Area Forecast Discussion National Weather Service Northern Indiana 709 PM EDT Mon Jun 14 2021
SYNOPSIS. Issued at 138 PM EDT Mon Jun 14 2021
Showers and thunderstorms toward northwest Ohio will diminish after sunset. Cooler and much less humid conditions will settle in through mid week.
SHORT TERM. (Late This Afternoon through Tuesday) Issued at 230 PM EDT Mon Jun 14 2021
Two compact shortwaves will translate south through the area on the backside of an amplifying eastern conus upper trough, one late this aftn/eve, and another late tomorrow aftn. Steep lapse rates and weak diurnal instability under the associated cold pockets aloft (5H temps to -17C) may be enough to generate a few showers in the vicinity of an area of subtle low level convergence across far ne IN/sc MI/nw OH each aftn/eve. Steep lapse rates, high sfc T-Td depressions, and modest background northerly flow may support some higher end wind gusts if any stronger showers develop, best chances late this aftn-early eve. Comfortable, dry canadian airmass in deep northerly flow will provide mainly clear skies and dry conditions otherwise into tonight and Tuesday.
LONG TERM. (Tuesday Night through Monday) Issued at 230 PM EDT Mon Jun 14 2021
Canadian high pressure will build in for the middle of the week with light winds, mainly clear skies, large diurnal temp ranges and low humidity levels. Flow pattern does flatten out a bit by late in the week with models in good agreement on a more progressive northern stream trough breaking down a High Plains ridge. This will drive a warmer/more unstable airmass into the region with chances for convection along a cold front later Thursday night-Friday. Good mid level flow/shear on the northeast fringe of an EML plume continues to hint at a severe wind threat if/where convection organizes. Ensemble guidance does continue to differ a bit on timing and moisture return which will be key to thunder/severe chances. Held with mid chance PoPs as a result, and will continue to monitor trends over the coming days.
Front will likely settle south of the area in time for the weekend under broad troughing aloft with mainly dry/seasonable conditions anticipated. Chances for convection then return early next week as the next northern stream trough/front tracks through.
AVIATION. (For the 00Z TAFS through 00Z Tuesday Evening) Issued at 704 PM EDT Mon Jun 14 2021
Clouds may be on the increase at KFWA over the next few hours as an area of showers and storms drops in over northwest Ohio. The line is becoming outflow dominant, thus leading me to believe a dry TAF is ok. This will result in a northerly wind shift briefly.
Otherwise, at both KSBN and KFWA, breezy winds will diminish within a couple hours as will diurnal clouds. Look for winds to increase again late tomorrow with a few clouds sprouting up associated with a weak upper-level system sweeping in. There is a non-zero chance for rain, but coverage is expected to be sparse.
