​The weather looks like it will be ideal for INDYCAR at the IMS road course this weekend. During setup on Thursday, there is a chance of showers as a cold front moves through the area, but by the time on-track action starts on Friday, the conditions will be dry and mostly sunny. The weather pattern is expected to have a low pressure system on the East Coast, with a large high pressure ridge over the Plains, putting Indiana in a dry north to northwest flow. Temperatures will be cool in the morning, with lows in the 40s. Friday will have a bit of a breeze, with a north wind at 10 to 15 mph keeping high temperatures in the 60s. Saturday will be a little warmer, reaching into the mid 70s.

The weather pattern has shifted quite a bit since my Monday forecast. The approach of a cold front has slowed considerably, bringing rain to the track on Saturday. 

Today, most of the on-track activity should be completed on time, but there is a chance of showers and thunderstorms late in the day. It will be mainly after 4 pm when showers and storms will be in the area. Storms will continue through much of the overnight hours, with heavy rain at times, and rain amounts of a half to one inch are possible. On Saturday, showers will be scattered, with on/off rain through the morning, then a line of showers and thunderstorms is expected to move through in the afternoon when the cold front moves through. This will likely cause on track activity to be delayed or canceled.

Behind the cold front, Sunday's weather looks great, with pleasant temperatures and low humidity, and abundant sunshine.

We've got some interesting weather on deck for the Miami Grand Prix as Spring time is in full swing. High humidity is expected and increases as the weekend goes on. A Low pressure system will be moving toward the region and increasing rainfall chances through Sunday as it converges with the warm, moist southeasterly winds. These storms would be scattered and at their peak in the afternoons as the sea breeze picks up.

Winds could get gusty if there are storms in the area, so teams must be prepared for multiple different scenarios this weekend. I will be posting radar updates for race day as storms could play a major factor in the outcome of this one. Temperatures will be quite warm too so hydration should be taken into account as well. We should be in for a good one! See metric graphic below...

A cold front is expected to move through the Southeast U.S. on Friday, which will bring a good chance of showers and thunderstorms to Barber Motorsports Park. Details are uncertain this far out regarding timing, intensity, and coverage of storms, but if you're going to be at the track on Friday, be prepared with rain gear and a plan to find  shelter when thunderstorms approach. Once the cold front pushes through, drier and cooler air will follow, and the rest of the event looks like it will have beautiful weather, with comfortable temperatures and humidity under sunny skies.

Nothing too crazy is in store for the Saudi Arabian Grand Prix as a loose High pressure gradient will be laid over the area through the weekend. We can expect cool mornings and hot afternoons with low humidity, so by night fall we should have pleasant conditions for drivers. Wind speeds will be low all weekend as well so sand on the track and hazy conditions will likely not be a threat. Drivers will get a respite from dealing with volatile weather conditions for these Middle East races. See metric graphic below...

We have some pretty seasonal weather for the Bahrain Grand Prix as it is going to be hot and humid out there. Gusty winds in the afternoons as the sea breeze sets in, but should be calm by the night time hours of race day. A Low pressure system is moving through Friday that will also kick wind speeds up a bit but dies back down for Saturday's session. Sunday will be like most years' past with little consequence from the weather outside of having a warm ambient temperature. We will get back to some more volatile weather when we get going with our Europe races. See metric graphic below:

A beautiful weekend is on tap for IMSA and INDYCAR at Long Beach. The main impact will be morning fog, as a southerly wind from the ocean will bring the marine layer inland each morning. With daytime heating, the fog will dissipate, likely by 10 AM, but it could impact some of the morning sessions. Temperatures will be pleasant, if a bit cool, reaching the upper 60s to lower 70s each afternoon.

A chilly weekend with some rain at the back end is in store for the Japanese Grand Prix. A Low pressure system will be moving through the region with a cold front bringing a long squall line that is slated to pass over the site Sunday morning. Leading up to this frontal passage, gusty winds will be present Friday afternoon with much calmer conditions for Saturday. Clouds begin to set in Saturday afternoon ahead of the storms which could pose a challenge for keeping tires warm.

Expect severe storms Sunday morning and possibly into the afternoon as the squall line makes its way through the area. Even if the storms pass before race time, the track will be wet and low temp which poses a challenge for drivers' strategies. I will monitor and update the timing of the storms for race day.
