Update 4/2416 @7:00pm

It's warming up out there! Temperatures in the mid 80's for this week. There's an off-and-on 30-40% chance of thunderstorms each day this week. Not much else to talk about until Thursday, June 2. The GFS has a retrograding low pressure showing up that day. That should be interesting watch.

Cold air funnel clouds are possible today.

...COLD AIR FUNNELS POSSIBLE TODAY...

GENERALLY FUNNEL CLOUDS DEVELOP AND OCCUR IN CONJUNCTION WITH
CONDITIONS THAT PRODUCE SEVERE THUNDERSTORMS.

AN ENTIRELY DIFFERENT CONDITION PREVAILS ACROSS CENTRAL INDIANA
TODAY. THERE IS LITTLE POTENTIAL FOR SEVERE THUNDERSTORMS.

RESEARCH STUDIES OF FUNNEL CLOUD OCCURRENCES INDICATE THAT A
DIFFERENT TYPE OF FUNNEL CLOUD FORMS WHEN WEATHER CONDITIONS ARE
SIMILAR TO THOSE OF TODAY. THESE ARE CALLED COLD AIR FUNNELS...AND
ARE NOT AS VIOLENT AS THOSE ASSOCIATED WITH WARM AND HUMID
CONDITIONS.

COLD AIR FUNNELS ARE ASSOCIATED WITH THUNDERSTORMS THAT FORM IN
DEEP... COLD-CORE...LARGE-SCALE LOW PRESSURE SYSTEMS. THESE FUNNEL
CLOUDS ARE SMOOTH AND NARROW. THEIR PARENT THUNDERSTORMS ARE NOT
PARTICULARLY TALL OR INTENSE. THESE FUNNEL CLOUDS NORMALLY PROTRUDE
A FEW HUNDRED FEET DOWNWARD FROM THE PARENT CLOUDS...ROTATE OR SPIN
LIKE A TOP...AND LAST A FEW MINUTES BEFORE DISSIPATING.

IN RARE CASES WHEN THEIR CIRCULATIONS DO REACH THE GROUND...COLD AIR
FUNNELS CAUSE ONLY MINOR DAMAGE. MORE REPORTS OF SMALL FUNNEL CLOUDS
ARE POSSIBLE OVER CENTRAL INDIANA TODAY. WARNINGS WILL BE ISSUED IF
ANY OF THEM TOUCH THE GROUND.

Wednesday 5/4/26

There's a low pressure system centered over Ohio. It is spinning down bands of hit-or-miss showers and thunderstorms. That's why today has been sunny followed by very dark clouds and then sunny again followed by more dark clouds. 


There low temperature will be 41 degrees tonight. We reach 80 degrees by Saturday followed by another slight cool down on May 13.
