Fxus63 kiwx 210824 afdiwx area forecast discussion national weather service northern indiana 424 am edt Wed aug 21 2019 Synopsis Issued at 153 am edt Wed aug 21 2019 a cold front will drop south through the region today with a chance of showers and thunderstorms, mainly south of route 24. The front will stall south through central indiana on Thursday with a weak system moving through to bring a chance of showers. Otherwise, cooler and less humid weather is in store for Thursday through Saturday. Short term (today through Thursday night) issued at 341 am edt Wed aug 21 2019 a cold front was over wisconsin and was moving southeast. A line of showers was associated with the front and will move southeast today. Ahead of the front, areas of fog had developed where skies had cleared with visibilities generally between 1 and 3 miles north of a line from rochester to warsaw to hillsdale. The fog has been locally dense in a few spots, but is not expected to become widespread dense fog. The fog will mix out after daybreak and should not be an issue later this morning. Otherwise, the convective allow models were really holding back on showers and storms today in lieu of development tonight over southern areas. This south area should stay active Thursday as a wave develops along the front given a scenario that is supported by the NAM and also by the ecmwf. Any storms should end by midnight, although lingering showers may persist until close to daybreak Friday morning.

Long term (Friday through Tuesday) issued at 341 am edt Wed aug 21 2019 a large surface high pressure area will build in from canada late this week and bring 3 days of fair skies with cool, dry and less humid conditions from Friday through Sunday. An unsettles period is ahead early next week as warmer and more humid air spread back into the region with shower and storm chances beginning Monday. Aviation (for the 06z tafs through 06z Wednesday night) issued at 157 am edt Wed aug 21 2019 continued concern for early morning period of ifr flight conditions at ksbn and kfwa. At ksbn the more shallow nature of moisture and greater radiational cooling potential, per satellite trends, suggests that br a greater concern over low stratus layer. At kfwa stratus remains a concern given... Later clearing, upstream 1500 ft cloud layer and 10-15 knots flow mixing in boundary layer per latest hrrr and rap soundings. Bottomline is tempo ifr forecasts remain intact. Low chance for showers thunderstorms midday afternoon remain too low for mention at this time. Iwx watches warnings advisories In... None. Mi... None. Oh... None. Lm... None. Synopsis... Murphy short term... Skipper long term... Skipper aviation... Murphy visit us at

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
