Loudoun County Weather Outlook for Wednesday, September 30, 2026

🌡️ Summer Feel Today

Good Wednesday! We are halfway through the week, and it is going to feel more like summer. After some early morning fog, temperatures climb into the low 80s today with plenty of humidity.

🥵 Even Hotter Thursday and Friday

Thursday will be hot and humid with highs in the mid to upper 80s. Friday stays hot with highs in the upper 80s and a chance for some afternoon and evening showers.

🌧️ Weekend Rain Trending South

The weekend forecast has changed quite a bit. The rain we have been watching is trying to move north from the south, but the latest trends keep most of it farther south. Saturday now looks mainly dry with highs near 70.

There is still a chance some rain makes it far enough north to affect us Sunday, but that remains uncertain. At this point, I am not convinced Sunday will be a washout, even if some rain does make it into our area.

My friend over at Jay's Wintery Mix has been talking about the models trending southward too. Hopefully that is not a trend we have to deal with this winter when snow is involved! 😄

🍂 Much Cooler Next Week

Sunday and Monday should only reach the mid-60s, and by Tuesday it will only be around 60 degrees. The overall pattern favors cooler weather next week, with temperatures running a little below normal.

It is fall, so I guess that is okay! 🍂

The Forecast:

Wednesday: Hi 81 ⛅ Lo 60 ☁️ – Patchy morning fog, then partly sunny; mostly cloudy overnight

Thursday: Hi 85 🌤️ Lo 62 ☁️ – Mostly sunny with a partly cloudy night

Friday: Hi 87 🌦️30% Lo 59 🌧️30% – Mostly sunny with a chance of afternoon showers; showers possible overnight, mainly before 2 AM

Saturday: Hi 68 ☁️ Lo 53 🌧️40% – Mostly cloudy; shower chance mainly overnight after 2 AM

Sunday: Hi 65 🌧️50% Lo 53 ☁️ – Mostly cloudy with a chance of showers; slight shower chance overnight before 2 AM

Monday: Hi 66 🌤️ Lo 41 🌙 – Mostly sunny and clear

Tuesday: Hi 60 ☀️ Lo 39 🌙 – Sunny

Loudoun County Weather Outlook for Monday, September 28, 2026

☁️ Cloudy Monday, Some Improvement Later

Good Monday to you! It will be a cloudy day, but the clouds should slowly thin and break up some later. Highs will be around 70°.

🌤️ Warming Up This Week

After some morning fog Tuesday, highs climb into the low to mid 70s. Wednesday gets warmer near 80°, followed by the mid 80s Thursday. Friday should be around 80°.

🌧️ Rain Chances Increase Late Week

Rain chances may increase late Friday, with a better chance for some rain as we head into Saturday and Sunday. Temperatures should cool back into the upper 60s to around 70°.

The Weather Prediction Center is currently showing an inch or more of rain for our area with this late week system. I think that may be a little generous at this point. We will have to see how things evolve as we get closer.

🥶 Cooler Pattern Ahead?

The longer range continues to suggest temperatures near normal at first, followed by a turn below normal farther out. This fits with the expected downstream pattern following the recurvature of a western Pacific typhoon.

Could it eventually get cold enough for frost? It is possible, but that is still far enough away that we will just keep watching the trends.

The Forecast:

Monday: Hi 70 ☁️ Lo 59 ☁️ – Cloudy with northwest winds 8 to 11 mph, gusts to 18 mph. Mostly cloudy overnight

Tuesday: Hi 75 🌤️ Lo 57 ⛅ – Mostly sunny with northwest winds around 6 mph. Partly cloudy overnight

Wednesday: Hi 80 🌞 Lo 59 🌙 – Sunny and warmer

Thursday: Hi 85 🌤️ Lo 63 🌙 – Mostly sunny and warm

Friday: Hi 82 🌦️20% Lo 58 🌧️20% – Mostly sunny with a slight chance of afternoon showers. Showers possible overnight

Saturday: Hi 70 ⛅30% Lo 55 🌧️30% – Partly sunny with a chance of showers. Showers possible overnight

Sunday: Hi 69 ⛅40% Lo 54 – Partly sunny with a chance of showers

Have a great Monday!
