FORECAST UPDATE
ISSUED AT 944 AM EST TUE JAN 27 2026
THE FORECAST REMAINS IN RELATIVELY GOOD SHAPE WITH ONLY MINOR
ADJUSTMENTS NEEDED. LATEST SURFACE ANALYSIS DEPICTS A STRONG SURFACE
HIGH CENTERED NEAR THE DAKOTAS WITH A LOW PRESSURE SYSTEM JUST NORTH
OF THE GREAT LAKES REGION. EXPECT THE LOW PRESSURE SYSTEM TO PUSH A
COLD FRONT THROUGH THE REGION LATER TODAY BRINGING ANOTHER SHOT OF
VERY COLD AIR. MEANWHILE AT THE SURFACE, HIGH PRESSURE SHOULD
CONTINUES TO BUILD IN SUPPORTING QUIET WEATHER.
TEMPERATURES AND DEW POINTS WERE SLIGHTLY LOWERED TO MATCH
OBSERVATIONS. MOSTLY SUNNY SKIES ALONG WITH MODEST WARM AIR
ADVECTION AHEAD OF THE APPROACHING COLD FRONT WILL WARM TEMPERATURES
WELL INTO THE TEENS TO POSSIBLY MID 20S OVER FAR S/SW COUNTIES BY
THE AFTERNOON. THE EXTREME COLD WARNING EXPIRED AT 9AM AS
TEMPERATURES HAVE WARMED THROUGH THE MORNING WITH WIND CHILLS NOW
ABOVE WARNING CRITERIA. A COLD WEATHER ADVISORY REMAINS IN EFFECT
FROM 10PM THIS EVENING THROUGH 11AM EST WEDNESDAY MORNING WITH THE
POTENTIAL FOR WIND CHILLS AS LOW AS 20 DEGREES BELOW ZERO.
SHORT TERM (TODAY AND TONIGHT)
ISSUED AT 306 AM EST TUE JAN 27 2026
A VERY COLD NIGHT CONTINUES ACROSS CENTRAL INDIANA, THOUGH
TEMPERATURES HAVE BEGUN TO REBOUND SLIGHTLY AS SOUTHWESTERLY FLOW
STRENGTHENS AHEAD OF THE COLD FRONT EXPECTED LATER TODAY. STILL WIND
CHILLS ARE AS LOW AS -21 ACROSS PORTIONS OF THE AREA, AND WILL KEEP
THE EXTREME COLD WARNING IN PLACE AS IS.
SOME INSOLATION THIS MORNING, ALONG WITH THE ONGOING SOUTHWESTERLY
FLOW, WILL ALLOW TEMPERATURES TO REBOUND INTO THE MID TEENS TO MID
20S ACROSS THE AREA TODAY, THOUGH ACCOMPANIED BY GUSTY WINDS WHICH
WILL KEEP WIND CHILL VALUES MOSTLY IN THE SINGLE DIGITS THROUGH THE
DAY.
INCREASED CLOUD COVER WITH THE BOUNDARY WILL KEEP TEMPERATURES
FROM RECOVERING ANY MORE THAN THIS, THOUGH RAPIDLY CLEARING SKIES
THIS EVENING ALONG WITH THE EXISTING SNOWPACK AND DECREASING WINDS
AS HIGH PRESSURE BUILDS IN BEHIND THE BOUNDARY SHOULD ALLOW
TEMPERATURES TO PLUMMET TONIGHT INTO THE -2 TO -9 RANGE, WITH ANY
WIND PRODUCING WIND CHILL VALUES WELL INTO ADVISORY RANGE, AND
PERHAPS APPROACHING WARNING CRITERIA. FOR THE TIME BEING, HAVE
ISSUED A COLD WEATHER ADVISORY FROM 03Z THIS EVENING TO 16Z
WEDNESDAY, AND THIS MAY BE REFINED DEPENDING UPON GUIDANCE TRENDS
WITH TODAY'S DATA.
LONG TERM (WEDNESDAY THROUGH MONDAY)
ISSUED AT 306 AM EST TUE JAN 27 2026
COLD CONTINUES THROUGH THE LONG TERM WITH NUMEROUS DAYS STILL SEEING
DANGEROUS MINIMUM WIND CHILLS. MODELS ARE IN GOOD AGREEMENT WITH THE
CURRENT TROUGHING PATTERN CONTINUING WITH PERSISTENT NORTHWESTERLY
FLOW ALOFT AND A FEW CLIPPER SYSTEMS PASSING BY.
THE REMAINDER OF THE WORK WEEK WILL SEE HIGHS IN THE TEENS AND LOWS
BELOW ZERO. COMBINED WITH WINDS, NIGHTLY WIND CHILLS OF -10 TO -20
ARE PROBABLE AT LEAST THROUGH THE END OF THE WEEK AND WILL LIKELY
PROMPT ADDITIONAL COLD WEATHER HEADLINES. TEMPS LOOK TO SLIGHTLY
WARM LATE THIS WEEKEND INTO THE START OF NEXT WEEK AS HIGHS COULD
CREEP INTO THE 20S AND MAY FINALLY SEE LOWS ABOVE ZERO AGAIN.
MODELS ARE SHOWING A DECENT UPPER TROUGH POTENTIALLY DROPPING
SOUTHWARD OUT OF CANADA WHICH COULD BRING SCATTERED FLURRIES OR SNOW
SHOWERS AT TIMES LATE WEEK. BEHIND THIS SYSTEM, CAN'T RULE OUT
ADDITIONAL LAKE ENHANCED FLURRIES OVER THE WEEKEND WHEN SURFACE FLOW
IS MORE NORTHERLY. OTHERWISE, PREDOMINATE SURFACE HIGH PRESSURE WILL
KEEP ANY SIGNIFICANT PRECIP AT BAY.
