Musings and forecasts of Andalusian weather and climate, from a veteran meteorologist.

Well, the computer models are now backing off on the major rainfall event from Thursday into Friday. There will still be rain, but if one follows these models, amounts will be considerably lighter and the Good Friday Semana Santa events saved. This is consonant with the weak upper-level jet stream attending the low pressure system. Nevertheless, models often undergo changes in their forecasts over time, so this event still bears watching.
In the longer term, this low actually recedes westward, well out into the Atlantic (in meteorological parlance, it "retrogrades."). However, the models have difficulty in forecasting such behavior, so again, this will have to be monitored. In any event, we seem to have replaced the high pressure and fair weather of winter with unstable, cloudy and showery conditions of spring. At least for the coming week. I'm sure the granjeros are grateful...
