Technical Forecast Discussion
Short term (Wednesday 2/20 through Saturday 2/23)
An upper level trough is visible over Eastern Mid-West. This will allow for the similar scenario from past weeks of a ridge/trough pattern that allows for upper level air to pull up moisture from and around the gulf that creates precipitation potential. Rain showers will be likely on Wednesday as a low pressure system moves into the region in the morning providing substantial lift for precipitation to fall. Upper level ridging will help push dry air behind the cold front that is currently impacting the area. This will bring clearer skies and highs in the mid to high 40s. Conditions will remain relatively stable for the first half of Friday as high pressure forming over the Central Plains moves over the Great Lakes. A shortwave trough form over the Pacific U.S and quickly moves through the long-wave pattern into the region late Friday. The presence of the shortwave trough will allow for moisture to rise up from the southern U.S. This moisture will react with lift from the shortwave to create precipitation for Southeast Ohio through Saturday. This shortwave also create a low pressure system that pushes through early Friday with the warm front being the main area of rain for Saturday.
Long term (Sunday 2/24 through Tuesday 2/26)
By Sunday morning, most moisture associated with the low pressure system should be to the east of the region. WAA from the warm front on Saturday will still be evident as highs near 60 degrees. Another cold front attached to the low pressure system will move through the middle of Sunday. This front will be largely dried out resulting in another clearing of moisture and CAA. This will result in a dip in highs for Monday reaching only the low 40s. The upper level pattern during this two day span will begin to flatten out and take on a zonal appearance. This will promote relatively stable conditions for the southern half of Ohio through the end of Monday. Upper level troughing upper north strengthens and begins to shape the whole of the long wave pattern over the Midwest on Tuesday. Models show only weak perturbations as of now, but this could be enough to generate moisture and a chance for rain showers.
