How much rainfall is left in the wet season for the NT and Kimberly?

We are getting to that time of year, where the dry season is knocking on the door over the tropics. Some drier air has already moved into a good portion of the upper Top End and Kimberly with a great reduction in the amount of showers and storms in recent weeks.

The wet weather is expected to hang on for another week or so over the Arnhem Land and Carpentaria districts which is quite normal for this time of year, with the wet season continuing until June, spurred on by onshore southeasterly winds.

Those same southeasterly winds actually bring the dry surges into the Top End and eventually clear the humidity and wet season through Indonesia and back north of the Equator come the end of May into June.

I fully expect a couple more showers and storms lurking through the far northern Daly district and the Tiwi Islands over the next week, with the bulk of the rainfall now concentrating on areas east of Maningrida towards Gove and Nulunbuy.

These areas out east could see 30-70mm of rainfall over the next week and additional falls next week with lurking moisture and onshore winds.

The weather will trend drier as we go through May, with rainfall contracting eastwards.

No sign for a large clean out of humidity yet for the Top End and Darwin. The heat indices have come down somewhat in recent days, but the true dry air is still about one month away.

There will be a little tease of dry season come probably Thursday or Friday following an upper trough through the region.

But those lovely brown tones that indicate the dry get shunted back west by the end of this month so a little more sticky (not build up) for the beginning of May.

We need a large front to come in and clear everything out and the longer term charts don't have that occurring just yet.
