Today through Wednesday, an upper level trough will cause a frontal system to continue to be in place over the area, which will enhance rain chances. This system will still be stalled through this time period. And there is plenty of moisture in the environment as evidenced by higher Precipitable Water values. As a result, there is the potential for training storms to develop, resulting in the potential for heavy rainfall. Some areas that have already received rainfall in previous days are at an increased risk of flooding. In addition to the rainfall risk, there is also a threat of gusty winds and frequent lightning with any stronger storms that develop along this front.
Thursday and Friday, rain chances are lessened due to the presence of a high pressure system that will be in place. Southerly surface winds will help to enhance the moisture in the environment during these days however. Consequently, some showers and storms are still possible during the afternoon hours these days, but at lesser coverage than previous days.
Saturday and Sunday, a shortwave trough is expected to move through the area. As a result, rain chances will increase, especially on Sunday. There will be plenty of moisture in the environment due to southerly surface winds. Upper level divergence will also act to enhance lifting in the environment. Any storms that develop will likely have the potential to produce heavy rainfall, gusty winds, and frequent lightning.
