Always a human at the helm: Updated around-the-clock by Capital Weather meteorologists.
What’s Happening Right Now
Imagine you’re outside right now — here’s what you’d feel:
- Clouds are moving in like a thick blanket across the sky
- Temperatures are dropping from the 70s — it’s getting cooler
- No rain yet — showers are waiting until late tonight while you sleep
Detailed Forecast: Day by Day
Tonight (Friday Night)
- Sky: Turning cloudier and more humid (sticky-feeling air) through the evening
- Rain: Showers and maybe some thunderstorms try to sneak in from the south before dawn (that’s around 4–6 AM)
- Temperatures: Lows in the mid-60s to around 70°F
- How sure are we? Medium-High confidence — we’re pretty sure about this part
Saturday (Tomorrow)
This one is tricky — the weather models (computer forecasts) are arguing with each other:
| Scenario A (Drier Afternoon) | Scenario B (Wetter All Day) |
|---|---|
| Morning showers → then mostly dry afternoon/evening | Rain continues at times through afternoon into evening |
| Current trend leans this way | Less likely, but still possible |
- Feels like: Muggy (warm + humid) — highs in the mid-70s to near 80°F
- How sure are we? Medium confidence — it’s a toss-up
Important Point: If you have outdoor plans Saturday, pack a rain jacket just in case, but don’t cancel — the trend is toward a drier afternoon!
Saturday Night
- Another round of showers and storms possible — maybe evening, maybe overnight
- Fog could form late at night when winds go calm
- Rain totals could vary a LOT by location:
- North & West of the Beltway (that’s the highway loop around DC — think Rockville, Fairfax, Loudoun): ~0.25 inches (light)
- South & East of the Beltway (toward Southern Maryland — think Bowie, Waldorf, La Plata): 1 inch or more (heavy)
- Lows: Humid 60s
- How sure are we? Low-Medium confidence — this is the shakiest part of the forecast
Sunday
Finally — a nice day!
- Sky: Partly to mostly sunny
- Rain: Only a slight chance of a stray shower
- Humidity: Slowly dropping — it’ll feel more comfortable
- Highs: Near 80 to mid-80s
- How sure are we? Medium confidence
Sunday Night
- Clearing skies, calm winds, probably dry
- Much more comfortable — lows in the upper 50s to mid-60s (open the windows!)
- How sure are we? Medium confidence
Looking Ahead: The Workweek (Monday & Tuesday)
A blissful start to the workweek!
| Day | Sky | Humidity | Rain Chance | Highs | Confidence |
|---|---|---|---|---|---|
| Monday | Plenty of sunshine | Comfortable | Near zero | Low to mid-80s | Medium |
| Tuesday | Plenty of sunshine | Comfortable | Near zero | Low to mid-80s | Medium |
Mid- to late week: Shower and storm chances may return with a bit more heat and humidity.

FAQ: Your Questions Answered
1. What is "the Beltway" and why does it matter for rain?
The Beltway is I-495, the highway loop around Washington, DC. Meteorologists use it as a handy landmark. In this forecast, where you live relative to the Beltway changes how much rain you might get — areas south/east (Southern Maryland) could see 4x more rain than areas north/west.
2. What does "confidence" mean in a forecast?
It’s how sure the meteorologists are.
- High = "We’re very confident this will happen"
- Medium = "Likely, but could change"
- Low = "It’s a guess — don’t bet on it"
Saturday night has "Low-Medium" confidence — so stay flexible!
3. What does "muggy" mean?
Muggy = warm + humid. The air feels thick and sticky, like you’re walking through soup. Sweat doesn’t evaporate well, so you feel hotter than the actual temperature.
4. Why do models disagree on Saturday?
Weather models are like different chefs using the same ingredients but making different dishes. They all see the same data but calculate the atmosphere’s future differently. When they disagree, forecasters tell you both possibilities so you’re prepared.
5. Should I cancel outdoor plans for Saturday?
Not necessarily. The trend is toward a drier afternoon. But bring a rain jacket and have a backup plan (like a covered pavilion or indoor option) for the morning hours.
