By: Harris Cooley Cloudy and rainy weather will be moving through the region Friday and Saturday as Low pressure lays over the site. Westerly winds will bring moisture in off the coast and keep cloud coverage in the forecast all weekend. This moisture and cloud coverage will cause grip issues in a couple ways as the track will surely be wet as the rain moves through, but cloud coverage will also cause track temps to be low as well. High pressure rolls in by Sunday clearing most of the rain chances out and giving teams' a bit less of a headache. Spa shall not disappoint as usual. See the metric graphic pasted below...
By Doug Schneider Click images to enlarge The weather continues to look great in Toronto for INDYCAR weekend. As I mentioned in my initial forecast post, a cold front will move through the area on Saturday night and Sunday morning. It is possible that a few showers near the front could produce light rain early Sunday morning, likely before any on track activities begin. No impacts are expected if rain does occur.
By Doug Schneider Click on images to enlarge Beautiful weather is expected this weekend for the Honda Indy Toronto.
High pressure will be over the Great Lakes region at the start of the event on Friday, and gradually drift east across southern Ontario and New York through Saturday. A cold front will approach Toronto from the north on Saturday night, but any showers near the front are expected to dissipate before the front gets to Toronto. It will cross the city on Sunday, but the only change in the weather will be a little more cloud cover, and winds that will shift to a north direction. By: Harris Cooley High pressure will be sitting over the region keeping rain chances low throughout the weekend. A loose pressure gradient will lay over the site catering to low wind speeds as well. Temps will be high bringing track temps up and forcing teams to strategize around the track degradation. This will be the main threat outside of drivers remaining hydrated through the heat - no chances for rain as of now with low winds should make for a competitive race. See the metric graphic below...
By Doug Schneider Dry weather is likely for the Hy-Vee INDYCAR weekend at Iowa, but hot temperatures will be the main impact. The weather pattern is expected to change little through the weekend, with high pressure dominating much of the Great Plains. This should result in mostly sunny skies and a rain-free weekend. With temperatures reaching into the lower 90s on Saturday and Sunday, the heat Index may reach to near 100 degrees. If you're going to the Speedway, be prepared for the hot conditions by drinking plenty of water and taking frequent breaks in the shade.
By: Harris Cooley Tight pressure gradient will be laying over the region bringing moderate to gusty wind speeds this weekend. Scattered rain showers will be rolling in as well throughout the weekend as a result of the pressure profile. These showers will be fast-moving but impactful if they pass over the track. This is not unusual for this race so teams will likely be prepped for these conditions. See the metric graphic below...
By Doug Schneider Click on images to enlarge A low pressure system is still expected to track south of Belgium over the weekend, bringing rain to Spa mainly on Saturday night.
The first several hours of the race are expected to be nice, with clouds increasing through the day and pleasant temperatures. Showers are expected to spread in from the west late in the day or evening. Sunset at Spa is around 9:52 pm, and rain will likely start between 8 pm and 10 pm. During the evening hours, a few thunderstorms maybe possible in the area, and if a storm moves over the track, it could produce a brief heavy downpour. Otherwise, on/off rain of light to moderate intensity can be expected through the night. The showers will decrease in coverage by sunrise on Sunday, but could still be scattered in the area until around noon on Sunday. Sunday afternoon will have decreasing clouds and an increasing northwest wind. The total amount of rainfall during the race is expected to be between 12 and 25 mm, or between 0.5 and 1 inches. It would not be surprising if there was a period of the race that was red flagged due to the combination of rain and darkness, but I am confident that wet tires will be needed at the very least. By: Harris Cooley A Low pressure system north of the region will likely induce high moisture contents through the weekend here at the Austrian GP. Friday afternoon will be partly cloudy to begin the day with the chance of afternoon showers to begin popping up along the coast. Saturday looks to be mostly clear with cloud coverage increasing into the afternoon. Another Low pressure north of the site is expected to pass Sunday afternoon into the evening bringing rainy weather in its path. This is unlikely to affect the race, though teams should have their radars up to be sure.
Wind speeds stay low throughout the weekend as the pressure gradient stays mostly loose over the region. Warm temps and low cloud coverage could bring high track temps giving teams another factor to think about. This paired with the rain threats could make this a headache for team principals.
