A gusty southerly change is set to sweep up the NSW coast, bringing a much-needed cool-down and the possibility of showers and storms. Meanwhile, the western parts of the country will experience significantly building heat thanks to a developing trough.

00:00Hello, Sarah from the Bureau here with your national weather forecast for tomorrow.
00:04So that's Wednesday, the 18th of February.
00:06So we'll start off by taking a look at tomorrow's synoptic map.
00:09We have this cold front across the southeast with showers clearing out into the Tasman
00:14Sea, but with an associated trough and gusty southerly change pushing up the east coast
00:19of New South Wales, bringing relief to the warm temperatures, but also bringing with
00:23it a risk of some showers and storms.
00:25Across our tropical north, very humid conditions with widespread showers and storms continuing,
00:31and even a risk of some heavy rainfall with any of those storms.
00:34While this high pressure system in the Great Australian Bight is bringing generally dry
00:39and settled weather across the south, and temperatures really starting to build through far western
00:44parts of WA with that heat trough.
00:47So let's now go around the country, state by state, taking a closer look.
00:50For Queensland, just the possibility of some morning fog patches about the southeast, clearing
00:56to a mostly dry and sunny day.
00:59But elsewhere across southern parts, just the risk of a shower.
01:03Through central and northern parts, however, showers and storms are expected, tending more
01:07scattered throughout the north, where heavy rainfall is possible through those northern
01:11areas and as well out in the northwest.
01:14For Brisbane, a mostly sunny day and a top of 31 degrees.
01:19Down in New South Wales, we do have that trough and gusty southerly change pushing up the
01:24coast and bringing with it a risk of showers right throughout that southeastern area, with
01:29afternoon showers and storms developing near and just behind that gusty change.
01:35Elsewhere across the state, mostly sunny conditions in the northeast and out in the west.
01:40For Sydney, a chance of an afternoon shower or storm with that gusty southerly change that
01:46we're expecting to move through around during the early afternoon, a maximum of 34 degrees,
01:52but much cooler conditions are expected once that change does move through.
01:56For Canberra, a risk of an afternoon shower and a top of 30 degrees.
02:01Down in Victoria, just a few showers throughout eastern parts contracting and clearing out into
02:07the Tasman Sea. Elsewhere though, dry and partly cloudy conditions, daytime temperatures are
02:13expected to be slightly below average for this time of year.
02:17For Melbourne, there is a risk of an early morning shower about the far eastern suburbs,
02:22clearing to a partly cloudy day, a top of 25 degrees.
02:27Down in Tasmania, just a few showers about the windward slopes and coasts in the west and
02:33then showers really starting to increase during the afternoon with the passage of this trough.
02:39Daytime temperatures near average and for Hobart, we're expecting a chance of a shower
02:44most likely during the afternoon, a top of 22.
02:48For South Australia, it's going to be a generally dry and mostly sunny day, apart from the risk
02:53of a shower or storm about the very far north. Daytime temperatures in the low to mid-20s near
02:59the coast but grading into the low to mid-30s as we head further inland.
03:05For Adelaide, a partly cloudy day and a top of 25 degrees.
03:10Now for WA, we do have this high pressure system in the south that's going to be bringing generally
03:14dry and settled weather with morning fog patches through the south clearing to a sunny day.
03:21As we head further through into the interior though, there's an increased risk of showers and storms.
03:26Temperature is really starting to build about that west coast as the winds turn easterly,
03:32so bringing much drier and hotter continental air up over the coast.
03:37For Perth, we're expecting a sunny day in a top of 34 degrees.
03:42Now for our tropical north, really humid conditions with showers and storms continuing to be widespread
03:48across the region and there is a risk of those heavy falls in the vicinity of these troughs or the
03:54low pressure systems.
03:56For Darwin, we've got showers and the risk of a thunderstorm a top of 32.
04:01Now, if you are wanting a more detailed forecast for your local area, you can head to the Bureau's website,
04:07the Apple social media. Otherwise, we'll see you again next time. Bye for now.
