Area Forecast Discussion National Weather Service Northern Indiana 731 PM EDT Sat Jul 4 2020

SYNOPSIS. Issued at 729 PM EDT Sat Jul 4 2020

The heat continues through next week, with heat indices ranging from the mid to upper 90s. It will be mostly dry, but there are intermittent chances for afternoon showers and thunderstorms Tuesday into Friday.

SHORT TERM. (This Evening through Sunday) Issued at 234 PM EDT Sat Jul 4 2020

The stalled upper vort lobe from SE to NW has coupled with available instability to initiate isolated showers and thunderstorms this afternoon. Slow storm motions and PWAT values around 1.5" will allow storms produce locally heavy rainfall. A brief strong wind gust near 40 mph can't be ruled out given precipitation loading of the downdrafts. Convective activity should wain around sunset. This will lead to a dry overnight period as temperatures drop into the mid- 60s.

Similar setup to start off with Sunday morning with the stalled vort lobe still over the area. As the morning progresses, a trough swinging southwards across the Lower Great Lakes will help send the vort lobe south of the area around midday. Models depict a surface theta-e gradient across the SW corner of the CWA during the same timeframe before washing out during the afternoon/evening hours. Some models develop isolated convection once again using this theta-e gradient as a focus, but vary on whether this gradient is sufficiently within our CWA to warrant POPs. As things stand right now, isolated storms can't be entirely removed from the table, but will keep POPs below mentionable with this issuance. High temperatures will also be slightly higher in the lower to mid-90s by the afternoon. Since we are expected to deeply mix, will see a lowering trend of the dewpoints throughout the day which will help keep the heat index near the air temperature.

LONG TERM. (Sunday Night through Saturday) Issued at 234 PM EDT Sat Jul 4 2020

Hot and mostly dry conditions persist into Monday as the upper flow becomes more zonal. Despite slightly lower heights aloft, afternoon high temperatures will still be capable of reaching into the low to mid-90s.

Tuesday through Friday continues to hold the best shot at seeing precip chances return as well as hotter high temperatures. These precip chances will be associated with a series of troughs which propagate through the zonal flow. At this time, the timing of these troughs correlates with peak heating, and POPs have been limited mainly to these windows. PWATs are expected to remain above average for this time of year so storms that form will be capable of locally heavy rainfall. Expect timing and location to be refined with future issuances.

Looking at heat concerns, each day from Tuesday into Thursday is expected to be gradually warmer. This results with high temperatures in the lower to mid-90s on Tuesday with mid to upper 90s possible by Thursday. While each day is below criteria for heat headlines individually, the consecutive days of air/heat index values would be enough to warrant a heat headline. Now, what could prevent these warm temperatures from actualizing could be the precip mentioned above. Should the storms occur through peak heating, then temperatures may hold just below the needed threshold to warrant a headline. Will hold off on raising any headlines this issuance given these potential factors and continue to relay concerns via HWO.

AVIATION. (For the 00Z TAFS through 00Z Sunday Evening) Issued at 729 PM EDT Sat Jul 4 2020

Afternoon storms are again possible on Sunday, but with confidence not high on formation will include a VCSH at SBN only. VFR conditions expected through the period, otherwise, with light winds out of the southeast on Sunday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
