Brisbane is bracing for a scorcher and is likely to see its hottest March day in eight years. A hot air mass is currently lingering over southeast Queensland and is only looking to intensify as the morning turns to afternoon. Light north/northwesterly winds will prevail for the remainder of the morning, at times becoming calm. A seabreeze will cool eastern suburbs from early afternoon then reach the CBD between 2pm and 4pm but not reach far western suburbs until at least late afternoon. Brisbane's western suburbs have the potential to heat up to 40 degrees with less impact from the seabreeze. Again, humidity will play a major role in making it feel hotter. As a result, the north/northwesterly land breezes will battle the east/northeasterly seabreeze, slowing the heating before eventually cooling. This seabreeze, however, will boost humidity levels, making it feel very muggy and sticky. In the city it will feel three or four degrees hotter than the actual temperature, feeling as hot as about 40 degrees early afternoon. If the city reaches 38 degrees this afternoon, which may be a little bit optimistic, it would be the hottest March day since 1965. Being more realistic however, if the CBD exceeds 36 degrees, it will be the hottest March day since 2007. The chances of this scenario playing out are pretty good with a forecast maximum of 36 degrees. At 11am, the mercury was sitting at 32.5 degrees, with a light seabreeze at times making it feel like 36 degrees. A southeasterly wind change will arrive this evening, bringing more significant cooling and returning temperatures to near average for the next few days.
