Moist Southwesterly winds blowing from the Atlantic Ocean are established and their position have remained stationary for most part of this week, for today, they have largely maintained their position at Lat. 14.5oN in the Western sector and also at Lat. 13.3oN 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 the Northeastern state (Jigawa), in the Northwest over Zamfara/Kebbi states, over Adamawa/Mambilla plateau and spread across the border into Cameroon republic; convective cells also formed over the Central states especially over Abuja/Nasarawa/Niger/Kwara/Kogi states, over parts of the Southwest, Southeast and across places in the South-South states. Thunderstorms are likely to affected parts of the Central and Northwestern states including Abuja this evening/night.
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. 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.
