Major late season winter storm


Recommended Posts

no ice in brookings, air temperature too low, we have what looks to be about 2 inches of sleet/snow here. NOAA's math adds up to 17 inches for Brookings. It's still sleeting with the snow here though, keeping down the totals.. but it shouldn't be hard to hit 3 inches by nightfall.

 

  • This Afternoon Snow. High near 25. Windy, with a north northeast wind 25 to 30 mph, with gusts as high as 40 mph. Chance of precipitation is 90%. Total daytime snow accumulation of around 3 inches.
  • Tonight Snow before 2am, then snow and sleet between 2am and 4am, then snow after 4am. Low around 25. Blustery, with a north northeast wind 20 to 25 mph, with gusts as high as 35 mph. Chance of precipitation is 100%. New snow and sleet accumulation of around 5 inches.
  • Wednesday Snow. High near 30. Blustery, with a north northeast wind around 20 mph, with gusts as high as 30 mph. Chance of precipitation is 90%. New snow accumulation of around 3 inches.
  • Wednesday Night Snow. Low around 24. Blustery, with a north northeast wind 15 to 20 mph, with gusts as high as 30 mph. Chance of precipitation is 90%. New snow accumulation of around 5 inches.
  • Thursday Snow likely. Cloudy, with a high near 30. North northeast wind around 15 mph. Chance of precipitation is 70%. New snow accumulation of around an inch possible.

 

 

Sioux Falls got the ice.

Not that many outages reported but a lot are probably at work.

 

SIOUX FALLS, SD -

Xcel Energy says it's working as fast as possible to restore power to Sioux Falls residents in the wake of the spring ice storm.

Trees and power lines have been coated with a heavy layer of ice, creating power problems.

Xcel says it's restored service to about 5,000 people. But, an estimated 4,000 remain without power as of 10 a.m.

Crews have been brought in from Minnesota to help get the power back on. But, they say, the damage to the system is extensive and some customers may not have power until Wednesday afternoon.

Xcel says power outages have been reported in other areas as well. They're working in several South Dakota communities to get power back on.

 

 

Here's some south dakota webcams

Surprisingly it looks like we have more snow/sleet accumulation than watertown, the storm's first segment has followed the GFS and GEM route and not the NAM route.

 

More webcams that update more sporadically...

Deadwood and Lead are always good for some excellent snow totals.

I read Hot Springs, SD didn't do too bad either. 28.2" at 8am.

 

Lead and Deadwood are in a high area facing to the northeast, so they really get hammered good in this type of setup.

 

Climate records smashed in the area.

Dang, what a late season storm. Just rain here in lower MI. 3.16" so far since it all started. Only a high of 37 today, but not as cold as elsewhere. I'll be anxious to ses some of the webcams on my site in the morning of upper Michigan and how much snow they get. Boy, I hope this isn't a sign of the summer ahead. lol

ATTN WFOS...APX...MQT...GRB...DLH...ARX...MPX...

ATTN RFCS...NCRFC...

.

EVENT...INCREASING SNOW COVERAGE AND RATES ACROSS N WI/N LOWER MI AND

THE UP OF MI/FAR NE MN.

.

SATELLITE ANALYSIS AND TRENDS...IR ANIMATION IS BEGINNING TO SHOW WHAT

APPEARS TO BE A REFORMATION OF THE COMMA HEAD NEAR THE WELL DEFINED

DEFORMATION ZONE OVER N WI/THE UP OF MI/FAR NE MN. THIS IS LIKELY IN

RESPONSE TO THE APPROACH OF THE PRIMARY MID/UPPER LEVEL CIRCULATION

CENTER NEARLY COLLOCATED WITH THE SFC LOW, ROTATING TO THE NNE OVER N IA

AS SEEN IN WATER VAPOR IMAGERY AND THE GOES RGB AIRMASS PRODUCT. WATER

VAPOR IMAGERY IS ALSO PICKING UP ON ANOTHER DISTURBANCE MOVING TO THE

EAST OVER S IA AND YET ANOTHER RIDING THE JET NORTHWARD FROM E MO INTO

IL WHICH IS ALSO AIDING IN THE OVERALL LIFT FOR THE REGION. ANALYSIS IS

INDICATING MOISTURE BEING PULLED FROM THE MAIN BAROCLINIC REGION BACK

TO THE NW WHICH IS NOW EVEN VERIFIED BY THE COMPOSITE RADAR ANIMATION

SHOWING THE PRECIP SHIELD MOVING/EXPANDING TO THE N AND NW ACROSS N LOWER

MI/N WI AND THE UP OF MI. AT THIS TIME, REGIONAL METAR OBSERVATIONS ARE

INDICATING ONLY LIGHT SNOW/MIXED PRECIP IN THIS REGION BUT WOULD EXPECT

THAT TO CHANGE OVER THE NEXT COUPLE OF HOURS AND BEYOND.

.

SHORT TERM OUTLOOK VALID 0100-0700Z...MEDIUM CONFIDENCE FACTOR IN SHORT

TERM OUTLOOK...BASED ON THE SATELLITE/RADAR TRENDS, EXPECT SNOW TO

INCREASE IN COVERAGE AND INTENSITY OVER THE NEXT 6 HOURS WITH AT LEAST

SOME GREATER COVERAGE OF MODERATE SNOW TO LOCALLY HEAVY SNOW OVER FAR

N LOWER MI/THE UP OF MI/N WI AND POSSIBLY FAR NE MN, ROUGHLY ALIGNED

WITH THE HIGH PROBABILITY OF GREATER THAN 4" IN THE DAY 1 WPC SNOW

ACCUMULATION GRAPHIC. SNOW RATES SHOULD INCREASE TO AT LEAST .5"/HR TO

POSSIBLY APPROACHING 1.0"/HR WITH THE POTENTIAL OF EVEN HIGHER LOCALIZED

RATES DEVELOPING TOWARD THE MIDDLE TO END OF THE OUTLOOK PERIOD ONCE

THE BETTER DYNAMICS/FRONTOGENETIC FORCING KICKS IN.
