Moist Southwesterly winds blowing from the Atlantic Ocean are established and their position remained unchanged for the past three days; for today, they have largely maintained their position at Lat. 14.5oN in the Western sector and also remained at Lat. 13.5oN in the Eastern sector, within Niger and Chad republics respectively. The South Atlantic anticyclone (also known as St. Helena high pressure cell) located in the Southern Hemisphere is weakened and continue to reduce in strength whilst the extent of it's ridge of high pressure into West Africa is diminished; hence moisture influx into far northern parts of Nigeria is decreased. The satellite imagery of today at 1500GMT shows convective cells developing over Mambilla plateau and extends into parts of the Southeast and spread across the border into Cameroon republic; convective cells also formed over the Central states especially over Jos/Bauchi high grounds, over parts of the Southwest and across places in the South-South states. Thunderstorms affected parts of the Central states including Abuja this afternoon/evening
Hot and clear to partly cloudy conditions will affect most parts of the Northern states, however, isolated thunderstorms are likely to affect parts of the Northwest in the afternoon/evening. Sunny and partly cloudy to cloudy conditions will prevail in the Central states while isolated thunderstorms are expected to affect places especially in the high ground areas during the evening/night period. The Southern parts will be mainly cloudy with chances of rain showers in the morning; however, thunderstorms are expected to affect parts of the Southwest while thunder with rains are likely to affect areas in the Southeast and Coastal states during the afternoon/evening periods.
