A slow moving storm system has been stuck over the Central Rockies over the past few days, kicking out nearly 2ft to 4ft of snow in the mountains. Denver, CO saw a high temperature of 75° on Tuesday and woke up to 4" of snow on Friday!
This storm will finally make a move east; showers and rumbles of thunder will begin to move into southern Minnesota by the afternoon and spread through northern part of the state through the evening. Some models are suggesting nearly 1" rain through the end of the weekend, which will help moderate drought that now encompasses nearly 92% of the state.
SUNDAY: Wet start. Rain tapers by PM. High: 58. Winds: SE turning NW 10.
MONDAY: Breezy & cooler with a rain/snow mix up north. Wake-up: 40. High: 50
TUESDAY: A few AM flakes. Still breezy and cool. Wake-up: 33. High: 48
WEDNESDAY: More sun, a little warmer. Wake-up: 33. High: 51
THURSDAY: Breezy with sunshine. Wake-up: 35. High: 54
FRIDAY: Breezy. Bright sunshine. Wake-up: 35 High: 54
This Day in Weather History
1965: The Mississippi River crested at St. Paul 4 feet above the previous record. High water records were set all the way down to Missouri in later days. There was little loss of life due to early warnings.

Minneapolis Temperature Trend
After an incredibly mild Friday, temperatures will take a slide through the weekend/early next week into more March-like weather. Extended forecasts suggest slightly cooler than average temperatures continuing through much of the rest of the month...
Saturday Weather Outlook
Weather conditions on Saturday will sour through the day. High temperatures will fall from the 70s on Friday to the 60s on Saturday. Winds will also increase out of the E/SE 10-20mph.
Saturday Weather Outlook
The slow moving storm system that has been impacting the Plains over the past few days will begin moving into our region over the weekend. Rain will start moving into the southern part of Minnesota around midday and spread through the rest of the region through the evening. Sunday looks a bit soggy too.
The rainfall potential through 7pm Sunday suggests a fairly widespread 0.50" to 1.00" swath across the state. Some of the heaviest appears to be across the southern part of the state.
As of this week, the U.S. Drought Monitor had nearly 92% of the state under MODERATE DROUGHT
Heavy Snow in April
33 commercial vehicles and 12 passenger vehicles is the latest estimate that were involved in one of the three crash sequences along with multiple other vehicles that were not part of an actual crash, but became stranded in the event due to road blockage. 16 motorists were transported by ambulance and 11 motorists were transported by a Laramie County School District bus to Cheyenne Regional Medical Center in Cheyenne, Wyoming. Six of those injured were critical to serious leg or spine injuries. No fatalities were reported from this event.
Speeds too fast for the blizzard conditions and loss of control are being investigated as contributing factors in the crashes that caused a "domino" style chain reaction after the first couple of vehicles lost control.
Agencies that responded were the Wyoming Highway Patrol, Laramie County Sheriff's Office, Albany County Sheriff's Office, Wyoming Office of Homeland Security, Laramie County Fire Districts 1, 2, and 10, AMR Ambulance, F.E. Warren First Responders, Wyoming National Guard First Responders, City of Laramie Fire Department, WYDOT and multiple tow companies from Cheyenne and Laramie. Joint training between all of these agencies and their dispatchers was credited for the rapid response, extrication, treatment and transport of those injured in the event.
Interstate 80 between Cheyenne and Laramie is expected to remain closed into tonight and possibly through the early morning hours of tomorrow (April 17th) as the investigation and cleanup continues through the evening. Weather will hold a strong determining factor for the investigators and cleanup crews as to when I 80 will be ready to reopen. Again, we ask motorists at the road closed gates in Cheyenne and Laramie to please be patient and check for updates at www.wyoroad.info or by calling 1-888-WYO-ROAD (1-888-996-7623)
SEVERE THUNDERSTORMS WITH WIND DAMAGE AND HAIL ARE POSSIBLE SATURDAY
ACROSS MUCH OF CENTRAL AND EASTERN TEXAS EASTWARD INTO LOUISIANA.
THUNDERSTORMS WITH HAIL AND A FEW STRONG WIND GUSTS ARE ALSO
POSSIBLE FROM OKLAHOMA NORTHWESTWARD ACROSS KANSAS INTO NORTHEASTERN
AN UPPER-LEVEL TROUGH IS FORECAST TO MOVE INTO THE SRN HIGH PLAINS
ON SATURDAY AS A SFC TROUGH DEVELOPS ACROSS WCNTRL TX EXTENDING SWD
INTO THE RIO GRANDE VALLEY. A LOW-LEVEL JET IS FORECAST AT THE START
OF THE PERIOD OVER LA WHERE WIDESPREAD THUNDERSTORM DEVELOPMENT MAY
BE ONGOING. THIS ACTIVITY COULD HAVE A MARGINAL SEVERE THREAT DURING
THE DAY. FURTHER TO THE WEST...THE MODELS SUGGEST A CORRIDOR OF
MODERATE INSTABILITY WILL BE IN PLACE BY AFTERNOON ACROSS SRN AND
CNTRL TX. ALTHOUGH CONVECTIVE COVERAGE IS UNCERTAIN...THE GFS AND
ECWMF SOLUTIONS DEVELOP CONVECTION FROM THE TX HILL COUNTRY SEWD TO
THE TX COAST SATURDAY AFTERNOON.
AROUND 1500 J/KG WITH SFC DEWPOINTS IN THE LOWER 60S F AND STEEP LOW
TO MID-LEVEL LAPSE RATES. IN ADDITION...0-6 KM SHEAR IS 45 TO 50 KT
WITH SOME DIRECTIONAL SHEAR BELOW 850 MB. THIS SHOULD SUPPORT
SUPERCELL DEVELOPMENT WITH LARGE HAIL AND WIND DAMAGE POSSIBLE. IF
THE MORE AGGRESSIVE GFS SOLUTION IS CLOSER TO VERIFYING...THEN AN
ENHANCED SEVERE THREAT MAY DEVELOP ACROSS PARTS OF SRN AND CNTRL TX
SATURDAY AFTERNOON. FURTHER TO THE NORTH ACROSS NCNTRL TX...ENOUGH
INSTABILITY IS FORECAST FOR A SEVERE THREAT. HOWEVER...DEEP-LAYER
SHEAR SHOULD BE WEAKER HELPING TO KEEP THE POTENTIAL FOR HAIL AND
WIND GUSTS MORE ISOLATED.
AN UPPER-LEVEL LOW IS FORECAST TO MOVE EWD INTO THE CNTRL HIGH
PLAINS ON SATURDAY AS A SFC LOW DEEPENS ACROSS THE TX PANHANDLE. A
NARROW CORRIDOR OF INSTABILITY IS FORECAST FROM WRN OK NWWD INTO
WCNTRL KS AND INTO NERN CO. THE AIRMASS SHOULD BECOME UNCAPPED BY
AFTERNOON WITH SCATTERED THUNDERSTORMS DEVELOPING ALONG THIS
CORRIDOR. A FEW CLUSTERS OF THUNDERSTORMS MAY ORGANIZE AND PERSIST
FROM LATE AFTERNOON INTO THE EVENING.
DEWPOINTS NEAR 60 F WITH MLCAPE OF 1000 TO 1500 J/KG. IN
ADDITION...0-6 KM SHEAR IS FORECAST TO BE NEAR 40 KT WITH STEEP
MID-LEVEL LAPSE RATES. THIS SHOULD SUPPORT SEVERE STORMS WITH HAIL
AND STRONG WIND GUSTS POSSIBLE. CELLS THAT CAN DEVELOP IN AREAS
WHERE INSTABILITY IS MAXIMIZED...MAY BE ABLE TO ROTATE AND PRODUCE
LARGER HAILSTONES. FURTHER TO THE NORTHWEST INTO NW KS...SRN NEB AND
NE CO...INSTABILITY IS FORECAST TO BE WEAKER THAN IN THE SRN PLAINS.
HOWEVER...COLD AIR ALOFT AND STEEP LAPSE RATES BENEATH THE
UPPER-LEVEL LOW MAY BE ENOUGH FOR STORMS THAT PRODUCE HAIL.
THUNDERSTORMS WITH WIND DAMAGE AND SEVERE HAIL WILL BE POSSIBLE FROM
EASTERN PARTS OF THE SOUTHERN PLAINS EASTWARD TO THE CENTRAL GULF
COAST STATES ON SUNDAY AFTERNOON. THUNDERSTORMS WITH WIND DAMAGE
POTENTIAL WILL ALSO BE POSSIBLE ACROSS THE MID MISSISSIPPI VALLEY
A BROAD UPPER-LEVEL TROUGH IS FORECAST TO MOVE EWD ACROSS THE SRN
AND CNTRL PLAINS ON SUNDAY AS A COLD FRONT ADVANCES QUICKLY EWD INTO
THE ARKLATEX AND OZARK MOUNTAINS. AHEAD OF THE FRONT...A BROAD WARM
SECTOR IS FORECAST FROM EAST TX EWD INTO THE CNTRL GULF COAST STATES
WHERE MODERATE INSTABILITY SHOULD BE IN PLACE BY AFTERNOON. MODEL
FORECASTS ARE IN FAIRLY GOOD AGREEMENT...DEVELOPING CONVECTION ALONG
A PRE-FRONTAL TROUGH JUST AHEAD THE FRONT AND MOVING THE CONVECTION
EWD ACROSS THE ARKLATEX AND MID MS VALLEY SUNDAY AFTERNOON. NAM
FORECAST SOUNDINGS ALONG THE INSTABILITY AXIS AT 21Z ON SUNDAY FOR
LITTLE ROCK AR AND SHREVEPORT LA SHOW AN IMPRESSIVE THERMODYNAMIC
ENVIRONMENT WITH MLCAPE FORECAST TO BE IN THE 3000 TO 4000 J/KG
RANGE. THIS COMBINED WITH 0-6 KM SHEAR OF 30 TO 40 KT WITH STEEP
LAPSE RATES SHOULD BE FAVORABLE FOR STRONG UPDRAFTS. SUPERCELLS
SHOULD BE CAPABLE OF PRODUCING LARGE HAIL AND WIND DAMAGE. AS STORM
COVERAGE INCREASES DURING THE AFTERNOON...LINEAR DEVELOPMENT MAY
ALSO OCCUR. VEERED WINDS JUST AHEAD OF THE FRONT WITH UNIDIRECTIONAL
WIND PROFILES ABOVE 850 MB COULD BE FAVORABLE FOR AN ENHANCED
WIND-DAMAGE THREAT ESPECIALLY IF A COLD POOL CAN ORGANIZE ACROSS THE
VALLEY...THUNDERSTORM DEVELOPMENT WILL ALSO BE POSSIBLE SUNDAY
AFTERNOON. HOWEVER...LARGE-SCALE ASCENT SHOULD BE LIMITED KEEPING
ANY CONVECTIVE DEVELOPMENT ISOLATED IN NATURE AND CONCENTRATED ALONG
OUTFLOW BOUNDARIES OR ZONES OF LOW-LEVEL CONVERGENCE.
STILL...DEEP-LAYER SHEAR MAY BE STRONG ENOUGH WHICH COMBINED WITH
MODERATE INSTABILITY COULD SUPPORT MARGINALLY SEVERE WIND GUSTS
ACROSS THE REGION.
