Jeez, you'd think I would have learned to check the radar or even simply look out the window before making a big statement like, "the Wet is finished.... PS/- that arrow is not my 'home', I'm in Leanyer, so still looks promising......  |

PS/- that arrow is not my 'home', I'm in Leanyer, so still looks promising...... Nope....not a drop at my place, my mate Nikko got 2.9mm at Gunn Point and there was a bit of a 'Hector' downpour on the Tiwi Islands this afternoon. Bye bye wet season ! |

Bureau of Meteorology, Northern Territory @bom_NT Yay for the delightful early dry season 'no sweat' conditions in the Top End! Enjoy it while it lasts. Sticky conditions will develop especially for coastal areas as this arvo's humid sea breeze moves in. Another dry burst is due leading into the weekend.  |

Will it or won't it ? Reports of 40mm out at Jabiru in Kakadu National Park. Will it make it into Darwin tonight/tomorrow ? The last hurrah of the 2020-2021 'Wet'.    |

Another huge kick arse storm this arvo, dropped 27mm at the Airport in 30mins.....so how did I go at the Desierto de Leanyer otherwise known as Leanyer Heights ? Well on top of yesterdays 4.0mm, I scored 2.3mm. The storm today split off about a kilometer east of me and hammered the Airport. I was over at the local Bunnings Store ( an Aussie version of Home Depot ) and had like 20mm in 20 mins. The son said to me, "might be some at home......" Nope, SFA, keeping in with the rainfall since mid Feb. Some Palmerton stations ( 20-25klm south of me ) have had 2800mm rain this wet season....thats about a 1000mm more than the Darwin Northern Suburbs, of which I'm smack bang in the middle of. |

Had another small squall line blow through just after dark, another 6.7mm on top of the afternoon's 2.3mm. So 13mm in the two days at the end of April.....just about a pass mark for late in April. |

Preliminary figures for the Leanyer BOM rain guage 2020-2021 Wet Season ( still a day to go in April of course )
Mean - Median - 2020-2021
Oct - 68.6, 65.0, 147.4
Nov - 120.6, 109.6, 118.8
Dec - 295.2, 243.9, 377.8
Jan - 447.8, 452.0, 691.0
Feb - 380.0, 346.6, 375.0
Mar - 324.8, 294.4, 120.6
Apr - 101.6, 77.2, 102.6
Totals - Mean Average - 1738.6mm
Totals - Median - 1588.7mm
Totals - 2020-2021 - 1933.2mm.
So a definite 'pass' mark, being nearly 200mm above average and 350mm odd above the median. One can't but help being a little disappointed with the March totals in the Northern Suburbs, and even April, although average, promised so much but failed to deliver.
There are possibly umpteen meteorological reasons for this, but my take on it is that once the monsoon buggered off in Feb, the patterns reverted to 'build up' like conditions of convectional afternoon showers and storms, Gulf lines from the East etc, patterns that historically do not favour the Northern Suburbs, hence the 'Dome' theory so unbeloved of Northern Suburbanites kicked in and our 'Wet' went out with a whimper, despite the bangs of the last two nights.
But, yes indeed, happy to take a season 200mm above average, and way way better than the two previous seasons !
2019 -2020 = 1138.2mm
2018 -2019 = 1110.0mm

Darwin Airport 2020-2021 Wet Oct-April
Total = 1857.8mm
Mean = 1678.4mm
Median = 1548.7mm.
As with the Northern Suburbs, started well early, but the Monsoonal stuff buggered off in Feb, so finished with a whimper. That 35mm the other day saved April somewhat.
A pass mark, 180mm above average, particularly given the last two seasons.

The North West Cloudband may make an appearence in a week or so's time. Rare to impact Darwin in the dry season months, but has happened historically. More likely to deliver cold and rain to Central australia. "KEEPING AN EYE ON MOISTURE POOLING THROUGH THE ATMOSPHERE NEXT WEEK. With a low pressure system likely to bring some heavy rainfall and strong winds to southern WA next week, a lot of moisture well to the north and northwest of the system, could be dragged across northern Australia in a more mobile upper level pattern. This could bode well for inland areas to see not only an increase of cloud, but rainfall potential moving into early June. With the prevailing wind pattern turning northwest to northerly in the upper atmosphere, thanks to a broad upper trough and low pressure system over WA, this could open the door for moisture to stream south into the NT, QLD and northern SA. IF the upper level low/trough next week from WA can move east or northeast and run into this moisture profile, then there is some chance rainfall could break out over inland areas. Some modelling has already started to show that as an option. We need a trigger to lift that moisture into rainfall, rather than just high pressure keeping it as a cloudy mess over the inland with little rainfall. I am siding still with the solution that the low off WA will likely wash out into an open wave and pass through the southeast next week with showers, but there has been a softening of this idea since last night, so will continue to monitor and obviously my rainfall analysis will change according when confidence increases." Image - Precipitable water values - Monday May 31st 2021. It is some ways out so this is just one idea that is on the table and not an absolute.  "Rainfall numbers are starting to pick up at the end of the 16 days - but this will likely change as we track through the coming days. Again an idea that is on the table, not a forecast, more of a signal."  Source: Karl Lijnders. |
