@packie7b Yup, the first thing I put in was June 29, 2012 lol

(1/3) Ever wondered what the weather is going to be like during your road trip? Here's an updated version of my route planner app that I released a couple years back (modernized with Claude!).

With lows each night falling into the 40's and 50's, this will be perfect weather for starting to increase fall foliage coverage across the area.

[FirstinWeather - Rohan Shroff @FirstinWeather]

Beautiful weather in store for the Mid-Atlantic the next week as a trough dives down from Canada, bringing lower dewpoints and cool overnight lows with it. Great weather for fall foliage acceleration!

(3/3) Clicking on a specific location marker allows you to see the weather for that location and the assigned grade. Finally, you also have the option to see overlays like SPC severe weather outlooks, excessive rainfall, and WPC outlooks.

(2/3) The web page allows you to select your departure time and then see the weather every hour based on your selected departure time. HRRR model forecasts are overlaid as well.

@Jacob_Feuer Sadly the entire institution/administration seems more preoccupied with PR rather than addressing the systemic issues and culture.

[FirstinWeather - Rohan Shroff @FirstinWeather]

Fall like weather should continue into next week, as lower dewpoints are advected in from the north, leading to beautiful weather.

[FirstinWeather - Rohan Shroff @FirstinWeather]

The Mid-Atlantic has abruptly entered fall after a warm start to September. Courtesy of a strong high in Canada, and a low off the coast, northeasterly winds have advected a cool maritime airmass and wet weather for much of the region. Many areas have seen 1-2 inches of rain!

speechless. at this point, we're talking $7/gal diesel becoming a possibility in the days ahead in more places, specifically Great Lakes- MI, IN, OH, IL (less so WI- lower taxes)

[Matthew Cappucci @MatthewCappucci]

In case anyone's keeping score, we had about 12,000 cloud-to-ground lightning strikes in the Maryland/DC/VA/Delmarva vicinity last night. (And that doesn't include the ~70-80% of flashes that don't strike the ground.)

[FirstinWeather - Rohan Shroff @FirstinWeather]

Wow, some intense and electric storms passing through the DC area!

[FirstinWeather - Rohan Shroff @FirstinWeather]

This is just positively absurd...
The acceleration in global warming that will inevitably result from this el nino event is concerning, not to mention for very volatile weather for the upcoming months.

[FirstinWeather - Rohan Shroff @FirstinWeather]

@LopWx What an incredible storm! Was surprised there wasn’t atleast a special weather statement.

[FirstinWeather - Rohan Shroff @FirstinWeather]

Too early to call this the first taste of fall?

[FirstinWeather - Rohan Shroff @FirstinWeather]

This is all courtesy of a rather deep trough for this time of year, which will act as the trigger. Potential limiting factor is widespread cloud cover in the morning keeping a lid on instability.

[FirstinWeather - Rohan Shroff @FirstinWeather]

With highs in the upper 80's to low 90's tomorrow, impressive CVA, and more than enough shear, we have the potential for 1-2 rounds of storms Tuesday into early Wednesday morning. SPC has a level 3/5 risk, with primary threat being damaging winds.

[FirstinWeather - Rohan Shroff @FirstinWeather]

Going to be some very smoky air tomorrow!
