Today (Thursday): Morning fog and low clouds may require a little time to burn off especially east of the city. However, partial sun should grace our skies later in the morning and into the afternoon as light winds come from the south. That should push highs to near 80 to the mid-80s. Thundershowers are likely to pop again in the afternoon but should be less numerous than yesterday with an overall 50% chance of a given location getting wet. Confidence: Medium

What is the Storm Threat Level?

Tonight: Any lingering showers (30% chance) should die during the early-to-mid evening. Breezes are light from the south. Evening readings in the comfortable 70s drop into the 60s for overnight lows. Confidence: Medium

Tomorrow (Friday): Clouds may bother us for a bit in the morning but sunshine becomes more plentiful throughout the day. This kicks temperatures up a notch with highs in the mid-to-upper 80s. The chance of a thunderstorm is still there but down to about 20-30%. So probably not a widespread threat to the mad dash out of town, but still something to check back with us on. Confidence: Medium

Tomorrow night: Stars finally make an appearance as clouds are much more limited. Evening readings are quite warm, in the upper 70s to low 80s, so dress light. Lows range from the mid-60s in the burbs to near 70 downtown. Confidence: Medium-High


Saturday is a true summer day with mostly sunny skies and toasty temperatures. Highs should punch into the upper 80s to low 90s, and moderate-to-high humidity means an afternoon heat index into the mid-90s. If you aren’t at the beach or in the mountains, hopefully the pool is open, or the A/C is turned up if you’re indoors. Just a slight chance of an afternoon thunderstorm. Saturday evening readings are in the low-to-mid 80s and overnight lows end up in the upper 60s to low 70s. Confidence: Medium-High

For those of you out of the city glare Saturday evening, take a look at Venus setting about an hour after the sun. With binoculars you can see it is a crescent, soon to be a black dot as it crosses the sun on June 5.

Sunday and Memorial Day promise to keep the heat going (could be record-setting heat for Dulles) with partly sunny skies and light breezes. With highs in the upper 80s to low 90s Sunday and low 90s Monday, keep the water handy whether it’s tennis, soccer, softball, or just about anything else outdoors. Once again, afternoon heat indices should reach at least the mid-90s. We do have a 20-30% chance for a thundershower to sneak in from the north. Sunday and Monday evenings are summery as lows only fall to the mid-60 to low 70s. Confidence: Medium


The beach forecast is a fairly uniform one this weekend with plenty of sun, so don’t spare the SPF!

Delaware/Maryland beaches should see highs climb from the upper 70s Friday to mid-80s on the weekend with the chance of a thundershower around 20% or less. Waves of 1 to 3 feet and water temperatures around 60 will be the norm.

Virginia beaches see highs in the upper 70s Friday rising to the mid-to-upper 80s on the weekend. Rain chances are minimal. Look for 1 to 2 foot waves and water temperatures in the low 60s.

New Jersey beaches see highs warm from the mid-70s Friday to low 80s by Sunday/Monday with just a 20-30% chance of thundershowers. Waves are only 1 to 2 feet and water temperatures are nearly 60.
