Recent days of unseasonable warmth were swept away by a cold front crossing the United Kingdom and western Europe. Not only is cooler air rushing across the region, but periods of rain as well.
Thursday was the hottest day of the week in London and the rest of southern England. In fact, it was the warmest September day in London since 2006 as the high reached 29.5 degrees C (85.1 degrees F).
After four straight days of high temperatures reaching 26 degrees C (78 degrees F) or greater in London, temperatures are expected to reach only 18 degrees C (65 degrees F) on Friday.
The cooldown will also reach France on Friday following several days of temperatures over 31 degrees C (88 degrees F). In fact, some parts of France experienced their warmest September temperatures in almost a decade. The high on Thursday reached a sizzling 33 degrees C (91 degrees F) in Paris, one of the hottest September days in recent years.
A cold front brought showers and thunderstorms across France and northern Spain Thursday night into Friday. Some of the thunderstorms contained strong winds and hail near Paris. Behind this frontal boundary cooler air will arrive on Friday leading to highs only near 24 degrees C (75 degrees F).
At this time, it appears the front will stall east of Paris, leading to dry and seasonable weekend for the city.
While Paris enjoys several days of pleasant weather following the frontal passage, the United Kingdom will not be as lucky as a cut-off low pressure system sits overhead leading to the threat of showers which can contain heavy downpours through the weekend.
The temperature roller-coaster ride will continue into the new week for the Washington, D.C., area.
The temperature roller-coaster ride will continue into the new week for the Philadelphia area.
The temperature roller-coaster ride will continue through St. Patrick's Day for the Boston area.
The temperature roller-coaster ride will continue into St. Patrick's Day for the New York City area.
Dry weather will exacerbate drought and fire danger concerns for California this weekend.
Those celebrating St. Patrick's Day through the weekend will be dodging showers.
The first storm referred to as a blizzard. March 14th-16th... An editor at the "Dakota Republican" in Vermillion, SD, described the storm. "A violent snowstorm driven by a heavy (northwesterly) wind, commenced about 12 o'clock last Sunday night (12th) and continued three whole days and nights. The weather was intensely cold and the heavy fall flying before a furious wind - blowing as only prairie winds can blow - rendered travelling exceedingly uncomfortable and dangerous, if not almost impossible (issue of March 17, 1820)."
