Area Forecast Discussion National Weather Service Indianapolis IN 552 PM EDT Mon Jun 22 2020 .UPDATE... The AVIATION section has been updated below. && .SYNOPSIS... Issued at 316 PM EDT Mon Jun 22 2020 A frontal system will be moving through the area tonight, bringing with it rain and chances for damaging winds and possibly hail this evening. Surface high pressure will then lead to a mostly dry period midweek, broken up by a possible short wave Wednesday. Another system will then lead to a warm, rainy period again next weekend. && .NEAR TERM /This Afternoon and Tonight/... Issued at 316 PM EDT Mon Jun 22 2020 Isolated and sometimes small lines of storms will continue through the afternoon hours ahead of an approaching cold front. The front itself will move across the area overnight from west to east. Rain will become more widespread along and ahead of the front later this evening. Models look to pretty much agree on the timing of the front, showing that it will likely reach the eastern edge of the forecast area by tomorrow mornings commute. Expect rain to be heavy at times as PWATs range from 1.5 to 2, which is above normal for this area, even during this time of year. There is also a chance of damaging winds and hail with these storms, especially for the W and NW counties, which are near where the best forcing will be with this system. From mesoanalysis, low level lapse rates could exceed 8 C/km in areas while CAPE looks to be 2500 to 3000 J/kg. This is a good environment for higher winds, possible downbursts, and hail. Given the overnight rain, low temperatures look to only get down to the upper 60s. && .SHORT TERM /Tomorrow through Thursday/... Issued at 316 PM EDT Mon Jun 22 2020 The cold front will be exiting the forecast area Tuesday morning, which could still have some lingering showers behind the front and on the backside of a surface low through the afternoon hours. Surface high pressure will start to build in from the SW Tuesday night allowing for a period of mostly dry weather into Thursday. The exception would be sometime Wednesday, where models are hinting at a short wave possibly bringing in a chance of rain for the NE half of the forecast area. As the surface high treks eastward, return flow on the backside of the high could bring possible light PoPs at the tail end of the short term , but this will largely depend on how quick or slow the high moves - at the moment going with guidance on slight chance of rain in the far NE Thursday afternoon. Aloft, there will be W to NW flow, which will help keep temperatures slightly below normal with highs near 80 and lows near 60. && .LONG TERM /Thursday Night through Monday/... Issued at 213 PM EDT Mon Jun 22 2020 Into the sweatbox we go. ECMWF suggests a strong area of high pressure setting up across the southeastern United States during this period. This will result in a continue flow of warm and humid gulf air into the Ohio Valley and Indiana during the period. Dew points this weekend are suggested to get into the lower 70s...which is quite humid. Meanwhile aloft West to NW flow looks to remain in place with little in the way of upper support expect on Saturday night when a quick moving short wave associated with a cold front moving through the Great Lakes. At this point...this looks like the best chance for rain during the period...however on Day 5...timing may adjust between now and then. Otherwise the NBM kept small chances for rain in each day during the extended period. This is due to the combination of Daytime heating and the very warm and humid air mass expected across the area. Given this...daily hit and miss afternoon showers and storms are possible. && .AVIATION /Discussion for the 230000Z TAF Issuance/... Issued at 552 PM EDT Mon Jun 22 2020 VFR conditions are expected to deteriorate to MVFR and worse after 05z-07z and in heavier thunderstorms. South and southwest winds to near 10 knots away from thunderstorms will shift to west and northwest after 11z-16z in the wake of the cold front. Wind speeds then will increase to 10 knots or more with gusts to 20 knots. && .IND WATCHES/WARNINGS/ADVISORIES... NONE. && SYNOPSIS...KH NEAR TERM...KH SHORT TERM...KH LONG TERM....Puma AVIATION...MK
