Storm Center Update - Saturday AM

Our stretch of cool weather and clouds continues for many today.  While light rain falls in far SW South Dakota, it’s feeling like -20° in Sisseton this morning.  With a snowpack and north breeze, the northeast will have a tough time getting out of the teens today.  Sioux Falls topped out near 30 this morning but most of the day will be colder.  If you are heading out to St. Patrick’s Day festivities, you’ll want to bundle up. In this setup with overcast skies it is not uncommon to see flurries, which could occur periodically throughout the day.

Showers in the west should remain fairly light.  They will progress northwards into the Black Hills today, giving Rapid City a decent chance at upsloping moisture.  Another system starts to move in this evening.  This will bring a widespread chance of moisture along with much stronger winds.  There is a Winter Storm Watch for North Dakota, where conditions should really deteriorate tomorrow.  There is also a High Wind Watch for much of West River.  The initial push of warmer air will bring a chance of isolated rain and snow showers to central South Dakota late tomorrow morning and during the afternoon.  This will be followed by the better chance of moisture late tomorrow, during the evening and overnight hours.  The best chance for Sioux Falls and Aberdeen is after dark.  Most in the southern half of KELOLAND  should see lighter rain showers while those in the north are awaiting light snow showers, generally less than a few inches.  Also, if skies clear after this, you might be able to witness the Aurora outbreak to our north. 
Winds will really ramp up tomorrow and tomorrow night.  Gusts in the Black Hills could top 50 mph at times. 
After the brief Sunday warm-up, it’s a return to clouds and cold.  It looks like the best day for sunshine will be Wednesday but even then, the west will have partly cloudy skies.  The next round of shower chances comes Thursday into Friday.
