THREE MONTH OUTLOOK FOR JUN/JUL/AUG:

NCEP's Depiction of the Global Sea Surface Temperature Evolution

The average Indian Ocean Dipole Mode Index for the past week is 0.32 (0.62 standard deviations), the average Southern Oscillation Index (SOI) for the past 90 days is 3.92, the average SOI for the past 30 days is 0.1, and the latest recorded bimonthly Multivariate ENSO Index (MEI) is -0.79. The expected MEI, adjusted by the Indian Ocean Dipole Mode Index and also by recent values of the SOI, for APR/MAY is 0.06. Such a value of MEI indicates a sea surface temperature distribution that corresponds to neither a La Niña nor an El Niño. This suggests:

RAINFALL: There is an enhanced chance that average JUN/JUL/AUG total rainfall will be close to normal in the WIMMERA and EAST GIPPSLAND Districts, but there is little indication as to whether rainfall will be below, near or above normal in other Victorian Districts.

OVERNIGHT TEMPERATURES: There is an enhanced chance that average JUN/JUL/AUG overnight temperatures will be close to normal in the MALLEE, NORTH CENTRAL, NORTHEAST, WEST GIPPSLAND and WESTERN Districts, 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 JUN/JUL/AUG daytime temperatures will be close to normal in the WIMMERA and WESTERN Districts, but there is little indication as to whether daytime temperatures will be below, near or above normal in other Victorian Districts.
