Strong upper level ridging moves in on Wednesday generating high pressure around the eastern Midwest. Temperatures will continue to be in the 70s and increase into the high 70s on Thursday as WAA is brought in from the warms sector of an incoming low pressure system. The cold front will push into the region late on Thursday bringing in rain a isolated thunderstorms if instability is stronger in the region. The SPC has the region under a marginal risk for severe weather due to a high shear/low instability environment. If storms do occur, they will likely be in the form of an MCS and the main threat would be wind gusts. Showers continue into Friday as highs lower into the high 60s. Showers will still continue into Saturday as a secondary center of low pressure moves in behind the low pressure system that creates a larger area of precipitation to fall.
Long term (Sunday 4/21 through Tuesday 4/23)
The upper level flow turns zonal heading into Sunday. Clouds remain in the area due to some low level moisture still be present, but this will also help bring temperatures back up as clouds will provide insulation for diurnal heating. Unorganized upper level ridging moves over the region on Monday allowing for some cloud clearing and WAA. On Tuesday, a shortwave trough will make its way into the Mid-Atlantic adn bring with it a weak low pressure system could possibly bring a short period of rain showers.
