Technical Forecast Discussion
Short-Term Forecast (Sunday 12/3/2023 through Tuesday 12/5/2023):
A series of upper-level shortwaves are anticipated to move through the region over the next several days, bringing multiple rounds of showers. Starting this evening and into the overnight hours, scattered are expected throughout the region, bringing on and off rain. Monday morning, a break from the rain is expected before another shortwave propagates a weakening line of showers into the area during the afternoon/evening hours. No measurable precipitation is expected from this round of storms.
Tuesday, a positively tilted longwave trough will dip into the region, bringing significantly colder air. SE Ohio is positioned along the snow/rain line, so we will likely see mixed precipitation when the storms enter the region Tuesday morning. Up to 0.2 inches of accumulated precipitation is expected. By Tuesday night into Wednesday morning, the remaining showers are anticipated to drop a few snowflakes as temperatures drop below freezing.
Long-Term Forecast (Wednesday 12/6/2023 through Saturday 12/9/2023):
Wednesday afternoon, significant ridging will build in behind the last system. Skies will become mostly clear – the first time in multiple days. Thursday and Friday, significant WAA will occur, allowing for afternoon highs to warm into the mid-to-upper 50s, which is well above average for this time of year, per the Climate Prediction Center. Saturday, another shortwave will propel a system into our region. Widespread showers and a drop in temperatures are anticipated.
Synopsis:
Sunday – Wednesday morning: Cold and rainy.
