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

As prognosticated earlier, today will be the last day of unsettled weather for a bit. Yesterday, most rain fell in the eastern Guadalquivir Basin, east of Jaen. Last night's Gibraltar sounding does not show a great deal of instability, so amounts will again be light except in a few mountainous areas.
The dry weather will continue through at least midweek, with a warming trend beginning Sunday as easterly flow establishes itself. Enjoy, you snowbirds!

Rainbands trekked across the western two thirds of Andalucia overnight. Yesterday's Guadalquivir precipitation map shows the heaviest amounts in the sierra north of Cordoba, where some thunderstorms developed. Also the mountains of Cadiz and Malaga province received a dousing.
The Gibraltar sounding shows some moderate instability, so today again we should see showers and thunderstorms, with maximum effect over the mountains. As I suspected, the upper level trough primarily responsible for the precipitation is reinforcing its southern extent, so the showery pattern will persist until early Friday. Then conditions will be settling down, toward fair but cool weather this weekend.

...and just in time for a return to unsettled weather. Perhaps some folk prefer I stay away!
A weak but very persistent upper-level trough will provide enough lifting to generate some showers, at least through Wednesday and probably longer. This trough is associated with a weakening surface cyclone to the northwest of Iberia, so precipitation will be heaviest in northern Spain. While showers in the south will be scattered in coverage and not generally heavy, they too will be persistent and ultimately affect most of the region. The current radar shows two rain bands over Huelva and Cadiz provinces.
Since this is May, there will be considerable sunshine between showers. The best chance of thunderstorms will be over mountains. Temperatures will be slightly below seasonal norms.

...outside of Andalucia. Yesterday I was in a convective shower that produced conical graupel (hail less than 5 mm in diameter) in Avila, central Spain (Avila sits at 1200 m elevation, and it was plenty cold). Crossing the mountain pass to the south, there was mixed rain and snow. And all this with very little trigger evident on the weather charts or models. Mountain weather is really something apart!
