On 1st & 2nd Feb 2016 the Perth region has had record breaking cold mornings.
See comments by Ubique and wazsah #’s 5 and 6 here. Make max and min anomaly maps at BoM.
Click for min T anomaly for WA on 1st Feb odd the contour colours are not darker blue near Perth.
Max T anomaly for WA 1st Feb – cold day on Goldfields due cyclone Stan shooting through I suppose.
