SNOW AND ICE THURSDAY Northern Indiana (from Kokomo northward) sits firmly in the cold sector, with snow expected statewide across this zone. Accumulations will depend on banding and surface temperatures, but travel impacts are likely, especially near Fort Wayne and South Bend. Central Indiana, including Indianapolis, lies in the transition zone where freezing rain and sleet dominate. This corridor — stretching from Kokomo down to Bloomington — is primed for icing conditions, with elevated surfaces and untreated roads at risk. Expect slick travel and potential power disruptions if ice accretion intensifies. Southern Indiana, from Bloomington southward, remains in the warm sector with rain expected across the region. While surface temps stay above freezing, gusty winds and moderate rainfall may lead to ponding in low-lying areas. #snow #ice #rain #wx #inwx

Winter Transition Event (Jan 10–11, 2026) A dynamic mid-latitude cyclone will traverse the Midwest and Ohio Valley this weekend, delivering a classic rain-to-snow transition across Indiana, Illinois, and surrounding states. The NAM 3km model highlights a well-defined thermal gradient, with the 540 thickness line acting as a sharp divider between rain in the south and accumulating snow in the north. Atmospheric Evolution & Precipitation Type Breakdown Saturday @ 12 PM EST: Rain dominates southern Indiana, Kentucky, and southern Illinois. Snow begins in northern Indiana (Gary, Fort Wayne, Kokomo) and parts of central Illinois. The 540 line bisects the state, signaling the rain/snow boundary. Saturday @ 11 PM EST: Snow expands southward, reaching Indianapolis, Bloomington, and Urbana. Rain retreats to far southwestern zones near Evansville. Isobars tighten, suggesting enhanced surface convergence and steady precipitation rates. Sunday @ 5 AM EST: Snow dominates central Indiana and southern Ohio, with lingering bands over Fort Wayne, Muncie, and Lexington. Ice potential appears minimal, but cold air advection supports sustained snow rates. Surface pressure field stabilizes, indicating system exit and post-frontal cooling. Impacts & Forecast Confidence Snow Accumulation: Moderate totals possible north of I-70, especially from Kokomo to Fort Wayne and Urbana. Rainfall: Light to moderate in southern zones, with minimal flooding risk. Travel Hazards: Slushy roads and reduced visibility Saturday night into Sunday morning. Confidence: High in precipitation type evolution; moderate in exact snow totals due to mesoscale banding uncertainty. #snow #cold #weathertok #snowday #indiana

Watching a system that should be arriving next week. A low-end but credible severe weather signal is emerging across portions of the Mid-South and Lower Ohio Valley, as ensemble guidance begins to converge on a more organized system late next week. #indiana #weatherreport #inwx #weatherforecast #storms

Valid Through Saturday Evening A cold, quiet pattern holds across the state today, but model guidance is signaling a shift toward active winter weather by Saturday evening. The HRRR simulated radar for Saturday, January 3 @ 7 PM EST shows a developing shield of snow, ice, and sleet advancing into central and northern Indiana, driven by mid-level lift and a tightening thermal gradient. 🧭 Current Conditions (Central Indiana) Temperature: 34°F Wind: Northwest at 6–10 mph Sky Cover: Partly cloudy Pressure: 1024 mb and rising Dew Point: 21°F Visibility: 10 miles UV Index: 2 (Low) Meteorological Setup A surface high pressure ridge remains in control today, keeping skies quiet and dry. By Saturday evening, a low-pressure system approaches from the southwest, introducing warm advection aloft and moisture return. The HRRR model shows a classic wintry mix setup, with snow dominating north of I-70, and ice/sleet signatures appearing across central Indiana. Isotherms (534/546 dam) suggest a sharp thermal boundary, with freezing rain possible where warm air overrides subfreezing surface temps. #indy #snow #ice #northernindiana #indiana

A Wind Advisory remains in effect until 5 PM EST for much of central, south‑central, southeast, and southwest Indiana, as a strong pressure gradient behind the departing storm system continues to drive gusty west winds across the region. ⚠️ Impacts Unsecured objects may be blown around. Tree limbs could come down. Sustained west winds: 15–25 mph Peak gusts: Up to 45 mph, occasionally higher in exposed areas These winds are being driven by a tight pressure gradient behind the cold front that swept through earlier. #wind #illinois #indy #INwx #indiana

SNOW IS ON THE WAY!!! A low-pressure system tracks eastward across the Midwest, tightening isobars and deepening the surface low. The system drags a cold front and upper-level trough, producing widespread snowfall across northern Illinois, Indiana, Michigan, and Ohio. Precipitation type transitions from rain to snow, with ice and sleet briefly mixing in southern zones. 🕕 Monday Morning (6 AM EST – Dec 29) Snow begins across northern Illinois, Indiana, and Ohio, with MSLP near 992 mb indicating a strengthening low. Isobars tighten, suggesting gusty winds and falling pressure. Thickness contours (522–528) confirm cold air entrenched aloft, supporting snow development. 🕙 Monday Mid-Morning (10 AM EST) Snow intensifies across Chicago, Indianapolis, Toledo, and Lansing. The 528 line dips south, reinforcing cold air advection. Precipitation remains mostly snow, with light to moderate rates expanding eastward. 🕒 Tuesday Afternoon (3 PM EST – Dec 30) Snow continues across Wisconsin, northern Illinois, Indiana, and Michigan. Isobars show a broad high-pressure ridge building behind the system, helping lock in cold air. Snow bands remain organized, with moderate intensity over central Indiana and southern Michigan. 🕖 Tuesday Evening (7 PM EST) Widespread snow persists across northern Indiana, southern Michigan, and parts of Ohio. The system begins to exit eastward, but lingering wraparound snow continues. Isobars (1010–1022 mb) suggest pressure recovery, but winds may remain breezy. 🕙 Tuesday Night (10 PM EST) Snow tapers off in western zones but continues in eastern Indiana and Ohio. Rain lingers near Chicago and Milwaukee, indicating a warm nose aloft or residual surface warmth. Most of Indiana is locked into steady snow, with cold surface temps and light accumulation continuing overnight. #INwx #WeatherAlert #WeatherUpdate #indiana #snow

Storm update for Sunday 28th Wind risk – primary, broad severe threat Product: CSU-MLP Day 1 Wind Probability Max probability: 0.239 (about a 24% chance in the “hot spot”) What it shows: A broad swath of wind risk stretches from the central Plains into the Midwest, with the core of concern over Illinois, Indiana, and eastern Missouri. The highest probabilities (yellows and browns) sit right over that IL–IN–MO corridor, indicating that damaging winds are the leading severe hazard. The scale tops out at 0.45, but the max in this run is 0.239, which is still quite notable for a probabilistic, national-scale product. What it means in plain language: This strongly favors a scenario with organized thunderstorms, likely forming into lines or bowing segments that can produce: Widespread 50–60+ mph wind gusts Power outages Tree damage Difficult travel, especially for high‑profile vehicles Because wind probabilities are higher and more expansive than hail or tornado probabilities, this is a “damaging wind–driven” event, not just a few isolated storms. 2. Hail risk – secondary but credible severe hazard Product: CSU-MLP Day 1 Hail Probability Max probability: 0.183 (about an 18% chance in the core area) What it shows: The hail risk is focused in a similar region—centered over Illinois and Indiana, with some extension into neighboring states. The most intense shading (yellows) marks the zone of greatest hail potential, surrounded by browns indicating lower but still non‑zero risk. The scale runs up to 1.00, but this particular forecast tops out at 0.183, which is moderate but meaningful. What it means in plain language: The environment supports strong updrafts—storms that can lift hailstones high enough and long enough to grow. This setup favors: Severe hail (quarter size or larger) in stronger cells Potential for larger hail if any discrete supercells form ahead of the main line Hail is not as dominant as the wind threat, but it’s absolutely in play and should be highlighted, especially in messaging about isolated stronger storms. 3. Tornado risk – lower in probability, but not negligible Product: CSU-MLP Day 1 Tornado Probability Max probability: 0.085 (about an 8.5% chance in the hot spot) What it shows: The tornado risk is more focused and smaller in area than wind or hail, centered again over Illinois and Indiana and nearby states. The shading is mostly in the green–brown range, with a black dot marking the location of the maximum probability. The scale goes from 0.00 up to 0.55, but the max for this event is 0.085, meaning: This is not a classic, high‑end tornado outbreak signal But it is absolutely enough to justify concern for isolated tornadoes, especially in the same corridor highlighted for wind/hail. What it means in plain language: Ingredients are present for rotating storms, likely embedded within a larger line or broken line of storms. The most likely tornado scenario: A few isolated tornadoes, possibly brief Spin‑ups along a squall line or QLCS, especially near kinks or bows in the line This is not a day to hype as a “tornado outbreak,” but it is a day where any warning must be taken seriously because the background environment supports tornadic storms. #storm #windy #cold #tornado #thunder
