.FORECAST UPDATE...

Issued at 1027 PM EDT Wed Mar 18 2026



Clouds are starting to move back in as moisture increases ahead of 

the next system. Only minor adjustments were needed for the forecast 

to better match current observations, otherwise it is in good shape. 

Still watching for a chance of rain clipping the NE counties 

early in the morning. Otherwise expect lighter winds overnight and

increasing cloud coverage with lows in the mid to upper 30s.

.SHORT TERM (This evening through Thursday)...

Issued at 321 PM EDT Wed Mar 18 2026



A fairly quiet evening is in the offing for central Indiana as high 

pressure nudges into the area. The low clouds are steadily 

eroding/pushing eastward, which will allow for a relatively clear 

evening across the area, before additional high cloud and then mid 

cloud moves in late with a weak upper level disturbance.



Mid and upper levels will moisten up associated with this, hence the 

increased cloud cover late tonight into early tomorrow, but the low 

levels remain substantially dry. Will carry some low PoPs in the 

northeast late tonight into Thursday morning, but amounts, if any 

measurable, will be quite minimal.



Skies should clear relatively quickly by the afternoon, which along 

with increased low level thicknesses will allow temperatures to 

recover from morning lows in the 30s to around 40 to afternoon highs 

in the upper 50s to mid to upper 60s across the area.

.LONG TERM (Thursday night through Wednesday)...

Issued at 321 PM EDT Wed Mar 18 2026



Though the pattern will largely remain characterized by a 

substantial western/southwestern CONUS ridge and northwest or at 

least WNW flow aloft, substantially warmer conditions are expected, 

particularly during the first half of the long term period or 

through the coming weekend, as the ridge flattens a bit and nudges 

eastward, and significant low level warm advection occurs.



Temperatures should near or exceed the 70 degree mark each day 

Friday through Saturday, with 80 degree readings not entirely out of 

the question south late in the weekend.



This will be accompanied by dry conditions for the most part, save 

for a low chance for showers Sunday into Sunday night as a front 

sinks through the area and brings temps back down to nearer normal 

at least briefly early next week. High pressure over the Gulf will 

limit moisture availability, thus the lower PoPs.



The cooldown should be relatively brief, as the western ridge 

restrengthens and nudges even a bit further eastward toward the end 

of the period next week.

.AVIATION (06Z TAF Issuance)...

Issued at 135 AM EDT Thu Mar 19 2026



Impacts: None



Discussion:



VFR conditions and light winds to prevail over central Indiana 

terminals through Thursday evening.  Weak yet elongated surface high 

pressure aligned from the Gulf coast to New England...will allow 

light and generally variable surface winds through 14Z Thursday... 

followed by south-southeasterly flow around 5KT through the 

afternoon.  A ceiling of high cloud will fall towards 12,000 feet 

during 11Z-15Z...before scattering out later this morning.



Next, much weaker weather system, crossing the Upper Midwest by the 

end of the TAF period will nudge wind speed up slightly late tonight 

at KIND to around 9KT by 12Z Friday.
