Most of our weather moves from the west, but hurricanes in the Atlantic Ocean move to the west. Can you explain this?
Hurricanes move with the wind flow in the layer between the surface and approximately 40,000 feet aloft. During the summer and fall, a belt of more or less permanent high pressure extends across the Atlantic Ocean between the United States and northern Africa, paralleling the Equator.
Winds spiral out of the high in a clockwise direction and generate prevailing easterly flow across the tropical Atlantic, where most hurricanes form. Those prevailing easterlies steer hurricanes to the west, with a slight northward component. As hurricanes continue on that path, they eventually get caught in southwesterlies on the poleward side of the high pressure belt, and they “recurve” to the northeast.
The incredible beauty of Canada’s British Columbia always to takes our breath away–and these amazing photographs continue the tradition! Just look at these spectacular shots of the Province’s snow covered peaks from our friend Keith Heidorn, PhD—the Weather Doctor—ut of Valemount, British Columbia, Canada! Keith writes:
“We would love to be having US Thanksgiving weather here on Monday which is Canadian Thanksgiving. The forecast high it to be about freezing while the lows the last few nights have been near single digits Fahrenheit. But the clear, cold weather gives us great views of the surrounding mountains here in the Robson Valley. Here are a couple out my front door looking toward the surrounding foothills of the Canadian Rockies. Mount McKirdy is the ridge with the pointed peak and the massif is Canoe Mountain to our south.”
Amazing shots! Happy Thanksgiving to ALL of our neighbors in Canada!! And, MANY THANKS as always Keith for these spectacular photos!

You’ve got to love this. Mike Kellems share this Saturday sunset shot with us taken a few miles west of La Porte, Indiana Saturday evening. Beautiful shot–even captures the cool autumn-like this past weekend! THANKS Mike!

Sunday’s very chilly 44-degree high was more typical of Thanksgiving than just before Columbus Day, and it followed fall’s first widespread hard freeze that dropped Sunday morning lows into the middle and upper 20s except for areas very close to the lake. O’Hare International Airport’s 29 degrees was the coldest since April 2, when it dropped to 28, and Rockford’s 25-degree low broke a record dating back to 1987, when it was 26. The Chicago area, along with much of the Midwest and Plains, has been locked in a chilly pattern since late September with little prospect for warming in the short term. Snow covers much of the Northern Plains and Upper Midwest, and up to 5 more inches are expected Monday.
Storm to hit Pacific Coast
The Pacific Coast is bracing for a major wind and rainstorm this week, heralding the opening shot of what could be a stormy El Nino-influenced winter. The brunt of the storm is headed for areas from Northern California to Washington, where 4 to 8 inches of rain could fall driven by 60 mph winds.
I remember a wonderfully warm Halloween when we trick-or-treated until our legs wore out. I think it was 1955. Can you clarify?

Though the early 1950s featured several warm Halloweens, 1955 was definitely not one of them. That year Oct. 31 started out very chilly with temperatures in the 30s along with some snow flurries, and though it warmed up a bit in the afternoon, the high reached only 51. If your time frame was off a few years, you might be remembering the city’s warmest Halloween on record which occurred in 1950 with a summery 84 degree high. Other possibilities include 1952 (69 degrees), 1953 (70) and 1956 (68). After a string of recent cool Halloweens, last year turned out quite nice with the high temperature topping out at a balmy 70 degrees.
