A little late posting this but there's a Severe Thunderstorm Warning south of Quincy--and if this storm holds straight east the remnants might affect SPI in a few hours:

Just after the range on this thread, but today looks like it could have some potential in southeast IL/south half of IN.  Thinking about running down there in a bit.  

 

Moisture is there, nice hodos despite rather weak low-levels.  If we could get the low-levels to ramp up a bit more this would be a very potent setup.  Even with that, the instability looks pretty nice, with forecast cape up over 2500j/kg in the warm sector.  I could see a cell or two doing very well if it becomes dominant for awhile.  Think I may head down towards Effingham or Terra Houte and see what happens.  Be nice to be out of this 40s and grunge weather at least lol.

MESOSCALE DISCUSSION 0527

   NWS STORM PREDICTION CENTER NORMAN OK

   0821 PM CDT SUN MAY 01 2016

   AREAS AFFECTED...PORTIONS OF CENTRAL/SOUTHERN INDIANA...FAR

   SOUTHEASTERN ILLINOIS...SOUTHWESTERN OHIO

   CONCERNING...SEVERE THUNDERSTORM WATCH 136...

   VALID 020121Z - 020315Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 136

   CONTINUES.

   SUMMARY...THE THREAT FOR DAMAGING WINDS AND LARGE HAIL WILL PERSIST

   FOR AT LEAST A COUPLE MORE HOURS. THEREAFTER...CELLS SHOULD

   GRADUALLY WEAKEN...BUT CONVECTIVE TRENDS WILL BE MONITORED FOR

   POTENTIAL DOWNSTREAM WATCH ISSUANCE.

   DISCUSSION...SEVERAL ROBUST SUPERCELLS ARE PUSHING EAST ACROSS

   CENTRAL INDIANA AND FAR SOUTHEASTERN ILLINOIS THIS EVENING. RECENT

   KIND VWP DATA DEPICT A KINEMATIC ENVIRONMENT SUPPORTIVE OF CYCLONIC

   ROTATION...AS SOUTHERLY LOW-LEVEL WINDS VEER TO VIGOROUS WESTERLY

   FLOW AT/ABOVE 6 KM AGL. FURTHERMORE...SEVERAL ZDR ARC SIGNATURES

   HAVE BEEN OBSERVED...DEPICTING RAIN DROP SIZE SORTING WITHIN A

   VEERING STORM-RELATIVE WIND PROFILE. THESE CELLS WILL CONTINUE TO BE

   CAPABLE OF LARGE HAIL...STRONG WINDS...AND PERIODIC LOW-LEVEL

   MESOCYCLONES.

   FARTHER EAST...A NORTHWARD-PROGRESSING OUTFLOW BOUNDARY IS

   INITIATING NEW CONVECTION ACROSS PORTIONS OF OHIO. MOST

   LIKELY...THIS ACTIVITY SHOULD ALTER THE DOWNSTREAM ENVIRONMENT

   ENOUGH SUCH THAT THE INDIANA CELLS MOVING EAST WILL WEAKEN OVER

   TIME. ADDITIONALLY...RELATIVELY LOW SFC DEW POINTS WILL ALLOW TEMPS

   TO FALL FAIRLY QUICKLY THIS EVENING...STABILIZING THE BOUNDARY

   LAYER. AS SUCH...DOWNSTREAM WATCH ISSUANCE IS NOT ANTICIPATED...BUT

   CONVECTIVE TRENDS WILL BE MONITORED FOR SUSTAINED UPDRAFT

   ORGANIZATION WITH EASTWARD EXTENT.

   ..PICCA.. 05/02/2016
