Area Forecast Discussion National Weather Service Indianapolis IN 409 PM EDT Sat Oct 6 2018 .UPDATE... The SYNOPSIS...NEAR TERM and SHORT TERM Sections have been updated below. && .SYNOPSIS... Issued at 329 PM EDT Sat Oct 6 2018 A warm and humid environment will be in place across central Indiana through the weekend and into next week. A persistent frontal boundary will remain in the area with central Indiana on the warm side making the environment very conducive to diurnal development. Some of the storms could become strong to severe this evening and tonight. The pattern will then change around mid-week when a strong cold front moves through the forecast area on Wednesday night. This will result in an abrupt change from the summer like weather back to more normal Fall temperatures late in the extended period. && .NEAR TERM /This Evening and Tonight/... Issued at 329 PM EDT Sat Oct 6 2018 The main focus of the near term period will be the potential for strong to severe thunderstorms with a Slight Risk for severe weather across the northwest two-thirds of central Indiana mainly this evening. Current radar mosaic shows showers and thunderstorms along a strong frontal boundary stretching from Oklahoma through northwest Indiana. This is a strong temperature gradient with temperatures in the mid to upper 80s in the warm sector (central IN) and temperatures in the 60s north of the boundary. So far, some of the storms have been severe, but it has been rather isolated in nature. Nonetheless, the relatively unstable environment with CAPE values in the 1200-1800 J/kg range will make this an area to watch over the next several hours. HRRR showers scattered shower/thunderstorm activity spreading through central Indiana from northwest to southeast through the evening hours, eventually breaking up after sunset. This seems to coincide well with the diurnal threat. So, focus for severe weather will primarily be over the northwest two-thirds of central Indiana over the next several hours...the main threat being damaging winds. Tonight, anticipate the severe potential to wind down after sunset, but there will still be chances for showers and sub severe storms over the northwestern two-thirds of central Indiana once again where forcing is best near aforementioned frontal boundary. && .SHORT TERM /Tomorrow through Tuesday/... Issued at 329 PM EDT Sat Oct 6 2018 Much of the same can be expected for tomorrow. Central Indiana will remain in a warm, moist environment with southerly flow. Once again, the best chances for any showers and thunderstorms will be over the northwest two-thirds of central Indiana...closest to frontal boundary. Meanwhile, the southeastern third of central Indiana can expect mainly dry conditions. However, the drier air will start working its way northward on Sunday night as the high pressure over the Delmarva/Southeast U.S. shifts a bit. So, expect dry conditions over all of central Indiana by Mon 06Z. Monday and Tuesday, the high temperatures in the mid to upper 80s will continue with dewpoints in the 60s. With the aforementioned frontal boundary a little farther north though, shower and thunderstorm chances will be reduced across most of the forecast area. The exception will be low chances across the northernmost counties. && .LONG TERM /Tuesday night through Saturday/... Issued at 256 PM EDT Sat Oct 6 2018 Models and ensembles in reasonable agreement that a strong cold front will move through Wednesday night. Very warm, moist and unstable air along and ahead of the system combined with the strong dynamics will bring widespread showers and thunderstorms to the area next Wednesday and Wednesday night. Heavy rain will be possible. After that, the well above normal airmass will be replaced by a below normal one for late next week and weekend. There will also be a threat for more showers, but models and ensembles are not in good agreement with the timing, so will accept the blend with low confidence in timing. Brought more shower chances in by late next Friday. && .AVIATION /Discussion for the 061800Z TAF Issuance/... Issued at 105 PM EDT Sat Oct 6 2018 A quasi-stationary will slip to near LAF this evening and then remain nearby. Radar was showers numerous showers and a few thunderstorms moving along near the boundary and with an upper wave in southwest flow aloft. Thus, confidence is good enough in tempo MVFR thunderstorm groups at LAF through 03z. Otherwise, less coverage is expected at the other sites. For now, will just go with VFR conditions at the other sites with no thunder mention. But, that may change in subsequent TAF issuances or ammendments. MOre storms may fire up after 15z Sunday, especially in the LAF area, closer to the front. Winds will be southwest 10 to 14 knots with gusts to 22 knots through 23z. After that, winds away from convection or outflow boundaries will see winds drop off below 10 knots. && .IND WATCHES/WARNINGS/ADVISORIES...NONE. && SYNOPSIS...TDUD NEAR TERM...TDUD SHORT TERM...TDUD LONG TERM....MK AVIATION...MK
