Storm Team 4Cast for 2/6/13
Thursday's morning commute could bring more snow
MILWAUKEE - The pattern shifted to a steady west to northwesterly jet stream last week and so far it has produced four Alberta Clipper type storms and snowfalls from a trace to two inches every day since last Wednesday.
The fifth low pressure system from southern Canada moves in tonight with the chance for a couple of inches of snow by the morning commute Thursday and a couple more during the day.
Wednesday will break the string of snowy days with plenty of sunshine and high temperatures warming to near the freezing mark in Milwaukee.
On this date in 2008 a major snowstorm hit southeast Wisconsin with a new daily record snowfall of more than eleven inches and nearly eighteen inches north and west of the city. The low pressure system that brought this much snow to Wisconsin had to tap a source of moisture to produce that snow, and those are called Panhandle Hooks or southwestern low pressure systems.
They need a southwestern jet stream and cold air in place across the central and northern Plains and Midwest to flourish. They originate near the panhandle region of Texas and Oklahoma, travel northeast toward northern Illinois while picking up tons of atmospheric moisture from the Gulf of Mexico.
These storms produce the greatest snowfalls and strongest blizzards from Missouri to Michigan.
