It's not surprising there was a massive dry air surge these past few days, the ridge over the Bight was up to 1035 hPa. That's real dry season conditions, with temperatures ratcheting up and humidity dropping.

According to BOM there's a surge expected from the northern hemisphere and while there's also surge coming in from the south it's likely to activate a monsoon trough. Time will tell whether it'll manage to descend as far has here, although if it stays to our north it increases the chances of a tropical low forming.

Certainly not dry season conditions over the last 18 hours or so here in Palmerston.
After a few very balmy dry season type days the heavens opened yesterday afternoon with a quickfire 28mm in a gusty knockemdown type storm. Then at 2am this morning I was again woken by thunder before another very intense storm deposited a further 54mm.
82mm in the bucket this morning.... love it wink

Yesterday was different for sure. But no rain here during the day. There was a heavy shower around Berry Springs and I could see the storm moving further north from us at Noonamah. But we got it during the night, 44 mm.

Today was getting back closer to dry season conditions again. Next week a low is expected to form off the north coast and move south west staying well off shore. GFS has it intensifying dramatically in the Indian Ocean. But I think there's too much dry air surging up from the intense high pressures coming across the bottom of the continent for anything significant to develop. Still, you never know. Monica came through right at the end of April and brought a lot of rain with it.

Yeh I see good old Ernie has rapidly intensified to 2 going on a three so the one off our coast will need watching I reckon. Latest 4 day charts have it nearing the Tiwi Islands from the north and not moving real quick at all.
Meanwhile Darwin Airport now up to third wettest wet season shocked

To date, this year would have to be the best season I've seen for the past three to four years. Nothing like 2011, but that one was a doozy.

The spear grass up here is used as a 'tell tail' for the end of the wet, and right now, it is nice and high and starting to dry out. We had a few scuds pass over us last week and this has already started to knock some of the grass over.
The river crossings are all still up, so it's still going to be a month or maybe more till we're able to consider driving too far out of town. Until that time, I'm pretty happy with being able to catch a barra or two from the comfort of my 4wd.

There's two Spear Grass times, the earlier one is the Yirridja, and the later the Duwa. Then the dry season moves in.

Some great rain falling over Arnhem Land over the last day or so. I have an un-named river in my back yard, and another in the front yard. Gotta love this time of the year.

Darwin's temps in the high teens this afternoon are deadset paranormal. How on Earth is this even possible at this time of year?

According to BOM there was strong dry south east wind blowing into the system. The heavy rain falling through it caused evaporative cooling. Basically a huge natural evaporative airconditioner. It's a very rare occurrence.

Just saw yesterdays temps in Darwin, cripes 18C mid arvo in April would be chilly even here in southern QLD! Woolen socks and uggies in high demand I spose?
Will be doing my 2-3 yearly NT trip for a week in May, should be plenty of water out on the floodplains after the big wet, can't wait! Hopefully warms up a bit by then too poke

EC has a low just north east of the Top End late next week and moving westwards. GFS has a weaker low further north. No surge from the north so may not come to anything. BOM ramps the temps up between now and then.

Both EC and GFS are indicating the wet season isn't over just yet. Mid next week they have a low in the Arafura Sea moving westwards. This is from the Windytv site.

GFS has it crossing the central Arnhem Land coast and moving over the north western Top End.



EC keeps it off the north coast and north of the Kimberley.

GFS has shifted the coastal crossing to the north west of the Top End, closer to the track of the last tropical low. EC still has it north of the continent, bit closer to Timor. Current wind shear through the area is about 15 - 20 kts and, looking forward, possibly reducing. But there seems to be a lot of dry air around.
