882 FXUS63 KIND 021648 AFDIND Area Forecast Discussion National Weather Service Indianapolis IN 1148 AM EST Mon Nov 2 2026 .KEY MESSAGES... - Low clouds and patchy drizzle expected at times through today - Warmer than normal temperatures continue through mid week - Rain chances return Tuesday night with a few rumbles of thunder possible - Cooler but still near seasonal normals late week into the weekend && .FORECAST UPDATE... Issued at 917 AM EST Mon Nov 2 2026 No major changes needed to the ongoing forecast with conditions generally evolving as expected. ACARs soundings near IND continue to show near surface saturation with drizzle reported across much of the forecast area. This saturation is expected to persist through the early afternoon with dew point depressions gradually increasing after 20Z. This lines up well with the forecast which had drizzle tapering off from west to east after 20Z. With the thick stratus and drizzle, temperature rises have been a bit slower than initially expected, but with the gradual lifting of cloud bases and strengthening southerly flow, highs in the low to mid 60s still seem reasonable at this time. && .DISCUSSION (Today through Sunday)... Issued at 302 AM EST Mon Nov 2 2026 Cooler but still near to above normal temperatures are expected this week along with an active stretch through mid week. A couple of weak upper level waves moving through the area today will continue to promote widespread low cloud cover and occasional patchy drizzle owing to weak forcing and shallow low level moisture remaining in place across the area. This will limit diurnal temperature range with lows this morning likely no cooler than the low to mid 50s, and highs this afternoon eking out a modest recovery into the low to mid 60s. Some breaks in the cloud cover are expected later tonight into Tuesday, which, along with good low level mixing and strong warm advection ahead of a potent approaching mid week system will push temperatures to their warmest of the forecast period on Tuesday, with highs likely well back into the 70s. This reprieve will be brief, however, with a cold front poised to push steadily through the area late Tuesday night into Wednesday, producing widespread showers and perhaps a few embedded rumbles of thunder, with lingering precip likely to taper off late Wednesday. Forecast profiles continue to depict very strong deep layer shear but functionally zero upright instability, which will largely eliminate any sort of organized severe threat, although there is always the concern that a stronger shower could briefly mix down some stronger gusts to the surface as a 50-60KT low level jet traverses the area with the boundary. Outside of showers, synoptic winds will be fairly strong ahead of and immediately behind the boundary Tuesday into Tuesday night, with gusts of 35-40+ MPH possible. Conditions will turn cooler again in the wake of the front, though will still be near seasonal normals, with highs toward the end of the period in the upper 50s to low 60s and lows in the mid 30s to mid 40s. A few periods will need at least slight chances for showers as models depict the large scale upper low slowing and pivoting over the Great Lakes and eastern CONUS late week into early next week, and likely another upper level disturbance pinwheeling around or being absorbed into the larger scale low, which may bring additional showers and perhaps reinforcing shots of cool air to the area. && .AVIATION (18Z TAF Issuance)... Issued at 1148 AM EST Mon Nov 2 2026 Impacts: - High IFR and low MVFR cigs to improve to VFR during the overnight hours - Lingering MVFR to IFR vsbys due to drizzle to improve to VFR after 20Z - Southerly wind gusts up to 25kt after 12Z Tuesday Discussion: Low level saturation persists across central Indiana leading to continued drizzle and low cigs. These conditions will improve this evening into the overnight hours as dew point depressions begin to increase as a response to drier air advecting in at the low levels. Conditions should improve to VFR around 00Z but there are some signs that low clouds may stick around into the early overnight with some question how extensive they will be. Marginal LLWS conditions are likely towards daybreak as the LLJ ramps up ahead of the Tuesday night system, but should remain brief enough to not warrant a mention in the TAF. Southeasterly winds will become more southerly late tonight with gusts up to 25kt after 12Z tomorrow. && .IND WATCHES/WARNINGS/ADVISORIES... None. && $$ UPDATE...White AVIATION...White DISCUSSION...Nield
