Arctic chill Monday; Tracking several rounds of snow

This is an archived article and the information in the article may be outdated. Please look at the time stamp on the story to see when it was last updated.

There is a good chance Monday morning will be the coldest morning so far this season.   Arctic air has been spreading in to central Indiana Sunday afternoon and will be around for at least another 36 hours.

Temperatures will likely drop down to near 0° if not slightly below.

DMA Tonight Low Temperature

Forecast low temperatures for Monday morning.

One thing that will help keep temperatures from plunging further, wind.  Winds are forecast to stay up from the northwest shifting to the west at 9 to 15mph.  However, this will also cause wind chills to drop to -20° to -8° Monday morning.

Don’t expect much of a warm-up Monday, even with ample sunshine.  Highs will only be in the single digits to middle teens.

Forecast high temperatures for Monday.

With the wind factored in, the wind chill temperature will range from -4° to 1°.  Bottom line, bundle up overnight and Monday.

CLIPPER COMING TUESDAY NIGHT IN TO WEDNESDAY

We are tracking another clipper that will dive southeast through the Midwest.  This clipper might have a little more teeth to it than last week’s clipper.

Energy that will develop the clipper is just moving onshore in the northwest United States/southwest Canada Sunday evening.

They system will dive through the central U.S. Tuesday and snow will begin to break out in Iowa and Missouri Tuesday evening.

The clipper will keep moving southeast, arriving in Indiana late Tuesday night or early Wednesday morning, spreading snow across central Indiana.

It is still a little early to be talking specifics as to snow amounts, but at this time, it does appear a 2″ to 4″ band of snow will be possible from Missouri to Illinois and Indiana.

The exact track and how much moisture will be available is still to be set in stone.  We will continue to look over data and make adjustments to the forecast.

LATE WEEK SOUTHERN STORM

Computer models continue to hint at a late week storm that bares watching.  They started hinting at it last week and continue to show it.  So something must be there.

There is still a spread in track of the storm.  One computer model suggests it travels closer to the gulf coast.  Two other suggest it passes south of Indiana – taking a track from Oklahoma City to Memphis to Nashville, TN.  Often times, a heavy band of snow is possible 75-100 miles north/northwest of the track of the surface low pressure.

Stay tuned…
