Weekly Weather Watch: Monday, May 6th, 2024
Welcome to May’s first weather briefing. The Members received their May outlook on the 1st, which included heavy precipitation areas. To expand that, here is a specific look at this week's significant weather areas (image 1). Many places will be hit with heavy rainfall and may flood (image 8), and others with heat, drought, and wind (image 11).

Besides the heaviness of the rain, another serious threat this week will be a substantial risk of damage from thunderstorms across the Central Plains today, which will spread eastward later this week. Severe weather outlooks are shown below (Images 2, 3, 4, 5). Here are the weather items that will make headlines this week:
There is a Moderate to High Risk of severe thunderstorms over parts of the Central/Southern Plains on Monday and a Slight Risk across the Ohio Valley on Tuesday. (Images 2, 3, 4)
There is a Slight Risk of excessive rainfall over the Northern High Plains and Central Plains/Middle Mississippi Valley on Monday. (Images 7, 8)
Heavy snow over the higher elevations from the Pacific Northwest to the Northern/Central Rockies. (Image 9)
Central Gulf Coast States to Appalachians/Southeast U.S. Heavy Rainfall Threat into Thursday/Friday. (Images 7, 8)
Rapid onset drought is possible for portions of Central Florida. (Images 10, 11)
For Canada, the highest threat comes from Alberta, where heavy rain is expected tonight and Tuesday. Rain will begin this afternoon and continue through Tuesday night. Widespread rainfall totals of 50 to 70 mm are likely. Locally, higher amounts of 80 mm or more are possible. Rain will taper off on Wednesday. Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible. Watch for possible washouts near rivers, creeks, and culverts. (Image 7)
Stay alert today; there is a significant threat of damaging thunderstorms across the Central and Southern Plains. There is a 30% chance of tornadoes and a 45% chance of damaging hail across parts of Oklahoma and Kansas.

Be well, and have a safe week! - Matt.
As we close out 2025 and ring in the new year, the weather pattern stays anything but quiet. A multi-day lake-effect snow event is burying areas downwind of Lakes Erie and Ontario, where over 3 feet of snow could fall in the most persistent bands—creating whiteout squalls and treacherous travel through New Year's Day. Meanwhile, Arctic air is spilling deep into the Southeast, sending temperatures below freezing as far south as Florida, with frost and freeze alerts in place. On the other side of the country, a Pacific storm system will bring rounds of heavy rain and a flash flood threat to Southern California, especially around Los Angeles, starting late New Year's Eve. Elsewhere, a couple of fast-moving clippers will spread freezing rain and snow to Alberta, then snow across the Midwest, Ohio Valley, and into New England, while a developing storm may bring soaking rain and thunderstorms from the Deep South to the Southeast Coast by the weekend. Even Northern California faces an atmospheric river event late week, setting the stage for an active and disruptive start to 2026.
