THE MID LEVEL PATTERN PREVAILS AS GOES WATER VAPOR IMAGERY AND RAP
ANALYSIS STILL INDICATE A BROAD TROUGH ENCOMPASSING A GREAT PORTION OF
NORTH AMERICA. THE CLOSED LOW HAS NOW MOVED TO NEWFOUNDLAND AND
LABRADOR WITH A WEAK/BRIEF RIDGE OVERHEAD AND A MULTITUDE OF
EMBEDDED WAVES OVER THE CANADIAN PRAIRIE. BENEATH IT A DRY AND COLD
AIRMASS ACCOMPANIES THE 1043MB HIGH PRESSURE OVER THE MIDWEST AS
LATEST SPC MESOANALYSIS INDICATES TEMPS OF -24C TO -25C AND PWATS OF
~0.05", BOTH BELOW THE 10TH PERCENTILE OF NAEFS CLIMATOLOGY. WITH
LIGHT WINDS AND CLEAR SKIES ACROSS MUCH OF THE CENTRAL AND INTERIOR
WEST, RADIATIVE COOLING PROCESSES HAVE ALLOWED TEMPS TO DROP DOWN TO
-10 TO -20 SO FAR THIS MORNING, YIELDING WIND CHILLS OF -30 TO -40.
MAINTAINED EXTREME COLD WARNINGS THROUGH 10 AM EST AS IMPROVEMENT
HOLDS OFF UNTIL MID MORNING AND ADDITIONAL COOLING DOWN TO -30 IS
EXPECTED INTERIOR WEST.
GIVEN THE COLD TEMPS ALOFT, LAKE EFFECT SNOW SHOWERS CONTINUE WITH A
NEAR SURFACE DGZ AND INVERSION HEIGHTS AROUND 5KFT. WITH THE DRIER
SNOW TYPE, ADDITIONAL ACCUMULATIONS WILL BE LIMITED (UP TO 3
INCHES), ESPECIALLY AS HIGH PRESSURE SETTLES SOUTH AND SHIFTS LOW
LEVEL WINDS OUT OF THE WEST TO SOUTHWEST THROUGH THIS MORNING. THIS
EVENTUALLY LIFTS SHOWERS AWAY FROM THE UP. THE PRIMARY FOCUS WAS ON
LOWER VISIBILITIES DOWN TO 1/2 MILE AT TIMES THROUGH THE MORNING
HOURS. DOWNGRADED WINTER STORM WARNINGS TO WINTER WEATHER ADVISORIES
AND EXTENDED THE ADVISORIES OUT UNTIL 10 AM EST. DROPPED NORTHERN
SCHOOLCRAFT COUNTY AS IMPACTS PRIMARILY WILL BE FOCUSED NEAR LAKE
SUPERIOR DUE TO THE STABLE LOW LAYERS WEAKENING LAKE EFFECT SHOWERS
AS THEY MOVE ONSHORE. OTHERWISE TEMPS WARM UP INTO THE SINGLE DIGITS
ABOVE FOR MOST THIS AFTERNOON SAVE FOR JUST BELOW 0 FAR WEST.
HIGH PRESSURE, DRIER AIR, AND LIGHT WINDS HAVE AN INFLUENCE ON THE
TEMPS ONCE AGAIN TONIGHT. FORECASTED CONDITIONS WALK THE LINE WITH
NEEDING COLD WEATHER ADVISORIES AS WINDS BEING NEAR CALM PREVENT
CONCERNING WIND CHILLS FOR MANY, BUT INTERIOR TEMPS BETWEEN -10 AND -
25 ARE EXPECTED BY EARLY SUNDAY MORNING. TEMPS ON SUNDAY ONCE AGAIN
WARM UP INTO THE SINGLE DIGITS ABOVE TO LOW TEENS EAST. LAKE EFFECT
SNOW SHOWERS RETURN OUT OF THE NORTHWEST AS HIGH PRESSURE OVERHEAD
WEAKENS DUE TO A LOW PRESSURE TRACKING NORTHEAST ALONG THE ATLANTIC
COAST. LES 12 HOUR TOTALS OF UP TO 1-3 INCHES ARE EXPECTED OVER THE
NORTHWEST WIND SNOWBELTS SUNDAY AND SUNDAY NIGHT. A SLIGHTLY WARMER
AIRMASS BRINGS A BIGGER DGZ PRESENCE, RAISING SLRS A BIT AND
PRESENTING LESSER VISIBILITY CONCERNS.
LES LIFTS AWAY FROM LAKE SUPERIOR ON MONDAY AHEAD OF A CLIPPER
SYSTEM FOR MONDAY NIGHT INTO TUESDAY. WHILE MOISTURE CONTINUES TO BE
UNIMPRESSIVE, SOME WIDESPREAD LIGHT SNOW UP TO 0.5" IS POSSIBLE
(~30% CHANCE) WITH HIGHER AMOUNTS WHERE LAKE ENHANCEMENT OCCURS.
TRAILING LAKE EFFECT SNOW IS EXPECTED AS A MID LEVEL WESTERN RIDGE
KEEPS NORTHWEST FLOW PERSISTENT OVER THE REGION. MODEL AGREEMENT
QUICKLY FALLS APART NEXT WEEK REGARDING TIMING OR TRACK OF ANY
ADDITIONAL SHORTWAVE/CLIPPER SYSTEMS, BUT NEAR TO BELOW NORMAL TEMPS
PERSIST (5F TO 10F BELOW NORMAL). HIGHS IN THE SINGLE DIGITS ABOVE
TO MID TEENS AND LOWS IN THE SINGLE DIGITS ABOVE/BELOW ARE FORECAST.
