580 FXUS63 KIWX 230650 AFDIWX Area Forecast Discussion National Weather Service Northern Indiana 250 AM EDT Wed Aug 23 2017 .SYNOPSIS... Issued at 246 AM EDT Wed Aug 23 2017 Cooler and less humid conditions will prevail through the next several days across the region. Highs today will be in the middle to upper 70s and lows tonight in the upper 40s to lower 50s. Highs may struggle to get above 70 in some areas on Thursday. The next chance for any measurable precipitation doesn't arrive till possibly Monday && .SHORT TERM...(Today and Tonight) Issued at 246 AM EDT Wed Aug 23 2017 High pressure will begin to take control of the region today with cooler and much less humid conditions. Enough residual moisture will exist to allow for cu field to pop late morning into this afternoon, but dry conditions will remain. Highs will be in the lower to middle 70s with locations along the lakeshore barely touching 70 with the NW flow off the lake. Skies will clear out for most locations for tonight. However, approaching disturbance out of Minnesota will bring enough moisture and cold air aloft to allow for some lake effect cloud cover. Still not expecting much more than partly cloudy skies closer to the lake. && .LONG TERM...(Thursday through Tuesday) Issued at 246 AM EDT Wed Aug 23 2017 Upper level disturbance will ride the edge of the ridge bringing increased clouds to much of the area, especially Thursday morning. Cold air aloft will allow for a pocket of steep mid level lapse rates (6.5-7 C/KM) which could stir up a few light showers near the lakeshore areas as well as isolated waterspouts over the nearshore waters. Will leave forecast dry for the time being given, but may need to introduce at least some slgt chc pops in Berrien/LaPorte counties. Will be a raw day by late August standards with some locations not even getting close to 70, especially closer to the lake. Quiet conditions then settle in through the bulk of the period with the next trough beginning to edge towards the area from the west Mon/Tues. All models shows spurious QPF from any number of factors over the area. Confidence remains low if pops will even workout, especially Monday. Will go ahead and hold onto pops for Mon-Tues with diminishing trend Monday night with loss of daytime heating. Exact impacts from what is expected to be remnants of Harvey plus potential east coast tropical system remain to be seen. && .AVIATION...(For the 06Z TAFS through 06Z Wednesday Night) Issued at 114 AM EDT Wed Aug 23 2017 VFR conditions expected through the period. Patchy strato cu at base of inversion aloft continuing over nrn IN/swrn MI attm and may persist overnight. Radiational cooling will saturate near sfc layer early this morning but moisture very shallow, so no vsby restrictions fcst. Sufficient lingering low level moisture/instability for sct cu at fwa later today, while areas near Lake Michigan should be a little more stable resulting in skc at sbn. && .IWX WATCHES/WARNINGS/ADVISORIES...
