  10. REA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE, IL 1047 AM CST THU FEB 4 2021 UPDATE 1047 AM CST THE GOING FORECAST IS IN GOOD SHAPE, WITH NO MAJOR CHANGES PLANNED. THE INGREDIENTS ARE COMING TOGETHER TO SUPPORT AN PERIOD OF MODERATE TO HEAVY WET SNOW ACROSS THE AREA THIS AFTERNOON. WE SEE THIS WITH THE COMBINATION OF UPPER LEVEL JET SUPPORT ASSOCIATED WITH AN APPROACHING MID-LEVEL IMPULSE, AND STRONG LOWER-LEVEL ISENTROPIC UPGLIDE AND MOISTURE TRANSPORT INTO THE AREA. THIS YIELDS HIGH CONFIDENCE IN THERE BEING SOME RESPECTABLE PRECIPITATION AMOUNTS ACROSS THE AREA THIS AFTERNOON. WE ARE ALREADY SEEING THE BEGINNINGS OF THIS EVENT, WITH PRECIPITATION NOW DEVELOPING INTO NORTH CENTRAL IL. THE PRECIPITATION TYPE IS BEGINNING AS A SHORT (<1 HOUR) PERIOD OF RAIN AND SLEET. THIS IS DUE TO A WARM LAYER ALOFT THAT WAS SAMPLED OFF A RECENT AMDAR SOUNDING OUT OF KRFD TO BE AROUND 3.5C AT 850MB. WHILE A WARM LAYER OF THIS MAGNITUDE WOULD NORMALLY BE CAUSE FOR CONCERN, THIS WARM LAYER IS ALSO FAIRLY DRY, WHICH WILL YIELD HIGH EVAPORATIVE COOLING AS THE PRECIPITATION FALLS THROUGH THE LAYER. FOR THIS REASON, WE EXPECT SNOW TO BECOME THE DOMINANT PRECIPITATION TYPE WITHIN AN HOUR OF PRECIPITATION START TIME. THIS HAS BEEN THE TREND OVER THE KDVN AREA, WHERE THEY QUICKLY TRANSITIONED OVER TO SNOW. OUR HEAVIEST PERIOD OF SNOW STILL LOOKS TO BE THIS AFTERNOON ROUGHLY FROM ABOUT 1 PM THROUGH 7 PM THIS EVENING. DURING THIS PERIOD THE POTENTIAL FOR HEAVY WET SNOW COULD YIELD SNOW RATES UP TO AN INCH PER HOUR AT TIMES. THE SNOW SHOULD THEN BEGIN TO WIND DOWN BY MID TO LATE THIS EVENING AS A STRONG COLD FRONT PUSHES EASTWARD ACROSS THE AREA. IN THE WAKE OF THIS FRONT, EXPECT OUR GUSTY SOUTHERLY WINDS TO QUICKLY TURN WESTERLY AND INCREASE IN MAGNITUDE. IT APPEARS WINDS WILL GUST UP TO 40 TO 45 MPH FOR A PERIOD THIS EVENING BEFORE EASING SOME OVERNIGHT. THIS CAUSES CONCERN FOR SOME SIGNIFICANT BLOWING AND DRIFTING SNOW TONIGHT, IN SPITE OF THE SNOW FALLING TODAY BEING A WETTER TYPE. THE HIGHEST POTENTIAL FOR SIGNIFICANT BLOWING AND DRIFTING SNOW WILL BE IN MORE WIDE OPEN AREAS OUTSIDE MORE URBAN AREAS. COLD THEN BECOMES THE MAIN STORY FOR FRIDAY, WITH HIGHS EXPECTED TO REMAIN IN THE TEENS. KJB
  11. NAM weaker more south still nickels and dimes NE IL with 1-2 central IL 4
  12. the central park figure may be correct at this point but the segments don't make sense 15.3 at 1pm 18.3 at 7pm but .7 inches of precip in between?? https://w1.weather.gov/data/obhistory/KNYC.html
