Some rain, but only weak thunderstorms today

By: esteban9 , 7:32 AM GMT on September 16, 2010

The cloud band described yesterday is now draped across most of Spain, which will cut down on sunshine and usher in much cooler conditions area-wide. The Gibraltar sounding, which shows substantial dry air below 3 km, combined with a weakening upper disturbance, should mean that the risk of severe thunderstorms will be greatly weakened today. There will be some rain, especially in the afternoon through evening, but torrential downpours will be unlikely. AEMET seems to have caught on with this idea, as they have no alerts in all Spain today. Most of the thunderstorms that do occur will be in the southwest (Huelva, Cadiz areas) overnight, but since instability there won't be aided by daytime heating, I don't expect these to be severe either.

It still appears that tomorrow will see the heaviest and most widespread rain (including scattered thunderstorms)but, as the day progresses, this rain will shift gradually away from Andalucía toward the northern and eastern part of Spain, where a cold front will lie. By Saturday, the region should be dry, partly cloudy and much cooler (highs mainly in the upper 20s). So the weekend will be very pleasant for those who are looking for some sun, but also relief from the recent hot weather.

Another weak upper disturbance looks to follow up the current one, Monday and Tuesday. I don't anticipate much significant rain with that one.
