After tomorrow's mostly sunny day and relatively nice temperatures, we go back downhill as we work through Thursday afternoon and Friday. A storm system currently over the Midwest will work east and spread showers and storms into our region during the afternoon from southwest to northeast on Thursday afternoon. While the day may start sunny clouds will be on the increase, with showers and some rumbles of thunder moving in during the afternoon hours. The GFS (above) shows precipitation moving in on Thursday and over the region for the evening rush.
This system is a slow-mover -- it will lurk over the region for Thursday PM, Friday, and early Saturday before finally fizzling as it pulls off the coast. While it will not rain the entire time over that 48 hour stretch, there will be rounds of showers and scattered storms around the area, more numerous with Thursday afternoon's entrance of precipitation into the region and again on Friday afternoon with the influence of daytime heating on the atmosphere. Some precipitation may linger into early Saturday but computer guidance is split on whether any showers pop up or linger around, between the Euro clearing us out and giving us a pretty nice day and the GFS saying "not so fast" to a full drying trend with its chance of some showers nearby.
This upcoming system does not look like a tropical soaker of epic proportions but it does provide the region some needed rainfall -- we could see some one inch totals between the two days in some spots from heaiver shower activity, especially across higher terrain to the north. Locally, half inch totals look doable at this point. Given our general dry trend the past seven weeks, save for a couple of events, this type of rainfall will be appreciated by local gardens and gardeners.
