Technical Forecast Discussion
Short Term (Thursday 4-13-23 through Sunday 4-16-23)
Upper level ridging and surface high pressure has been dominating the southeast Ohio region the entire week, providing abundant sunshine and temperatures in the upper 70s to low 80s. Thursday was another beautiful day due to this pattern, but we will see chances for precipitation return Friday afternoon as a shortwave trough and surface low pressure system approach from the south. This will lead to increasing clouds in the morning on Friday, with rain shower chances arriving by the afternoon/evening. Brief rumbles of thunder will be possible as well. This more active weather pattern will continue throughout the weekend as a longwave trough approaches from the west, sending a cold front through on Sunday. After the frontal passage, winds will be rather gusty out of the N/NW due to a tightening pressure gradient.
Long Term (Monday 4-17-23 through Thursday 4-20-23)
Some lingering showers will be possible on Monday as the shortwave trough and surface low pressure system push off to the northeast. As mentioned in the short term discussion, winds will be quite gusty after the cold frontal passage. Upper level ridging and surface high pressure will then take hold once again by Tuesday, providing a gradual warming trend in temperatures and returning sunny skies for the remainder of the long term period.
