It was a quiet and cool (albeit pleasant) start to the week throughout the Tri-State; many of us dealt with our fair share of sunshine and seasonable afternoon highs in the mid 50s. The mercury is expected to dip back into the upper 30s and low 40s area wide as more cloud cover settles in across the region overnight, keeping conditions quite calm overall for our Tuesday ahead. The mercury will only reach the mid to upper 50s yet again - Evansville will tip the scales at 57° tomorrow afternoon. This calm weather however, is expected to give way to not only a more active forecast in the near future, but also the threat of Severe Weather as well.
We're closely watching a complex of low pressure currently situated over the Rockies that looks as though it will supply parts of the Plains, Mississippi Valley, Southeast and the Midwest with the threat for Severe Weather during the next 72 hours or so. Our first chances of rainfall will reach the Tri-State late Tuesday evening before settling in in a more sustained fashion overnight and into the predawn hours Wednesday.
The rain will continue into Wednesday morning's commute and will likely intensify from there - there's a possibility we may see periods of strong winds associated with some of those sustained showers and early morning thunderstorms between 6AM and 10 AM. The greatest threat of inclement weather won't arrive however until 11AM or 12PM on Wednesday. It's at that point in which the advancing cold front and a strong upper-level jet will begin to pass directly over the Tri-State.
The combination of some warmer air at the surface (around 65°), the passing cold front and strong winds aloft could, not only intensify storms forming at the surface, but also generate brief periods of rotation within some of those storms. In addition to the damaging wind threat on Wednesday morning and afternoon, isolated tornadic rotation looks in play between the hours of 11AM and 7PM on Wednesday. It'll be an active day to say the least, but with all the preparations that go into Thanksgiving, it might be easy to forget about our impending threat of Severe Weather, so please remember to remind yourself to remain weather aware on Wednesday.
