Daily update- Tuesday, April 5, 2016

NWPAC outlook, 05 APR

A spring storm system pulls away from the north region, leaving behind warm temperatures, as the warm air stays locked in throughout the central region. More heat is on tap in the south, while the tropics heats up as well and forecasts hint of the first activity of the season. 

NORTH

The latest spring storm system is moving to the east, well offshore of Japan. The associated frontal system extends back to the southwest over the Ryuku Islands. Moisture is streaming in from the west as another weak system gets set to form over eastern China later tonight and slide offshore towards southern Japan tomorrow. Skies will be cloudy in the southern and eastern portions of the region, while locations to the north and west will see lots of sunshine.

CENTRAL

Clouds and moisture will prevail over the northern third of the central region today, as a weak storm system develops in the evening and overnight hours. Cloudy and foggy conditions will develop over southeastern China as this system develops.  The remainder of the region will see warm afternoon highs with lots of sunshine and just a few scattered clouds.

 SOUTH

More heat is on tap for the south region, as the days get longer and the warm sunshine gets more time to heat things up. The easterly flow is combining with a wet southwesterly flow across Indochina, and is trucking in a good deal of moisture across the Philippines, so some scattered showers are possible throughout the archipelago today, especially in the southern two-thirds of the nation. Singapore and Malaysia could also see some scattered thunderstorms at the peak of afternoon heating. The remainder of the region will stay hot and dry with just a few scattered clouds.

 TROPICS 

The tropics are heating up as well, in more ways than one, as longer exposure to the direct sunshine heats up the ocean and the atmosphere across the region. The G.F.S. (Global Forecasting System) computer weather models have been persistently showing the development of a weak area of low pressure later this week in western Micronesia, which will drift west-northwestward towards the Philippines. This feature may be taking shape in the form of a concentrated area of convergence along the I.T.C.Z. (Inter-Tropical Convergence Zone) in eastern Micronesia, where clouds and thunderstorms will be scattered about this afternoon. The Marianas and Wake Island could see a few showers as well as a continental air mass impacts both locations. The remainder of the region will see plenty of sunshine and just a few scattered clouds.

Have a terrific Tuesday!
