1. The rich tropical moisture from Miriam and now Tropical Storm Norman will spread into Texas today and this weekend. It's likely that a single identity, which would be Norman, will cross the mountains and move across southern Texas and eventually into the western Gulf of Mexico. On that path, heavy rains will spread from western Texas through the Hill Country into San Antonio and eventually Houston. I can see anywhere from 1-8 inches of rain from that system this weekend across Texas.
That feature will be a trackable feature along the Gulf Coast and eventually the Southeast with heavy rains on the Monday and Tuesday time frame. It will probably weaken coming north into the mid-Atlantic Wednesday and Thursday next week.
2. An upper-level low is still predicted over the Great Lakes this weekend, and that means more waterspouts over the eastern Great Lakes.
3. I posted a map of where snowflakes are possible late next week. With the typhoon recurving in the Pacific, that usually leads to a colder weather pattern a week to 10 days down the road. The air mass coming down next week will certainly be cold enough for upslope snow in Montana and Wyoming, with some snowflakes in the back end of the rain across the northern Plains into the northern Great Lakes.
Damaging ice storm on the way for the lower Mississippi Valley. Another storm will bring more snow and ice problems this weekend.
A cold and wintry weather pattern setting up prior to the Holidays.
Cold air spreads out across much of the country and leads to a battle ground of snow and ice in the East.
Lake snows will be heavy in some of the traditional NW flow locations.
Storm will bring a lot of wild weather the next 24 hours.
