jhamps10 Posted November 17, 2013 Share Posted November 17, 2013 More than likely it's a PDS as well.. but for some reason when they send out the watch info it doesn't say PDS or not for a few minutes... Just a huge tornado watch indeed, let the fun begin Link to comment Share on other sites More sharing options...

cyclone77 Posted November 17, 2013 Share Posted November 17, 2013 Pretty scary situation over Illinois this morning. I'm probably just gonna shoot a little bit east, and try to keep up with what I can. Not expecting much success chase wise, but you gotta at least take a swing at it.

janetjanet998 Posted November 17, 2013 Share Posted November 17, 2013 REA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 906 AM CST SUN NOV 17 2013 MESOSCALE DISCUSSION 905 AM CST INITIAL STRING OF CONVECTION IS DEVELOPING ACROSS NORTH CENTRAL IL. A MODIFIED 14Z DVN RAOB INDICATES WE ARE ALREADY UNCAPPED BASED ON OUR MID 60S DEW POINTS...WITH SURFACE BASED CAPE 1000-1500 J/KG ALREADY BASED ON THIS. WATER VAPOR AND VISIBLE SATELLITE CHANNELS BOTH INDICATE MULTIPLE NORTH-TO-SOUTH CORRIDORS OF CONVERGENCE WITHIN THE SIGNIFICANT HEIGHT FALLS WHERE CONVECTION WILL LIKELY CONTINUE TO GRADUALLY DEVELOP...WITH AGITATED CUMULUS FROM NORTHERN IL THROUGH CENTRAL MO. INITIAL CELLS HAVE ALREADY SHOWN ROTATION WHICH IS NOT SURPRISING CONSIDERING THE IMPRESSIVE 35-45 KT OF 0-1KM SHEAR AND 60KT+ OF DEEP LAYER SHEAR. WHILE THE LOW-LEVEL SHEAR WILL EASE SOME AS THE LOW-LEVEL WIND MAXIMA MOVES NORTHEAST...IT WILL REMAIN PLENTY HIGH AND WELL ABOVE WHAT RESEARCH HAS SHOWN WHAT IS NEEDED FOR SIGNIFICANT TORNADOES. CONVECTIVE MODE INITIALLY MAY BE THESE STRINGS OF QUICK MOVING NORTHEAST CELLS...BUT IT IS STILL ANTICIPATED THAT INDIVIDUAL DISCRETE CELLS WITHIN THIS...OR JUST ON THEN OWN...WILL BE THE MAIN MODE FROM LATE MORNING THROUGH EARLY AFTERNOON ACROSS MUCH OF THE FORECAST AREA. CONVECTIVE ALLOWING MODELS CONTINUE TO SHOW THIS TREND AND THE LATEST ONES ARE FOR THE MOST PART IN VERY GOOD AGREEMENT. THE MAIN TIME FOR CHICAGOLAND CONTINUES TO LOOK TO BE WITHIN 11AM-3PM. DEVELOPMENT OF STRONG UPDRAFTS WITHIN CONVECTION CAN BE VERY QUICK IN THIS HIGHLY DYNAMIC ENVIRONMENT...WITH SHEAR ON RADAR CORRELATING TO TORNADO DEVELOPMENT IN SHORT TIME. THIS IS EVEN MORE REASON TO MAINTAIN A HIGH AWARENESS. Link to comment Share on other sites More sharing options...
