Mom was always right.
Among mom's most classic advice and admonitions? "Would you jump off a bridge just because somebody else did it?" And "Wait until Memorial Day weekend to plant those petunias and geraniums!"
Thanks, mom.
Freeze warnings and frost advisories are flying into Tuesday morning for a big chunk of the Upper Midwest. Temperatures drop below freezing in the Red River Valley, and frost will nip as close to the Twin Cities as the far western metro suburbs Tuesday morning.

Moderating trend this week
The inbound high pressure system clears our skies, and sunshine returns this week. That helps temperatures moderate. A dry and increasingly milder forecast kicks in as the week unfolds.
"Typical" Memorial Day weekend
The typical Memorial Day weekend in Minnesota? A 50/50 mix of anticipation and disappointment.
Climatologically speaking, Memorial Day weekend is the wettest of the "Big 3" summer holiday weekends. It also has the best chance of severe weather. The statistical peak of severe weather season as defined by the number of severe weather reports flowing into the Twin Cities National Weather Service falls in June between Memorial Day and the Fourth of July.
Stormy days begin to fall rapidly as we move into mid and late summer. Yes, Labor Day is often your best bet for tranquil summer holiday weather in Minnesota.
True to form, this weekend looks like a mix of decent outdoor weather, and rainy hours. My weather advice? Front load the weekend and include Friday if possible. That looks like the best day of the upcoming weekend zone.
