High Pressure Briefly Gains Control

High pressure remains in control for Tuesday, allowing skies to remain mostly sunny and temps to climb into the lower 50s!
Wed-Thu
High pressure slides east during the day on Wed, which will allow clouds to thicken and showers to develop. A vigorous area of low pressure will really begin to intensify shortly after developing in the Gulf of Mexico. After formation, the low will begin sliding NNE towards the Ohio Valley. Given its origin, the storm will have a lot of moisture to work with. Consequently, expect widespread rain to develop by Wed afternoon/evening, continuing through the night. Some of the rain may be heavy, so take it slow when driving, and watch out for ponding. Temps on Wed will only climb into the 40s before falling into the middle 30s overnight. For Thu, temps will really begin the drop, with highs only topping out in the upper 30s. I wouldn’t rule out a few flurries or snow showers, though they will be isolated and light. Temps really fall off Thu night with most areas expected to bottom out in the middle 20s.
Fri-Mon
The chill really sets in for Fri, Sat, and Sun. The strong cold front associated with the Wed/Thu system will really help usher in the cold air, which will easily be the coldest we’ve seen since last winter. The setup for LES (Lake-Effect Snow) will also be very favorable, so areas to our north (in the classic belts) look to receive their first significant accumulating snow of the season! As is always the case, if the fetch is favorable, we may see a scattered flurry or snow shower in portions of the tri-state, though they will be few and far between (especially for areas south of I-70). Most of the LES will fall on Fri, though some of the belts will still be cranking on Sat as well. Expect temps to struggle to make it to the freezing mark for both Fri and Sat, with lows both nights falling into the middle/upper TEENS! Temps begin to moderate a bit for Sunday with highs topping out in the middle 30s. The moderation continues for Monday with high temps topping out around 40.
