Moist Southwesterly winds blowing from the Atlantic Ocean are established and their position have now moved slowly Southwards, for today, they have moved their position to Lat. 14.3oN in the Western sector and also to Lat. 13.1oN 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 stagnant whilst the extent of it's ridge of high pressure into West Africa is relaxed; hence moisture influx into far northern parts of Nigeria is decreased.
The satellite imagery of today at 1500GMT shows convective cells developing over Northern Adamawa, over the Mambilla plateau and extends down to parts of the Southeast and spread across the border into Cameroon republic; convective cells also formed over the Central states especially over the high grounds, over parts of the Southwest and across the Coastal areas of some states in the South-South. Thunderstorms are likely to affect places in the Central states including parts of Abuja this evening/night.
Hot and clear to partly cloudy conditions will affect most parts of the Northern states. Partly cloudy to cloudy conditions will prevail in the Central states while 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 scattered rain showers at mid-morning; however, thunderstorms are expected to affect parts of the Southwest, Southeast and Coastal states during the afternoon/evening periods.
