Area Forecast Discussion National Weather Service Northern Indiana 325 PM EDT Thu Sep 24 2020

SYNOPSIS. Issued at 129 PM EDT Thu Sep 24 2020

Warm and dry weather continues through the weekend. Much cooler temperatures and a better chances of showers spread into the area

SHORT TERM. (This Evening through Saturday Night) Issued at 319 PM EDT Thu Sep 24 2020

Weak upper level wave was dropping through Minnesota and WI, heading towards the area this evening. Currently some showers/storms with it, but showing signs of weakening. Wave will continue to dampen and run into much drier airmass (PWATs generally AOB 1 inch) so no hope for any rain. Also, remnant MCV with these storms will probably drift across MI. Some left over cloud cover may drift across, but should mainly be mid/high and not pose much impact to the area.

The departure of this wave and approaching deeper northern stream trough will starting sending 850 mb temps soaring, not so much Friday but Saturday looking warmest with highs well into the 80s. As mentioned in past, no precip to worry about with front that will be just to our west. Saturday night looking bleak as well so will be going dry.

LONG TERM. (Sunday through Thursday) Issued at 319 PM EDT Thu Sep 24 2020 Big pattern change starting next week as energetic NW flow begins to establish across the central/eastern US. Series of waves will move out of the NE Pacific and help carve out deep upper trough that will push a strong cold front across the region late Sunday into Monday. If any rain chances exist, it will be with this system and series of waves behind it in cold NW flow. Mid range chc pops warranted for mainly Sunday night into Monday, but not a good soaker of rainfall.

Models diverge on handling of James Bay energy and additional waves moving through, with 00Z EC the most aggressive cutting off a low into the southern stages and then returns north to rephase with a bunch of gulf moisture and maybe a cold rainfall for the area with 850 mb temps dropping below 0C. GFS doesn't cut off the low this far south but still parks over the Great Lakes and not as aggressive with cooling 850 temps. Model blend remains conservative at this point, but temps will be well below normal by Tuesday with highs only in the 50s and maybe some lake effect rain showers possible depending on exactly how cold we get. With colder air aloft, should be plenty of instability to see maybe some convection (graupel/small hail) with showers. Something to monitor. Can't rule out some frost concerns either.

AVIATION. (For the 18Z TAFS through 18Z Friday Afternoon) Issued at 129 PM EDT Thu Sep 24 2020

VFR conditions persist through the period. FEW/SCT CU field will erode near sunset.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
