While the East remains relatively quiet until the end of the week, unsettled weather will continue to the West. Rain and snow on the West Coast is likely to stick around until Friday, and developing rain and thunderstorms is unfortunately expected to exacerbate historical flooding across the Central US well into the weekend.
Welcome to the Tuesday edition of your Morning Briefing, where we give you a quick rundown on everything you need to know weather-wise, every weekday morning. Let’s jump right in.
West Coast Rain and Snow All Week:
- After an initial round of rainfall yesterday, the West Coast can expect a few days of heavy rain and mountain snow following a cold frontal passage Wednesday.
- Periods of moderate to heavy rain will impact parts of the coast Wednesday and Thursday, as heavy downpours can cause sudden slowdowns and road/flash flooding.
- The heaviest rainfall will be over Northern California early Wednesday morning, where places north of Highway 20 could receive upwards of 2″ of rain by the storm’s end. Possible thunderstorms would increase local totals as well.
- Heavy mountain snow above 4000 ft over the Sierras will also impact Northern CA this week, with up to 10″ possible over 4500 ft, and up to 2′ possible over 7000 ft. Mixed with high wind gusts around 60 mph, and you get blizzard conditions that could cause mountain pass closures and near impossible traveling conditions to higher elevations.
Exacerbated Flooding for the Midwest and Mississippi Valley:
- Cyclone development over the Rockies late week will pack a heavy punch for the Midwest, continuing the already record flooding that has plagued the region for over a week.
- Flood advisories remain in affect for many rivers across most Midwestern states, as snowpack melt and ice jams keep river levels in minor to major flood stages.
- Later this week, flooding will only get worse as moderate to heavy rain, along with possible thunderstorms, exacerbate the situation. Flooding is expected to then continue well into next week, leaving many communities without the opportunity to even begin recovery.

Mostly Quiet Weather to the East:
- A chilly start to the week will moderate across the Eastern third of the US as rain showers in the Southeast taper off today. With mostly clear skies up and down the coast, much of the East can expect a beautiful, quiet week to start Spring.
- High pressure will begin to build aloft, followed by a mostly zonal flow over the East coast. This will allow warm, dry air to come into the region from the West for the majority of the week.
- The next storm to keep an eye out for will be Friday, when the same storm that will keep flooding in the Midwest will give the East Coast a soak.
