Area Forecast Discussion National Weather Service Northern Indiana 326 PM EDT Thu Jul 29 2021
SYNOPSIS. Issued at 321 PM EDT Thu Jul 29 2021
A shower or storm is possible late this afternoon, but most storms stay sub-severe. Drier air filters in tonight allowing Friday and Saturday to stay dry. Cool weather with highs struggling to reach 80 degrees remains through the work week.
SHORT TERM. (This Evening through Friday) Issued at 321 PM EDT Thu Jul 29 2021
The recovery behind the morning convection has allowed for some showers and storms along the southern 2 tiers of counties in our forecast area ahead of a low to mid level shortwave continuing to slide southeast. This particular shortwave is shearing out and on the dissipating trend and the marginal shear would tend to lean towards non-severe storms, but the 3000 J/kg of CAPE may allow a stronger storm to pop through. The best chance for a stronger storm would be south of US-24.
Tonight, drier air and cooler temperatures associated with the upper low in northeast Canada are able to move in. This will allow for cooler overnight temperatures in the upper 50s to low 60s as opposed to the previous night's lows, which were around 70 degrees.
High pressure passes overhead Friday keeping the area dry and with some passing clouds. With the cooler air aloft, this will keep highs in the low to mid 70s and dew points only in the 50s.
LONG TERM. (Friday Night through Thursday) Issued at 321 PM EDT Thu Jul 29 2021
Dry weather continues on Saturday, although slightly warmer, with high pressure overhead and just some clouds around. Highs rise a few degrees higher than today, into the mid to upper 70s. Dew points are a little higher, though still comfortable at less than 60 degrees.
Sunday is our next chance for showers as a shortwave pinwheeling around the upper low in southeast Canada approaches for the morning into the afternoon time frame. Models still vary on the placement of the wave and how quickly it is able to pinwheel around the upper low. In addition, it is still on the drier side with dew points only able to rise into the low to mid 60s likely capping instability below 1000 to 1500 J/kg so will settle on 20 to 30 PoPs at best. The earlier the wave arrives, the worse our chances are for showers, and especially storms.
Outside of that, will continue with the dry forecast as northwest flow continues to keep our temperatures in the 70s to near 80 degrees. This is as cyclonic wave breaks occur over the North Atlantic essentially blocking the west to east flow. There is some indication that afternoon pop showers might be possible during the work week, but with how cool and dry the forecast is, will keep those chances out for now.
AVIATION. (For the 18Z TAFS through 18Z Friday Afternoon) Issued at 150 PM EDT Thu Jul 29 2021
CAM's continue to struggle with convective development for this aftn. Latest radar trends reflect spotty showers trying to form se and sw of the KFWA terminal where a more rich airmass is in place. Convection from this morning effectively pushed the boundary well south of the terminal sites though will carry vcnty at KFWA for a few hours this aftn/evening. Otherwise satellite imagery showing a MVFR/VFR deck over northern IN has impacted both terminal sites which will likely prevent temperatures from rising much further in the immediate area. Winds will remain predominately wnw for both sites through the fcst period.
A QLCS system was moving across northern Indiana at this time. The storms had moved through SBN earlier and were moving across the FWA terminal. Gusty winds are likely with the storm passage along with some MVFR ceilings. The front was farther behind the line and should across the area around midday accompanied by a wind shift to the northwest. Clearing skies will follow later with VFR conditions.
