Technical Forecast Discussion

Short term (Wednesday 4/24 through Saturday 4/27)

Relatively zonal flow with some areas of ridging in the upper levels will result in pockets of high pressure around the region until the evening. An approaching warm front this evening will bring chances for rain as it is co-located with a mid level disturbance. Clouds will remain low as the warm front moves over bring precipitation from the evening to Thursday morning. Showers continue into Thursday as positive vorticity and deeply layered moisture will allow precipitation to continue while the region is within the warm sector on Thursday. Rain showers will likely be the heaviest Thursday night as this when the most moisture will be in the air as well the strongest vorticity associated with the incoming cold front of the low pressure system. A strong low pressure in the Southern U.S assists with deepening an upper level trough directly over Ohio on Friday. Showers will continue into Friday afternoon as moisture and lift from a secondary cold frontal boundary move through. Synoptic scale subsidence will move in with the left side of the upper level trough Friday night and upper level ridging on Saturday will bring high pressure to clear up cloud cover.

Long term (Sunday 4/28 through Tuesday 4/30)

High pressure leaves the region on Sunday ahead of a weak low pressure system forming from disturbances in the mid levels. Models currently have the cold front of the system moving over the region, but being somewhat dried out. Current model runs only have cloud cover moving in for the latter half of Sunday due to this as well as some CAA. A quasi-stationary front will be push into Ohio early Monday. As the frontal boundary moves closer to the region on Monday afternoon, cloud cover will increase and small chances for precipitation will occur. The stationary frontal boundary will be over the region on Tuesday making rain showers likely. Models have a shortwave trough coming in late Tuesday/early Wednesday that may create a low pressure system for Wednesday.
