8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it. 8/18/2020 NOAA continues to have trouble.

Area Forecast Discussion National Weather Service Northern Indiana 1227 PM EDT Fri Sep 18 2020
SYNOPSIS. Issued at 249 AM EDT Fri Sep 18 2020
Much colder temperatures will be felt into the weekend with temperatures much below normal. Highs today will only be in the 60s, and lows tonight will fall into the 30s, with potential frost. Temperatures will start to rebound on Sunday, and warm through mid-week. The next chance for rain will be Thursday.
SHORT TERM. (Today and Tonight) Issued at 249 AM EDT Fri Sep 18 2020
Cold upper level troughing and surface high pressure will keep the area cool yet dry today, with highs only in the mid 60s. Winds will be northeast and slightly breezy, but will diminish to around 5 mph after sunset. These light winds and clear skies will combine to produce good radiational cooling conditions, and temperatures are expected to fall into the 30s across the forecast area. Frost will therefore be possible, especially to the northeast, and a Frost Advisory is being issued for late tonight into Saturday morning.
LONG TERM. (Saturday through Thursday) Issued at 249 AM EDT Fri Sep 18 2020
Upper troughing will start to shift east on Saturday, and high pressure ridging will build in from the southwest going into the first part of next week. Temperatures will gradually warm during this period, getting into the upper 70s to near 80 by Wednesday, with dry conditions persisting. Troughing returns on Thursday with models bringing a shortwave into the region. There is still a lot of uncertainty though with model differences in location and amount of moisture. Decided to keep the slight chance of showers supported by the NBM and Canadian, although this may end up being another mostly dry front.
AVIATION. (For the 18Z TAFS through 18Z Saturday Afternoon) Issued at 1227 PM EDT Fri Sep 18 2020
North-northeast winds near 10 knots this afternoon will veer more easterly and diminish tonight. Remaining VFR/dry otherwise with little in the way of cloud cover.
