According to the latest run of the ECMWF model, Monday’s low is a little bit slower in crossing the country. That won’t stop it ruining a perfectly good Bank Holiday Monday, even though it might remain dry in the extreme east till late afternoon. Not all models agree with the intensity and track of the low, notably the GFS. There’s still plenty of time for things to change in the next five days, but I think we can say safely say that this low marks the end of the recent good run of anticyclonic weather we had in April. The next ten days look unsettled, wet and windy across all of IONA, and by the end of it even the parched southeast should have picked up an inch or more of rain, interestingly one of the driest places maybe the inner Hebrides.
