Following a pleasant stretch of drier and cooler weather, scattered rainfall has returned to the Tri-State. A core of low pressure pushing northeastward across the Mississippi Valley and into the Ohio Valley will prolong our chances of rain and cause them to linger though the remainder of the evening and even into our Wednesday. Be sure to grab the umbrella as you head out the door tomorrow as scattered showers and thunderstorms will likely affect the region though your morning commute. However, a break from the rain is expected by our lunch hour - this will allow temperatures to surge toward the mid 70s tomorrow afternoon, fueling additional pop-up showers and thunderstorms beginning between 3PM and 4PM Wednesday.
Clusters of showers and thunderstorms developing ahead of the advancing core of low pressure may quickly intensify late tomorrow afternoon and early evening. Storms will continue to strengthen through 8PM or 9PM - some of the cells embedded within these clusters may produce wind gusts in excess of 50 mph along with brief periods of broad rotation - as a result, our greatest threats from these storms will be damaging straight-line winds and brief tornadoes. Due to the threat for potentially Severe Weather, the Storm Prediction Center has placed the majority of the region under a "1" on the Threat Index for late Wednesday afternoon and evening. The timeline for tomorrow's potentially strong storms will occur from 4PM through 12AM Thursday.
It looks as though a few scattered showers and possibly an additional thunderstorm or two may linger into our Thursday morning and early afternoon. With the low on its way out of the region by Thursday afternoon, rain chances will exit east of the Tri-State and current model data suggests that a period of drier and warmer weather will arrive that evening. With temperatures in recent days even struggling to climb above the 70° mark, the added sunshine and clearer skies will push temps into the 80s for Friday and Saturday. Make sure to make the most of the drier weather while it lasts, scattered showers and thunderstorms are expected to return by the end of the weekend.
