Loudoun County Weather Outlook for Saturday, August 29, 2026

🌤️ Pretty Nice Saturday

Good Saturday morning! Today looks pretty nice with highs in the low to mid 80s and humidity not too bad. A slight chance of a shower or storm is possible as a warm front pushes into our region. Enjoy it because things change tomorrow!

🔥 Heat and Humidity Return

Sunday starts our next hot stretch with highs in the upper 80s and increasing humidity. Monday reaches around 90°, followed by low 90s Tuesday and Wednesday. We stay near 90° Thursday and upper 80s Friday.

⛈️ Storm Chances Bring Some Relief

The saving grace will be chances for showers and thunderstorms, especially later in the week. Humidity increases too, so feels-like temperatures could climb much higher.

🥵 Hot Start to September

The heat may continue into September. We could cool slightly next weekend before another push of heat the following week. Some models have even hinted at temperatures approaching 100°, but that's still a ways out.

🍂 Not Great for Fall Lovers

El Niño may favor above-normal temperatures and drier weather this fall. Unfortunately, that could worsen our drought before we hopefully see a turnaround heading into winter.

Have a great Saturday and get outside and enjoy it!

The Forecast:

Today: Hi 83 🌞 Lo 65 🌙 – Sunny and pleasant
Sunday: Hi 89 🌦️20% Lo 69 ⛅ – Slight chance of storms
Monday: Hi 90 ⛅ Lo 71 🌧️20% – Partly sunny
Tuesday: Hi 93 ☀️ Lo 72 🌧️20% – Mostly sunny
Wednesday: Hi 94 🌦️20% Lo 73 🌧️30% – Storm chance
Thursday: Hi 91 🌦️30% Lo 69 🌧️30% – Storm chance
Friday: Hi 86 🌦️20% Lo 67 ☁️ – Slight storm chance

Loudoun County Weather Outlook for Friday, August 28, 2026

🌤️ Great Way to Wrap Up the Week
Friday is looking pretty nice with highs in the mid 80s, and there's a slight chance of a shower or storm developing late morning into the early afternoon. Nothing too impactful, and Saturday brings more of that same pleasant weather with highs again in the mid 80s.

🔥 Heat Cranks Up This Weekend
Sunday kicks off a warmup with highs climbing into the upper 80s to near 90. That summer like heat sticks around into next week, with temperatures near 90 or into the low 90s every single day Monday through Friday, another solid heat wave as we head into September.

🌦️ Slight Storm Chances Midweek
Wednesday through Friday of next week bring a slight chance of showers and storms, though nothing widespread, generally only around a 20% to 30% chance each day.

This hot and drier pattern is pretty typical for September during a strong El Nino setup, something we'll keep an eye on as we head toward winter.

The forecast:

Friday: Hi 84 🌦️20% Lo 62 – Isolated showers and thunderstorms possible in the afternoon, otherwise partly sunny

Saturday: Hi 83 🌞 Lo 64 – Mostly sunny and pleasant

Sunday: Hi 87 🌤️ Lo 69 ☁️ – Mostly sunny skies

Monday: Hi 90 🌤️ Lo 70 – Mostly sunny

Tuesday: Hi 91 🥵🌤️ Lo 72 🌧️20% – Mostly sunny with a slight chance of showers overnight

Wednesday: Hi 91 🥵🌦️30% Lo 71 🌧️30% – Chance of showers and thunderstorms during the day and overnight

Thursday: Hi 89 🌦️30% Lo 69 – Chance of showers and thunderstorms
