should have moved eastward toward the DelMarVa. Highs in the upper 80s might actually feel okay, as we could have a light north breeze keeping dewpoints below a the tropical threshold we had during our record-breaking heat recently. We’ll run the risk of an isolated late-day storm yet again. Confidence: Low-Medium


Sunday Night: Partly cloudy and decently comfortable — well, at least not terribly sweaty, after the sun sets. Lows for metro area should bottom just before sunrise in the low-to-mid 60s. Confidence: Medium

Monday & Tuesday look pretty similar. Sorry it’s a 5-day workweek this week! You may have to miss a decent weather day or two while stuck indoors. Right now it appears to probably be mostly sunny with warmth up into the low-to-mid 80s. Perhaps a little warmer on Tuesday. Not terribly muggy, as it appears now, either day. But water vapor has a funny way of sneaking into our region easily this time of year — sometimes higher than we can predict several days out. Confidence: Low-Medium
