Area Forecast Discussion National Weather Service Northern Indiana 1150 PM EDT Fri Jul 3 2020

SYNOPSIS. Issued at 1150 PM EDT Fri Jul 3 2020

Hot and dry conditions continue through the holiday weekend and the start of next week. High temperatures remain in the lower to middle 90s well into next week.

SHORT TERM. (This Evening through Saturday) Issued at 244 PM EDT Fri Jul 3 2020

It's another warm day across the forecast area this afternoon. Upper shortwave ridge center continues to shift southwards in response to a diving shortwave trough currently moving through Lower Michigan and central Lake Michigan. Models continue to flip- flop as to the potential for isolated storms to develop later this afternoon/evening as the shortwave drops across the forecast area. Despite these differences the area at which these chances may or may not actualize has remained consistently focused across SE MI/NE IN/NW OH. Forecast soundings continue to lean towards virga being the more likely case should these storms materialize. As such will continue a dry forecast.

After sunset any ongoing virga showers will quickly dissipate with the loss of daytime heating. The upper shortwave trough will continue to slowly drop into the forecast area overnight. Overnight lows should hold in the 60s.

On Saturday, the shortwave trough becomes stalled over central IN as the shortwave ridge interacts with shortwaves over western IL and MO. With the forecast area mainly on the backside of the shortwave trough will help to keep the area dry once again as temperatures reach into the lower 90s. A few models show convection developing mainly across the southern half of the forecast area, but again soundings will be lacking sufficient moisture. Will continue with the dry forecast for this issuance.

LONG TERM. (Saturday Night through Friday) Issued at 244 PM EDT Fri Jul 3 2020

Sunday will see the upper pattern transition to a dominate ridge over the southwestern US while broad troughing develops over the southeastern US. Weak ridging over the western Great Lakes should help to maintain the hot and dry conditions with a slight uptick in humidity. By Monday the upper flow becomes more zonal as low level winds become more southerly. This will help with moisture transport back into the forecast area.

Tuesday through Thursday could see the return of precip chances as within zonal to northwest flow aloft. Each day could see some chance for precip, but that will be highly dependent on timing of the embedded shortwaves. Low level moisture return from the Gulf of Mexico will also help in increasing afternoon heat index values into the upper 90s. With multiple days where heat index values are forecast to reach or exceed 95 degrees a heat advisory may be needed for the middle to second half of the week.

AVIATION. (For the 06Z TAFS through 06Z Saturday Night) Issued at 1150 PM EDT Fri Jul 3 2020

Surface ridge sprawled over the Upper Great Lakes to provide VFR conditions through the forecast period, and beyond, at least into early next week.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
