#mdwx The current surface map shows a low pressure over the Four Corners with a stationary front across the Tennessee Valley.
This low pressure will eventually be the major player later this week as it develops and moves through the Great Lakes. An unseasonably warm and active pattern will set up starting Wednesday. However, clouds will increase over night with a weak short wave that will move into the area from this west.
The increase in cloud cover will keep our overnight lows seasonable for this time of the year. This short wave and a warm front currently over the Tennessee Valley slowly moving north will allow for a very spotty shower during the day Wednesday. Most of the day and region will remain dry but a stray shower or spotty drizzle will be possible.
The best time for the shower looks to be in the morning as the short wave moves through. High temperatures Wednesday will depend on how much sun can break through the clouds.
The best chance of seeing sunny breaks will be in the afternoon.
