Sunday/Mid Afternoon

WEATHER CODE: GREEN ***No hazardous weather expected today or tonight***

Focus will be on potential for severe weather tomorrow...

Temperatures region wide are in the middle 80's as of 2:30. Still may see temperatures rise a couple of more degrees, which will top temperatures out into the upper 80's.

Tomorrow we will pay for the warmer weather with showers and thunderstorms that will develop along a cold front by late afternoon and evening. Some of these storms will become severe with the main threat being be large hail and damaging winds. (Latest maps and discussion below) However, isolated tornadoes cannot be ruled out. Right now the best threat for severe weather appears to be I65 and on to the west and southwest. Our southern Indiana counties have the best shot at seeing some nasty storms tomorrow night. Would not be suprised to see parts of Western Indiana and Illinois upgraded to a moderate risk tomorrow. The latest models/soundings suggest the potential is increasing for very large hail (quarter size or larger) in that area.

SEVERE WEATHER OUTLOOK-Monday



SEVERE WEATHER PROBABILITY



SPC SAYS: THE PARENT UPPER SYSTEM WILL BEGIN TO SHIFT NORTHEASTWARD AWAY FROM THE REGION MONDAY AFTERNOON...BUT MODERATELY STRONG WESTERLY FLOW ALOFT AND A BROAD MOIST/POTENTIALLY UNSTABLE WARM SECTOR WILL SUPPORT A SEVERE RISK ESPECIALLY ACROSS PORTIONS OF IL/MO/INDIANA MONDAY AFTERNOON/EVENING. A MIXED MODE OF SOME INITIAL SUPERCELLS WILL BE POSSIBLE...BUT OTHERWISE AN EVOLUTION TO MULTICELLULAR CLUSTERS/SMALL BOWING COMPLEXES SEEMS LIKELY. SEVERE HAIL AND DAMAGING WINDS WILL LIKELY THE PRIMARY HAZARDS. EVEN WITH A TENDENCY FOR VEERING/WEAKENING LOW LEVEL FLOW...A FEW TORNADOES MAY BE POSSIBLE MAINLY ACROSS PORTIONS OF IL/INDIANA...AND POTENTIALLY INTO LOWER MI IN VICINITY OF NORTHWARD RETREATING WARM FRONT AND APPROACHING SURFACE LOW. IN ADDITION TO LOWER MI...THE SEVERE THREAT MAY REACH PORTIONS OF WESTERN/NORTHERN KY AND WESTERN OH MONDAY NIGHT.
