Weather forecast for the region

 

Thursday:

Weak (4-7 kts) SSW in the morning, gradually veering towards SW at noon and then veering even further to WSW in the evening. Gradually getting slightly stronger around noon due to heating over the land (8kts gusting to 15kts) and easing in the evening (6-10kts).

Some showers possible mainly over the land.

 

Friday:

Slightly backing after midnight due to an approach of the first weak front which is about to pass the region in the morning. Wind W-WSW, 8-12kts gusting up to 18 kts. Veering to WNW after the front passage and easing a bit.

Getting stronger toward noon again, 15-20 kts, gusting up to 28 kts in the afternoon. Westerlies. Easing a bit in the night toward Saturday but still gusting up to 24 kts.

Some showers and even thunderstorms in the early morning,  intensifying again in the afternoon due to cooling aloft.

 

Saturday:

W-WSW, 14-18kts, gusting up to 26kts.  Mostly cloudy, with some showers.
