...BLIZZARD CONDITIONS TO WIND DOWN TODAY ACROSS THE NORTH-CENTRAL  
U.S., LEAVING UNSEASONABLY COLD TEMPERATURES THROUGH THE WEEKEND...  
 
...SEVERE THUNDERSTORMS AND HEAVY RAIN EXPECTED FROM EASTERN TEXAS  
INTO THE LOWER MISSISSIPPI VALLEY ON SATURDAY...  
 
THE STRONG STORM SYSTEM RESPONSIBLE FOR BRINGING 1-2 FEET OF SNOW  
TO PORTIONS OF NEBRASKA AND SOUTH DAKOTA WILL LIFT NORTH INTO  
CANADA TODAY WHILE WEAKENING. HOWEVER, GUSTY WINDS WILL REMAIN A  
CONCERN ALONG WITH FALLING SNOW THIS MORNING REDUCING VISIBILITIES  
AND CREATING BLIZZARD CONDITIONS FROM EASTERN SOUTH DAKOTA INTO  
SOUTHEASTERN NORTH DAKOTA AND WESTERN MINNESOTA. ADDITIONAL  
SNOWFALL AFTER SUNRISE WILL BE GREATEST ACROSS NORTHEASTERN  
MINNESOTA WHERE AN ADDITIONAL 2-4 INCHES IS EXPECTED, WITH LIGHTER  
ACCUMULATIONS ELSEWHERE. HIGH TEMPERATURES FOR TODAY WILL BE A  
SOLID 20 TO 30 DEGREES BELOW MID-APRIL AVERAGES FROM NEBRASKA INTO  
SOUTH DAKOTA, MINNESOTA AND NORTHWESTERN IOWA WITH A GRADUAL  
MODERATION INTO SUNDAY BUT REMAINING BELOW AVERAGE.  
 
THE OTHER BIG STORY WILL BE TIED TO A SPRING STORM FORECAST TO  
IMPACT PORTIONS OF THE SOUTHERN U.S. FOR THE WEEKEND. AN UPPER  
LEVEL DISTURBANCE WILL PASS OVER ARIZONA AND NEW MEXICO TODAY  
BRINGING HIGHER ELEVATION SNOW TO THE FOUR CORNERS STATES. THE  
GREATEST ACCUMULATIONS SHOULD FALL IN THE SANGRE DE CHRISTO  
MOUNTAINS OF NORTHERN NEW MEXICO WHERE ROUGHLY 6-12 INCHES ARE  
FORECAST. LOW RELATIVE HUMIDITIES AND GUSTY WINDS ACROSS PORTIONS  
OF WEST TEXAS INCLUDING BIG BEND NATIONAL PARK WILL AGAIN LEAD TO  
FAVORABLE CONDITIONS CONDUCIVE TO THE SPREADING OF WILDFIRES  
TODAY. A LITTLE FARTHER EAST, RAIN WILL DEVELOP TONIGHT ACROSS  
CENTRAL/NORTHERN TEXAS INTO OKLAHOMA AS THE UPPER LEVEL SYSTEM  
TRACKS EAST. ALSO, SOME WET SNOW IS LIKELY FOR THE TEXAS AND  
OKLAHOMA PANHANDLES SATURDAY MORNING AS TEMPERATURES FALL INTO THE  
30S.  
 
HEAVY RAIN WITH THE POSSIBILITY OF FLASH FLOODING WILL SET UP FROM  
THE ARKLATEX INTO THE MIDDLE AND LOWER MISSISSIPPI VALLEY ON  
SATURDAY WHERE 2-4 INCHES OF RAIN WILL BE POSSIBLE. THERE IS ALSO  
A MODERATE RISK OF SEVERE THUNDERSTORMS (VIA THE STORM PREDICTION  
CENTER) IN PLACE FROM PORTIONS OF FAR EASTERN TEXAS INTO NORTHERN  
LOUISIANA, SOUTHERN ARKANSAS AND FAR WEST-CENTRAL MISSISSIPPI. ALL  
SEVERE HAZARDS WILL BE POSSIBLE INCLUDING TORNADOES, LARGE HAIL  
AND STRAIGHT LINE WINDS. LOCALLY HEAVY RAIN WITH EMBEDDED  
THUNDERSTORMS WILL TRANSLATE EAST DURING THE DAY ON SUNDAY TOWARD  
THE EAST COAST WHERE TEMPERATURES WILL REMAIN A LITTLE ABOVE  
AVERAGE.  
 
ACROSS THE PACIFIC NORTHWEST, A BRIEF LULL IN UNSETTLED WEATHER  
WILL OCCUR LATE TODAY AND TONIGHT BEFORE THE NEXT STORM SYSTEM  
REACHES THE COAST EARLY SATURDAY MORNING. THIS NEXT SYSTEM WILL BE  
A QUICK-MOVER BRINGING MODEST AMOUNTS OF RAIN AND HIGHER ELEVATION  
SNOW TO INTERIOR PORTIONS OF THE NORTHWEST FOR SATURDAY AND  
SATURDAY NIGHT.
