A sweltering inland air mass will filter across southeastern Australia on Sunday, bringing scorching autumn heat.<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;201341983&quot;:0,&quot;335551550&quot;:1,&quot;335551620&quot;:1,&quot;335559685&quot;:0,&quot;335559737&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:279}">&nbsp;
This heat will be drawn from the Australian interior by a broad low pressure trough and cold front crossing the country&rsquo;s southeast, leading to increasingly hot temperatures into the weekend. The hottest temperatures are expected on Saturday over the far southwest of NSW, where the mercury will hit the low 40s, with heatwave conditions <a href="https://www.weatherzone.com.au/news/scorching-autumn-weekend-in-four-capital-cities/1890443">extending into South Australia and Victoria</a> as well.&nbsp;

Intense burst of autumn heat to scorch NSW, Victoria and SA

The Australian region has set new sea surface temperature records on each of the past five months, with the oceans around Australia expected to stay abnormally warm throughout autumn.
Rising ocean temperatures are one of the most obvious impacts of climate change and the last five months have been remarkably warm in the waters around Australia.
The map below shows the sea surface temperature anomalies around Australia in January this year. The red shading shows areas that were warmer than average for January and the darker red off the country&rsquo;s northwest coast show where sea surface temperatures were more than 3&deg;C above the long-term (1991-2020) average.

Monthly sea surface temperature anomalies in the Australian region have been more than 0.8&deg;C above the 1961-90 average since the beginning of 2023. The anomaly in summer 2024-25 was +1.01&deg;C, easily beating the previous summer record of +0.89&deg;C from 2023-24.

Warmer seas near Australia enhance evaporation and add more moisture into the atmosphere. Unsurprisingly, dew point temperatures were above average for most near-coastal regions of Australian in summer 2024-25.

Higher dew point temperatures make it feel warmer because the extra atmospheric moisture makes it harder for your body to lose heat through the evaporation of sweat. So, if you live near the Australian coastline and thought last summer felt muggier than usual, you weren&rsquo;t imagining it.
Looking ahead, computer models predict that sea surface temperatures will remain higher than average around Australia throughout spring.

<h3>Canberra</h3>
Maximums on Monday and Tuesday will be around 12-14 degrees lower than Saturday&rsquo;s expected top of 35&deg;C, but the effects of the cold snap in the nation's capital will be most strongly felt early in the morning, will overnight lows dropping to single digits, while the <a href="https://www.weatherzone.com.au/nsw/snowy-mountains/perisher-valley">NSW ski resorts</a> should see subzero temps with frost on Tuesday morning.
<h3>Sydney</h3>

Temperatures to plummet in autumn cold snap

Another big spring storm system will cause strong winds, heavy snow, potential blizzard conditions, freezing rain, and severe storms across the US this week.
<h2>Bomb cyclone on the way</h2>
A low pressure system is expected to rapidly intensify as it moves from the Rockies into the Central Plains on Friday, March 14. This low may intensify fast enough to be classified as a &lsquo;bomb cyclone&rsquo;, which refers to a low pressure system where the central pressure drops by 24 millibars (mb) over a 24-hour period at 60 degrees latitude, or 14 mb over a 24-hour period at 30 degrees latitude.
Bomb cyclones are dangerous systems that typically produce powerful winds and heavy precipitation. With this week&rsquo;s low being positioned closer to 40 degrees latitude in northeast Colorado on Friday, a drop of approximately 18 mb would suffice for it to be classed as a bomb cyclone. Recent runs of the European ECMWF and American GFS models are somewhere in the range of a 20-25 mb drop in 24 hours, which is more than enough to meet the definition.

Image: Forecast wind speed and mean sea level pressure at 21 UTC on Friday, March 14. Strong winds are forecast to develop over the Plains, with wind gusts exceeding the labeled sustained winds shown here. Source: tropicaltidbits.com
The low-pressure center is forecast to move from the Central Plains northeast through the Upper Midwest for Saturday, March 15, then into Hudson Bay on Sunday, March 16. A cold front associated with the low will also sweep across the country over the weekend, moving to the East Coast on Sunday night before exiting offshore early Monday, March 17.
<h2>Get ready for wind, rain, ice and snow</h2>
Before getting into the Plains, the system will have already brought widespread precipitation and strong winds to the Western US, including areas of heavy mountain snow, on Wednesday, March 12, and Thursday, March 13. But once in the Plains, the system will make for much more hazardous conditions.
Bomb cyclones are known to cause many weather issues, but the main concern is usually high winds. In fact, when also including the downsloping off the Rockies and into the Southern Plains, wind gusts may peak over 70 mph across Texas on Friday.
Strong winds will continue through the weekend, following the system east across the country. Though winds may only be in the 40-50 mph range for those across the Midwest, it will likely coincide with potential for heavy snow and freezing rain across the eastern Dakotas and Minnesota.
Enough cold air will be ingested into the low pressure system to produce bands and clusters of heavy snow on the northwest side of the low&rsquo;s track, but will probably wait until Friday night to materialize. Starting off as rain and transitioning to snow could make for some period of freezing rain in these areas as well. With the winds howling around, extra damage may occur from the ice and wet snow. Blizzard conditions may also develop from Saturday.

<h2>Severe weather in the South</h2>
To the south, several more rounds of severe weather are currently being forecast by the Storm Prediction Center. Areas near the Mississippi River are the focus on Friday, with that shifting to the eastern Midwest down to the Gulf of Mexico for Saturday, and along the East Coast for Sunday. All hazards will be possible, but strong winds and tornadoes will be the main threats. Those outlooks will continue to be updated and can be found here: https://www.spc.noaa.gov/products/outlook/.
To go along with the threat of thunderstorms, heavy rain will be possible across the Gulf Coast and Mid-South, areas that have dealt with flooding recently and could have issues with more flooding.

To go along with the threat of thunderstorms, heavy rain will be possible across the Gulf Coast and Mid-South, areas that have dealt with flooding recently and could have issues with more flooding.


Another big spring storm system will cause strong winds, heavy snow, potential blizzard conditions, freezing rain, and severe storms across the US this week.

‘Bomb cyclone’ to spread severe weather through US later this week

Sydney, Melbourne, Adelaide and Canberra will all reach the mid-thirties this weekend, with temperatures nudging 40&deg;C in the suburbs of Sydney, Melbourne and Adelaide.
<ul>
<li>The hot weather will reach Adelaide first, where tops of 37&deg;C and 38&deg;C are expected on Friday and Saturday, while Elizabeth in the city's outer north should reach 40&deg;C.</li>
<li>After a brief burst of midweek heat in Melbourne this Wednesday, temps will again soar on Saturday, with a top of 37&deg;C predicted in the city, while several suburbs including Tullamarine can expect 39&deg;C.</li>
<li>While the heat will dissipate in Adelaide and Melbourne by Sunday, both weekend days will be hot in Canberra, with maximums of 35&deg;C and 34&deg;C on Saturday and Sunday respectively.</li>
<li>After a soggy start to this week, Sydney will dry out and warm up over the next few days, with heat peaking on Sunday with a max of 35&deg;C in the city and temps reaching 38&deg;C in the outer west.</li>
</ul>
The heat across the southeast will be caused by warm, dry northwesterly winds ahead of a much cooler southwesterly change expected early next week. So the autumn heat shouldn't be too uncomfortable in terms of humidity, although major weekend sport could still be affected.

Scorching autumn weekend in four capital cities

A late-season surge of tropical moisture will cause an increase in rain and thunderstorms over northern Australia in mid-to-late March, along with an elevated risk of tropical cyclone activity near Australia.
Forecast models predict that an active phase of the Madden-Julian Oscillation (MJO) will pass to the north of Australia during mid-to-late March. When the MJO is active near Australia, it typically causes an increase in clouds, rain and thunderstorms in the tropics.
Rain and thunderstorms are expected to become more active over parts of northern Australia from this weekend into next week. This increased tropical moisture should also contribute to periods of wet and stormy weather over the southern half of Australia in the coming fortnight too.
The map below shows the forecast accumulated rain over the next seven days from the ECMWF model, with wet weather likely to affect part of every state and territory.
&nbsp;<img src="https://news-images.weatherzone.com.au/twc/aus_rain_20250311.png" alt="" width="1920" height="1080" />
Image: Forecast accumulated rain in the seven days ending at 11pm AEDT on Monday, March 17, 2025.
The presence of the MJO will also boost the likelihood of tropical cyclone activity near northern Australia in the coming fortnight. Some forecast models are already hinting at the potential for a tropical cyclone over the Indian Ocean to the northwest of Australia late next week. It&rsquo;s too early to know whether this system will form, but meteorologists will be keeping a close eye on the Australian tropics in the coming weeks.

Rain and storms to increase over northern Australia

A trough crossing southern SA has sparked as many as 40 bushfires due to a combination of dry lightning and parched countryside experiencing <a href="https://www.weatherzone.com.au/news/adelaide-facing-driest-summer-in-33-years/1890381">ongoing severe rainfall deficiencies</a>, with fires also sparked in Victoria.
The dry lightning outbreak started on Monday evening and has continued through to the middle of Tuesday before progressing eastwards into Victoria, with more than 400,000 lightning strikes&nbsp;recorded within 500km of Mount Gambier in southeastern SA&nbsp;between Monday morning and Tuesday lunchtime.&nbsp;
While a few SA locations were lucky enough to see falls of 10mm or more (<a href="https://www.weatherzone.com.au/station/SITE/26091/daily-summaries">including Coonawarra with 24.4mm</a>), most locations saw barely a drop &ndash; and certainly not enough to negate the effects of a lighting strike.&nbsp;
A SA Country Fire Service spokesperson said that nearly all of the service's 68 brigades and trucks in the state's southeast have been actively responding to calls throughout the night and into the early morning.
