Yes it was chilly - officially

Phew it was cold this morning.

The temperature fell to just 8.3 degrees at 4am, the coldest morning in Katherine since September last year.

The temperature didn’t break double digits until 7am.

The Bureau of Meteorology was a little off the mark with its prediction of a low of 11 degrees.

Which is the same forecast for tomorrow morning.

Weather experts says a strong high pressure system centred to the south of Australia has caused a pulse of cool and dry air to spread north into the nation's tropics.

And they were complaining in Darwin yesterday when the overnight May temperature dipped below 20 degrees for the first time in three years.

Katherine is expected to reach a maximum of 29 degrees today.

History tells us July is the coldest dry season month of the year in Katherine.

The long-term average of minimum temperatures in Katherine is 17.5 degrees.

Still we are are still short of the record May low of 5.5 degrees recorded in 1991.
