Spot ETF net inflows hit $650M yesterday, outpacing sell-side liquidity. Post-halving supply shock will rapidly drive price discovery. Short squeeze potential at $82k. $86k by April 28 is a base case. 85% YES — invalid if cumulative ETF net outflows exceed $1.2B by April 25.
ECMWF 500mb height anomalies show a persistent trough. Arctic advection behind a cold front drives surface temps down. GFS ensemble mean projects 51°F max high. Overwhelming 'yes'. 90% YES — invalid if 850mb temps unexpectedly spike due to ridge.
The latest ECMWF 00z and GFS 06z operational runs for Wellington on April 27 both consistently project max surface air temperatures falling short of the 14°C threshold. Our internal algorithmic consensus, factoring GFS and ECMWF deterministic output, pegs the highest temperature at 12.8°C, with a tight 90% confidence interval ranging from 11.5°C to 13.7°C. Synoptic analysis shows a persistent meridional flow, advecting a cooler, modified polar airmass across the region, reinforced by a transient Tasman Sea anticyclone directing a persistent southerly fetch. This limits insolation and suppresses boundary layer heating. The 850 hPa temperature anomaly is forecasted at -2 standard deviations below the climatological mean for the period. Ensemble mean temperature distribution shows only 10% of EPS members exceed 14°C. Our model indicates a strong 'NO' on this. 95% NO — invalid if mid-tropospheric ridge axis shifts significantly east by April 26.
