Technical Forecast Discussion

Short term (Sunday 1/27 through Tuesday 1/29)

On Sunday, a stationary system exists out in the Eastern Plains with another low pressure system to the North in the Ontario area. These two systems create widespread instability and lift all around the area and with the 700mb RH showing high values and the moisture looking relatively deeply layered all together, precipitation is likely to occur Sunday as a mixture of snow and rain. Nearing Monday, a jetstreak over the Central Plains interacts with the stationary front and begins to produce a low pressure system. As this system picks and and the upper level patterns morphs into a trough, a stationary frontal boundary will rest over Southern Ohio Monday that is likely to continue precipitation. Depending the exact positioning of the model will determine snow or rain as the main precipitation form. The system’s cold frontal boundary will pass over Tuesday. Rain and snow are likely until the later half of the day when cold, dry air moves behind the front.

Long term (Wednesday 1/30 through Saturday 2/2)

The cold front will be well pass the region on Wednesday as a scenario for a cold wave begins. Cold, dry air is pushed into the region due to the troughing allow cold air to move southward. Moisture will begin to be removed late Wednesday as dry air from the cold front pushes it out. There is a likelihood that lows will be below zero on Wednesday as the center of the cold mass nears the region. Upper level ridging begins to move into the region on Thursday as cold air remains. The encroachment of ridging will promote cloud clearing through Saturday as temperatures will drastically increase Friday through Saturday.
