The forecast has improved considerably from last week and even earlier this week, however BOM statistics don't lie and as far as I can tell there was actually very little rain in the lead up to the 3 ring circus. Obviously being winter and all there was less evaporation and drying action too but there were no rain at all recorded for 6 days in the lead up, then only 0.2mm on the Friday and 1.4 mm on the Sunday. So comparisons to the track conditions at the 3 ring circus may not be the best to gauge the condition for this Sunday.
On the other hand, in the week leading up the fling last year a total 10.4 mm of rain fell on the Mon, Tues, Wed then a little extra 0.4mm to 9am on Friday before dry conditions for the rest of Friday and on the Saturday and Sunday.
Currently this year we're sitting at 3.2mm to 9am on Wednesday and 1.8mm to 9am on Thursday... there's another 5-10mm forecast for today and 1-5mm forecast for tomorrow :rain:. If we all cross our fingers and hope for the lower end of those ranges then we'll end up with very similar rainfall to last year and the track last year was primarily dry with a few patches of soft stuff in the last stage on the single track :Banane35:.
The differences being, it looks like the track will get one less day to dry out this year as compared to last year. The preceding weeks have been drier this year.
