Weekly Weather Watch: Tuesday, March 5th, 2024
If you haven’t heard the headlines about the amount of snow in the Sierra Nevadas, it’s worth a “Google” of the Mammoth area to see some pictures of the deep snow they’ve received. In other headlines, we have tremendously bad grassfire news out of Texas and Oklahoma during the past week.
For this week, here are the items that have my attention and perhaps yours.
For the States, heavy precipitation hits the West Coast from the 9th to 11th, heavy snowfall for the Central Rockies (mostly Colorado) the 7th and 8th, severe thunderstorms are possible across the South the 7th and 8th before that system drenches the South and East with heavy precipitation through the 10th. (image follows)
For Canada, extreme cold warnings are in the near term for AB and BC; cold temperatures will persist. Moisture will spread across the Prairies later this week, then the East for the weekend and early next week.
For Alaska, troughing will keep the cold coming, and moisture will favor the south and southeast.
For Hawaii, strong trades will keep moisture on the mountains and the windward side of the islands.
Let’s get to the animation showing the storm flow for the next ten days:
From that storm flow, let’s look at the precipitation totals first and then the snowfall totals.
The driest areas are those along the lee side of the Rockies from Alberta to Montana. The Pacific Coast to catch more than half-a-foot of water, the southeast to pick up several inches, and some needed water to fall on the Corn Belt. In terms of snowfall, how much?
The mountains, eastern Canadian Prairies, New England, and the Maritimes have some notable snow on the way.
In terms of temperatures, I mentioned the extreme cold warnings for parts of Canada where the cold has a firm grip on the west - the colder temperatures are covering much of the Western U.S. this week with milder conditions for the eastern half of the States and Canada.
That’s the brief for this week. I need to thank several folks including Beef Farmers of Ontario, the Alberta Beef Industry Conference, and Compeer Financial for having me speak recently about the year’s weather patterns and changes ahead with loss of our current El Niño turning into La Niña. If you are a member/attendee of any of those entities your private web links given you will have the seasonal and monthly outlooks through the year (lasting about one more month before I’ll need to take those pages over for future speaking engagements). Blessings! -Matt.
A prolonged and dangerous heat wave will dominate the weather story this week as much of the central and eastern United States experiences some of the hottest weather of the year. Heat index values above 100 degrees will become widespread, with some communities seeing readings between 105 and 115 degrees and little relief at night. At the same time, several rounds of severe thunderstorms are expected from the High Plains through the Upper Midwest and Northeast, bringing the threat of damaging winds, large hail, and localized flash flooding. Out West, cooler-than-normal temperatures will continue while dry conditions keep wildfire concerns elevated across parts of the Four Corners and Great Basin. Air quality is an issue across Alberta to Quebec due to wildfire smoke. Heavy precipitation is possible from far eastern Saskatchewan to far western Manitoba.
