  1. Another strong storm likely impacts the region late Friday into Saturday with another round of moderate to heavy rainfall, and strong, to potentially damaging winds, along with a coastal flooding threat. Another southern stream trough will be moving onshore of the Pacific northwest midweek and track across the country, reaching toward the Great Lakes Region late in the week. With some of the global guidance the upper trough is becoming more negatively tilted during Friday, keeping the surface low a little farther to the west. Timing of the heaviest rainfall and highest winds remains Friday night into Saturday as a low level jet of 50-70kts moves through the region. Also, an occluded low will be moving over the region late Friday night into Saturday morning. Strong lift, and some instability, along with elevated CAPE up to 500 J/kg will allow for a chance of thunderstorms. Precipitable waters also increases late Friday night, up to 1.35 inches, and a period of moderate to heavy rainfall remains possible. The is the potential for another flooding event as WPC has placed most of the area in a slight risk for excessive rainfall. Finally, with the strong winds another high wind event is also becoming more likely. While there are a few days until the onset of this storm impacts are becoming more likely.
