Lucknow, May 14 -- Day and night temperatures are likely to rise by 2 to 4deg C in many parts of the state over the next five days, the Met has said in its forecast for the remainder of the week. Meanwhile, Banda remained the hottest city in the country, sizzling at 44.2deg C . Due to the increase in maximum temperatures, sporadic heatwaves were likely to start in eastern parts of the state from Wednesday. As per the warning, they are likely to spread to western UP by May 15 and continue till May 20, said Atul Kumar Singh, a senior scientist at Lucknow meteorological office. However, due to possible drizzle/light rain in the Terai areas of the state from May 16, the heatwave is likely to see a fall and may get restricted to only southern and adjoining central parts of the state then. Heatwave conditions are also likely to develop at some places in the state capital on May 16 and 17. Overall, the state was likely to see dry weather, the Met office said. Strong surface winds (of speeds up to 20-30 kmph) are very likely during daytime. Meanwhile, there was no respite in other cities as well.
