there might be 8-10 inches in extreme NW Peoria county now...north eastern Knox has 8.5 a couple hours ago....likley a dusting SE portions of the county..I got 1.5 to 2 inches here of wet slop on the NW side of the city the band would work its way through here shortly ..but the duration won't be long

changing to snow as the returns move NNW

I think a new heavy deformation band is developing right over me or just NW a few miles

815 PM HEAVY SNOW FULTON 41.86N 90.16W 11/25/2018 E14.0 INCH WHITESIDE IL TRAINED SPOTTER

for some reason the echoes are weakening in Marshall county and NE....not really sure why...the true dry slot is south it might be sinking air form the heavy mesobands? edit: could be a a semi-dry punch moving in aloft ....destabilizing some areas...causing convection to reform near PIA/BMI

4 hour total 0740 PM HEAVY SNOW ALTONA 41.12N 90.16W 11/25/2018 M8.5 INCH KNOX IL CO-OP OBSERVER SNOWFALL TOTAL SINCE 354 PM.

reminds me of some of the NWS thinking out of Chicago NWS in the 1990's.....when that was a very poor office

all snow here now and there seems to be a very intense mini vortex SSW of me ...could get very interesting here soon

MESOSCALE DISCUSSION 1664 NWS STORM PREDICTION CENTER NORMAN OK 0654 PM CST SUN NOV 25 2018 AREAS AFFECTED...NORTHERN IL AND ADJACENT PORTIONS OF EASTERN IA/SOUTHERN WI CONCERNING...BLIZZARD VALID 260054Z - 260700Z SUMMARY...HEAVY SNOW WILL SPREAD INTO A LARGER PORTION OF NORTHERN IL THIS EVENING. AS STRONGER WINDS MOVE IN FROM THE WEST, BLIZZARD CONDITIONS WILL EXPAND LATER TONIGHT ACROSS THE REGION. DISCUSSION...00Z SURFACE ANALYSIS DEPICTS A 993 MB SURFACE CYCLONE JUST NORTHEAST OF ST. LOUIS. TO THE NORTH AND NORTHWEST OF THE LOW, HEAVY SNOW IS ONGOING FROM NORTHEAST MO INTO NORTHWEST IL, WITH STRONGER WINDS IN THE NORTHWESTERN QUADRANT OF THE CYCLONE PRODUCING BLIZZARD CONDITIONS. DUAL POL PRODUCTS FROM KILX/KLOT AND RECENT SURFACE OBS AND MPING REPORTS INDICATE THAT THE RAIN/SNOW LINE IS MOVING EASTWARD ACROSS NORTHERN IL, AND THIS TREND IS EXPECTED TO CONTINUE AS BACKING SURFACE WINDS RESULT IN INCREASING LOW-LEVEL COLD ADVECTION TO THE NORTH AND NORTHWEST OF THE EAST-NORTHEASTWARD MOVING SURFACE LOW. SNOW SHOULD CONTINUE SPREADING INTO MOST OF THE CHICAGOLAND AREA BETWEEN NOW AND 02Z, THOUGH AREAS IN THE IMMEDIATE VICINITY OF LAKE MICHIGAN MAY SEE A LONGER PERIOD OF MIXED PRECIPITATION AS NORTHEASTERLY WINDS OFF OF THE LAKE MAINTAIN A SLIGHTLY WARMER NEAR-SURFACE LAYER. SUBSTANTIAL CONVECTION HAS BEEN NOTED NEAR THE SURFACE LOW MOVING INTO SOUTHERN IL, WITH A CONVECTIVE CHARACTER TO THE PRECIP (AND SOME THUNDERSNOW REPORTS) ALSO NOTED WITHIN COOLING CLOUD TOPS ACROSS NORTHERN IL. STRONG LOW/MIDLEVEL FRONTOGENESIS WILL CONTINUE TO FAVOR MODERATE-TO-HEAVY SNOW TO THE NORTH OF THE MIDLEVEL LOW, WITH SOME CONVECTIVE ENHANCEMENT POSSIBLE JUST NORTH OF THE MIDLEVEL DRY SLOT, WHERE RELATIVELY STEEP LAPSE RATES (IN EXCESS OF 7 C/KM AS NOTED ON ILX/DVN 00Z SOUNDINGS) WILL BE MAINTAINED. SNOW RATES OF 1-3 INCHES PER HOUR ARE EXPECTED WITHIN THE PRIMARY SNOW BAND, WHICH SHOULD SHIFT GRADUALLY EASTWARD INTO NORTHEAST IL BY LATE TONIGHT. STRONG WINDS (GUSTS IN EXCESS OF 40 KT) ARE RESULTING IN ONGOING BLIZZARD CONDITIONS FROM NORTHEAST MO INTO NORTHWEST IL. THESE STRONGER WINDS WILL EXPAND EASTWARD WITH TIME TONIGHT IN CONJUNCTION WITH THE MOVEMENT OF THE SURFACE LOW, RESULTING IN AN EXPANSION OF BLIZZARD CONDITIONS INTO NORTHEAST IL AND PERHAPS FAR SOUTHEAST WI AFTER 03Z TONIGHT. ..DEAN.. 11/26/2018

all wasted so far although mostly snow now on the NW side 0633 PM HEAVY RAIN PEORIA 40.74N 89.61W 11/25/2018 M1.03 INCH PEORIA IL OFFICIAL NWS OBS RAINFALL IN THE LAST 12 HOURS

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 638 PM CST SUN NOV 25 2018 UPDATE ISSUED AT 630 PM CST SUN NOV 25 2018 GOES IR LOOP SHOWS STRENGTHENING UPPER LOW NORTH OF ST. LOUIS WITH A CLASSIC COMMA HEAD OR DEFORMATION STRUCTURE ACROSS E IOWA AND W ILLINOIS, AND A DRY SLOT TO THE SOUTHEAST. HEAVY SNOW, OCCASIONAL THUNDERSNOW, AND BLIZZARD CONDITIONS WITH N/NW GUSTS OF 35 TO 45 MPH ARE COMMON WITHIN THE DEFORMATION ZONE. STRONG PVA AND UPPER DIVERGENCE DOWNSTREAM OF THE 500MB VORT. MAX WILL LEAD TO A STREAM OF CONVECTIVE ELEMENTS FEEDING NORTHWESTWARD INTO AN INTENSE BAND 700MB FRONTOGENESIS. THE VERY STRONG FORCING AND PRESENCE OF 50+ J/KG OF MUCAPE ARE SUPPORTIVE OF MESOSCALE BANDS OF THUNDERSNOW WITH INTENSE SNOWFALL RATES OF 1-3 INCHES PER HOUR. THE HEAVIEST BAND WILL IMPACT AREAS ALONG AND EAST OF A LINE FROM SOUTHERN CARROLL CO. THROUGH THE QUAD CITIES TO BURLINGTON OVER THE NEXT 2-4 HOURS. TRAVEL IN THE BLIZZARD WARNING COUNTIES AND IN THIS VERY HEAVY BAND OF SNOW IS HIGHLY DISCOURAGED AND MAY BECOME IMPOSSIBLE DUE TO ZERO VISIBILITY.

I wonder what the snowfall rates are in the band between MLI and galesburg

snow mixing in here on the NW side of PIA. very windy

2-3 inch per hr 0610 PM SNOW MENDOTA 41.55N 89.12W 11/25/2018 M2.0 INCH LA SALLE IL NWS EMPLOYEE SNOW FELL IN 40 MINUTES.

the "wavy" portion from PIA to LOT is the model trying to figure out the WAA Versus convective cooling battle.

I still have this concern ...if fact the new HRRR has cut snow totals for the city of peoria and the rain snow line seems to have stalled for now also I believe there is a slug of warm air aloft surging north over Ne IL at this time.. the bright returns on the radar are edging north

9 inches just north of DVN in Scott county IA park view IA

The convective cooling is battling warm air being drawn north from the low...you can see the bright returns( sleet or wet flakes just aloft) trying to battle their way back north see Fulton county SW of PIA and Lasalle county

its cool to watch the rain/snow line surge SE with the convective cooling....but will it stall now for a bit?..its only 15 miles NW of me it seems

looks like extreme NW Peoria county now getting snow per radar

nice start 335 PM SNOW BELVIDERE 42.25N 88.85W 11/25/2018 M5.3 INCH BOONE IL TRAINED SPOTTER

pea sized hail reported near Jefferson city MO I had t-storm , temp low-mid 30's and hail with CG lightning during the Dec 14, 1987 blizzard... between snow dumps

I just don't trust the southern edge of the heavy snowfall model forecast yet (say the SE 25 miles) historically a low moving near SPI to NW IND is way to far north for heavy snow for Peoria county (and points NE) mixing problems (sleet) usually occur or 33 and rain ..until the back edge of the deformation zone moves in with heavy rates but short duration
