Delhi: Light showers bring relief from high humidity, widespread rain expected on July 11
Met officials are expecting a widespread rain on July 11. They claimed that a system could develop over NCR and adjoining areas and that could pave the way for more moisture laden winds from the sea to gush in.delhi Updated: Jul 06, 2017 23:23 IST
A smart shower that lasted for a few minutes lashed Delhi on Thursday evening raising hopes of a bountiful rain.
Met officials, however, claimed that a widespread rain and thundershower could hit Delhi only on July 11.
Till then Delhites would have to bear with some muggy weather as the temperature is expected to hover above 37 degrees Celsius and the relative humidity would also be high.
“While the Safdarjung observatory registered around 0.1 mm of rain till 8:30 pm, the observatory at Palam received around 5.6 mm of rain. The rain was localised and restricted to isolated places,” said a senior official of the regional weather forecast department.
Such localised showers are normal during the monsoon season. The moisture content of the air is high and a little heat gives rise to convective currents which in turn triggers rains in some places.
“But for widespread and heavy rain we need some bigger systems such as a trough or a cyclonic circulation, which could churn out rain from the rain bearing clouds,” said the official.

“This could trigger some widespread rainfall in Delhi NCR region on July 11 and July 12. But till them situations would remain almost the same as Delhites experienced on Wednesday with a cloudy sky, a muggy weather and chances of a light rain in isolated patches in the evening,” said the official.
Even though the temperature is hovering in the normal range, high relative humidity is making the weather muggy and sweaty. On Wednesday the day temperature was 35.8 degrees Celsius which was less than the normal.
“It is because even though the temperature has not shop up, the relative humidity has increased. This in turn has forced the Heat Index to shoot up,” said a weather official.
Heat Index is calculated taking into consideration both the temperature and the humidity levels. Hence it gives a better measure of how hot or cold it really feels instead of measuring the temperature alone. The higher the heat index, the hotter we feel.
