Blue and frosty this morning.
Light SE winds which I'm guessing are partly due to the prevailing upper wind and partly katabatic.
Upper winds are slightly more Southerly.
Trigger temperature at 12.00am is 10 degrees and the forecast temp for Tauranga is 14 degrees. Sounds Good BUT we have a strong inversion from about 4500ft upperwards. Typical of winter high pressure systems...
Also the dew point gets quite close to the dry air lapse rate.
So some thermals later today but limited by the inversion (maybe 4500 ft if it gets warm enough) but if it really gets going I'm predicting it will overdevelop or at least spread out (a bit like late yesterday).
