Technical Forecast Discussion
Short term (Sunday 11/18 through Tuesday 11/20)
Clouds will move through tonight as the low pressure system moves through. A stream of moisture is present at 700mb currently, but lacks forcing for the first part of Sunday. As an upper level trough positions itself downstream of the region, divergence above should be enough to kick start upward motion and bring in precipitation for the late evening today as the cold front moves through. As Monday approaches, the upper level trough will have its axis over the region. Low pressure hangs around Ohio on Monday that allows moisture to continue to move through the region, making rain showers a continuous occurrence for Monday. Sinking motion moves in over the region early Tuesday which will clear precipitation while some clouds remain over the region for the rest of the day and evening.
Long term (Wednesday 11/21 through Saturday 11/24)
Ridging approaches the region on Wednesday as a dry cold front will move through for the later half of the day. Moisture will be aloft, but upper level conditions are not favorable for precipitation and likely only generate cloud cover for from the afternoon to the evening on Wednesday. With the ridge still making its way into the region, it will promote high pressure for the area on Thanksgiving Day as cloud cover finally clears across the state. As Friday approaches, high pressure will stay in the region until a shortwave trough moves in during the late evening. This will produce rain showers into Saturday as more upper level disturbances are present for Saturday.
