Temperatures are very hot right now across France as a large high pressure system is in control of the weather. But that will change in a few days as a cold front is expected to cross northern France on Monday, followed by cooler temperatures. Behind the front on Wednesday, expect mostly cloudy skies and highs in the mid 70s F, or mid 20s C.
Models differ on the chance of rain for Thursday. Some show a completely dry day, while other show a disturbance in the mid and upper levels crossing northern France. I think there is enough of a chance of the later scenario that I needed to include a small chance of showers on Thursday. But the impact looks small if showers do occur, as it is a weak and fast-moving trough.
A ridge of high pressure is expected to build over the western Atlantic on Friday, and continue to build east into Spain and France over the weekend. It will provide dry conditions and warming temperatures, with highs peaking on Sunday in the upper 80s F, or lower 30s C.
I'll be away for a few days, so my next planned update will be on Tuesday.
