Weather Alert in Minnesota

Recent Locations: Sanford, FL Clark, SD Conger, MN

Winter Storm Warning issued April 2 at 6:59AM CDT until April 2 at 10:00AM CDT by NWS Twin Cities/Chanhassen MN

AREAS AFFECTED: Washington; Scott; Dakota; Le Sueur; Rice; Goodhue

DESCRIPTION: ...MESSY SPRING SYSTEM BRINGS FREEZING RAIN, SLEET, AND SNOW THROUGH THIS MORNING... .Western and central Minnesota will experience mainly slushy wet snow with accumulations of 2 to 4 inches, meanwhile rain is favored in southern and southeastern Minnesota. In between the snow and rain, a messy wintry mix of sleet and freezing rain will result in ice accumulations and slippery travel. There is still a moderate degree of uncertainty regarding ice accumulation amounts, due to temperatures being very close to freezing and a fluctuation of only a degree or two likely having a large impact on final amounts. The greatest impacts from icing and freezing rain will occur over western Wisconsin and east-central Minnesota, with accumulations up to a quarter inch in Minnesota and a few tenths of an inch in Wisconsin. Power outages are possible due to icing of power lines in addition to gusty winds, and slippery to impossible travel will occur where ice accumulates. Slow travel from wet slushy snow is expected in western and central Minnesota. * WHAT...Heavy mixed precipitation. Additional snow accumulations up to one inch, sleet accumulations up to one tenth of an inch, and ice accumulations up to one tenth of an inch. * WHERE...Dakota, Scott, Washington, Le Sueur, Rice, and Goodhue Counties. * WHEN...Until 10 AM CDT this morning. * IMPACTS...Roads, and especially bridges and overpasses, will likely become slick and hazardous. Significant ice accumulation on power lines and tree limbs may cause widespread and long-lasting power outages. Plan on slippery road conditions. The hazardous conditions will impact the Thursday morning commute.

INSTRUCTION: If you must travel, keep an extra flashlight, food, and water in your vehicle in case of an emergency. Call 5 1 1 or visit 511mn.org for road conditions. Persons should consider delaying all travel. If travel is absolutely necessary, drive with extreme caution. Consider taking a winter storm kit along with you, including such items as tire chains, booster cables, flashlight, shovel, blankets and extra clothing. Also take water, a first aid kit, and anything else that would help you survive in case you become stranded.

A contrail is an artificial cloud, created by the passing of an aircraft.

Contrails form because water vapor in the exhaust of aircraft engines is suspended in the air under certain temperatures and humidity conditions. These contrails are called exhaust contrails.

Another type of contrail can form due to a temporary reduction in air pressure moving over the plane's surface, causing condensation. These are called aerodynamic contrails.

When you can see your breath on a cold day, it is also because of condensation. The reason contrails last longer than the condensation from your breath is because the water in contrails freezes into ice particles.

Cumulus clouds are fluffy and textured with rounded tops, and may have flat bottoms. The border of a cumulus cloud is clearly defined, and can have the appearance of cotton or cauliflower.

Cumulus clouds form at low altitudes (rarely above 2 km) but can grow very tall, becoming cumulus congestus and possibly the even taller cumulonimbus clouds. When cumulus clouds become taller, they have a greater chance of producing precipitation.
