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

A train of weak fronts from the West will trigger bouts of rain for the next 36-48 hours. There is abundant moisture evident on the Gibraltar sounding; fortunately, the focusing of atmospheric dynamics is not great, otherwise flooding would be a threat. This focusing seems to be stronger tomorrow than today, however, so the situation bears watching. Strong winds should appear tomorrow as well.

A weak cold front is triggering a north-south band of precipitation across Portugal at press time, and these features will sweep across the region this evening. Precipitation amounts will be light, however, just a few millimeters in most locales. In fact, the most vigorous aspect of the front appears to be strong southwest winds.
It looks like the weather next week will be quite different, as high pressure that has been in charge over Iberia moves out. (This is good news for Madrid, which has been experiencing air pollution episodes.) Rain will move out tomorrow, but heavier rain invades Andalucía again on Tuesday.

Here is a visible satellite image from this morning, showing fog that extends well upstream into the Guadalquivir River valley (cyan arrows). With high pressure and light winds dominating Spain, moisture trapped in the valley cools overnight through radiative cooling and when the temperature falls to the (high) dewpoint temperature, voila! This fog looks dense and thick, so it may take a while to burn off today.
