Thursday Preview: Moderating trend begins...next storm system not far away...



We are taking a quick look at the weather for Thursday...first off you can see on the water vapor image of fast, zonal flow across the southern tier of the country. At the surface high pressure is nearly overhead. That high pressure has delivered a cold air mass to the Carolinas. However, changes are beginning today to a milder weather regime...


The water vapor shows a lot of high level moisture from the Pacific streaming east. A strong upper trough is diving into the Pacific Northwest. These two features will help provide a powerful storm system this weekend to bring rain and storms.


However before we get to that, the high level moisture content should result in more clouds for Thursday compared to the past couple days...







At the surface, high pressure and light winds will result in a chilly start. Temperatures will start in the 20's area-wide...











By later in the day that high pressure will begin to assert itself off the Southeast Coastline. Surface winds will veer around to the south and southeast, a milder breeze overall.


The southerly winds will ultimately feed moisture into a developing storm system that could bring rain showers on Friday and then showers and storms on Sunday.






The end result should be a warmer Thursday across the Western Carolinas, a good 7-11 degrees above Wednesday's values. Everyone should finish out the day in the 50's with some increase in clouds...
