Weekly Weather Watch: Monday, April 15th, 2024
Several items should be on your weather radar for this week. I won’t dilly. Here are the heads-up events to watch for during the week.
Severe weather and isolated flash flooding to the Plains on Monday, then the Mississippi Valley on Tuesday. There is a threat of some severe weather from the Upper Ohio Valley east through the Mid-Atlantic on Monday. (Outlook maps below)
Heavy snowfall is expected over the next couple of days for higher elevations of the northern Cascades, northern/central Rockies, and eastern Great Basin (Snowfall maps below)
Dangerous fire conditions for the High Plains Monday due to strong winds.
In Alaska, coastal rain and mountain snow ramp up later this week with a low offshore.
In Hawaii, the current system exits, and a normal trade regime with typical windward showers to set up later this week.
In Canada, a quick change to hit AB and the Prairies on Monday with a cold front’s arrival. A long period of snowfall with total amounts of 10 to 20 cm is expected. Heavy snow will begin this evening and taper off by Wednesday morning for most areas. Localities near the American border will see snow intensify on Tuesday. (Snowfall maps below)
Overall, a cooler pattern sets in, more unstable too.
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.
