THREE MONTH OUTLOOK FOR AUG/SEP/OCT:

NCEP's Depiction of the Global Sea Surface Temperature Evolution

The average Indian Ocean Dipole Mode Index for the past week is -0.62 (-1.19 standard deviations), the average Southern Oscillation Index (SOI) for the past 90 days is 5.74, the average SOI for the past 30 days (click here for a picture of recent trends) is 12.32, and the latest recorded bimonthly Multivariate ENSO Index (MEI) is -1.11. The expected MEI, adjusted by the Indian Ocean Dipole Mode Index and also by recent values of the SOI, for JUN/JUL is -1.06. Such a value of MEI indicates a sea surface temperature distribution that corresponds to a La Niña. This suggests:

RAINFALL: There is an enhanced chance that total AUG/SEP/OCT rainfall will be above normal in the MALLEE, WIMMERA, NORTHERN COUNTRY, NORTH CENTRAL, NORTHEAST, WEST GIPPSLAND, CENTRAL and WESTERN Districts, but there is little indication as to whether total AUG/SEP/OCT rainfall below, near or above normal in the other Victorian District, EAST GIPPSLAND.

OVERNIGHT TEMPERATURES: There is an enhanced chance that average AUG/SEP/OCT overnight temperatures will be above normal in the NORTHERN COUNTRY, NORTH CENTRAL and NORTHEAST Districts, there is a slightly enhanced chance that overnight temperatures will be above normal in the WIMMERA District, there is a very slightly enhanced chance that overnight temperatures will be above normal in the WESTERN District, but there is little indication as to whether overnight temperatures will be below, near or above normal in other Victorian Districts.

DAYTIME TEMPERATURES: There is an enhanced chance that average AUG/SEP/OCT daytime temperatures will be below normal in the MALLEE, WIMMERA, NORTHERN COUNTRY, NORTH CENTRAL, NORTHEAST and WEST GIPPSLAND Districts, there is a slightly enhanced chance that daytime temperatures will be below normal in the CENTRAL and WESTERN Districts, and there is a very slightly enhanced chance that daytime temperatures will be below normal in the other Victorian District, EAST GIPPSLAND.
