Katherine is in for a scorcher of a week.
The only good news is that the Bureau of Meteorology today downgraded our maximum expected temperature on Thursday from 43 degrees to 42.
The bureau says Katherine can expect:
Today (Monday) – 40 degrees.
Tomorrow (Tuesday) – 41 degrees.
Wednesday – 41 degrees.
Thursday – 42 degrees.
Friday – 41 degrees.
Saturday – 40 degrees.
Sunday – 41 degrees.
Humidity is expected to reach almost 50 per cent during the week.
Of course at this time of year, the bureau likes to add the rider there may be thunderstorms in the afternoons and evenings.
Melbourne, Adelaide and Canberra are likely to experience their first 30 degree day of the season this week, while parts of western Sydney could nudge 40 degrees.
A mass of hot air originating over northern Australia will sweep across the nation's south and southeast later this week.
The air is being transported out of the tropics by a burst of northwesterly winds, which will develop ahead of an approaching cold front and low pressure trough.
While temperatures will gradually rise over the space of a few days, the hottest part of the air mass will sweep over Australia's south coast on Thursday, before targeting NSW and the ACT on Friday.
The hottest recorded October day in Katherine was 46.2 degrees back in 1991.
The average maximum temperature for October is 37.7 degrees.
