4:30 est arrival for final line….so should be good to end 🤞

That last moisture yellow was basically a dissipating shower line going through..can’t see the sprinkles/drops on radar so may con’t to be an intermittent issue. Next major line is on track for 4:30-5 pm arrival…and will have to watch pop-ups ahead of it (as you see here near Bainbridge for ex)

Weakening…we’ll see what’s left…but would estimate sometime between 3-3:30 pm….no lightning

This is the next concern area to pay attention to in 60-90 min

Still looking ok…more or less threading the needle between these two waves…watching the pop-ups now east of Terre Haute but they’re still awhile away…should get an on time start #Indy500

I think so…though if by noon showers to the south can get squeezed a little to the east by the approaching wave out west, there’s a shot at threading the needle before second line of storms later this afternoon…still watching

Good morning! Here’s some quick thoughts on today..think forecast reasoning overall is same: AM showers..’drier’ gap (but need some cards to fall)..storms at the end. On to radar watching. #Indy500

This is a tough one and in some ways reminds me of 2024..complex set-up that really only become clear once we got to race morning. Evening updates not much help. Still think it’s pre-race showers..and a line of late afternoon storms as main protagonists. Another update in early AM.

Here’s where I’m at on this forecast. I’m leaning late AM shot…some clear time (but pop-up potential)…then second enhanced area late (i.e. two impulses triggering activity)…we’ll see what today’s data brings and update again tonight. (FWIW..don’t think we’re there yet, but Monday looks ok).

I’m working through the overnight model data this morning. I think the morning impulse I casually mentioned last night is actually a thing. At question is how that impacts/shapes rest of the afternoon. I’ll post some updated thoughts here later this morning.

My latest #Indy500 take: storm chance remains for Sunday..my best guess for now is as early as 2pm, late as 6pm..but timing not set. Also wondering if there isn’t a brief impulse that comes thru Sun morning with a shower..worth at least a mention but will see if it shows up in the overnight data

Kinda same…still showing chance of storms predominantly in afternoon…timing still a little fluid at this point. Will have a look at this evenings data and post an update tonight!

Snapshot for #CarbDay: think we can sneak practice in but it’s close…Wienie 500 higher chance of running wet. Rest of day rainy. No major changes to Sat or Sun from previous forecast right now…let’s get through tomorrow then shift focus on #Indy500 weather.

Wed #Indy500 forecast update: #CarbDay am dry, then rain rolling in from south…timing too close to say whether we can get the whole 2-hr practice time in (at least as it’s scheduled now). Sat looks better late. Sun still see an area of storm/shower development in central IN midday/afternoon.

Here’s my latest #Indy500 forecast: increasingly likely we get rain Friday…for now think AM is ok…#CarbDay practice maybe…but as we get to afternoon rain appears more likely. Wet pattern remains Sat…still looks like some drier conditions Sunday, but chance pop-up storms still look possible

For those wondering about practice today (1-3pm)…first hour should be OK…gets iffy after that whether they can get to 3pm. Keep in mind lightning will probably halt track activity prior to arrival of the actual precip.

Initial #Indy500 forecast: week starts with stormy Mon & Tue, then drying/cooler Wed-Thu. Gets murky after that. For now, think best rain chances later Fri…carrying into Sat…trending drier on Sun. Mention of possible afternoon pop-up storms Sunday for now..and we’ll see how forecast evolves.

Some strong/possible severe storms rolling in from west on Monday…will have to watch timing as could be racing that line with scheduled practice window (1-3 pm)

Today’s #Indy500 Qualifications weather: partly cloudy to mostly sunny and humid..will feel a lot stickier this afternoon than what we saw in practice earlier in week. South-southwest winds..breezier as we move through the day #IndyCar

#IndyCar #Indy500 Schedule:

Today has been called ☔️ Here is the schedule for tomorrow ⬇️ #Indy500

Here’s tomorrow’s forecast! Less weather drama hopefully 😂…will update in morning!

"UPDATE: Day 1 of PPG Presents Armed Forces Qualifying at @IMS has been rained out. On-track activity will resume Sunday with Practice 6 at 9:30 AM ET on FS2, followed by qualifying for the 110th Running of the Indianapolis 500." @indycarweatherman.bsky.social @indynathan.racing

So they started drying again but there’s still activity on the north side of this area in-line with IMS…heaviest rain will pass south so maybe it doesn’t completely reset progress made but they are definitely up against it if you’re 2 hrs to dry + 3 hrs to get 33 cars qualified..so race to clock now

So given they had decent downpours I’d call it 2 hours dry time from now (if they’ve even started)…the issue is gonna be what arrives within/after that time period which is gonna reset any drying that’s accomplished…radar looked like maybe a gap would develop…but filling in now

So…forecast, unfortunately, looks to be on-track…challenge is finding long enough gap in this for drying + running…think if there’s a chance this happens it’s most likely 3pm…but even that might be optimistic

Here’s where I’m at with the weekend forecast..timing is not as straight-forward as today’s rain as it’s a different set-up..bottom-line there’s a rain chance at any time Sat..but think most likely mid-morning to early afternoon. Outside of early AM storm, Sunday looks ok…tho hot and humid.

#FastFriday weather: rain moving in from the west this morning. Weakening on approach. Expect arrival between 9-10am, exiting noon-1pm. Rest of day good. Will post weekend forecast later, but little has changed from previous (Sat wet, Sun ok) #Indy500

Day 3 #Indy500 practice weather: cool, sunny, less windy. Last day with no rain concerns. Fri may see passing storm first half of track window (12-3)…Sat still looks active with rain threat much of day…Sun early shower but remainder of day tracking dry for now #IndyCar

Day 2 #Indy500 practice forecast: front moved through overnight, so cooler with a wind shift to northwest today. Thu dry. Rain chances return Fri and temps heat up moving into weekend. Sat looks like the most active day for storms. Sun better, but still a little early to lock that in.

Day 1 #Indy500 practice weather: Mostly sunny. Winds start from south but shift to more southwest and get gusty late. Wind graphic depicts the southwesterly wind. Rain overnight. Wed-Thu still dry. Fri-Sun chance rain each day, but timing continues to shift and is still uncertain at this point.

Initial #Indy500 practice/quals forecast: Tue looks good..then rain overnight..so possible drying needed Wed AM, but rest of day is dry. Thu dry. Fri and beyond almost certain to change this far out…but long-range suggests rain chances are late Fri/early Sat and then Sun PM…for now

Today’s #IndyGP forecast: morning clouds then mostly sun. Outside chance for an isolated shower late afternoon/early evening…but that appears most likely over northern portions of Indiana. Winds out of the southwest and gusty at times. #IndyCar

Updated #IndyGP forecast: some lingering showers possible Fri morning..followed by a dry period mid-morning..then rain chances return by Fri afternoon and increase the later we move through the day/evening. Most activity should exit by early Sat morning. Bumped Sat high temp to low-70s #IndyCar

#IndyGP forecast: temps on cool side…chance for showers on Friday…timing looks to be evening, but still a little too early to say with certainty…Sat dry for now #IndyCar

LATEST RADAR — As of 10:00 local time, Miami finds itself between shower systems. The next approaching cluster of showers is approximately 150km west-southwest of the circuit and is progressing around 60km/hr, so may arrive around 12:30–13:00 local time. #F1 | #MiamiGP 🇺🇸

#Indy500 open test forecast: two rounds of storms coming, but timing is overnight/early AM..so rain-free sessions, but some track drying will likely need to be done each morning. Cool and windy.

No major updates to the GP of Long Beach forecast. Friday the windiest day. Saturday the warmest day. May see some lingering marine layer clouds early Friday morning before burning off…then some upper level-based cloud cover moves in over the weekend. #IndyCar

Gorgeous preview today

Early look at weather for GP of Long Beach…generally sunny…a few clouds over weekend…low to mid 70s #IndyCar

Raceday conditions for #IndyCar today: southeast winds…gusty this morning around 20 mph…but should taper off as we get to midday and beyond. Race temps in mid-60s.

Today’s conditions at Barber Motorsports Park: colder/drier air has moved in overnight following yesterday’s cold front. Dewpoint temps (an indicator of how much moisture is in the air) have fallen from near 60 yesterday into the 30s this morning (very dry). Winds settle down later today. #IndyCar

Barber forecast update: no major changes…warmest day Fri…then cold front…slight chance a brief light shower survives along that front as it moves in, so might feel a few drops if out and about in B’ham Fri night…but all track sessions dry. Cooler temps Sat-Sun. #IndyCar

Early look at #IndyCar GP of Alabama weather: warm Friday…cold front overnight…then cooler/drier air moves in behind front on Saturday into Sunday. No rain expected (too dry).

BRAZILIAN GRAND PRIX — WEEKEND WEATHER FORECAST Hot and humid. Partly to mostly cloudy with a moderate to high risk of scattered hit-or-miss thundery showers each afternoon; some showers could be intense. www.meteomotorsport.... #MotoGP | #BrazilianGP 🇧🇷

Today’s weather story will be winds for #IndyCar: they start out of the south this morning..will shift to southwest…then once they get to northwest that’s the sign peak winds will be arriving. Latest guidance suggests 2-3 pm. Temps plummet overnight, 30s by Monday morning.

Saturday conditions at GP of Arlington…gusty winds the only weather element of note

Latest GP Arlington forecast: Fri/Sat good. There is a strong cold front which will dip into TX on Sunday..behind the front, gusty north winds will usher in colder air. Timing for now looks like 3-4 pm…which would place peak wind gusts post-race. Any precip should be east of Dallas.

First look at GP Arlington forecast: storms move through Tue/Wed..then clearing through weekend. Temps upper-70s warming to mid-80s. Winds will be picking up Sat..and depending on timing of next system..may even be higher on Sunday..something to keep an eye on through the week #IndyCar

Raceday weather for Phoenix: expect temps a few degrees warmer than Friday. Winds were mostly out of west today….they switch up overnight and should be blowing out of the east by green flag on Saturday.
