Latest ECMWF ensemble forecasts place Warsaw's April 5 high near 20°C under a high-pressure ridge ushering mild southerly flow, boosting trader-implied odds for 19–21°C outcomes to over 65% combined, while GFS runs introduce variability with potential cooler 17–18°C scenarios from increased cloud cover. IMGW short-range guidance aligns cooler at 13–15°C but has trended warmer in recent 24-hour updates amid observed above-climatological temperatures (early April average ~13°C). Key differentiators include insolation levels, exact ridge positioning, and boundary layer mixing; light winds heighten sensitivity to diurnal heating. New model cycles and IMGW bulletins on April 4 could refine consensus amid inherent short-range forecast uncertainty.
