The Weather Man Podcast, I talk about weather!

Heavy lake-effect snow downwind from Lakes Erie and Ontario; snow over
the Southwest/Southern Rockies.
There is a Slight Risk of excessive rainfall over parts of the Central
Gulf Coast
There is a Marginal Risk of severe thunderstorms over parts of the
Central Gulf Coast and Florida.
A front extending from Maine over the Western Atlantic, coming back
onshore over the Southeast, and stretching across the Gulf Coast on Sunday
will slowly move southward across Florida by Monday evening. A wave of low
pressure on the boundary over the Central Gulf Coast moves eastward to the
Southeast by Monday. The circulation around the low will pull moisture off
the Gulf of Mexico, aiding in the production of showers and thunderstorms
with heavy rain over parts of the Central Gulf Coast. Therefore, the WPC
has issued a Slight Risk (level 2/4) of excessive rainfall over parts of
the Central Gulf Coast through Monday morning. The associated heavy rain
will create mainly localized areas of flash flooding, with urban areas,
roads, and small streams the most vulnerable.
In addition, the thunderstorms will be strong to severe along parts of the
Central/Eastern Gulf Coast. Therefore, the SPC has issued a Marginal Risk
(level 1/5) of severe thunderstorms over parts of the Central/Eastern Gulf
Coast through Monday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts, and
a minimal threat of tornadoes and hail.
On Monday, the threat of excessive rainfall ends over the Gulf Coast.
However, the threat of showers and strong to severe thunderstorms moves
over Florida. Therefore, the SPC has issued a Marginal Risk (level 1/5) of
severe thunderstorms over parts of Florida from Monday into Tuesday
morning. The hazards associated with these thunderstorms are frequent
lightning, severe thunderstorm wind gusts, and hail, with a minimal threat
of tornadoes. By Tuesday, the showers and thunderstorms move off the
southern tip of Florida as the front moves offshore.
Meanwhile, upper-level energy over the Upper Midwest into the Northeast
will aid in creating lake-effect snow downwind from the Great Lakes, with
moderate to heavy snow downwind from Lakes Erie and Ontario through
Tuesday evening. Additionally, moderate snow will develop over the higher
elevations of the Northeast, with snow showers over parts of the Ohio
Valley and the Central Appalachians through Tuesday afternoon.
Moreover, an upper-level low over the Four Corners Region will produce
snow and lower-elevation rain over parts of the Southwest and Southern
Rockies, lingering through Tuesday.
Furthermore, a second front moving south and eastward from Central Canada
will move over parts of the Northern Plains/Upper Mississippi Valley on
Monday afternoon, moving to the Great Lakes by Tuesday. The system will
produce light snow over parts of the Upper Mississippi Valley overnight
Monday and of the Upper Great Lakes on Tuesday.
