NWPAC outlook, 22 MAR

NWPAC outlook, 22 MAR

Cooler air stays locked in for the north region, as the central region holds steady ahead of a cool surge. There are hints of some relief in sight for the central region, while the tropics remain quiet. 

NORTH

Temperatures across the north region are seasonably cool today, as high pressure settles into the region. Another frontal system associated with a weak reinforcing wave of air is moving slowly through eastern Russia, Korea, and northern China, with the western edge of the air mass staying put over Mongolia. Mid and upper-level clouds associated with the jet stream are passing over a good portion of mainland China, bringing considerable cloudiness to these areas. The remainder of the region will see lots of sunshine with just a few scattered clouds.

Ulaanbaatar 7 (45) -8 (18) Partly Cloudy
Vladivostok 8 (46) -5 (23) Partly Cloudy
Beijing 14 (57) 3 (37) Cloudy

Tokyo 15 (59) 7 (45) Fair
Xi’an 14 (57) 9 (48) Cloudy
Shanghai 16 (61) 10 (50) Cloudy

 

CENTRAL

Temperatures across the central region are holding steady as the latest frontal systems moves away from the region to the east. Another surge of cooler air is expected to come down over the next 48 hours, helping to cool things off a bit in the region. Lingering moisture, along with some upper-level energy from the jet stream, will help fire off some rain and a few scattered thunderstorms over the southern one-third of China and northern Vietnam. Everyone else should see a pretty nice day with a mix of clouds and sun.

 SOUTH

Intense heat remains over the south region today, especially over inland locales of the Southeast Asian peninsula, and the Philippines. There are hints of some relief coming down from the north starting on Thursday, with a surge of cooler air expected to make it all the way into northern Vietnam and the Philippines in time for the Easter weekend. The graphic below is from the GFS computer model, and I have highlighted the farthest extent of the surge on Sunday.

For today, however, the heat is on for most locations under partly cloudy skies. Singapore and Malaysia will likely see their daily dose of thunderstorms at the peak of afternoon heating as ample moisture slides through the area and gets a lift from the intense sunshine.

Davao City 34 (93) 23 (73) Partly Cloudy
Brunei 31 (88) 26 (79) Partly Cloudy
Singapore 32 (90) 27 (81) Thunderstorms

 

 TROPICS 

Unlike last year, the tropics are dead quiet; however, a slow shift in moisture content through the region is evident as the continental air masses stay out of the more southeasterly parts of the region. A few weak areas of convergence are located along the I.T.C.Z. (Inter-Tropical Convergence Zone) affecting parts of Micronesia and the Marshall Islands. To the north, drier continental air continues to impact the Marianas and Wake Island, with cooler temperatures and a few more clouds.

Have a tubular Tuesday!
