With numerous events taking place outdoors this weekend, here's a detailed look at this weekend's forecast.

There's a lot riding on the weekend forecast including events ranging from the Virginia Gold Cup to Nationals games and the Avon Walk for Breast Cancer - to name a few. So, will the weather cooperate? For the most part, I think it will. Let's start with Friday's weather then we'll jump into the details for the weekend including hour-by-hour forecasts. 

Thunderstorms are likely Friday afternoon starting around 4 p.m., and some storms may be strong and severe with gusty winds and large hail being the primary threats. If you plan to attend the Nats vs. Phillies game, be prepared for a potential delay. The storms will pop-up randomly, but I think there's a moderate chance that Nationals Park will get hit. Also, a few storms may develop into the night, but they should be more widely seperated.

Temperatures on Friday will be warm, and you'll feel the humidity in the air as well.  I'm expecting afternoon highs well into the 80s then dropping into the 60s by Saturday morning. Here's the hourly forecast:

 

 

 

 As for Saturday, there is a slight chance (20%) of storms both before sunrise and in the late afternoon hours.  My confidence is slim in storms developing on Saturday, and if one particular computer model is right, then no storms will develop at all, but that model is an outlier, so it's worth mentioning a minor chance. In terms of temperatures, expect morning numbers in the 60s then afternoon highs in the lower 80s with a hint of humidity. 

 

 

 

 As of now, Sunday looks rather cloudy in the morning with patchy drizzle and fog possible.  However, the clouds should break with sunshine by midday and afternoon. Precisely timing the erosion of the morning clouds is very difficult, but as of now, I'm expecting sunshine by 10 a.m. It will be cooler and more comfortable with lower humidity on Sunday as highs approach the mid 70s.
