Another round of unseasonable warmth is building across parts of the United Kingdom and western Europe.
The past weekend featured cooler temperatures across the region as a storm system passing through northern Europe briefly ushered in some cooler air.
This cooldown is already just a memory as a ridge of high pressure building into the region has pumped unseasonable heat from Spain to France and the United Kingdom.
Since the beginning of July, there have been only two days below normal for London, and that same heat has been seen across the entire western part of the continent, as Paris, France, is nearly 2 degrees C (3.2 degrees F) above normal since July 1, and looking even farther south, Madrid, Spain, has had temperatures departures averaging over 3 degrees C (6.5 degrees F) since the start of July.
This heat has all been from a strong high pressure area that has set up over Europe, pushing most of the storms well to the north of England and Ireland. Spain and Portugal have had some fires around as the strong high pressure has kept it quite dry. Madrid received 0.02 of an inch of rain in July and only 0.25 of an inch of rain in August. Though this is the typical dry period, rainfall is well below normal even for this time of the year.
The warmth began to build across England on Monday and Tuesday as temperatures climbed into the low and middle 20s C (middle and upper 70s F). The hottest weather is expected on Wednesday and Thursday with highs reaching the upper 20s C (lower 80s F) across southern England.

In Paris and surrounding areas, temperatures were seasonable on Monday. The unseasonable warmth began to build on Tuesday as temperatures climbed to around 26 degrees C (79 degrees F). Heat continued to build across France on Wednesday as highs climbed to near 30 degrees C (86 degrees F) across Paris.
This unseasonable warmth will continue for Paris on Thursday and Friday with a high of 30-31 C (86-88 F) on Thursday. The high on Friday is expected to be 28-29 C (82-84 F).
The heat will end across the United Kingdom by Friday, then temperatures will turn cooler across France and Spain over the weekend. As the cold front presses through the region, heavy and gusty thunderstorms will be possible, with the greatest threat of damaging storms being across France.
