Happy Spring 2024

\"\"

7:15 AM ET Temperature Analysis: Chilly across the Southeast this morning with some areas dipping into the upper-20s and lower-30s across Alabama and around Columbus, Georgia. Also in the 30s to Gainesville, Florida.

Wednesday Afternoon High Temperatures

\"\"

Beautiful and mild spring day across the southern U.S. with 60s and 70s lining up from the Ohio Valley southward.

Still chilly across the Midwest and Great Lakes in the 20s for highs in Northern Michigan \u2014 cold enough for scattered Lake Effect snow showers.

Lake Enhanced Snow Showers with Low Pressure System

\"\"

The swirl over Quebec is a rather strong low pressure system for a \u201cClipper\u201d around 990 mb. The circulation is dragging colder Canadian Arctic behind it + enough moisture + [warmer] Great Lakes enhancement = accumulations

The system re-intensifies over Maine later on Thursday!

Snowfall Next 72-Hours

\"\"

All added up during the next 72-hours will see up to a foot of new snow in Michigan!

The next \u201cClipper System\u201d will race across the northern tier of states dropping a nice blanket of up to 6-inches from Montana, through Minneapolis into Milwaukee.

Next 10-days Weather Pattern: Several Storm Systems

\"\"

Thursday: Clipper system over Northeast and Maritime Canada deepens with significant snowfall in Maine

Friday into Saturday: area of low pressure skirts along Gulf Coast = heavy rain for Florida,

Saturday into Monday: East Coast low develops and intensifies with heavy rain in Mid-Atlantic and Northeast.

Monday: Powerful central plains into Midwest winter storm

Minneapolis Snowfall

\"\"

Potential for major snowfall centered on Minneapolis over the next 7-10 days from a powerful winter storm Monday

Blend of Models: 10 Day Snowfall Forecast

\"\"

The Blend of Models is a collection of major global weather models and their ensembles so it is typically rather smooth. But not the upcoming 10-day forecast!

That is over 30\u201d centered upon Minnesota with a large area of more than 1-foot of snowfall accumulations across the Midwest into the Great Lakes. Amazing map during the last 10-days of March.

Blend of Models Temperatures Next 8-Days

\"\"

Temperatures remain cold enough for snowfall mainly north of Interstate 80 during the next 8-days even during the daytime. With weather systems tracking through, we\u2019ll see warmer air ahead of fronts, however.

Overall, the last 10-days of March will be seasonably cool without a major heat wave except I suppose for Florida in the 80s.

WPC 7-Day Precipitation Forecast

\"\"

The next week will also be quite wet with this progressive weather pattern.

2.1\u201d of QPF in Minneapolis to fall mostly as snowfall. Large area of 2-3\u201d from Houston into the Southeast and up the Eastern Seaboard including DC, NYC, and Boston.

ECMWF EPS 10 Day Temperature Anomaly

Days 1-5 | March 20 - March 24

\"\"

Days 6-10 | March 25 - March 29

\"\"

Snowfall Probability over 6-inches | Next 15-days

\"\"

Amazing to see such high probability of at least 6-inches of snowfall in late March into early April across the Lower 48 outside of the mountain west \u2014 evidence of the influence of colder Canadian Arctic air.

Median Snowfall Accumulation | Next 15-days

\"\"

The EPS median snowfall is 12-18\u201d centered upon Minnesota and Maine!

Huge multi-feet accumulations for the Cascades and Sierra as winter continues full-tilt in the Western U.S. into April.
