Another Active Week
Hello and happy Monday everyone – hope all is well as we enter the first full week of March. Tomorrow is Fat Tuesday and the Mardi Gras celebration in New Orleans. After an active weekend in the deep south and lingering early today across the northeast, we are looking for more of the same this week. Another strong low pressure system will move into the Plains tonight/AM Tuesday. This classic spring storm is going to spread heavy snow from the Central Plains to the Upper Mississippi Valley through Wednesday and touch off strong to severe storms across the Lower Mississippi Valley on east through the Tennessee Valley and the southern Gulf Coast states through that time as well. Heavy rain will lift north into already waterlogged areas of the Mississippi and Ohio River Valleys keeping the flood threat high.
Clash of Seasons
We can track the vigorous low pressure systems as it lifts from the Great Basin… These storms are sometimes called “Texas Hookers” – as they dig through the Great Basin and loop up to the Midwest/Great Lakes Region, they gobble up copious amount of moisture from the Gulf of Mexico and spread it north. If temperatures are cold enough, it can produce heavy snow on the north/northwest flank of the system. The trailing cool front is cause for concern too as is whips up severe storms and heavy rain through the lowers third or two thirds of the nation.
Watches & Warnings
Currently, the National Weather Service has issued winter weather headlines from the Central Rockies to the Upper Midwest. A few locations in the Rockies could get up to 10″ or 20″ where a few locations in the Plains or the Upper Midwest could get up to 10″. Another 1″ to 3″ of locally heavy rain will keep the flood threat high through the rest of the week. In fact, the recent heavy rains overwhelmed a levee, which gave way over the weekend in Daviess county, IN – read more HERE: http://m.courierpress.com/news/2011/mar/06/broken-levee-daviess-county-ind/

How Much Snow?
Here’s a graphical output of how much snow to expect through the next few days from the Rockies to the Upper Midwest/Great Lakes.
The severe threat this week looks decent. PM Tuesday and again PM Wednesday – both days feature a SLIGHT RISK of severe weather. See the images below for specific locations and keep up to date with local forecasts in your area where severe weather may threaten this week.
Tuesday Severe Potential
Wednesday Severe Threat
This is the 5 day precipitation forecast – note the heavy precipitation amount through the Tennessee and Ohio River Valleys up to 3″ or 4″ in spots. Again, flooding is going to be a big concern in locations that are already experiencing high water issues now.
That’s all for today – thanks for tuning in and check back again tomorrow for more weather updates.
