No sign of the season’s first frost just yet
At the weekend
THE Anzac long weekend produced some perfect weather for the Southern Downs and Granite Belt. Saturday was partly cloudy at times with high level cirrus cloud producing a colourful sunset. Winds were light from the south-west, tending easterly at times. The day reached a high of 25 degrees after an overnight low of 10.
Overnight Saturday cloud began to move in and it was overcast Sunday morning as an upper level trough and associated surface trough moved through the district. A few light showers were around in the afternoon. Sunday had a high of 23 degrees after an overnight low of 14.
THE upper and associated surface trough will interact with the ridge along the coast to generate showers and the occasional storm over the Southern Downs and Granite Belt early in the week.
A cold front should start to enter the state by mid-week and will affect the region later in the week.
TODAY will see the upper and surface trough moving off the coast and producing some showers and the chance of a storm from mid-morning, mainly in the east. The ridge along the coast will continue to be maintained by the high in the Tasman Sea and feed moisture into the troughs. It should be overcast for most of the day and winds should be light to moderate from the south to the south-east. 13-22.
TUESDAY should be fine and sunny with some light high-level cloud around. The trough should move offshore overnight Monday while the ridge should move into our region. Winds will be light from the south-east. A cold front will enter the state from the south-west and may produce a shower or two in the far south-west. 11-24.
WEDNESDAY should be overcast as the cold front starts to affect our region from the south-west. The cooler air will interact with the warm, moist inflow from the east and this should generate showers and the chance of a storm across the region during the afternoon and evening. Winds should be from the north-west during the morning before swinging to the west during the afternoon. 10-25.
THURSDAY should see clear skies as the cold front dominates our region and keeps us fine. A surface trough should develop during the morning while the ridge near the coast moves slightly north. Winds should be light from the south-west tending easterly at times. There is a chance of a patchy shower in the late afternoon near the ranges. 11-23.
FRIDAY should see the ridge along the coast to the north of the region and push high-level moisture across the Downs. It will be cool in the morning as a cold pool of air sits over the region. No rain is expected and winds should be light to moderate from the west for most of the day. 8-22.
AT THIS stage both Saturday and Sunday should be overcast and may see a shower both days.
Temperatures will be cooler with a high around 20 degrees both days and single figures in the mornings. Showers and a chance of a storm across the region are more likely on Sunday.
Temperatures should be in the mid 20s with overnight lows in the low teens.
