Westy's Weather: Perfect Easter weather
At the weekend
MOTHER Nature turned it on this weekend. Saturday started out cool with a low at 3.30am of 4.4 degrees and an apparent temperature, that's the temperature on your skin, of 3.2. It warmed up fast to a perfect autumn day with clear, blue skies all day. After a cool night, Sunday morning was perfect with no wind and a bright, warm sun rising over the mountains. It stayed sunny all day and there was a high of 25 degrees after an overnight low of 6.5.
THIS week has a surface trough stretching from the gulf to around Fraser Island. This trough is being stabilised by a dry mass of air that has been pushed into Queensland by a high over Victoria. This high will keep Queensland dry and clear for the next few days.
TODAY will see the high near Victoria continue to push a dry air mass into Queensland. A ridge should form over the region during the day and this will keep the clouds away and the sun shining. Overnight temperatures should start to warm up slightly to the low teens, keeping the first frost at bay. Winds should be light from the west, tending north-west at times, with temperatures from 10 to 27 degrees.
TUESDAY should see a surface trough and an associated upper trough move into the south-west region of the state. No rain is associated with this trough, but due to the easterly airflow generated by the high as it moves into the Tasman Sea, the weather will most likely turn cloudy. Winds should be light from the north-west before swinging to the northeast during the afternoon. Temperatures should range from 12 to 26.
WEDNESDAY will see the surface trough start to march across the state. It should be overcast in the morning and this should clear during the afternoon. There is a chance of an isolated shower in areas west of Warwick. Winds should be from the west during the morning before swinging to the north-east during the afternoon. Temperatures 12 to 27.
THURSDAY should see another surface trough enter the south-est region of the state and start to move through southern parts by the afternoon. This trough may generate some showers and the chance of a storm over the border region during the afternoon, as another surface trough develops over this region. It should be partly cloudy for most of the day and winds should be light from the west tending east during the afternoon. Temperatures 12 to 27.
FRIDAY should see the surface trough move offshore and allow an easterly airflow of moisture into the south of Queensland. There is a chance this will develop into a shower or two in the afternoon, mostly over border regions. Warwick may see a shower close to the ranges. It should be partly cloudy during the day, but the cloud may fill in near late afternoon. Temperatures 12 to 26.
AT THIS stage both days should have showers and a chance of a storm across the region, more likely on Sunday. Temperatures should be in the mid 20's with overnight low's in the low teens.
