The first two days of the Wimbledon Championships featured unseasonable warmth with a good deal of sunshine.
High temperatures on Monday and Tuesday climbed to around 77 F (25 C). The normal high in London during this time of the year is near 21 C (70 F).
Tennis Channel analyst Justin Gimelstob stated, "The warmer weather translates to faster conditions due to lighter air and the ball moving through the air quicker."
"When the weather is warm, especially for long stretches, the courts get harder and the balls bounce higher creating a dynamic where the ball picks up speed upon contact with the court surface," according to Gimelstob.
A large area of high pressure remains centered west of the United Kingdom, forcing any stormy weather to the north and east of London through Wednesday.
It will be several degrees cooler on Wednesday, but still seasonably warm with partly sunny skies.
The area of high pressure will shift southward on Thursday as a storm system approaches from the west. Dry weather will prevail on Thursday, but rainfall is expected to arrive Thursday night.

This storm system will then continue to bring the threat for rain to the London area on Friday and Saturday. While the precipitation will not be continuous, any rainfall from Friday into Saturday could be enough to cause delays on the outside courts.
The weather looks to remain unsettled at times during the second week of play as a slow-moving storm system continues to spin over the region.
The greatest threat for rainfall during the second week of play appears to be during the second half of the week and could have an impact on the semi-finals and finals.
Even though the Centre Court roof will keep matches going through any adverse weather, this also creates a different environment for players.
Gimelstob noted "When the roof closes, Wimbledon becomes an indoor event with a completely controlled environment, no sun, nor wind which favors the more aggressive player."
Rounds of severe thunderstorms, including the potential for flooding rain and tornadoes, will continue to erupt over the central United States this week.
As the unofficial start to summer approaches this week, the longest stretch of warmth so far this year will surge into the northeastern United States.
Conditions will become favorable for tropical development over the Atlantic Ocean, in the vicinity of the southeastern United States toward the end of May into early June.
Showers and thunderstorms may strike during Corpus Christi events across Germany on Thursday.
Rain caused additional delays at the French Open on Monday, but dry weather is expected on Tuesday.
Researchers are considering a monumental feat to increase the annual rainfall across the arid desert regions of the United Arab Emirates which would involve constructing a large, man-made mountain.
