I have 4 tickets to Indycar Nashville today we can’t use. Would love them to go to someone who can use them. @booksnburnouts.bsky.social @indycarweatherman.bsky.social

Here’s your #MusicCityGP raceday weather briefing: a bit more cloud cover today, so ambient/track temps should be just slightly cooler than Saturday. Dewpoint temps (good indicator of humidity) in low-50s (that’s good)..so ‘it’s a dry heat’. Light winds from north-northeast. #IndyCar #INDYNXT

No major forecast changes to make moving into the last race weekend of the #IndyCar season: upper-80s, dry, low humidity, northeasterly winds…and very similar conditions both days #MusicCityGP #Nashville

Midweek #MusicCityGP forecast update: still looks good. Warm but dry weekend. Upper-80s, but comfortable humidity levels..so no “heat index” to add on top of these temps. Still have one eye on Sunday rain chances…but not a threat for now. #IndyCar #INDYNXT

Early look at #MusicCityGP forecast: plan for mid-upper 80s. Humidity not too bad. Initial look appears dry, with better rain chances south…but way too early to lock that part in. #IndyCar

Your raceday weather briefing for the #SnapOn250 at #MilwaukeeMile: cool northwesterly flow continues today…expect ambient temps near 70° for the #IndyCar race…breezy at times. Post-race: a few isolated showers may pop-up early evening, just something to be aware of for those still in the area late

Here’s your Saturday morning weather brief: forecast tracking as previously described…early AM line of broken showers has moved through…clouds on back-edge should be lifting in next hour or so. West-northwesterly winds should get breezy by qualifying. #IndyCar

Wasn’t tracking…thanks!!
P1 got moved to 10am CDT in a direct swap with NXT practice.

No major forecast changes: front moves across Wisconsin Friday…won’t have too much moisture to work with but best shot for shower is overnight/early Sat…worth monitoring due to that early schedule for the first practice session. Sunday still the cooler of the two days. #IndyCar #MilwaukeeMile

Early look at the #MilwaukeeMile forecast: some rain to start the week then a shift to a drier pattern by Wed. Keeping an eye on a weak front late Friday with some potential showers…but for now Sat-Sun looks dry with great temps #IndyCar

Heat cranks up today at #PortlandGP: Sat evening final practice hit 88° amb/117° track. That’s close to where we’ll start the #IndyCar GP today at mid-day (at least for ambient). Other races: INDY NXT 75-80° this morning; USF Pro 2000 & USF2000 94-96° later today.

No major #PortlandGP forecast changes…was 82° Friday, warmer today, still expecting mid-90s Sunday. Earlier start time on Sunday will help #IndyCar avoid peak heat window…but a couple USF Pro Championship series races follow the GP and will be approaching the max temp that afternoon.

Initial outlook to start the week still looks pretty good, so minor tweaks only to #PortlandGP forecast: yesterday’s showers have moved thru, lingering clouds early today w/mid-70s..then progressively warmer til mid-90s Sunday (upper-90s Monday!)..hydrate for raceday #IndyCar

Here’s a first look at the #PortlandGP forecast: cloudy/showery weather Wed-early Thu..then dry but heating up Fri-Sun. Raceday temps potentially 10° above seasonal norms for early August. Humidity looks ok, so not expecting an excessive heat index to add on top of these temps. #IndyCar

Current satellite loop…you can see the fog/stratus clouds walking back up Salinas Valley as it burns off…it’s getting there, just takes time #IndyCar

Here’s today’s #JavaHouseGP forecast: similar to last couple days, mid-60s at start, clouds decreasing, winds increasing. If you’re wondering if moving warm-up from this morning to yesterday was the right call..it was..regional airports reporting ceilings 500-700’ again this morning #IndyCar

This is a pro-actively smart decision
Per BP: #INDYCAR Warmup will be at 7p ET / 4p PT on FS2 today at Laguna Seca ... so they don't have the same issues Sunday morning.

Nothing new with the forecast since previous updates…right now clouds are overcast between 400-700 ft with visibility between 2-3 miles…some patches where it’s worse…but everything should be noticeably improved by the time we get to #JavaHouseGP qualifying #IndyCar

I really don’t have any major changes to this forecast…only potential impact is possible low ceilings/visibility in morning…maybe some patchy light mist/drizzle in spots. Temps remain mild throughout. Winds should pick up each afternoon. #IndyCar
Here’s the Laguna Seca forecast for #IndyCar this weekend: no surprises in this one. 50s to mid-60s. Breezy in afternoon. Only potential impact is extent of low-level marine layer clouds in early AM..could get slight delay to early sessions (i.e. prac 2, warm-up), if conditions are right.

This is a great question: so the general rule for the tire safety limit is ambient temp + track temp > 100°…since the track retains heat, as long as amb temp is 50+°, the track temp will also be 50+°…so it’s good. When amb temps are < 50 then we have to hope the track temp can make up the difference
Is the minimum temperature limit that Firestone specifies in play for the potential impact?

7 am radar check: forecast on track with rain ending. True back edge of system is still dropping thru Georgian Bay..so a couple small blips on radar to watch…may get some drops out of low clouds as they pass through…but heavy/steady rain is done. No lake breeze today..it’ll remain a north wind
