Weekend update- April 30-May 1, 2016

NWPAC outlook 30 APR-01 MAY

The seasons are clashing over the north region this weekend with record heat AND snow. The central region continues to deal with the onset of the East Asian Monsoon, but gets a bit of a break this weekend. The south gets some relief from the record-setting heat as moisture and heat increase across the tropics.

NORTH

The seasons are meeting over the north region where only 1045 km (649 mi) separates record setting summer heat in the mid 30’s, from snowfall and winter’s chill in the single digits. Parts of interior northern and central China will see record-setting, or near it, daytime highs through the weekend. While to the north over extreme northern China and Mongolia, a surge of cold Siberian air will bring in much cooler temperatures and a chance for snow in the northernmost locales. Aside from unsettled weather in locations far to the north, the remainder of the region will see lots of very warm sunshine with an occasional passing cloud.

CENTRAL

The latest frontal system to pass through the central region has pulled up stationary just to the south, but is far enough away to allow for some clearing of the incessant cloud-cover and rainfall associated with the seasonal monsoon that is getting underway. Taipei will be the lone exception, as lingering moisture gets a lift in the mountainous terrain to squeeze out some showers. An impulse of energy moving through the region will bring some scattered thunderstorms to southern China and northern Vietnam on Saturday and to the coastal of southeastern China on Sunday. Temperatures will be seasonably warm across the region this weekend, with rainy areas seeing a bit of a dip as clouds block out the ever-intensifying sunshine.

SOUTH

An increase of moisture from the tropics is bringing much-needed relief from the heat to parts of the south region this weekend. Energy from a weak system passing to the north will propagate southward into interior portions of the Southeast Asian peninsula and bring about a good chance for scattered thunderstorms at the peak of midday heating. A stationary cold front is stalled out over the northern Philippines, and will combine with tropical moisture moving through to fire off some occasionally heavy thunderstorms in some spots. Plentiful tropical moisture over areas to the south will also help fuel afternoon thunderstorms, from the southern Philippines all the way west to Malaysia.

TROPICS

The I.T.C.Z. (Inter-Tropical Convergence Zone) appears to be ramping up slowly, almost methodically, as we advance through the spring “tropic-warming” months. The region of warmest S.S.T.’s (Sea-Surface Temperatures) continue to spread and grow region-wide, as the sunshine really heats things up without much cloud-cover to help moderate the beaming intensity.

NWPAC SST’s 30, APR

A few areas to note are located within the tropics this weekend. From west to east, we first find a wave, and plume of moisture, drifting across the Philippines, interacting with a stalled continental frontal system over the northernmost island of Luzon. There’s no chance for development of this system, but it could launch a few strong thunderstorms over northern parts of the archipelago, especially today. Part of this wave, or trough, extends back to the southeast and will help provide some energy for thunderstorms to develop in the southern part of the nation as well. As we travel east, we find another ripple of energy located south of Chuuk Island in Micronesia. The satellite looks impressive, but forecast models do nothing with this system, other than slide it through the region as a weak tropical wave. The final area is a wave of energy passing from the Marshall Islands into eastern Micronesia. It’s a rather compact area of disturbed weather, and although it shows no signs of development, it will bring plenty of showers and thunderstorms to Micronesia over the coming days.

Have a wonderful weekend!
