Record-setting warmth will yield to a true fall chill this week as sweeping shifts in weather patterns overtake the UK.
Temperatures will step back significantly on Tuesday after Monday's "parting shot" of summery warmth. The big shift, however, will happen with the passing of a strong cold front, between Wednesday and Thursday, when temperatures will go from about 3 to 6 degrees C above normal to 1 to 3 degrees C below normal.
Thus, highs Thursday, Friday and Saturday will range from 9 to 14 degrees C (48-57 F) across Scotland, Northern Ireland, northern England and much of Wales, and from 12 to as warm as 16 degrees C (54-61 F) elsewhere.
On Thursday and Thursday night, heavy showers sliding southeastward, off the sea and into northwestern UK, will even become wintry, with snow, sleet or small hail, over hills from Scotland and Northern Ireland into northwest England and North Wales.
The storm responsible for the wind, cold, rain and snow in the Northeast Friday and Saturday will slowly ease up for the balance of the holiday weekend.
A few days after a chilly storm departs the Northeast, warm weather will make a strong comeback in parts of the Midwest and the East later next week.
During Sunday's race, the skies will be variably cloudy with the risk of a few showers.
"This pup was literally singing when he saw his family," Michelle Karolicki, relocation program manager of the Central Oklahoma Humane Society, said about a reunion that took place on Thursday.
Another plunge of chilly air will set the stage for the risk of a frost and freeze centered Michigan, Ohio, West Virginia and other nearby states this weekend.
Downpours and locally severe thunderstorms over the Central states will not only foil holiday weekend activities, but will also put some lives at risk.
New England (1967)
(25th-26th) Coastal New England battered by a great Nor'easter. Winds mounted to 70-80 mph on the coast. Blue Hill had sustained winds of 60 mph and Logan had sustained winds of 50 mph.

Temperature dropped to 31 degrees at Pittsfield on the 30th for a remarkable end of May freeze.
