Citaat van: Noordenwind op wo 30 sep 2026 - 19:10Ben benieuwd, we kunnen best weer een golf water gebruiken. Wat houd een waterinhoud van 40+mm eigenlijk in? KNMI berekend maar tot lokaal 20+mm.
Verder gaat het KNMI voor mogelijk een klap onweer in regio ZO
Opvallend is de hoge waterinhoud, nabij het front 40+ mm. Dus plaatselijk kan het even stevig doorregenen. Accumulaties grootschalig in de orde van 5-10 mm/24 uur met plaatselijk uitschieters van 20+ mm.
Aldus KNMI
CiteerFrom NW to NE France into Belgium/the Netherlands, a N-ward pushing warm front with better tropospheric moisture content offers a belt of meager to modest elevated MUCAPE. A short-wave crosses NW France during the day to SE England, which induces a somewhat augmented thunderstorm risk, which spreads from NW France to the Netherlands during the day.
Elevated CAPE and ineffective SRH probably support a few elevated rotating updrafts with ID2-EPS highlighting W Benelux to the Netherlands during the night. Small hail and heavy (but short) bursts of rain are forecast but even ensemble data has only meager gust signals. Still a low-end level 1 upgrade was performed as some concern exist for a temporal overlap during the evening into the night for robust mid-level MUCAPE with strong speed/directional shear which could support isolated hail, approaching our severe criterion.
