Fxus63 kiwx 260549 afdiwx area forecast discussion national weather service northern indiana 149 am edt Mon aug 26 2019 Synopsis Issued at 140 am edt Mon aug 26 2019 periods of rain will be possible today into Tuesday as a slow moving system drags a frontal boundary across the area. An isolated thunderstorm is possible, especially Monday night into Tuesday. High temperatures today will range from the upper 60s to mid 70s and in the upper 70s to lower 80s on Tuesday. Update Issued at 820 pm edt Sun aug 25 2019 low level winds will continue to veer this evening allowing for gradual south to north progression of better low level moisture advection. Weak embedded lead short waves in southwest upper flow will also lift northeast across the region overnight, but very dry low mid level profiles in place initially this evening will take some time to moisten sufficiently for notable precip chances. Have not made many changes to previous forecast with timing the increasing pop chances overnight. Will keep onset of likely pops from southwest to northeast across the area in the 12z-16z timeframe as better low level moisture convergence becomes established with a more defined warm frontal feature lifting northward. Perhaps some very weak elevated instability develops after 12z with this warm frontal feature, but will continue to omit thunder mention at this time due to the forecasted weak nature of the instability. Short term (tonight and Monday) issued at 221 pm edt Sun aug 25 2019 newd pivot of lead convectively augmented SW disturbance over ern ks this aftn will allow warm frontal zone and attendant deep moisture surge to overspread the region on Monday. Leading warm advection wing should focus remain west overnight as predicated in most model guidance. Otherwise showers likely Monday with lead sw

trough warm front lifting through. Long term (Monday night through Saturday) issued at 221 pm edt Sun aug 25 2019 slightly faster consensus solution wrt to ewd cold frontal progression Monday night early Tuesday warrants further pop reductions Tuesday aftn. Poor frontal timing and general cloud contamination should preclude thunder. Thereafter robust post frontal drying cooling spreads across the great lakes oh valley through Thursday. Secondary moisture starved cold front follows Friday before pattern aloft briefly flattens and warms early next week. Aviation (for the 06z tafs through 06z Monday night) issued at 146 am edt Mon aug 26 2019 top down saturation along with low level moisture advection through the period with more widespread rainfall arriving by late morning supports decay of flight conditions as ceiling heights lower into ifr range by midday. Low pressure frontal wave will lift from northern missouri to eastern wisconsin by this evening, placing northern indiana in warm sector which should allow for some improvement in ceiling and more spotty convection for latter part of forecast period.

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.
