.SHORT TERM…
Issued at 327 PM CDT Tue Oct 18 2022

Through Wednesday night…

A cut-off and vertically stacked low pressure system centered over the vicinity of eastern Lake Huron and Georgian Bay continues to dominate the weather pattern across the Great Lakes and northeastern CONUS this afternoon with an expansive comma-shaped cloud shield spanning from the western Great Lakes to a few hundred miles off the Atlantic coast. While we find ourselves on the western terminus of this cloud shield, this low`s influence is still very much being felt in other ways in our CWA, predominantly in the form of blustery northwest winds resulting from the compact low-level pressure gradients between the low and a region of high pressure over the Great Plains. These winds — frequently gusting in excess of 30 mph — are expected to continue into this evening before slowly abating and becoming less frequent overnight. Prior to that occurring, the combination of these northwest winds and the high waves that they are causing may result in minor lakeshore flooding along the northwest Indiana shoreline.

Additionally, multiple bands of lake effect precipitation are evident along the eastern half of Lake Michigan on regional radar mosaics this afternoon. Lake effect parameters are not nearly as impressive as they were yesterday, but should remain sufficient to allow for this precipitation to continue for several more hours. Most of this precipitation will remain east of our CWA, but Porter County (and perhaps portions of neighboring Jasper and Lake counties) is positioned favorably to at least see intermittent light precipitation pass over portions of the county through this evening and possibly into the overnight hours as well. Thermodynamic profiles suggest that rain will be the favored precipitation type for the most part, but snowflakes could mix in or become the outright precipitation type as cooler temperatures set in tonight. Either way, not expecting any impacts with this given how light the precipitation will be.

Overnight temperatures will fall below freezing across most of the CWA tonight with only the innermost portions of the Chicago metro and portions of Lake and Porter counties in Indiana likely seeing low temperatures remain above the freezing mark. Wednesday will be another unseasonably cool day with highs expected to peak in the mid to upper 40s, for the most part, despite mostly sunny skies as the residing Canadian air mass remains more or less in place. Winds are not expected to be quite as blustery as they were today with the surface pressure gradient relaxing in response to the weakening of the aforementioned occluding surface low to our northeast. Low temperatures on Wednesday night then look to range from the mid 20s to the mid 30s.
