Mohali: Heavy rains and thunderstorm lashed Mohali tonight on the eve of the blockbuster World Cup semi-final clash between arch-rivals India and Pakistan at the Punjab Cricket Association stadium tomorrow.

The Meteorological Department has forecasted a partly cloudy sky to prevail in this region with a little chance of light rain by the evening tomorrow.

"The local forecast for tomorrow is partly cloudy sky with less chance of rain," an official of the Chandigarh-based MeT Department told PTI.

Earlier in the day, Mohali and Chandigarh witnessed bright sunshine. Dust storm with drizzle had occurred yesterday.

According to the MeT's area forecast, including that of entire Punjab, there could be dust storm or thunderstorm with light rain at a few places in the state tomorrow.

The MeT said that currently western disturbance is prevailing over Jammu and Kashmir and its neighbourhood while Rajasthan and its neighbourhood has been experiencing an Upper Air Cyclonic Circulation.

The maximum temperature at Mohali and Chandigarh is hovering in the range of 30-32 degrees Celsius.

The maximum relative humidity today was around 68 per cent and the minimum relative humidity was likely to be around 39 per cent.

According to the Mohali pitch curator Daljit Singh, ball is likely to seam around under the flood lights.

What if it rains tomorrow?

Even though the Met department says it is unlikely, if tomorrow's match is rained out, then there is a reserve day - on Thursday when the match can be played. But, if Thursday is also washed out by rain, then the rule states, "If following a tie, weather conditions prevent the one over eliminator from being completed, or if the match is a no result, then the team that finished in the higher position in the Group stage shall proceed to the final."

So, if the weather gods are really unkind, it will be heartbreak for India, and Pakistan will make the finals.
