Technical Forecast Discussion
Short Term (Thursday 4-27-23 through Sunday 4-30-23)
The southeast Ohio region is still residing underneath upper level ridging and surface high pressure, providing sunny skies and mild temperatures for much of this Thursday. However, the weather pattern will soon change as a shortwave trough and surface low pressure system make their approach from the southwest. This dynamic system will bring rounds of showers and thunderstorms to the region, which unfortunately means a wet end of the work week and weekend ahead. All of southeast Ohio is currently under a marginal risk for both excessive rainfall and severe weather on Friday (see Hazardous Weather Outlook), with damaging winds and heavy downpours being the main threats. Some heavy downpours may produce localized flooding concerns, particularly in low-lying areas. A brief break in precipitation will occur during the day on Saturday as the low pushes off to the northeast, but another round of showers will arrive Saturday night thanks to shortwave energy affecting the area. Sunday additionally will feature the continuation of showers as a larger trough moves over the Great Lakes. This trough will feature another low pressure along with it, and will remain rather stationary heading into the next week.
Long Term (Monday 5-1-23 through Thursday 5-4-23)
The previously mentioned longwave trough and low pressure system will remain rather stationary over the Great Lakes to start out the new work week, providing even more rounds of showers. The trough and low pressure system will gradually make their way northeast, finally pushing out of our region. The rest of the long term forecast looks quiet as high pressure builds back in, providing clearing skies and a gradual warming trend throughout the week.
