6/19 – Rob’s “Drier” Wednesday Morning Forecast

0

An upper level disturbance moved NE last night, but the moisture flow will continue through the weekend. As a result, a few showers and an isolated thunderstorm will be possible today, but much…much less activity than yesterday. Another upper level disturbance is expected to fill in behind the current system and will begin to influence the area overnight into Thursday. Upper level divergence will cause lifting in the atmosphere again. There will continue to be high moisture presence in the atmosphere as a result of the southerly winds. Because of the high moisture and lifting in the atmosphere, showers and a possible thunderstorm will be possible Thursday morning through Thursday evening.

A high pressure system is then expected to build over the area Friday through Sunday. Upper level convergence from this system will cause sinking air and stability in the atmosphere. There is still a high moisture presence and lifting in the environment through the weekend, however. Consequently, a shower or two is still possible during the daytime heating hours this weekend, especially Friday. At the beginning of next week, a weak upper level trough will build over our area again, and the chance of showers will increase slightly as atmospheric stability decreases from this system. A few showers and a possible thunderstorm are expected Monday through Tuesday.
