After cooler days experienced since Wednesday helped by scattered rains, the scorching summer heat is back this weekend with the cold front starting to diffuse and allow temperatures to rise.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported Saturday that hotter days are to come.

In its 5 a.m. weather bulletin, the diffused tail-end of a cold front only prevails in Northern and Central Luzon.

The weather condition is expected to bring cloudy skies with scattered rainshowers.

PAGASA weather forecaster Joel Jesusa explained that a cold front occurs when a cold air mass pushes into a warmer air mass causing gusty winds, a drop in temperature, and rains.

“Cold air is so dense that it is able to quickly push a warm air mass ahead of it,” said Jesusa.

Last Friday, the cold front caused rains in some parts of Metro Manila, and provinces in Luzon, ending two rainless-months in the country due to the El Niño phenomenon.

“We will again experience increase in temperatures when the cold front will totally disperse,” Jesusa said.

But as of this weekend, he said the diffused cold front will bring mostly cloudy skies with scattered rainshowers in Northern Luzon and Mindanao.

The rest of the country will be partly cloudy to at times cloudy with isolated rainshowers or thunderstorms.

However, in the coming week, the maximum air temperature is expected to reach 34 to 36 degrees Celsius, while the minimum temperature will be from 23 to 25 degrees Celsius, the weather bulletin stated.

The minimum temperature registered in Metro Manila at 6 a.m. yesterday was 24.6 degrees Celsius, slightly up from 24.1 degrees Celsius last Friday.

The highest temperature recorded in the National Capital Region last Friday was 32.4 degrees Celsius.

The weather bureau so far recorded the hottest day of the year in Metro Manila last March 6 with a temperature of 35.8 degrees Celsius.

PAGASA said that the temperature in the country is expected to reach 37 degrees Celsius due to persisting El Niño.

The weather phenomenon is the warming of sea surface water at the Pacific Ocean that causes below normal rainfall.

PAGASA also said moderate to strong winds blowing from the northeast to east will prevail over Luzon, Visayas, and Eastern Mindanao and the coastal
waters along these areas will be moderate to rough.

Elsewhere, winds will be light to moderate blowing from the northeast with slight to moderate seas.
