Area Forecast Discussion National Weather Service Indianapolis IN 124 PM EDT Tue Jul 7 2020 .UPDATE... The SYNOPSIS...NEAR TERM and SHORT TERM Sections have been updated below. && .SYNOPSIS... Issued at 124 PM EDT Tue Jul 7 2020 A very warm and humid air mass will remain over Central Indiana through Friday. This will result in daily chances for afternoon showers and thunderstorms along with above normal temperatures. A brief break in the hot weather is expected this weekend before reverting back to the hot and humid pattern early next week. && .NEAR TERM /Tonight/... Issued at 124 PM EDT Tue Jul 7 2020 Surface analysis early this afternoon shows a large but poorly organized area of high pressure over Illinois and Indiana. A warm and humid air mass remained in place across the forecast area with dew point temps in the lower 70s. GOES16 shows CU popping across Central Indiana and radar is beginning to light up with isolated showers and storms. Aloft water vapor shows ridging in place across the southwestern states...steering the upper flow and any associated forcing across the upper midwest and Great Lakes. Little change is expected tonight in the overall pattern. Ongoing diurnal showers and storms are expected to diminish as heating is lost later today. Will still need to carry a few hours of evening showers and storms possible through 00Z...but will drop pops rapidly after that as all forcing mechanisms are lost...trending toward partly cloudy skies. Will keep overnight lows close to persistence. && .SHORT TERM /Wednesday through Friday/... Issued at 124 PM EDT Tue Jul 7 2020 Wednesday and Wednesday night look quite similar to the past few days as the warm and humid air mass will remain in place across Central Indiana. Models indicate a rather stagnant flow aloft. Thus will continue the trend of afternoon and evening showers and storms. This diurnal storm development is supported by forecast soundings showing over 2400 J/KG of CAPE...pwats over 1.7 inches and attainable convective temps. Again after heating is lost in the evening...dry weather will return. On Thursday the upper flow begins to change a bit as a short wave is suggested to begin an approach on Central Indiana from IA. Again...the very warm and humid air mass will be in play ahead of this extra forcing. This combined with an easily triggered air mass should result in more showers and thunderstorms on Thursday afternoon and evening. Since the best forcing looks to arrive on Thursday evening...we will hold onto pops a little longer on Thursday evening than the past few nights. Overall there remains little change in the air mass. The GFS shows the short wave still exiting the area on Friday Morning as the upper flow is suggested to become more northerly as the day progresses. This is leads to some subsidence in the afternoon in the wake of the upper wave and this is seen within the forecast soundings and the mid and upper levels are considerably dry by Friday afternoon than the previous few days. Pwats fall under 1 inch by late Friday. Thus for now will focus best pops on Friday during the earlier part of the day when upper support is expected to be present. Will trend highs on Friday a bit cooler also as NW surface flow takes shape late in the day in the wake of the upper wave. && .LONG TERM /Friday through Monday/... Issued at 322 AM EDT Tue Jul 7 2020 Models and ensembles agree the ridge will be more compact and over the four corners area on Friday as a sharp upper trough and associated cold front drop southeast across the Great Lakes and Ohio Valley on Friday. The interaction of the trough and very warm, moist and unstable air will result in widespread thunderstorms Friday with lesser chances in its wake Friday night and Saturday. Will have to keep an eye on storm potential on Friday afternoon as much more impressive dynamics than recent times arrive. After that, another trough will move through and bring more chances for unsettled weather to the area Sunday and possibly Sunday evening before and upper ridge brings dry weather to the area early next week. With the cold front to the south and east, prefer the more seasonable blend as opposed to the warmer pre-frontal passage short term temperatures. Look for afternoon highs mostly in the mid and upper 80s through next Monday, although some locales could see 90 degrees on Friday. && .AVIATION /Discussion for 071800Z TAF Issuance/... Issued at 1246 PM EDT Tue Jul 7 2020 VFR conditions expected through the forecast period. More of the same in this stagnant summer pattern that has set up across the Ohio Valley. Cu has popped with the convective temp being met along with widely scattered storms. Both should grow in coverage through the afternoon and will handle simply with a VCTS at all terminals. Any direct impact by convection to a terminal will produce brief restrictions and will update with tempo groups as needed. Skies will clear tonight with loss of heating before doing this all over again on Wednesday. Expect diurnal cu and convection to develop again by midday. Winds will be light and variable throughout the period. && .IND WATCHES/WARNINGS/ADVISORIES... NONE. && SYNOPSIS...Puma NEAR TERM...Puma SHORT TERM...Puma LONG TERM....MK AVIATION...Ryan
