Daily update- Wednesday, March 9, 2016

NWPAC outlook, 09 MAR

Winter finally returns to the north region and begins to move into the central region as well. No such luck for the south region as the heat continues, and the tropics stay quiet, but heat up as well. 

NORTH

There are lots of pretty blue and red ribbons stretched across the surface map today, indicators of a very complex series of weather events taking place across the entirety of eastern Asia. The gist of it all is that colder air is moving southeastward across the continent, bringing a taste of winter to many locations as we get closer to the vernal equinox. One storm system is exiting the region to the northeast, as a double system moves over portions of northern Japan. An additional storm system is moving out of east-central China, riding along the cold air boundary stretched over the continent, and will slide across Korea and Japan over the next 24-48 hours. Temperatures have dropped significantly over the past 24 hours, but this drop will be short-lived in the north region, as the increasing sunshine warms the air mass rather quickly, returning the region to above-average temperatures by the end of the week.

CENTRAL

The central region will also see a significant drop in temperatures through the day, as the colder air mass pushes into the region. It will still be a pretty warm day across southeastern sections of the region, but temperatures will drop in the evening and overnight hours in these locations. Clouds, fog, and rain will affect parts of southeastern China and Taiwan, and Iwo To will see a rainy day as the first of a series of frontal systems moves away from the area. The remainder of the region will see just some scattered clouds and warm temperatures.

SOUTH

Brutally hot conditions are once again in store for portions of interior Indochina, as the sunshine bears down on the area through mostly clear skies. A surface trough is stretched out across the northern portions of the Philippines, and a few showers or thundershowers could erupt along this weak boundary. Singapore will also see a good chance for thunderstorms this afternoon as the ample moisture gets a lift from the intense sun.

TROPICS 

The tropics are devoid of any kind of organized activity right now, as the I.T.C.Z. (Inter-Tropical Convergence Zone) remains inactive and suppressed far to the south in the region. A bit of convergent energy can be found in scattered doses throughout the zone, bringing a chance of scattered showers and an occasional thunderstorm to parts of Micronesia and the Marshall Islands. Continental energy continues to affect Wake Island and the Marianas, with cooler temperatures and a few showers near Guam.

Have a wonderful Wednesday!
