Loudoun County Weather Outlook for Tuesday, June 25, 2024

Heating back up today, but the humidity will only slowly increase. 
It will be hot tomorrow, but how hot it is will depend on how soon clouds arrive, and, potentially, showers and storms. The storms tomorrow could be strong to severe, posing a risk of strong winds. 
More reasonable summer temps return on Thursday and Friday. We have more 90s coming this weekend, but scattered showers and storms are also possible. 
The forecast: 
Today: Hi 92 Lo 70 ☀️🌙 – Sunny with light and variable winds, becoming partly cloudy at night with southwest winds
Wednesday: Hi 97 Lo 68 🌤️⛈️ 50% – 🥵 Partly sunny, hot, and humid with a chance of afternoon showers and thunderstorms, becoming mostly cloudy with likely showers and thunderstorms at night
Thursday: Hi 86 Lo 63 🌤️🌙 30% – Mostly sunny with a slight chance of morning showers and thunderstorms, becoming mostly clear at night
Friday: Hi 87 Lo 70 🌤️🌙 – Mostly sunny during the day, becoming mostly cloudy at night

Sunday: Hi 92 Lo 65 🌤️⛈️ 50% – Partly sunny with a chance of showers and thunderstorms throughout the day and night, becoming partly cloudy later
Monday: Hi 83 Lo 61 ☀️🌙 – Cooler, Sunny and mostly clear

Loudoun County Weather Outlook for Sunday, June 23, 2024

6/23/2024 – Another HOT ONE with a heat advisory, but relief is on the way as a front IS on the way today! It will swing through late today/tonight and MIGHT bring some showers and storms (we can hope!). With it being so hot, we also have the possibility of severe storms, the biggest threat being severe winds.
We will get a break tomorrow with less humidity and lower temperatures. 
Temps will return to the 90s Tuesday and even hotter Wednesday with another threat of heat advisory conditions. 
We have a better chance of showers and storms on Wednesday. Then, we will be a bit cooler on Thursday and have a few more showers. Unfortunately, temperatures will remain hot, from the upper 80s to the low and mid-90s, as we get into next weekend. The heat does not seem to want to go anywhere as we head into the following week. 
The forecast:
Heat advisory until 7pm
Sunday: Hi 95 Lo 72 ⛈️🌙 30% – 🥵HOT! Mostly cloudy with scattered showers and thunderstorms in the afternoon and evening

Loudoun County Weather Outlook for Tuesday, June 18, 2024

 Another Hot One! The temps will be about like yesterday. It is possible that we could head into drought conditions soon based on the current stream levels (attached are the current stream levels), recent dryness, and the sparse precipitation chances with this intense heat.  The ridge of high pressure causing the heat is almost on top of us! That is drying the atmosphere enough to reduce the chances of rain. It can still storm in these hot conditions, but that is not really possible until Saturday! 
We could see ridge disruptions with enough instability Saturday through Monday for some storms. I am still watching models to see if severe weather will occur during that time, but this is still far enough in the future to wait for better data to know the risk. 
The hot forecast:
Tuesday: Hi 92 Lo 68 ☀️🌙 – Mostly sunny, becoming mostly clear
Wednesday: Hi 89 Lo 68 ☀️🌙 – Sunny and mostly clear
Thursday: Hi 91 Lo 71 ☀️🌙 – Sunny and mostly clear
Friday: Hi 95 Lo 71 🌤️🌙 – 🥵 Mostly sunny, becoming partly cloudy
Saturday: Hi 96 Lo 72 ⛈️🌙 30% – 🥵 Sunny with a chance of afternoon showers and thunderstorms
Sunday: Hi 95 Lo 73 ⛈️🌙 30% – 🥵 Mostly sunny with a chance of showers and thunderstorms
Monday: Hi 91 Lo 69 ⛈️🌙 40% – Mostly sunny with a chance of showers and thunderstorms
