Fxus63 kiwx 220807 afdiwx area forecast discussion national weather service northern indiana 407 am edt Thu aug 22 2019 Synopsis Issued at 150 am edt Thu aug 22 2019 a cold front will drop south through the region overnight with chances for showers and a few thunderstorms along it. A chance of thunderstorms will continue into Thursday, along and south of a monticello to wabash to lima ohio line. It will be cooler and less humid Friday and Saturday with mostly clear skies providing comfortable conditions for late august. Short term (today and tonight) issued at 316 am edt Thu aug 22 2019 a cold front was moving south across northern indiana early this morning and was accompanied by showers and a few thunderstorms. Overnight convection in rich theta E air with precipitable water values between 1.6 and 1.8 inches per SPC analysis was able to generate some rather substantial rainfall amounts in northwest ohio of over 3 inches in 2 hours given adjusted radar estimates. Any local flooding in the area will diminish early this morning as a large storm complex over southern indiana limits moisture flux into the area today. The NAM has had very poor run to run consistency with the latest run 00z finally appearing to be on track and keeping heavier rain close to the ohio river. Have kept chances for showers and storms along and ahead of the front today, with all showers and storms moving south out of the forecast area early tonight. Temperatures will be well below normal today with highs around 75. Lows tonight will drop well down into the 50s over most areas as the intrusion of canadian air increases. Long term (Friday through Wednesday) issued at 316 am edt Thu aug 22 2019 the well advertised cool, less humid and dry period is just ahead

as the center of a high pressure area settles near james bay early this weekend. Highs will be in the 70s through Sunday with lows falling into the 50s each night. A more active period is taking shape Monday as moisture surges back north across the ohio river in response to a positively tilted upper trof digging into the upper great lakes region. Ample moisture will be available for showers and storms with precipitable water values topping 2 inches Monday night. Have trended up rain and storm chances during this period. Aviation (for the 06z tafs through 06z Thursday night) issued at 152 am edt Thu aug 22 2019 weak west to east tracking impulses ahead of southward sagging frontal boundary providing impetus for isolated to scattered convection across northern indiana overnight. With better, albeit modest instability pool, 500 j kg mlcape, and collocated effective shear on order of 30-35 kts near and east of kfwa, could not rule out an early morning tsra event, though chances of occurrence quite low too low for inclusion at this time. Suspect a brief period of higher end MVFR with mid late morning cumulus field formation, otherwiseVFR conditions prior and after. Another chance of mid late afternoon convection exists, though best area of concern lies just south of kfwa and will forgo any mention in terminal forecast at this time.

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.
